Fatty acid methyl esters extracted from the cuticular surface of Artemia franciscana (Kellogs, 1906) (Crustacea: Anostraca) increase the swim speed of conspecific males
Provedor de dados: 72
Autores: Tapia,Carola; Parra,Leonardo; Mutis,Ana; Gajardo,Gonzalo; Quiroz,Andrés.
ABSTRACT Previous researches have established that the swim speed of some microcrustaceans is influenced by chemical compounds emitted by conspecifics. We examined the hypothesis that cuticular compounds present on the body surface of A. franciscana, the most widespread member of Artemia genus, play a role in the swim speed of conspecific males. The movements (swim) of one male confronted to a sponge soaked with female or male cuticular extract, were recorded during 30 minutes and the swim speed was determined using a behavioral tracking software (Ethovision 3.1, Noldus Technologies). As a control, the movements of one male confronted to a sponge soaked with salty water or with a mixture of the solvents used in the extraction (chloroform-methanol), was...

Иранский эндемик Артемия урмиана в гиперсоленом озере Кояшское (Крым, Украина): предварительное обоснование заноса птицами
Provedor de dados: 13
Autores: Хоменко, С. В.; Шадрин, Н. В.
In 2004 Iranian endemic species Artemia urmiana, Gunther 1890 (Anostraca, Аrtemiidae) was recorded in large numbers in Lake Koyashskoe (Crimea, Ukraine; 45°2’4” N, 36°11’ 44” E), which is the first finding of the crustacean outside its original range. It was previously thought to be confined exclusively to the water area of Lake Urmia (NW Iran; 37°35’ 28” N, 45°28’ 24” E). Considering the distance (1,111 km) and direction (NW) of spread (Fig. 1) we speculate on the possible role of migratory waterbirds in transporting viable cysts of A. urmiana over the Black Sea based on the analysis of relevant literature and own observations. We came to the conclusion that cysts were spread to the Koyashkoe Lake during spring migration most likely by Shelduck (Tadorna...

Genetic structure of bisexual and parthenogenetic populations of Artemia from Italian brackish-hypersaline waters
Provedor de dados: 5
Autores: Nascetti, G; Bondanelli, P; Aldinucci, A; Cimmaruta, R.
Eight populations of Artemia displaying different reproduction modalities (amphigonic vs. parthenogenetic) and ploidies (diploid vs. polyploid) have been collected from Italian salt-works or brackish coastal lagoons, and their genetic structure has been investigated using allozyme electrophoresis. The results obtained on genetic differentiation showed that the Tyrrhenian bisexual samples (A. salina) are genetically homogeneous even between populations located in relatively faraway sites (Sardinia-Latium), having a moderate gene flow assisted by migratory waterfowl. The parthenogenetic samples (A. parthenogenetica) are genetically well differentiated both from the bisexual ones and among them, even when characterised by the same ploidy. Each sample presents...

Production de juvéniles de bar (Dicentrarchus labrax) en marais. Etude de trois séquences alimentaires de sevrage
Provedor de dados: 5
Autores: Buchet, Vincent; Palvadeau, Hubert; Boussard, O.
Trials on the seabass weaning in atlantic marshes (Roux, 1993), have shown that the use of frozen prey improved this step and reduced his resulting stress. During the present study, which must confirmed these preliminary results, three alimentary sequences were tested. 1) natural zooplankton, weaning pellets, as control, 2) natural zooplankton, inert artemia (intensively produced), weaning pellets, 3) natural zooplankton, natural frozen zooplankton (harvested), weaning pellets. The achieved results show that weaning with intermediary phases (sequences 2 or 3) yield best results. Furthermore the phase with artemia yields, systematically, better results than with harvested zooplankton ; then artemia seems a excellent substitute food representing a...

Action des chocs thermiques sur le developpement d'Artemia
Provedor de dados: 5
Autores: Hernandorena, A.
Heat shocks at 40 degree were delivered to Artemia at the end of embryonic development and at the beginning of postembryonic development and their effects on subsequent development examined. Heat shocks delivered during preemergence development have no effect on subsequent development. Heat shocks delivered to newly hatched nauplii induce anomalies on the morphogenesis of thoracic and genital appendages. The induction of morphological anomalies by thermal conditions prevailing during early larval life makes it easier to integrate the morphological effects previously induced by nutritional conditions imposed to older feeding stages.

Selection of lactic acid bacteria as candidate probiotics and in vivo test on Artemia nauplii
Provedor de dados: 5
Autores: Lamari, Faouzi; Sadok, Khouadja; Bakhrouf, Amina; Gatesoupe, Joel.
Lactic acid bacteria (LAB) were isolated from rotifer cultures in a marine hatchery to search for potential probiotics for marine animals. Fifteen strains were first selected among a total of 55, according to antibacterial activity against Vibrio sp. Among eight strains identified as Lactobacillus casei, four were highly adhesive, suggesting some ability for surface colonization. The other strains were identified as Lactobacillus plantarum, Lactobacillus dextrinicus, and Leuconostoc sp. To validate probiotic potential, Artemia were challenged against pathogenic Vibrio alginolyticus, with or without one of six selected LAB strains. The six strains protected Artemia against the pathogen, to some extent on condition that nutrient enrichment was provided. La....

Utilisation de bactéries lactiques probiotiques pour prémunir les poissons d'élevage contre des vibrions pathogènes
Provedor de dados: 5
Autores: Lamari, Faouzi.
Diseases cause major production losses in fish farms. Bacteria of the genus Vibrio are known as opportunistic pathogens, and have been associated with mass-mortality episodes. To cope with these disease outbreaks, fish farmers often resort to the use of antibiotics. However, preventive overuse has led to the emergence of resistant strains and frequent treatment failures. Probiotic lactic acid bacteria are increasingly used to improve the quality of seed production in aquaculture, while limiting antibiotic treatments. Microbial strains must fulfil several criteria to be evaluated as potential probiotics.In a first step, we selected and characterized 55 strains of lactic acid bacteria isolated from fish hatchery. The first selection criterion focused on the...

Probiotic and formaldehyde treatments of Artemia nauplii as food for larval pollack, Pollachius pollachius
Provedor de dados: 5
Autores: Gatesoupe, Joel.
Formaldehyde was used to disinfect Artemia cysts and nauplii, while introducing two probiotics in the enrichment process: Bactocell (Pediococcus acidilactici) and Levucell (Saccharomyces cerevisiae). The disinfectant was selected due to its potential compatibility with probiotics, since it was more effective against Gram-negative bacteria than against lactic acid bacteria and yeast. However, the presence of formaldehyde reduced the intake of P. acidilactici in Artemia. Consequently, the disinfection was stopped before Bactocell supplementation to the nauplii fed to pollack (Pollachius pollachius) larvae. The mean weight of pollack was higher with this probiotic treatment. Growth was even better with the combination of Levucell and Bactocell, but the yeast...

Evaluation of microdiets versus live feeds on growth, survival and fatty acid composition of larval haddock (Melanogrammus aeglefinus)
Provedor de dados: 5
Autores: Blair, Tammy; Castell, Fisheries And Oceans Canada; Neil, Steven; D'Abramo, Louis; Cahu, Chantal; Harmon, Paul; Ogunmoye, Kehinde.
Until recently, it was considered impossible to feed newly hatched marine fish species with a compound diet. Substituting a compound diet for live prey was performed several weeks after hatching, depending on the species. Compound diets were well ingested at the early stage but larvae died with a gut full of food, suggesting that larvae were unable to digest the compound diet. The hypothesis was that younger larvae have insufficient digestive enzymes to thrive on compound diets, and that exogenous enzymes, provided from live prey, are necessary for early stages.  The organogenesis of marine fish larvae is not completely achieved at hatching and histological studies have revealed that the anatomy of the digestive tract undergoes developmental changes over...

Contribution a l'etude de l'elevage de la crevette rose Palaemon serratus (Pennant) en captivite.
Provedor de dados: 5
Autores: Campillo, Albert.
The growth of post-larval P. serratus has been studied until the appearance of secondary sexual characters, in order to eliminate the influence of sex ratio on the mean wt. The influence of temp on intermolt period and number of molts was observed in male and female kept individually. Different sorts of food of natural origin have been tested. The rearing of post-larval lots metamorphosed at different times of the yr showed that the growth of P. serratus is conditioned not only by the temp, but also by the season. The food conversion ratio was defined in relation to the sex and age of the prawns. Shelters allowed the author to obtain a ratio of survival which varied post-larvae per square meter. The sex ratio established from several breedings as soon as...

Exploitation et optimisation de la production des cystes du crustacé "Artemia tunisiana" (bowen et sterling, 1978) dans la saline de Sfax
Provedor de dados: 20
Autores: Aloui, N.; Amorri, M.
La saline de Sfax constitue le meilleur site pour l’exploitation et la production d’Artemia en Tunisie. La production de cystes est exploitée chaque année pour être utilisée dans l’alimentation des larves de poissons. Cette production est estimée à 30 kg de cystes poids sec. Toutefois, lors de nos campagnes de récolte, nous avons enregistré de grandes pertes de cystes occasionnées par les vents emportant les cystes qui seront mélangés avec le sable.    Afin de minimiser les pertes et optimiser la production naturelle de la saline, nous avons jugé utile, d’installer des barrages dans les coins des bassins à Artemia pour s’opposer à l’action du vent. Par ailleurs, nous avons fait un suivi mensuel de l’abondance des cystes récoltés et de quelques paramètres...

RESUME La saline de Sfax constitue un site potentiel pour l’exploitation et la production de l’Artemia locale. Des quantités importantes d’Artemia sont exploitées chaque année (60 kg de cystes poids sec) et sont utilisées en alimentation larvaire.  Afin de démontrer l’impact de divers rejets industriels, agricoles dans cette saline, nous avons procédé à la détermination de quelques métaux traces toxiques : le mercure (Hg), le cadmium (Cd), le plomb (Pb), le cuivre (Cu) et le zinc (Zn) par une analyse en spectrophotométrie  d’absorption atomique, ce qui nous permettra d’évaluer le degré de contamination par ces métaux dans les cystes et la biomasse d’Artemia.  Les résultats obtenus ont montré que les concentrations aussi bien au niveau des cystes que de la...

Autores: Ben Naceur, H.; Ben Rejeb Jenhani, A.; Romdhane, M .S.
Le branchiopode Artemia représente le principal organisme vivant colonisant les biotopes hypersalés. L’étude taxonomique de l’Artemia au niveau de la région ouest méditerranéenne, incluant l’Italie, la France, l’Espagne, le Portugal et le Maroc, a révélé la présence de l’espèce Artemia franciscana (qui a pour origine le continent Américain) comme étant une espèce invasive. Dans ce travail, une nouvelle population d’Artemia a été rapportée pour la première fois au niveau de Sabkhet Halk El Manzel. Une première identification taxonomique de cette population a été réalisée moyennant une étude morphologique et comparative de la forme de l’ovisac des femelles avec cinq autres populations tunisiennes appartenant à l’espèce Artemia salina et avec l’espèce...

&lt;i&gt;Artemia&lt;/i&gt; in aquatic toxicology: a review
Provedor de dados: 27
Autores: Persoone, G.; Wells, P.G.
Due to commercial availability of dried cysts from which live test material can be hatched at will, &lt;i&gt;Artemia&lt;/i&gt; is used extensively in research and applied toxicology.Despite the extensive literature on dose-effect relationships of chemicals on brine shrimp, it was not until 1980 that an experimental protocol was developed for a simple acute toxicity test with &lt;i&gt;Artemia&lt;/i&gt; nauplii, meeting the prerequisites for standardization.The reliability and accuracy of this short-term test were determined during an intercalibration exercise involving 80 laboratories and were found to be quite satisfactory. Consequently, the so-called ARC-test, which is one of the very few standardized marine toxicity tests, is now used routinely at the...

International study on &lt;i&gt;Artemia&lt;/i&gt; : 17. Energy consumption in cysts and early larval stages of various geographical strains of &lt;i&gt;Artemia&lt;/i&gt;
Provedor de dados: 27
Autores: Vanhaecke, P.; Lavens, P.; Sorgeloos, P.
Variations in dry weight, caloric content and ash content during cyst hatching and early larval development have been studied for various geographical strains of &lt;i&gt;Artemia&lt;/i&gt; . In general, decapsulated cysts contain 30 to 40% more energy than freshly hatched nauplii; for Chaplin Lake and Buenos Aires &lt;i&gt;Artemia&lt;/i&gt; this difference amounts to 57%. Ash contents increase as decapsulated cysts hatch into instar I and molt into instar II-III nauplii. Over a 24h larval developmental period individual dry weights and energy content of the nauplii decrease with 16-34% and 22-37% respectively.A small but significant correlation exists between the survival rate of starved nauplii and either the energy content of instar I and instar II-III...

Improvements in the decapsulation of &lt;i&gt;Artemia&lt;/i&gt; cysts
Provedor de dados: 27
Autores: Bruggeman, E.; Baeza-Mesa, M.; Bossuyt, E.; Sorgeloos, P.
As described in our previous paper (Sorgeloos et al. , 1977) hypochlorite can be used as reactive agent to dissolve the lipoproteic chorion of &lt;i&gt;Artemia&lt;/i&gt; cysts. Two commercial products are available worldwide, i.e. bleaching powder, chloride of lime Ca(OCL)&lt;sub&gt;2&lt;/sub&gt; and bleaching water NaOCl solutions. In Western Europe the latter product is the cheapest, whereas in the USA and Southeast Asia bleaching powder should be considered. Because the decapsulation process is a much more critical operation with bleaching powder, especially with regard to the viability of the embryos (Bruggeman et al., in preparation; Manzi, personal communication), we studied the use of technical NaOCl solutions in detail.

Isolated embryonic membranes (i.e. the outer cuticular membrane, the fibrous layer, the inner cuticular membrane and the hatching membrane) and homogenates of incubated, decapsulated cysts of 16 populations from five &lt;i&gt;Artemia&lt;/i&gt; species (Crustacea, Anostraca) were examined by sodium dodecyl-sulphate polyacrylamide gel electrophoresis. Characteristic differences in major polypeptides between 45 and 205 kD were seen. These differences might be used as markers for identification of different &lt;i&gt;Artemia&lt;/i&gt; species. The validity of this approach in characterizing &lt;i&gt;Artemia&lt;/i&gt; populations is discussed.

Autores: Verschuere, L.; Dhont, J.; Sorgeloos, P.; Verstraete, W.
&lt;i&gt;Artemia&lt;/i&gt; juveniles were cultured under intensive conditions in three series of six tanks at different times. Both plate counts and Biolog GN microtitre plates were used to monitor the microbial community. Repetitions of the &lt;i&gt;Artemia&lt;/i&gt; cultures in time revealed significant differences in Biolog patterns and bacterial counts, showing that normal culture practices, including chlorination of the sea water, does not allow control of the associated microbial community. However, the similarity among the Biolog fingerprints of all 18 tanks as determined by the Pearson correlation coefficient was always high. Both observations together indicate that the microbial community which colonizes the culture tanks seems to be determined by...

Roles and potentials of &lt;i&gt;Artemia&lt;/i&gt; in coastal saltworks
Provedor de dados: 27
Autores: Sorgeloos, P.; Tackaert, W.
The recent developments in aquaculture production of fish and shrimp have resulted in increased demands for &lt;i&gt;Artemia&lt;/i&gt; cysts and biomass as valuable sources of life food. Solar salt works are suitable biotopes for the integrated exploitation of salt, &lt;i&gt;Artemia&lt;/i&gt; and eventually fish or shrimp. &lt;i&gt;Artemia&lt;/i&gt; may be present as a natural resource in local saltworks; however in some situations characteristics of the endemic strain might justify the introduction of another &lt;i&gt;Artemia&lt;/i&gt; species to increase productivity.

The influence of temperature and salinity on the sensitivity of &lt;i&gt;Artemia&lt;/i&gt; nauplii to chemical compounds
Provedor de dados: 27
Autores: Persoone, G.; Van Steertegem, M.
The toxicity of chemicals to aquatic organisms is mostly determined in a set of experimental conditions which are close to optimal for the test species. Because in nature organisms have to cope with fluctuating environmental conditions which can range during the course of the year from optimal to suboptimal, up to the limits of the tolerance range, the conditions under which routine bioassays are normally performed do, however, not reflect the large range of situations occurring in the field. Considering the scarcity of information on the effect of fluctuating environmental conditions on the sensitivity of test species to toxicants, a comparative laboratory study has been undertaken to determine the combined influence of environmental variables on the...

Low nutrient availability is not the single factor limiting &lt;i&gt;Artemia&lt;/i&gt; cyst productivity in salinas of NE-Brazil
Provedor de dados: 27
Autores: Camara, M.R.; Tackaert, W.
&lt;i&gt;Artemia&lt;/i&gt; production in NE-Brazil began in 1977 after a successful inoculation of &lt;i&gt;Artemia franciscana&lt;/i&gt; (San Fransisco Bay, California, USA) in solar salt ponds in Macau (RN state) and was followed by a rapid natural dispersion of this crustacean to all saltwork areas in the region. &lt;i&gt;Artemia&lt;/i&gt; is basically produced in extensive conditions as an opportunistic by-product collected from salt evaporation ponds. This type of approach has, however, brought about very unpredictable results, as is reflected in a drastic decline of cyst production occurring from 1982 onwards. Low nutrient concentrations and a drop in primary productivity have been suggested as possible causes for this decline. In order to provide a...

Too frequently, reference is made to &lt;i&gt;Artemia salina&lt;/i&gt;. This binomial refers to a European species which may be extinct. Most scientific studies are, however, based on the New World species &lt;i&gt;Artemia franciscana&lt;/i&gt;. We estimate that over 90% of the studies in which &lt;i&gt;Artemia&lt;/i&gt; is used as experimental test organism or as food source deal with this particular species, very often using material from the Great Salt Lake in Utah, USA.

International study on &lt;i&gt;Artemia&lt;/i&gt; : 48. The effect of temperature on cyst hatching larval survival and biomass production for different geographical strains of brine shrimp &lt;i&gt;Artemia&lt;/i&gt; spp.
Provedor de dados: 27
Autores: Vanhaecke, P.; Sorgeloos, P.
The effect of temperature on different geographical strains of &lt;i&gt;Artemia&lt;/i&gt; has been studied for the following criteria: the hatchability of the cysts, the resistance of the larvae to high temperature (34°C) and the biomass production of larvae cultured under standard conditions. Experimental temperatures ranged from 25° to 37°C for the hatching criteria and from 20° to 32.5°C for the biomass production.Both the hatching percentage and growth performance are affected by temperature. However, the relative and quantitative impact of temperature varies widely among &lt;i&gt;Artemia&lt;/i&gt; strains. This is also the case for the temperature resistance of the larvae. The impact of increasing temperatures on cyst hatching as well as the...

Freshly-hatched &lt;i&gt;Artemia&lt;/i&gt; nauplii from various geographical sources survived storage in a refrigerator (2-4°C) at densities of 2000 per ml and above. Except for &lt;i&gt;Artemia&lt;/i&gt; from Chaplin Lake and Buenos Aires, naupliar viability was very high even after 48 h storage, and did not decrease significantly after a 24 h post-storage transfer to 25°C. Neither the naupliar dry weight nor biochemical composition changed significantly during refrigeration for most strains tested. Comparative culture-tests with stored and freshly-hatched nauplii as food for juvenile marine mysids &lt;i&gt;Mysidopsis bahia&lt;/i&gt; M. and larval carp &lt;i&gt;Cyprinus carpio&lt;/i&gt; L. revealed similar production performances.

Although there exists an obvious inclination to replace live larval food by formulated feeds, &lt;i&gt;Artemia nauplii&lt;/i&gt; are still essential in the larviculture of marine fish species. So far, on-grown &lt;i&gt;Artemia&lt;/i&gt; are rarely used in larviculture although they offer several advantages over &lt;i&gt;Artemia nauplii&lt;/i&gt;: e.g. they contain a higher individual protein and energy content thus improving the fish larvae's energy budget; an equal amount of live food is reached with far less individuals thus a considerable saving of &lt;i&gt;Artemia&lt;/i&gt; cysts; their composition of (n-3) highly unsaturated fatty acids (HUFA) may easily be improved by applying enrichment techniques.

Provedor de dados: 27
Autores: Han, K.; Geurden, I.; Sorgeloos, P.
Three separate enrichment trials compared the &lt;i&gt;n&lt;/i&gt;-3 highly unsaturated fatty acid (HUFA) levels in &lt;i&gt;Artemia franciscana&lt;/i&gt; nauplii (Great Salt Lake, USA) as a function of the &lt;i&gt;n&lt;/i&gt;-3 HUFA level in the emulsion (30% and 50%), the enrichment dose (0.05, 0.1, 0.2, 0.3 and 0.4 g1-1) and the degree of dilution of a high HUFA emulsion with an &lt;i&gt;n&lt;/i&gt; -3 HUFA-free emulsion (100/0, 50/50, 25/75, 12.5/87.5 and 0/100, HUFA-rich/HUFA-free, w/w). The standard emulsions were distributed by the International Council for the Exploration of the Sea, Working Group on the Mass Rearing of Juvenile Fish (ICES).

Effects of hydrogen peroxide treatment in &lt;i&gt;Artemia&lt;/i&gt; cysts of different geographical origin
Provedor de dados: 27
Autores: Van Stappen, G.; Lavens, P.; Sorgeloos, P.
Short-term treatment with peroxide solutions has been tested as a chemical way to break the diapause of &lt;i&gt;Artemia&lt;/i&gt; cysts of different species and geographical strains. The methodology was further standardized by analyzing the impact of the cyst hydration level and the application conditions (concentration, duration, temperature) on the hatching percentage. The peroxide treatment was most effective in deactivating diapause when applied on fully hydrated cysts, and showed a quantitative nature: a maximal positive effect was obtained for specific combinations of peroxide concentration and exposure time. The peroxide effect was preserved after processing and storage of treated cysts. The biochemical mechanisms possibly involved in induction and...

Improvements in the decapsulation technique of &lt;i&gt;Artemia&lt;/i&gt; cysts
Provedor de dados: 27
Autores: Bruggeman, E.; Sorgeloos, P.; Vanhaecke, P.
Because bleaching powder is the cheapest source of hypochlorite in many countries of the world, a decapsulation procedure has been worked out in which technical calciumhypochlorite Ca(OCl)&lt;sub&gt;2&lt;/sub&gt; is utilized.A standard procedure has been developed for the deactivation of the chlorine residues adsorbed on the decapsulated cysts. Proper dehydration and storage of the decapsulated cysts assure maximum viability of the embryos in diapause. A prototype system for routine decapsulation and processing of large quantities of cysts is proposed.Beneficial effects of the decapsulation process on both the hatching percentage and the individual dry weight of the hatched nauplii are discussed in detail.

The use of brine shrimp &lt;i&gt;Artemia&lt;/i&gt; in biological management of solar saltworks
Provedor de dados: 27
Autores: Tackaert, W.; Sorgeloos, P.
In recent years, there has been a growing awareness of the hydrobiological aspects of the solar salt production process. Saltworks are man-managed artificial ecosystems that are highly vulnerable to biological disturbances, including uncontrolled proliferation of microalgae resulting in a reduced evaporation and contamination of the salt with gypsum and insoluble organic materials.Optimal production of solar salt, both in terms of quality and quantity, requires a well-established balance between the primary and secondary producers, with brine shrimp &lt;i&gt;Artemia&lt;/i&gt; grazing on phytoplankton constituting the major interaction. In this paper, we discuss the beneficial role of &lt;i&gt;Artemia&lt;/i&gt; in balancing the hydrobiological activity of...

Provedor de dados: 27
Autores: Vanhaecke, P.; Sorgeloos, P.
For characterization of strains of the brine shrimp &lt;i&gt;Artemia&lt;/i&gt; of different geographical origin, a standard culture test has been developed in order to compare statistically growth and survival of larvae of different strains. 25 geographical strains have been studied so far -including, for 3 strains, analyses of cysts harvested at different times. Important differences in rates of growth and survival were observed between strains but not among batches of the same strain. Best performances were noted for strains from Bahia Salinas (Puerto Rico), Buenos Aires (Argentina), Chaplin Lake (Canada), Great Salt Lake (Utah, USA), Galera Zamba and Manaure (Colombia).

Autores: Romdhane, M.S.; Devresse, B.; Léger, Ph.; Sorgeloos, P.
Larvae of the freshwater prawn (&lt;i&gt;Macrobrachium rosenbergii&lt;/i&gt;) were reared to post-larvae in a closed recirculation system. Six treatments were designed where freshly-hatched &lt;i&gt;Artemia&lt;/i&gt; nauplii were first given to the larvae for 3, 7, 11, 15, 17 and 25 days according to the treatment. After that (omega-3) HUFA-enriched &lt;i&gt;Artemia&lt;/i&gt; were given until the 28th day at which time the test was terminated and evaluated. The requirement for (omega-3) Highly Unsaturated Fatty Acids (HUFA) for the larval stages of &lt;i&gt;M. rosenbergii&lt;/i&gt; was confirmed by this experiment. Moreover, the longer the period of feeding on (omega-3) HUFA-enriched &lt;i&gt;Artemia&lt;/i&gt; nauplii , the better the results in terms of...

Samplings were organized in three marine fish hatcheries. Samples were taken at different steps during the production of algae, rotifers and &lt;i&gt;Artemia&lt;/i&gt; . There were 233 dominant colony types isolated for further characterization. The isolates were compared to each other and to reference strains of &lt;i&gt;Photobacterium, Vibrio&lt;/i&gt; and &lt;i&gt;Alteromonas&lt;/i&gt;, using cellular fatty acid fingerprints. Fatty acid profiles of the isolates were grouped using principal component analysis. The isolates fell into at least ten major groups, of which two correspond to the genera &lt;i&gt;Vibrio&lt;/i&gt; and to &lt;i&gt;Alteromonas&lt;/i&gt;, respectively. Some groups seem to be restricted to a particular type of live food or isolation...

The ARC-test: a standardized short-term routine toxicity test with &lt;i&gt;Artemia&lt;/i&gt; nauplii: methodology and evaluation
Provedor de dados: 27
Autores: Vanhaecke, P.; Persoone, G.
Considering the need for reliable standardized routine toxicity tests for the marine environment, a short-term bioassay with &lt;i&gt;Artemia&lt;/i&gt; nauplii has been developed for routine testing. The major reason for the selection of brine shrimp as test species is the continuous availability of &lt;i&gt;Artemia&lt;/i&gt; under the form of dry cysts from which the larvae are hatched very easily. This unique advantage solves one of the major problems of aquatic ecotoxicological tests, namely stock recruitment and/or culturing; the &lt;i&gt;Artemia&lt;/i&gt; test can be performed anywhere and at any time from dry biological material available "on the shelf".An extensive study has been performed on various brine shrimp tests published in scientific...

Two experiments were performed in order to determine the effect of supplementation of dry foods with live &lt;i&gt;Artemia&lt;/i&gt; nauplii on the growth, survival, rate of cannibalism, and length-weight relationships of &lt;i&gt;Clarias gariepinus&lt;/i&gt; larvae. It was found that &lt;i&gt;Artemia&lt;/i&gt; -supplementation resulted in a significantly higher growth rate. The "condition", expressed as a length-weight relationship, was likewise altered after supplementation. The survival and rate of cannibalism were not influenced by supplementation. &lt;i&gt;Artemia&lt;/i&gt; -supplementation of dry foods was compared with other approaches which are based on the concept of the 'adaptation weight'.

In finfish mariculture, seed production and larval rearing still form the bottleneck for all ongrowing operations and are considered as the main limiting factor for industrial development. Through trial and error more than through biological understanding two opposite hatchery techniques have been developed which surprisingly control a multiparametric combination of different factors but aspire to the same objective of conformity with wild standards and the cost-effective production of larvae. In intensive aquaculture, the rearing technique is characterised by high initial larval densities in small tanks under strict hydraulic, thermic, and nutritional conditions. The light conditions are artificial. The temperature and quality of water are controlled. The...

Provedor de dados: 27
Autores: Sorgeloos, P.; Remiche-Van der Wielen, C.; Persoone, G.
Because of their easy hatching from dry cysts and their year-round availability, nauplii of the brine shrimp &lt;i&gt;&lt;i&gt;Artemia&lt;/i&gt; salina&lt;/i&gt; are most convenient test organisms for toxicity studies. The bioassays mentioned in literature have, however, mostly been carried out with larvae of which neither the exact instar stage nor the geographical origin is known. The incubation of the cysts should always be carried out under strictly controlled temperature conditions since both the onset of hatching and the length of the hatching period are temperature-dependent. Moreover, the experiments should only be carried out with populations of nauplii of the same stage of development since it is demonstrated that the second and third instars are...

Total body extracts and hemolymph of &lt;i&gt;Artemia&lt;/i&gt; were purified by solvent partition and column chromatography. Moulting-hormone concentrations were then determined by a specific radioimmunoassay (RIA). Results are expressed in ng ecdysteroid activity/g fresh weight (or per ml). Initially, the RIA data on extracts of adults were highly variable. The use of a more accurate sampling technique based on the reproductive cycle of the females allowed to determine a hormone activity pattern.In females, moulting cycles alternate with vitellogenic cycles. The lowest values of ecdysone (3-6 ng ecdysone equivalents/g fresh body weight or ml hemolymph) occur during...

In this study, one-cycle and multi-cycle culture systems for &lt;i&gt;Artemia&lt;/i&gt; in seasonal salt ponds are compared. In one-cycle systems, &lt;i&gt;Artemia&lt;/i&gt; is inoculated only once per season, while in multi-cycle systems ponds are drained and re-stocked several times per season. In Vietnam, three-cycle systems gave significantly higher cyst yields than did the one-cycle system. However, after two cycles, systems were not significantly different. Food limitation probably caused the steady decline in cyst yields, as observed in the one-cycle ponds. In these ponds, females have smaller broods (from the second cycle onwards) and during the last cycle the number of adult females is lower than in multi-cycle ponds.

This paper reports on enrichment techniques oriented towards a specific DHA accumulation in the live prey &lt;i&gt;Brachionus plicatilis&lt;/i&gt; and &lt;i&gt;Artemia sp.&lt;/i&gt; The product used in these experiments (DHA7) is an experimental emulsion with a DHA/EPA ratio 6.7:1. Rotifers enriched with this pure DHA7 emulsion contained up to 69 mg/g DW DHA and a DHA/EPA ratio of 1.6. The DHA/EPA ration could be increased to a much higher level by different enrichment techniques. Dilution of the DHA7 emulsion with coconut oil prior to enrichment also had a beneficial effect on the DHA/EPA ratio of the rotifers. Using a mixture DHA7/coconut oil 3:7 the DHA/EPA ratio could be raised to 4.9. In &lt;i&gt;Artemia&lt;/i&gt; DHA levels were slightly influenced...

A scanning electron microscopy (SEM) study of bisexual &lt;i&gt;Artemia&lt;/i&gt; populations revealed that populations representing the species &lt;i&gt;A. franciscana, A. persimilis, A. urmiana, A. sinica&lt;/i&gt; and a recently described species from Kazakhstan have a pair of spine-like outgrowths at the basal parts of their penes, whereas populations from Southern Europe and North Africa (i.e. Mediterranean populations) lack these spine-like outgrowths. Allozyme and DNA polymorphisms, detected by allozyme starch gel electrophoresis and AFLP fingerprinting, respectively, suggested conspecificity of the studied populations from the broader Mediterranean basin.

Autores: Tackaert, W.; Vanhaecke, P.; Sorgeloos, P.
A standard method has been developed to produce F&lt;sub&gt;1&lt;/sub&gt;-generation cysts from different zygogenetic strains and their cross-breeds. The F&lt;sub&gt;1&lt;/sub&gt; cysts were used to determine the quantitative heritability of the following characteristics: cyst hatchability, cyst diameter, larval growth, and temperature resistance of the freshly-hatched nauplii.Data are given for cysts produced from nine strains and seven cross-breeds. Important differences for all characteristics studied were noted between the cross-bred and the parental strains.

International study on &lt;i&gt;Artemia&lt;/i&gt;: 19. Hatching data for ten commercial sources of brine shrimp cysts and re-evaluation of the "hatching efficiency" concept
Provedor de dados: 27
Autores: Vanhaecke, P.; Sorgeloos, P.
A comparative hatching study has been carried out with reference &lt;i&gt;Artemia&lt;/i&gt; cysts as well as cysts from Argentina, Australia, Brazil, Canada, France, Italy, the People' s Republic of China, the Philippines and the USA. Hatching rate, percentage and efficiency vary considerably from one cyst source to another. These hatching criteria are, however, not strainspecific since significant variation is found among cyst batches from the same geographical origin. The limitations of the "hatching efficiency" concept are discussed and a new criterion "hatching output", i.e. the biomass of nauplii expressed in mg dry weight produced per gram cyst product, is proposed for evaluation of the hatching quality of &lt;i&gt;Artemia&lt;/i&gt; cyst brands.

Provedor de dados: 27
Autores: Lim, L.C.; Soh, A.; Dhert, P.; Sorgeloos, P.
This paper describes a pilot culture system for the production of on-grown &lt;i&gt;Artemia&lt;/i&gt; in freshwater ornamental fish farms. The system had 21 culture units, each consisting essentially of three components: an oval-shaped raceway, an air-water lift system and two waste collectors. Using artificial seawater at 20 ppt for culture and at a mean production rate of 3 kg/m&lt;sup&gt;3&lt;/sup&gt; of water in a 12-day cycle, the system had a production capacity of 8 metric tons of on- grown &lt;i&gt;Artemia&lt;/i&gt; a year. Biochemical analyses were preformed to evaluate the nutritional value of the on-grown &lt;i&gt;Artemia&lt;/i&gt; against three conventional live feeds, viz. live &lt;i&gt;Artemia&lt;/i&gt; nauplii, live &lt;i&gt;Moina&lt;/i&gt;...

Seventeen geographical strains of &lt;i&gt;Artemia&lt;/i&gt; , 13 bisexual and 4 parthenogenetic, were cultured through sexual maturity to select a strain which gives the best production in the St. Croix Artificial Upwelling- Mariculture System. Individual strains were compared for survival, growth, and time to sexual maturity. Dry and ash weight were determined on 100 couples (bisexual) or 200 females (parthenogenetic) from each strain. Total biomass (dry weight) production per strain has also been determined. Five strains were compared for the percent protein content of sexually mature individuals. On the basis of the results obtained, the best strains for use in the St. Croix System are the bisexual &lt;i&gt;Artemia&lt;/i&gt; from Macau (Brazil), San...

Occurrence of &lt;i&gt;Artemia&lt;/i&gt; in nature and its morphological development from nauplius to adult

Autores: Sorgeloos, P.
The first written record of the existence of the brine shrimp only dates back to 1755 (Schlosser in Kuenen and Baas-Becking, 1938). Nonetheless this "filtering animal" was already known since much longer times by different ethnic groups who attributed a better salt production in the brine pools to the presence of &lt;i&gt;Artemia&lt;/i&gt; ; hence its popular names such as brineworm, Salztierchen, verme de sale, sóféreg, Bahar el dud, Fezzanwurm, etc. Despite the primitive optical equipment available at that time Schlosser's drawings were very detailed and rightly give the adult animal 11 pairs of thoracopods. Several other scientists, including Linnaeus (1758), later described adult &lt;i&gt;Artemia&lt;/i&gt; with only 10 thoracopods. This controversy...

Autores: Vanhaecke, P.; Siddall, S.E.; Sorgeloos, P.
The brine shrimp inhabits geographically isolated biotopes with specific biotic and abiotic conditions. This has resulted in various geographical strains between which marked genetica, biological and chemical differentiation exists. The response of 13 different &lt;i&gt;Artemia&lt;/i&gt; strains to the combined effect of temperature and salinity has been studied. Experimental temperatures tested ranged from 18 to 34°C and salinities from 5 to 120 promille. Except for Chaplin Lake (Canada) &lt;i&gt;Artemia&lt;/i&gt; , all strains showed high survival over a wide range of salinities (35-110 promille). For all strains the common temperature optimum was between 20 and 25°C. Interaction between temperature and salinity was negligible or very limited....

We present evidence that incubation of brine shrimp &lt;i&gt;Artemia&lt;/i&gt; encysted embryos (cysts) at high temperatures (36-37°C) suppresses hatching of cysts from a parthenogenetic population, while at the same time allowing cysts of the New World bisexual species (&lt;i&gt;A. fransiscana&lt;/i&gt;) to hatch. This approach is used to verify the presence of contaminating foreign material from the New World in natural cyst populations of Old World &lt;i&gt;A. parthenogenetica, A. sinica, A. urmiana&lt;/i&gt; and &lt;i&gt;A. tunisiana&lt;/i&gt;.

Few shrimp hatcheries successfully propagate captive broodstock on a commercial scale. Diets for acceptable maturation performance of &lt;i&gt;Penaeus vannamei&lt;/i&gt; have typically relied on the inclusion of marine polychaetes (bloodworm) from Panama or Maine, USA, which are expensive and are of unpredictable supply. Studies were therefore undertaken at experimental and commercial scale to replace or supplement the polychaetes by frozen ongrown &lt;i&gt;Artemia&lt;/i&gt; which were either non-enriched or bioencapsulated with specific boosters. In experiment 1 the control diet consisted of frozen squid only and was evaluated against broodstock diets where 60% of the squid was substituted by bloodworm or enriched &lt;i&gt;Artemia&lt;/i&gt; biomass....

Preparation and use of &lt;i&gt;Artemia&lt;/i&gt; as food for shrimp and prawn larvae
Provedor de dados: 27
Autores: Dhont, J.; Lavens, P.; Sorgeloos, P.
The brine shrimp,&lt;i&gt;Artemia&lt;/i&gt; has played a significant role in the expansion of the commercial production of shrimp and prawn during the last decade. Being an off-the-shelf and easily usable live food,&lt;i&gt;Artemia&lt;/i&gt; is the main alternative for the natural diet of shrimp larvae. It appeared in the late 1970s that the nutritional value of &lt;i&gt;Artemia&lt;/i&gt;, especially for marine organisms, is not constant, but varies both geographically and temporally, causing unreliable outputs in marine larviculture. Through multidisciplinary studies in Japan and by the International Study on &lt;i&gt;Artemia&lt;/i&gt;, both the causes for nutritional variability in &lt;i&gt;Artemia&lt;/i&gt; and methods to improve poor-quality...

&lt;i&gt;Artemia cysts&lt;/i&gt; from 4 geographical strains were incubated under standard hatching rates increased with increasing light intensities. The light-intensity threshold at which the maximal hatching rate was attained, varied from strain to strain. Differences in light sensitivity between the &lt;i&gt;Artemia&lt;/i&gt; strains studied can, at least partly, be attributed to variation in chorion characteristics. The hypothesis is discussed that light might act as a diapause inhibitor in marine and freshwater branchiopods.

The influence of light on the hatching induction of &lt;i&gt;Artemia&lt;/i&gt; cysts is well known. Our objective was to determine the absorption characteristics of the responsible photoreceptor by action spectroscopy. The results suggest the involvement of a haemopigment located in the gastrula. Haematin, the haemopigment of the cyst shell is demonstrated to have a light-screening function towards the photoreceptor.

The importance of highly unsaturated fatty acids (HUFA) such as 20:5omega3 and 22:6omega3 has been investigated for the larvae of the blue shrimp &lt;i&gt;Penaeus stylirostris&lt;/i&gt;. HUFA-rich or HUFA-enriched &lt;i&gt;Artemia&lt;/i&gt; nauplii yielded higher production results in the hatchery than HUFA-poor &lt;i&gt;Artemia&lt;/i&gt; especially when yeast was used as a substitute for algae during the early larval stages. Best results were obtained when a HUFA-rich formulated diet was used as a supplement to the yeast and as an enrichment for the &lt;i&gt;Artemia&lt;/i&gt; nauplii. Differences in production results could be attributed to the HUFA content in living and non-living larval diets.

Autores: Thoeye, C.; Van der Linden, A.; Bernaerts, F.; Blust, R.; Decleir, W.
The temperature in a natural &lt;i&gt;Artemia&lt;/i&gt; habitat usually shows diurnal cyclic variations. It is important for inoculation and culturing purposes to know the survival under such conditions. The survival of four &lt;i&gt;Artemia&lt;/i&gt; strains, Great Salt Lake and San Francisco Bay (USA), and Sfax and Mégrine (Tunisia) was studied over a period of 7 days, in different conditions of constant or diurnal fluctuating temperatures at two salinities. For the Great Salt Lake strain, the temperature fluctuation had no effect on the survival, as compared to constant temperature regimes (at 35 pro mille). For the other strains, temperature fluctuations had either no influence, or a beneficial influence on survival. In general, the tolerance of...

The influence of aqueous copper chemistry on the uptake and toxicity of copper in &lt;i&gt;Artemia&lt;/i&gt;
Provedor de dados: 27
Autores: Blust, R.; Bernaerts, F.; Van der Linden, A.; Thoeye, C.
The effect of organic complexation, salinity, and pH on the uptake and toxicity of copper in &lt;i&gt;Artemia&lt;/i&gt; was studied. The results were compared with data on the chemical speciation and lipid solubility of copper in saline solutions.The uptake experiments took 90 min and the toxicity tests 24h. A computer model was used to calculate the saline solution equilibrium speciation. The lipid solubility of copper was determined in a series of saline/olive oil partition tests.Complexation of copper by EDTA reduced the uptake and toxicity of copper. Salinity had no apparent effect on both processes. The results of these uptake and toxicity experiments agreed well with the copper speciation and lipid solubility data. The effect of pH on the uptake and...

International study on &lt;i&gt;Artemia&lt;/i&gt; : 35. Techniques to manipulate the fatty acid profile in &lt;i&gt;Artemia&lt;/i&gt; nauplii, and the effect on its nutritional effectiveness for the marine crustacean &lt;i&gt;Mysidopsis bahia&lt;/i&gt; (M.)
Provedor de dados: 27
Autores: Léger, P.; Naessens-Foucquart, E.; Sorgeloos, P.
The importance of essential fatty acids for the early larval stages of cultured marine fish and crustacean larvae is well documented. In this regard, the variability in essential fatty acid content of their live prey &lt;i&gt;Artemia&lt;/i&gt; is critical.This paper describes different techniques for improving the fatty acid profile in &lt;i&gt;Artemia&lt;/i&gt; nauplii using microparticles and emulsions as enrichment diets. These diets can be applied during the incubation of the cysts and/or after the separation of the nauplii. After enrichment, the nauplii not only contain high levels of the essential fatty acid 20:5 omega 3 (up to 13.5% or 35.2 mg/g) but also considerable levels of 22:6 omega 3 (up to 7% or 18.1 mg/g), another essential fatty acid which...

Autores: Sorgeloos, P.
Simple to construct and inexpensive high density culturing techniques are described for culturing 2000 &lt;i&gt;Artemia&lt;/i&gt; nauplii in 1-1 bottles; 25,000 in 1-1 bottles and 50,000 in 30-1 plastic sheet cylinders. Frozen &lt;i&gt;Dunaliella&lt;/i&gt; or dried &lt;i&gt;Scenedesmus&lt;/i&gt; cells are used as food. Growth results of these high density cultures are comparable with the best growth data reported in literature. The latter however refer to low-density experiments.

Considering the necessity for standardization of toxicity tests and the need for simple and reliable routine tests, the &lt;i&gt;Artemia&lt;/i&gt; Reference Center at the State University of Ghent in Belgium has developed a short term standard toxicity test with &lt;i&gt;Artemia&lt;/i&gt; nauplii. This simple and inexpensive bioassay which can be used as a screening test to determine the toxicity of chemicals to aquatic organisms, has been discussed in detail during a special workshop devoted to toxicity tests with brine shrimp, at the occasion of the "International Symposium on the brine shrimp &lt;i&gt;&lt;i&gt;Artemia&lt;/i&gt; salina&lt;/i&gt;"(Corpus Christi, Texas, USA; August 1979).

Design, operation, and potential of a culture system for the continuous production of &lt;i&gt;Artemia&lt;/i&gt; nauplii
Provedor de dados: 27
Autores: Lavens, P.; Sorgeloos, P.
A flow-through system is described for the controlled production of &lt;i&gt;Artemia&lt;/i&gt; nauplii. High densities of adult brine shrimp are induced to ovoviviparity through diet manipulation, optimal culture water exchange, and high constant oxygen levels. The nauplii produced are separated from the culture tank effluents in a special recuperation filter system. The culture water is recirculated over a rotating biodisc, a cross-flow sieve, and a plate separator.The potential of this nauplii production system for application in aquaculture hatcheries is discussed.

Provedor de dados: 27
Autores: Vanhaecke, P.; Persoone, G.; Claus, C.; Sorgeloos, P.
Standardization of toxicity tests on aquatic organisms to detect the impact of chemicals on freshwater or marine ecosystems is an urgent necessity. From the variety of methods, criteria, and test species proposed, simple standardized tests for algae, crustaceans, and fish are now close to being adopted at the international level for the freshwater environment. Despite the same urgency, very little has been achieved for the marine environment. &lt;i&gt;Artemia&lt;/i&gt; is an extremely suitable test-species since, contrary to all other organisms, it does not require continuous maintenance of stock cultures. Unfortunately none of the &lt;i&gt;Artemia&lt;/i&gt; toxicity tests that have been worked out so far can be adopted as such as a representative standard...

Experiences on importance of diet for shrimp postlarval quality
Provedor de dados: 27
Autores: Lavens, P.; Sorgeloos, P.
This paper gives an overview of own experiences with respect to the impact of dietary conditions on the quality of postlarval penaeid shirmp. Direct nutrient-specific effects are documented for highly unsaturated fatty acid (HUFA), phosphatidyl choline (PC) and ascorbic acid (AA). Specific immunostimulants may also contribute to an improved stress resistance of the shrimp fry. Last, but not least, some emphasis is placed on the role of the microflora during the hatchery rearing, the possible reduction of bacteria in the live food adminstered, and the use of probionts through the diet.

An improved separator box for &lt;i&gt;Artemia&lt;/i&gt; nauplii and other phototactic invertebrates
Provedor de dados: 27
Autores: Persoone, G.; Sorgeloos, P.
1. A simple cylindrical hatching and separator box is described for &lt;i&gt;Artemia salina&lt;/i&gt;nauplii (and other phototactic invertebrates), in which the "corner seeking effect" responsible for poor separation is avoided, and from which nauplii can be recovered very conveniently. 2. Separation is achieved by partly unscrewing an internal and closed cylinder from its fixed counter-part glued to the bottom of the box, till two slits are freed through which the nauplii migrate from the darkened internal hatching cylinder into the illuminated exterior compartment. Rescrewing the former cylinder separates the larvae from debris and unhatched eggs.

A fluidized bed dryer for processing &lt;i&gt;Artemia&lt;/i&gt; cysts at the temperatures above 40°C is described and evaluated. The design is directed towards electronic temperature regulation and optimal design of the drying unit. The described fluidized bed dryer proves to be reliable for cyst processing, using inflow air temperatures up to 90°C. The use of this elevated temperature ensures a higher drying rate, resulting in a drying capacity more than 4 times higher than when using inflow air of 40°C. Electronic temperature regulation resulted in a large flexibility of the temperature regime inside the drying unit.

&lt;i&gt;Artemia&lt;/i&gt; cysts have been collected from different saltworks and natural salt lakes in Tunisia. The cyst material was processed and used for the following characterization analyses: cyst and naupliar biometrics, cyst hatching characteristics, fatty acid pattern of the nauplii, nutritional value of the nauplii for mysid shrimp, naupliar growth rate and temperature resistance, mode of reproduction, and characterization of sibling species. The cross-breeding tests and cyst biometrics reveal that only &lt;i&gt;Artemia tunisiana&lt;/i&gt; occurs in Tunisia. Although quality improvements may be expected through improved harvesting, Tunisian &lt;i&gt;Artemia&lt;/i&gt; have acceptable hatching characteristics and are a good food for mysid shrimp....

The possibility to develop a routine batch culturing method for the production of cysts has been examined at laboratory scale. The influence of abiotic and biotic parameters on the mode of reproduction has been studied and the following facts have been noted: - cyclic low oxygen tensions induce haemoglobin synthesis with subsequent shift of the mode of reproduction from ovoviviparity to oviparity; - addition of ferric-EDTA stimulates haemoglobin synthesis;- a correlation exists between the color of the animals and the type of reproduction; - neither the food source nor the water salinity &lt;i&gt;per se&lt;/i&gt; control the mode of reproduction. However, cysts produced at low salinity appear to have a low hatchability. The effect on the hatchability of...

Baker's yeast as a potential substitute for live algae in aquaculture diets: &lt;i&gt;Artemia&lt;/i&gt; as a case study
Provedor de dados: 27
Autores: Coutteau, P.; Lavens, P.; Sorgeloos, P.
In this study baker's yeast was evaluated as a substitute for live &lt;i&gt;Dunaliella tertiolecta&lt;/i&gt; algae in the culture of the brine shrimp &lt;i&gt;Artemia&lt;/i&gt; . Consumption of fresh baker's yeast resulted in poor growth and survival of brine shrimp. However, the nutritional value of the yeast significantly improved after complete removal of the yeast cell wall by enzymatic treatment. Baker's yeast was also made digestible for &lt;i&gt;Artemia&lt;/i&gt; by simple chemical treatment which did not reduce rigidity of the yeast cell. The external mannoprotein layer of the yeast cell wall is probably the major barrier to digestion by &lt;i&gt;Artemia&lt;/i&gt; .

Much progress has been made in the last decades in the industrial farming of several species of marine fish. The pioneering country has been Japan with the red seabream, however, in the last decade Europe made quick progress with seabass and gilthead seabream. Today Japan is still the biggest producer of marine fish fry with about 200 million fry per year, 70% of the production consisting of red seabream and Japanese flounder. Without any doubt, the most significant progress achieved during the last decade has been the result of improved nutrition, more particularly through the manipulation of the fatty acid profile of the live preys &lt;i&gt;Brachionus&lt;/i&gt; and &lt;i&gt;Artemia&lt;/i&gt; by application of enrichment or boosting techniques with...

High densities of brine shrimp &lt;i&gt;Artemia&lt;/i&gt; can be cultured in flow-through systems using the effluent of microalgae cultures as a combined source of culture medium and food. It has been proven at the "St. Croix Artificial Upwelling Mariculture Project" that in comparison with the fast growing clam &lt;i&gt;Tapes japonica&lt;/i&gt;, brine shrimp assure a much more efficient conversion of plant into animal biomass. It appears from the given examples that microalgae conversion into brine shrimp &lt;i&gt;Artemia&lt;/i&gt; offers efficient and economic applications.

&lt;i&gt;Penaeus monodon&lt;/i&gt; postlarvae (PL-5 to PL-15) were fed 5 different diets consisting of enriched &lt;i&gt;Artemia nauplii&lt;/i&gt; with a specific n-3 HUFA content. Although the postlarvae grew well on an &lt;i&gt;Artemia&lt;/i&gt; diet with low HUFA-content, the ability of PL-10 to endure osmotic stress remained low. Feeding &lt;i&gt;Artemia&lt;/i&gt; enriched with medium levels of n-3 HUFA (sum n-3 HUFA =12,55mg/g DW) for 5 days considerably enhanced the resistance of PL-10 to osmotic stress and their survival recorded 5 days later. However, very high dietary levels of n-3 HUFA (31,2 mg/g DW) did not have any growth promoting effect, thus suggesting that an excessive supply of n-3 may not be beneficial to the shrimp. Our data demonstrate...

A simple semi flow-through culture technique for the controlled super-intensive production of &lt;i&gt;Artemia&lt;/i&gt; juveniles and adults
Provedor de dados: 27
Autores: Dhert, P.; Bombeo, R.; Lavens, P.; Sorgeloos, P.
A simple semi flow-through &lt;i&gt;Artemia&lt;/i&gt; culture unit is described for possible integration in marine fish and shellfish hatcheries as a source of a cheap nursery diet. The system does not require the use of feeding pumps and involves minimal care. Food preparation and addition to the feeding tank is reduced to one or two manipulations per day during the meta-nauplius stages (day 1-3) and the juvenile stages (day 4-14), respectively. Biomass productions are superior to those reported to those for stagnant culture systems and are comparable to those demonstrated for flow-through culture units. This simple rearing technique offers the possibility of producing brine shrimp populations with a uniform size. Furthermore, by varying the feeding...

Eleven morphometric and one meristic character in 15 parthenogenetic &lt;i&gt;Artemia&lt;/i&gt; populations have been studied by using discriminant and cluster analysis as well as scanning electron microscopy. Discriminant analysis revealed five main groups of morphological patterns: (i) the coastal Chinese populations together with a population from Kazakhstan, (ii) the inland Chinese salt lake populations, (iii) the Greek populations, (iv) one African population from Namibia and (v) a Chinese population from Xuyu (Jiangsu province). Cluster analysis was not always in agreement with discriminant analysis and these results are discussed.

Ensiled &lt;i&gt;Artemia&lt;/i&gt; biomass: a promising and practical feed for penaeid shrimp postlarvae
Provedor de dados: 27
Autores: Abelin, P.; Tackaert, W.; Sorgeloos, P.
Unlike &lt;i&gt;Artemia nauplii&lt;/i&gt; which are used extensively as convenient live feed in aquaculture, large-scale utilization of &lt;i&gt;Artemia&lt;/i&gt; juveniles and adults (biomass) is still very limited and in most cases restricted to those operations which are located near an &lt;i&gt;Artemia&lt;/i&gt; production site. Currently applied techniques for preservation of &lt;i&gt;Artemia&lt;/i&gt; biomass (e.g. blast-freezing or drying) are often cost prohibitive and in several cases not applicable at the remote and scattered sites where the &lt;i&gt;Artemia&lt;/i&gt; biomass is available. An inexpensive technique which can be readily applied under field conditions and allowing to stabilize and retain the nutritional quality of...

Cofeeding of phospholipids to turbot &lt;i&gt;Scophthalmus maximus&lt;/i&gt; L. larvae as a tool to reduce live food consumption
Provedor de dados: 27
Autores: Dhert, P.; González Félix, M.; Van Ryckeghem, K.; Geurden, I.; Thysen, F.; Lebegue, E.; Lavens, P.; Sorgeloos, P.
The possible benefits of feeding a formulated diet, together with &lt;i&gt;Artemia&lt;/i&gt; , to first-feeding turbot larvae were investigated. Five dietary regimes were used: control ( &lt;i&gt;Artemia&lt;/i&gt; only), cofeeding with a diet rich in phospholipid (PL) from bovine brain, cofeeding with a diet rich in free fatty acids (FFA) from the same source, cofeeding with a commercial diet (Lansy A2), and a formulated feed only (PL-rich diet). All treatments with artificial diets and the control treatment that received &lt;i&gt;Artemia&lt;/i&gt; exclusively gave a similar survival rate of the fish at day 29. Cofeeding with artificial diets resulted in a lower growth rate than the control treatment. Cofeeding the larvae with PL-rich or FFA-rich diets did...

Autores: Coutteau, P.; Sorgeloos, P.
Details are given of experiments conducted to determine the effects of tank culture conditions on the feeding of &lt;i&gt;Artemia&lt;/i&gt;. Mechanical disturbance, animal density and water quality were found to affect the feeding rate of &lt;i&gt;Artemia&lt;/i&gt;. The importance of culture conditions in maintaining a rate of food consumption which does not limit the growth of the brine shrimp is stressed.

Proposal for a short-term toxicity test with &lt;i&gt;Artemia&lt;/i&gt; nauplii
Provedor de dados: 27
Autores: Vanhaecke, P.; Persoone, G.; Claus, C.; Sorgeloos, P.
Although standardization of toxicity tests on aquatic organisms is an urgent necessity, very little has yet been achieved for the marine environment. As a first step in this direction, a simple, inexpensive and reliable short-term routine test with &lt;i&gt;Artemia&lt;/i&gt; larvae is proposed. This test is the result of an extensive study in our laboratory, taking into account the advantages and disadvantages of &lt;i&gt;Artemia&lt;/i&gt; bioassays published by various authors. The major advantage of the brine shrimp as a test species is its continuous availability under the form of dry cysts which can be hatched very easily; this eliminates all biological, technological, and financial problems of stock recruitment and/or culturing. The acute test...

Autores: Verschuere, L.; Rombaut, G.; Huys, G.; Dhont, J.; Sorgeloos, P.; Verstraete, W.
The use of juvenile &lt;i&gt;Artemia&lt;/i&gt; as feed in aquaculture and in the pet shop industry has been getting more attention during the last decade. In this study, the use of selected bacterial strains to improve the nutritional value of dry food for &lt;i&gt;Artemia&lt;/i&gt; juveniles and to obtain control of the associated microbial community was examined. Nine bacterial strains were selected based on their positive effects on survival and/or growth of &lt;i&gt;Artemia&lt;/i&gt; juveniles under monoxenic culture conditions, while other strains caused no significant effect, significantly lower rates of survival and/or growth, or even total mortality of the &lt;i&gt;Artemia&lt;/i&gt; . The nine selected strains were used to preemptively colonize the...

Evidence for the induction of cyst diapause by heat-shock in &lt;i&gt;Artemia&lt;/i&gt; (International study on &lt;i&gt;Artemia&lt;/i&gt;: 48)
Provedor de dados: 27
Autores: Abatzopoulos, Th.; Triantaphyllidis, G.; Sorgeloos, P.; Clegg, J.S.
The brine shrimp &lt;i&gt;Artemia&lt;/i&gt; produces embryos (cysts) in a state of obligate dormancy called diapause. Diapause is terminated by a variety of treatments, including dehydration. Previous work suggested that some cysts can be induced to reenter diapause when exposed to prolonged anoxia. Results presented in this paper indicate that heat shock (42-43°C) can also lead to diapause induction. The basis for this proposal is the finding that the final hatching level of heat-shocked cysts is increased by a post-heat dehydration, a treatment known to terminate diapause. The respiration rate of postheat-shocked cysts was found to be much lower than controls. Electrophoretic profiles of proteins in extracts from control and heatshocked cysts suggest...

Provedor de dados: 27
Autores: Vanhaecke, P.; Sorgeloos, P.
The nutritional value of fresh hatched nauplii from nine geographical strains of brine shrimp, &lt;i&gt;Artemia&lt;/i&gt; , was determined for larvae of the carp (&lt;i&gt;Cyprinus carpio&lt;/i&gt;). After 2 weeks of culture, the survival of carp larvae was over 90% and no significant differences in survival among treatments were detected. The growth rate of the larvae, however, was a function of the &lt;i&gt;Artemia&lt;/i&gt; strain used. The highest weight gains were recorded with parthenogenetic &lt;i&gt;Artemia&lt;/i&gt; , to the lowest with Chaplin Lake brine shrimp and intermediate results with the other bisexual strains. With the exception of the Chaplin lake strain, the growth results were positively correlated with the size and weight of the...

The intensity of past biological activity can be correlated with the occurrence of suspended and sedimented barite (BaSO&lt;sub&gt;4&lt;/sub&gt;). To date, there is a lack of information on the processes controlling the production of pelagic barite. During the EPOS-2 cruise (November-December 1988), situated in the Scotia Sea-Weddell Sea Confluence, suspended water samples were taken for analysis of total Ba by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and for scanning electron microscopy-electron microprobe (SEM-EMP).The vertical profiles of particulate barium generally show a Ba maximum between 200 and 500 m. SEM-EMP investigation on Scotia-Weddell Sea Confluence profiles provide a possible explanation for the origin of this...

The use of &lt;i&gt;Artemia&lt;/i&gt; cysts in aquaculture: the concept of "hatching efficiency" and description of a new method for cyst processing
Provedor de dados: 27
Autores: Sorgeloos, P.; Persoone, G.; Baeza-Mesa, M.; Bossuyt, E.; Bruggeman, E.
The quality of brands of &lt;i&gt;Artemia&lt;/i&gt; cysts should be expressed on a weight basis, namely the number of live nauplii hatching out per unit of weight of product and not as a "hatching percentage" since the latter concept does not take into account the degree of impurity of the material. A standardized method for the determination of the hatching efficiency is proposed. A new methodology for cyst processing has been worked out at laboratory scale, based on a 2-step cleaning (brine and tap water) followed by dehydration (air or brine) or decapsulation and dehydration (brine).

Among the live diets used in the larviculture of fish and shellfish, the brine shrimp &lt;i&gt;Artemia&lt;/i&gt; nauplii constitute the most widely used food item; i.e., over 700 metric tons of dry &lt;i&gt;Artemia&lt;/i&gt; cysts are annually marketed worldwide for on-site hatching into 0.4 mm nauplii.Although the use of &lt;i&gt;Artemia&lt;/i&gt; appears to be simple, considerable progress has been made in the past decade in improving and increasing its value as a larval diet for marine fish larvae. The improvements include: identification of the most appropriate strains and batches; new techniques for cyst disinfection; decapsulation and hatching; and enrichment and cold storage of nauplii.

Provedor de dados: 27
Autores: Vanhaecke, P.; Sorgeloos, P.
A comparative study has been carried out on the hatching rate of &lt;i&gt;Artemia&lt;/i&gt; cysts of different geographical origin and on different batches of the same source. Substantial variation, among as well as within geographical strains, indicates that the hatching-rate criterion is not strain specific. In an attempt to identify the parameters which influence the hatching rate, it was found that the cyst-drying technique as well as the storage conditions may significantly affect this criterion. It has also been demonstrated that the cysts' hatchability is influenced by their previous drying and storing conditions. Optimal hatching results are guaranteed when a fluidized bed dryer is used and the cysts are stored under vacuum or nitrogen.

Use of ongrown &lt;i&gt;Artemia&lt;/i&gt; in nursery culturing of the tiger shrimp
Provedor de dados: 27
Autores: Dhert, Ph.; Bombeo, R.B.; Sorgeloos, P.
Juvenile and adult &lt;i&gt;Artemia&lt;/i&gt; produced in a semi flow-through culture system were used as food for postlarval shrimp. The growth performance of shrimp reared on such ongrown &lt;i&gt;Artemia&lt;/i&gt; live prey is identical to the growth obtained when feeding newly hatched &lt;i&gt;Artemia&lt;/i&gt; . However, a significantly better stress resistance is obtained when the postlarvae are exposed to a low salinity in a stress test. Besides nutritional and energetic advantages, the use of &lt;i&gt;Artemia&lt;/i&gt; biomass for feeding postlarval shrimp also results in improved economics as expenses for cysts and weaning diets can be reduced.

The significance of carotenoid accumulation in crustacean eggs remains obscure, particularly because neither eggs nor female animals have been found to display specific pigment patterns in relation to reproduction. We report here the first example of carotenoids found exclusively in the ovaries, the eggs, and the hemolymph, but not in the carcass of a female, reproductively active crustacean, i.e. the brine shrimp &lt;i&gt;Artemia&lt;/i&gt; . These pigments are virtually absent in males and in immature animals and disappear very rapidly in growing nauplii following hatching of encysted embryos. Within the cysts, they are preferably localized in the yolk platelets. We have identified them as mono-&lt;i&gt;cis&lt;/i&gt;-canthaxanthins on the basis of their...

Efeito da oferta de náuplios de Artemia franciscana enriquecidos com ácidos graxos poliinsaturados sobre o desenvolvimento de pós-larvas do camarão marinho Farfantepenaeus paulensis
Provedor de dados: 96
Autores: Pontes,Cibele Soares; Andreatta,Edemar Roberto.
O objetivo deste trabalho foi avaliar a eficácia da técnica de enriquecimento de náuplios de Artemia franciscana, em emulsões de ácidos graxos poliinsaturados (AGP) para a alimentação de pós-larvas do camarão marinho Farfantepenaeus paulensis. Este procedimento visou o acréscimo dos ácidos eicosapentaenóico (EPA) e docosahexaenóico (DHA), essenciais para organismos marinhos, mas deficientes na composição de náuplios provenientes de ecossistemas aquáticos continentais. Os náuplios foram divididos em cinco tratamentos: um grupo controle, composto por indivíduos recém-eclodidos, e quatro grupos enriquecidos cada um com as emulsões Selco, Super Selco, AlgaMac 2000 e emulsão formulada em laboratório à base de óleo de fígado de bacalhau, e então ofertados às...

Provedor de dados: 96
Autores: Tesser,Marcelo Borges; Portella,Maria Célia.
Este estudo foi realizado com o objetivo de comparar a influência dos estímulos visual e/ou químico de náuplios de Artemia e de dieta microencapsulada sobre a taxa de ingestão da dieta microencapusulada por larvas de pacu Piaractus mesopotamicus. Utilizou-se um esquema fatorial 7 x 4 (estímulos e idades) com duas repetições. Verificou-se efeito da idade das larvas e dos estímulos, mas não houve efeito para a interação idade &lt;FONT FACE=Symbol&gt;´&lt;/FONT&gt; estímulos. O estímulo químico da Artemia e ambos os estímulos da Artemia resultaram em maior taxa de ingestão de dieta inerte. Resultado intermediário foi obtido com o estímulo visual da dieta microencapsulada.

Coadaptation: lessons from the brine shrimp Artemia, "the aquatic Drosophila" (Crustacea; Anostraca)
Provedor de dados: 97
Autores: GAJARDO,GONZALO; BEARDMORE,JOHN A.
During the fifties Brncic and the Dobzhansky's school, using the fruit fly Drosophila as a test organism, introduced the term integration of the genotype, or genetic coadaptation, which has had great impact on thinking in today's evolutionary biology. In this work we use the brine shrimp Artemia - in many respects a sort of aquatic Drosophila- as a model organism to evaluate the relationship between population structure, potential for divergence and the degree of morphological and/or genetic change. These aspects, tightly linked with the organization of the genotype, are important to understanding how recombination and adaptive release of genetic and phenotypic variation affect the speciation process in Artemia. Analysis of genetic (allozyme, diploid and...

Evaluación de la calidad bacteriológica del alimento vivo (Artemia, Daphnia, Tenebrio y Tubifex) para peces en los sitios de su recolección, producción y venta
Provedor de dados: 108
Autores: Negrete Redondo,Pilar; Monroy Dosta,Carmen; Romero Jarero,Jorge.
Los cíclidos constituyen el grupo de peces de mayor importancia para la acuicultura de ornato. Con el propósito de incrementar la producción de estas especies, los productores deben satisfacer las necesidades metabólicas que proporcionarán a los peces mayor tolerancia a las variaciones en los factores fisicoquímicos del medio ambiente que los rodea, así como más resistencia a las enfermedades. Los acuicultores incluyen alimento vivo, como parte de la dieta de los peces, por su alto contenido en proteína, sobre todo en las primeras etapas de su desarrollo. Los organismos de mayor uso en la acuicultura como alimento vivo son: Artemia, Daphnia, Tubifex y Tenebrio; sin embargo, y a pesar de ser una probable fuente de contaminación de ictiopatógenos, no se...

Effect of prey concentrations and feed training on production of Hoplias lacerdae juvenile
Provedor de dados: 42
Autores: LUZ,RONALD K.; PORTELLA,MARIA CÉLIA.
The aim of this work was to investigate the effects of daily prey concentration during the first 15 days of active feeding of Hoplias lacerdae larvae, and the juvenile size on the feed training. In the first phase, the larvae received five Artemia nauplii concentrations (P). In the second phase, the juveniles from each treatment were trained to accept formulated diet. Superior growth was related to higher initial daily prey concentrations (900 and 1100 nauplii larvae-1). During feed training, the growth tendency was similar to that verified in the first phase. The lowest values of specific growth rate (SGR) were registered after the introduction of the semi-moist diet used in the feed training. However, the values of SGR recovered along the experiment and...

Use of Pseudomonas stutzeri and Candida utilis in the improvement of the conditions of Artemia culture and protection against pathogens
Provedor de dados: 58
Autores: Abdelkarim,Mahdhi; Kamel,Chaieb; Fathi,Kammoun; Amina,Bakhrouf.
To evaluate the effect of two bacterial strains isolated from Artemia cysts and yeast (Candida utilis) on the survival, growth and total biomass production of its larvae, challenge tests were performed with Candida utilis, Pseudomonas stutzeri and Pasteurella haemolityca. In addition, a pathogenic strain of Vibrio alginolyticus was tested for comparative purposes. Pseudomonas stutzeri and Candida utilis have no impact on survival, but enhance growth and total biomass production of the larvae. However, we noted that Pasteurella haemolityca affect negatively Artemia larvae. The adhesion and antagonism assay demonstrates that Candida utilis and Pseudomonas stutzeri are fairly adherent and play an important role in the enhancement of the protection of Artemia...
