Microparticulate feeds for Penaeid larvae
Provedor de dados: 5
Autores: Kanazawa, A.
The mass production of penaeid larvae still depends on live foods such as diatoms, Chlorella and Artemia . However, it requires much facilities, maintenance expenses, and labor to produce a desired amount of life foods safely and constantly. Also, the nutritive value of planktonic organisms is occasionally variable and this makes the use of live food for mass culture restrictive. Therefore, it is necessary to develop microparticulate diets as a substitute for live foods to further increase the productivity of seed for shrimp culture.

A brief review of nutritional studies for Penaeus monodon
Provedor de dados: 5
Autores: Liao, I; Liu, F.
In order to develop effective formulated for Penaeus monodon , sufficient information is needed on its nutritional requirements. Unfortunately, research on this area has been very limited. This paper outlines the results of such research. Since data on the nutritional requirements of P. japonicus are relatively well established, some of these data are also reviewed in this paper and are used as a basis for assessing the nutritional requirements of P. monodon . Protein, lipid, carbohydrate, mineral and vitamin requirements are evaluated from the parameters of growth survival and feed efficiency. Studies on the effects of enzymes and the development of microparticulate diet for larvae are also summarized.

Autores: Della Patrona, Luc.
SODACAL prawn farm which was set up as a pilot farm for the development of a prawn industry in New Caledonia, saw its production exponentially rise from 1984 to 1992 (to 400 t/year, then experienced a sharp drop in 1993 (250 t/year) which carried on until 1997, and finally rose back to a stabilizing level around 400 t/year until 1999. The study analyses the difficulties observed before and during the drop of production. Among them, mortality outbreaks, other biological perturbations (benthic mat clearing and crab and fish mortality) and focus on the noxious state of the bottom (reduced and smelling sulfide hydrogen). It particularly shows that Syndrome 93 outbreaks could be observed on this farm from 1990. The analysis highlights the particular climatic...

The nutritional requirements of the Japanese shrimp Penaeus japonicus
Provedor de dados: 5
Autores: Guillaume, Julien.
Penaeus japonicus is probably the best known species among penaeids or even among shrimps. In juveniles, the protein requirement was best studied and Japanese shrimp appears as the most demanding penaeid species. They may be related to several factors such as energy level of the diet, digestibility or biological value of protein or other nutritional factors. The essential amino acids are well known, however from a quantitative point of view the requirements in each of these amino acids remain to be determined.

A white spot disease-like syndrome in the Pacific blue shrimp (Litopenaeus stylirostris) as a form of bacterial shell disease
Provedor de dados: 5
Autores: Goarant, Cyrille; Brizard, Raphael; Marteau, Anne-laure.
In May 1997, some white lesions evoking the white spot syndrome disease were observed in Litopenaeus stylirostris broodstock in New Caledonia. The occurrence of these lesions was neither associated with mortality, nor with histological evidence of white spot syndrome baculovirus (WSBV), The evidence suggests that these lesions result from a form of bacterial disease and are associated with an increased bacterial flora on the outer surface of the cuticle, as well as an increased incidence throughout the molt cycle. A microscopic observation of these lesions allows them to be differentiated from WSBV-associated lesions.

Enrichment of live foods.
Provedor de dados: 5
Autores: Watanabe, T.
Live foods such rotifers and Artemia are still indispensable for mass propagation of larval fish. At present, more than 20 fish and crustacean species are mass produced in Japanese governmental fish farming centres and private hatcheries. Fry are either released into the coastal areas or used for commercial cultivation. This culture technology is rapidly developing with new species being introduced each year and larval rearing is increasingly identified as the number one constraint. Artemia is used most extensively, particularly for the mass production of Kuruma prawn, Penaeus japonicus .

Assessment of tropical shrimp aquaculture impact on the environment in tropical countries, using hydrobiology, ecology and remote sensing as helping tools for diagnosis
Provedor de dados: 5
Autores: Fuchs, Jacques; Martin, Jean-louis M.; Populus, Jacques.
After a period of rapid development of the sites (an increase in both reared surface area and production), tropical shrimp aquaculture is currently being faced with critical problems due to economical and ecological constraints. In many countries with favourable conditions for shrimp aquaculture such as indonesia or Vietnam, sites are often badly selected and/or over-exploited. This conducts to sorne extent to decreases or collapses in the production due to the difficulty in predicting the maximum production capacity of the sites. Furthermore, it appears that production sustainability depends on many factors among which socio-economy and ecolo gy are of prime importance. The STD3 project titled « Assessment of tropical shrimp aquaculture impact on the...

Mineral requirement of Penaeids
Provedor de dados: 5
Autores: Piedad-pascual, F.
Marine shrimps absorb minerals from their aquatic environment aside from the minerals that come from the food they eat. Thus, the dietary requirement of shrimps for certain minerals will depend on the amounts and availability of these minerals in the aquatic environment. Dietary sources for growth may be necessary due to losses during moltings.

Expériences sur l'influence des sédiments du bassin d'élevage sur la physiologie de Penaeus stylirostris. Rapport des travaux menés du 26 novembre au 7 décembre 1955 à la Station Saint Vincent
Provedor de dados: 5
Autores: Cochard, Jean-claude; Goarant, Cyrille; Boglio, Eric; Lemonnier, Hugues.
The influence of the soil quality of culture pond on the physiological state of Penaeus stylirostris reared in earthen shrimp pond in New Caledonia was investigated by the measurement of the osmoregulatory capacity and magnesium hemolymph concentration of samples of 20 of these shrimp captured in the pond and maintained for 24 or 48h in cages laid on the bottom. A first experiment was affected by the occurrence of a pathology caused by Vibrio penaeicida probably due to initial handling stress. The second experiment showed that the osmoregulatory capacity is depresssed as a function of the soil quality : the more it is reduced the more the depression is important.

Evolution de la communaute bacterienne heterotrophe de l'eau de mer lors d'une experience d'aquaculture de crevettes peneides en systemes clos
Provedor de dados: 5
Autores: Sohier, L; Bianchi, M.
The quantitative and qualitative evolution of the heterotrophic bacterial community of sea water was studied throughout an experimental rearing of Penaeus japonicus in closed systems. Cluster analysis was realised on 417 strains coming from water sampled at different moments of the experiment. This collection includes 40 strains coming from a mussel used for diet and 40 strains coming from the digestive tract of one prawn after six months rearing. Quantitative and qualitative studies have both shown a similar evolution of heterotrophic microflora whatever the initial animal load was. The dendrogram obtained led to a description of characteristics of the various populations constituting the heterotrophic bacterial community of the water environment...

Autores: Mialhe, Eric.
Development of aquaculture has been linked to zootechnical mastering of larval production in hatcheries. Regular and excessive use of antibiotics (antifungal or antibacterial) may thus also be reduced, permitting to limit release of these products in sea-water and, consequently, avoiding progressive selection of resistant-strains.

The role of astaxanthin in shrimp pigmentation
Provedor de dados: 5
Autores: Latscha, T.
Carotenoids are exogenously derived isoprenoid compounds which are responsible for pigmentation in crustaceans. While implants and bacteria are able to synthesize these carotenoids de novo, shrimps like other animals entirely depend on their dietary supply. The major carotenoid found in most crustacean tissues and responsible, e.g. for the typical colour of penaeids is astaxanthin. With increasing industrialization in shrimp farming there is a growing demand for synthetic, nature-identical carotenoids, not only for pigmentation, but also for the maintenance of growth and fertility.

Growth factors in Penaeid shrimp feeding
Provedor de dados: 5
Autores: Guillaume, Julien; Cruz, R; Cuzon, Gerard; Wormhoudt Van, A; Revol, A.
Some nutrients known as non essential in vertebrates could be essential in invertebrates and could be related to some "unknown growth factors" which were evidenced or suspected, mainly in mollusc or crustacean flesh or meal, by several authors working on different species of crustaceans. A set of experiments was carried out in our laboratory in order to isolate one of these factors found in squid meal.

L'exploitation mondiale des crustaces: Bilan et perspectives
Provedor de dados: 5
Autores: Laubier, A; Laubier, Lucien.
Since nearly twenty years, world exploitation of crustaceans increases from 1,263,000 tons in 1968 to 3,419,000 tons in 1985, overcoming the predictions of 1970 by more than one million tons. Penaeid prawns fisheries experienced a very fast development. The krill resource proved to be practically commercially unworkable. By now, the major crustaceans stocks appear fully exploited. During the same period, penaeid aquaculture experienced a fast growth, which should continue in the near future.

Effect of shrimp head meal inclusion level in litopenaeus schmitti juveniles diet.
Provedor de dados: 20
Autores: Jaime Ceballos, B. J.; Fraga Castro, I.; Galindo López, J.; Alvarez Capote, J.S.
This study determined the effect of different shrimp head meal (SHM) levels (0, 5, 15, 25 and 30%) in practical diets for Caribbean white shrimp juveniles Litopenaeus schmitti (0.29 ± 0.0025 g). A totally randomized experimental design was carried out under laboratory conditions during 54 days. There were no significant differences (p &gt; 0.05) in survival of shrimps in all treatments evaluated. This result indicated that SHM included at 5, 15 and 25% in diet promoted growth. The relation of SHM inclusion level in diet with final weight (FW), food conversion rate (FCR) and protein efficiency ratio (PER) were described by the following quadratic equation: FW = 0.8023 + 0.0604 S - 0.0018 S2, 2 =0.81; FCR = 8.0019 - 0.6081 S + 0.0164 S2, R2 =0.82 and PER =...

Proceedings of the Workshop on the Management of the Shallow Water Shrimp  Fishery of Tanzania
Provedor de dados: 20
The fishery is presently comprised of an industrial trawler component and an artisanal component. During 1989 there were sixteen trawlers engaged, two belonging to the parastatal Tanzania Fisheries Corporation (TAFICO) and the rest being foreign-owned. The landings from these vessels included 974 tonnes (whole weight) of shrimp and 1,069 tonnes of fish by-catch. Almost all the shrimp were exported. The wholesale (fob) value of the shrimp was probably in the order of US$ 5.5 million. On the basis of data collected during a socio-economic study undertaken immediately prior to the Workshop, the estimated landings by the about 859 artisanal fishing units in 1989 was 1,212 tonnes of shrimp suitable for export, along with over 3,000 tonnes of fish. An estimate...

En los laboratorios de producción de postlarvas de camarón se suministra, en los estadios de protozoea y mysis, alimento vivo para garantizar buenos resultados en el cultivo sin embargo, el empleo de alimentos artificiales posibilita reducir la costosa dependencia de las algas y los quistes de Artemia ( Wouters et al, 2004). Aunque los resultados alcanzados con diferentes dietas artificiales en el cultivo larval son satisfactorios, aún existe gran preferencia por la utilización del alimento vivo. Sin embargo, en los últimos años con vistas a disminuir los costos de producción, la contaminación y agilizar el proceso productivo, diferentes empresas se han dado a la producción de alimentos artificiales para sustituir parcial (Fegan, 1992) o totalmente el...

Provedor de dados: 20
Autores: Alvarez, J.S.; Hernandez-Llamas, A.; Galindo, J.; Fraga, I.; Garcia, T.; Villareal, H.
The feasibility of substituting soybean meal for ¢shmeal diets for juvenile white shrimp Litopenaeus schmitti (0.35   0.01g) was evaluated, and an adequate substitution level was determined. Five diets were evaluated using 46%, 59%, 75%, 88% and 100% substitution levels. Pellet water stability was signi¢cantly a¡ected by dietary soybean content (Po0.05). Increased soybean content produced lower pellet stability, ranging from a dry matter loss of 14^ 22% after a 2-h immersion, and 20^33% after an 8-h immersion. After 52 days, signi¢cant di¡erences (Po0.05) were found in shrimp weight, feed conversion ratio and protein e⁄ciency ratio. The values were 0.64^1.06 g, 2.8^7.9 and 0.45^1.21, respectively, for the three measurements. Overall, better results were...

Low genetic variability in the fifth introduction  of Litopenaeus vannamei in Cuba, as estimated  with microsatellite markers
Provedor de dados: 20
Autores: Artiles, A.; Rodríguez, I.; Pérez, A.; Pérez, L.; Espinosa, G.
The present work estimated the genetic variability and relatedness index of the fifth stock of Pacific white shrimp,  Litopenaeus vannamei, imported into Cuba for farming purposes from the US Shrimp Improvement System (SIS). Ge- netic variability was estimated by genotyping 33 samples for four microsatellite loci: M1, Pvan 1815, Pvan 0040 and  Pvan 1758. This stock had average expected and observed heterozygosities of 0.37 and 0.27 respectively; the lowest  of all stocks previously introduced in Cuba. The above, together with the low amount of allelic variants detected for  each microsatellite, was suggestive of low genetic variability. In addition, pairwise relatedness coefficients clustered  around unity, indicating a high degree of consanguinity. Taken...

Autores: Galindo, J.; Fraga, I.; de Arazoza, M.; Fajer, E.; González, R.; Forrellat, A.
The effect of diets with different protein levels on the growth of pink shrimp juveniles Penaeus notialis under laboratory conditions was studied. Animals with initial average weight of 0.4 g were fed during 56 days using four isocaloric (350 kcal/100 g) and isolipidic (8.7 %) balanced diets, containing 30, 35, 40 and 45 % of protein. Shrimp fed with the diet containing 45 % of protein reached the highest growth and the best values for nutritional indixes under evaluation. The protein efficiency tended to increase when the protein level in food also increased. A significant relationship was verified between shrimp weight and in vitro digestibility of diets. No relationship was detected between enzimatic activity of trypsin and general proteases for the...

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.

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.

Autores: Lavens, P.; Piyatiratitivorakul, S.; Menasveta, P.; Sorgeloos, P.
The variation in egg quality, i.e. the potential of the egg to produce viable fry, is still a limiting factor in the commercial production of marine fish and crustacean fry. Better knowledge in this field would contribute to improved and especially more consistent hatchery outputs and to the development of more suitable broodstock diets. So far, objective criteria to evaluate egg quality are scarce. However, it is very likely that the nutrient composition of the eggs may be a good indicator for egg viability as it reflects the nutrient demands of the developing embryo and larva. Since (n-3) highly unsaturated fatty acids (HUFAs) have been identified as essential nutrients for the larvae of marine fish, shrimp and prawn a case study has been initiated with...

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.

L-ascorbyl-2-polyphosphate (ApP) was used as a vitamin C source to study the ascorbic acid (AA) requirements for the early postlarval stages of white shrimp (&lt;i&gt;Penaeus vannamei&lt;/i&gt;). First the stability of ApP in the diets was determined: ApP losses after pelletizing and 10 min immersion in seawater were 25-35% and 30%, respectively. Semipurified diets with five levels of ApP (0, 20, 40, 100 and 200 mg kg&lt;sup&gt;-1&lt;/sup&gt; expressed as active AA were fed &lt;i&gt;ad libitum&lt;/i&gt; to &lt;i&gt;P. vannamei&lt;/i&gt; (PL-14 stage, mean dry weight 0.73 mg) for 26 days. Each treatment was run in five replicates. No significant differences in growth were observed among treatments after 26 days of feeding. As of day 19 of feeding, increased...

Abstract: The objective of this work was to evaluate different feeding rates on the productive performance of cobia (Rachycentron canadum) grown in brackish waters. For the experiment, 1,600 juveniles were distributed in 16 enclosures installed in an estuarine pond. Four different feeding rates were evaluated: 1, 3, 5, and 7% live weight (LW) per day. The following performance parameters were assessed: survival, final biomass, specific growth rate, daily weight gain, apparent feed conversion, protein efficiency rate, lipid efficiency rate, and hepatosomatic index. Survival was greater than 80% at all feeding rates. The most efficient feed conversion rate was obtained with the feeding rate of 5% LW per day, which also resulted in better values for the...

Thus, the present study aims to investigate the sodium metabisulphite LC50 - 96 h in the mangrove species Ucides cordatus. Crabs were collected in the tidal creek margins in Bragança estuarine and were submitted to preliminary test (screening) and posterior definitive test. Crabs were exposed in five different concentrations and a control group in five replicates, two crabs per recipient (5 L) during 96 hours. A negative correlation was observed to sodium metabisulphite concentration in relation to dissolved oxygen and pH. At the end of the experiment were obtained the following...

ABSTRACTIt is generally believed that increasing feeding frequency has immediate benefits, including reduced nutrient leaching and increased shrimp growth. In this context, the aim this work was to evaluate the effect of feeding frequency in growth performance of Farfantepenaeus paulensis. Juveniles of Farfantepenaeus paulensis were grown for 30 days in pen enclosures, at a stocking density of 5 shrimp/m2. The shrimp were fed on feeding trays at a rate of 8% of their biomass per day, with treatments of one, two, three and four times per day, with four replicates each. The results showed no differences (5% probability) in biomass gain of F. paulensis when feed was offered two, three or four times per day. However, it was observed that the once a day...

The sodium metabisulphite (SMB) is used in shrimp farming to prevent melanosis and the 5.0 ppm chlorine (CL) concentration used in the shrimp processing is efficient as a bactericide, but there is no evidence of the effectiveness of these chemical compounds as fungicides. Therefore, the aim of this study was to evaluate the in vitro effect of sodium metabisulphite (SMB) and chlorine (CL) on the growth of Aspergillus and Penicillium species isolated from marine shrimp in different stages of processing. The samples were collected from a frozen shrimp processing industry, located in Piauí State, Brazil. The total fungi and occurrence of Aspergillus and Penicillium species were evaluated. For in vitro sensibility test using the diffusion disk in agar method,...
