Bioencapsulation of the antibacterial drug sarafloxacin in nauplii of the brine shrimp <i>Artemia franciscana</i> OMA
Dixon, B.A.; Van Poucke, S.; Chair, M.; Dehasque, M.; Nelis, H.J.; Sorgeloos, P.; De Leenheer, A.P..
Nauplii of the brine shrimp <i>Artemia franciscana</i> were enriched with the antibacterial drug sarafloxacin hydrochloride to determine if levels effective against four pathogenetic strains of <i>Vibrio</i> spp. would accumulate in brine shrimp. Three vibrio strains were <i>Vibrio anguillarum</i>; the fourth was <i>V. vulnificus</i>. Concentrations of sarafloxacin ranging from 1 to 40% (weight: volume) were incorporated into the oil phase of Super Selco brine shrimp diets. Enriched nauplii and controls were sampled at 2h interval for 24h. Antibiotic sensitivity testing was evaluated with a modification of the Kirby-Bauer disk diffusion method. A microbiological assay with <i>Escherichia coli</i>...

Effect of salinity on the uptake of cadmium by the brine shrimp <i>Artemia fransiscana</i> OMA
Blust, R.; Kockelbergh, E.; Baillieul, M..
The effect of salinity on cadmium uptake by the brine shrimp <i>Artemia fransiscana</i> was studied in chemically defined saltwater solutions. Shrimp were acclimated to different salinities and exposed to the metal in solutions of differing salinity and composition. Within each acclimation group, the cadmium uptake decreased with increasing salinity of exposure. Most of this variation was explained by changes in the activity of the free metal ion. Among the acclimation groups, uptake increased by increasing salinity of acclimation. Most of this variation was explained by changes in the permeability of the shrimp. Uptake was not influenced by changes in the osmolarity or the concentration of any of the major cations in the solution. The...

Effect of temperature on the uptake of copper by the brine shrimp, <i>Artemia franciscana</i> OMA
Blust, R.; Van Ginneken, L.; Decleir, W..
The effect of temperature on the uptake of copper by the brine shrimp <i>Artemia franciscana</i> has been studied in chemically defined saltwater solutions. Animals were acclimated to temperatures ranging from 10°C to 35°C and exposed to copper at different temperatures within this range. The results show that within each temperature acclimation group, copper uptake increases with increasing temperature of exposure. Within each temperature acclimation group most of the variation can be related to the combined effect of temperature on the chemical speciation and diffusion rate of copper in the diffusion layer lining the exchange surfaces. The magnitude of the apparent activation energy for copper uptake indicates that it is a facilitated...

Enrichment strategies for <i>Artemia</i> using emulsions providing different levels of n-3 highly unsaturated fatty acids OMA
Han, K.; Geurden, I.; Sorgeloos, P..
Three separate enrichment trials compared the <i>n</i>-3 highly unsaturated fatty acid (HUFA) levels in <i>Artemia franciscana</i> nauplii (Great Salt Lake, USA) as a function of the <i>n</i>-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 <i>n</i> -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). After the 48-h enrichment, the content of docosahexaenoic acid (DHA), eicosapentaenoic acid EPA) and total...

INFLUENCE OF DIFFERENT DIETS ON LENGTH AND BIOMASS PRODUCTION OF BRINE SHRIMP ARTEMIA FRANCISCANA (KELLOG, 1906)A. Boletín de Investigaciones
García-Ulloa Gómez,Manuel; Gamboa Delgado,Julián; Zavala Aguirre,José Luis; Ogura Fujii,Tetsuya; Lavens,Patrick.
Total length and biomass production of the brine shrimp Artemia franciscana were studied fed on soybean and wheat micropulverized meals (applied alone or mixed at different proportions), live microalgae (Tetraselmis suecica and Chaetoceros calcitrans), and dried Spirulina as diets. Eight diets were tested in triplicates during 10 days. Significant differences (P < 0.05) were observed from day 1 onwards. The mixed meal-based diets showed better production results. At day 1, the Artemia nauplii fed on the 70% wheat meal/ 30% soya meal diet were 30% longer compared to the animals from the C. calcitrans group. At day 10, the organisms fed with the 100% soya meal diet were 68% longer than those fed on the C. calcitrans diet. The final biomass production (wet...

International study on <i>Artemia</i> : 41. Influence of culture conditions and specific diapause deactivation methods on the hatchability of <i>Artemia</i> cysts produced in a standard culture system OMA
Lavens, P.; Tackaert, W.; Sorgeloos, P..
Using cyst material produced in an indoor cyst production system from 4 <i>Artemia</i> strains belonging to the species <i>A. franciscana</i> (San Francisco Bay, California, USA; Macau, Brazil; Great Salt Lake, Utah, USA) and <i>A. parthenogenetica</i> (Lavalduc, France), different factors were studied that affect dormancy in brine shrimp cysts. Preliminary experiments under varying (a)biotic culture conditions revealed an interaction between environmental conditions and hatching characteristics. Results obtained under better-defined conditions demonstrated a significant positive correlation between the amount of food available to the adult <i>Artemia</i> populations and the hatchability of their encysted...

International study on <i>Artemia</i>: LII. Incubation of <i>Artemia</i> cyst samples at high temperature reveals mixed nature with <i>Artemia franciscana</i> cysts OMA
Triantaphyllidis, G.V.; Pilla, E.J.S.; Thomas, K.M.; Abatzopoulos, T.J.; Beardmore, J.A.; Sorgeloos, P..
We present evidence that incubation of brine shrimp <i>Artemia</i> 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 (<i>A. fransiscana</i>) 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 <i>A. parthenogenetica, A. sinica, A. urmiana</i> and <i>A. tunisiana</i>. We demonstrate that high temperature incubation can be routinely applied to cysts from natural <i>Artemia</i> populations occurring adjacent to fish and shrimp hatcheries, to determine the extent and...

Modifications ultrastructurales du chorion dans les kystes prehumidifies d'Artemia. ArchiMer
Ultrastructural changes of the chorion were studied in prehydrated Artemia cysts. After incubation for 12, 24, 48 and 72 hours, in hygrostats (under controlled relative humidity, that range from 19% to 99%), the authors observed in cysts that were maintained (for at least 48 h in 99% of relative humidity, some chorionic alveoli containing electron dense structures. They presume that ions and/or molecules migrate during prehydration from inside the cyst to the alveolar layer.

Oxygen bioavailability and haemoglobins in the brine shrimp <i>Artemia franciscana</i> OMA
De Wachter, B.; Blust, R.; Decleir, W..
Bioavailability of oxygen for the saline-water invertebrate <i>Artemia franciscana</i> was studied, since both oxygen concentration and oxygen diffusion rate change with salinity. Total haemoglobin concentration and the relative contribution of each of three haemoglobins was measured in specimens acclimated to different salinities and oxygen concentrations. Both haemoglobin concentration and contribution were influenced by salinity and the group observed (males, females with and females without eggs). Multiple regression analysis showed that total haemoglobin concentration was better correlated with oxygen concentration than oxygen partial pressure. The relative proportions of haemoglobins 1, 2 and 3 were better correlated with oxygen partial...

Solid-phase extraction of ascorbic acid 2-sulfate from cysts of the brine shrimp <i>Artemia fransiscana</i> OMA
Nelis, H.J.; Merchie, G.; Lavens, P.; Sorgeloos, P.; De Leenheer, A.P..
Two producers are described for the solid-phase extraction of ascorbic acid 2-sulfate from cysts of the brine shrimp <i>Artemia</i> . The first one is based on reversed-phase ion pair extraction on an octadecylsilica cartridge using tetrabutylammonium as the counterion, followed by elution with methanol. In the second procedure ascorbic acid 2-sulfate is retained on a DEAE silica cartridge and eluted with 0.1M sodium salicylate. Both approaches were used as part of a quantitative reversed-phase ion pair liquid chromatographic method with detection at 254nm. The anion exchange extraction procedure is superior to its ion pair counterpart in terms of recovery (88.7±3,5% versus 63.0±12.7%), reproducibility (CVs of 3.6-7.7% versus 6.3-18.7%), and...

The metabolic status of diapause embryos of <i>Artemia franciscana</i> (SFB) OMA
Clegg, J.S.; Drinkwater, L.E.; Sorgeloos, P..
The brine shrimp <i><i>Artemia</i> franciscana</i> is widely used in aquaculture and basic research in areas ranging from molecular biology to evolution and ecology. A key of its life history involves the production of encysted embryos whose development is halted (enters diapause) at the gastrula stage. These shelled embryos are released into the aqueous environment where diapause continues until terminated by suitable conditions that produce an "activated embryo", which then can resume development when conditions permit. Very little is known about the metabolism of diapause embryos, in contrast to activated embryos, which have been studied extensively. We have examined selected features of metabolism in diapause embryos produced in...

Toxicological effect from the stem cortex of the amazonic plant soapberry Paullinia clavigera (Sapindaceae) upon three arthropods Ciencia e Investigación Agraria
Pérez,Diana; lannacone,José; Pinedo,Harvey.
Toxicological efifects of four extracts proceeding from the stem cortex of the amazonic plant Paullinia clavigera D.R. Simpson (Sapindaceae) by decoction, ethanolic, chlorophormic and hexanic on three arthropods: Rhynchophoruspalmarían (Linnaeus, 1758) (Curculionidae), Eupalamides cyparissias (Fabricius, 1777) (Castniidae) and Artemia franciscana (Kellog, 1906) (Artemiidae) in Ucayali, Peru were studied. The four extracts at the highest concentration tested were: decoction at a proportion 1:10 (w/v), ethanolic, chlorophormic and hexanic at 100 mg·L-1. Toxic effects were evaluated at 12,24,48 and 72 hours on larvae of III in star of R. palmarum and larvae of II instar of E. cyparissias; and at 24 and 48 hours on nauplii of A. franciscana.
