| Three nutritional experiments were carried out to investigate the effect of dietary phosphatidylcholine (PC) on the growth (length, weight, and metamorphosis) and survival (rearing and stress) of larval and postlarval <i>Penaeus japonicus</i> Bate. Purified soybean phosphatidylcholine (SPC, 95% purity), hen-egg PC (EPC, 94% purity), and de-oiled soybean lecithin (DSL, PC 23% purity) were used as sources of dietary PC. The results indicated that optimal metamorphosis in larval <i>P. japonicus</i> was obtained at levels of 15-30 g kg<sup>-1</sup> of dietary SPC. Feeding trials with postlarval <i>P. japonicus</i> showed that low levels of dietary SPC (15 g kg<sup>-1</sup>) were more beneficial than... |

| Larvae of the freshwater prawn (<i>Macrobrachium rosenbergii</i>) were reared to post-larvae in a closed recirculation system. Six treatments were designed where freshly-hatched <i>Artemia</i> 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 <i>Artemia</i> 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 <i>M. rosenbergii</i> was confirmed by this experiment. Moreover, the longer the period of feeding on (omega-3) HUFA-enriched <i>Artemia</i> 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 <i>Artemia</i> . There were 233 dominant colony types isolated for further characterization. The isolates were compared to each other and to reference strains of <i>Photobacterium, Vibrio</i> and <i>Alteromonas</i>, 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 <i>Vibrio</i> and to <i>Alteromonas</i>, respectively. Some groups seem to be restricted to a particular type of live food or isolation... |

| In this study we report on the known <i>Artemia</i> habitats worldwide. Recent literature information is incorporated about the taxonomic status of the various populations studied. The genus is composed of di-, tri-, tetra- and pentaploid parthenogenetic populations and of the following bisexual species, <i>A. franciscana franciscana</i>, <i>A. franciscana monica</i>, <i>A. franciscana</i> sp., <i>A. persimilis</i>, <i>A. salina, A. urmiana, A. sinica</i> and <i>A.</i> sp. from Kazakhstan. The problems of characterizing new brine shrimp populations are discussed. In view of the great importance of <i>Artemia</i> as part of the live food chain for the culture of... |

| The effects of high levels of ascorbic acid (AA) delivered through enriched live food has been verified through the successful culture of larval giant freshwater prawn, <i>Macrobrachium rosenbergii</i> Two successive feeding trials were set up using a control (550 µg AA g<sup>-1</sup> DW) and two different AA-enrichment levels in <i>Artemia</i> (1300 and 2750 µg AA g<sup>-1</sup> DW). Under standard culture conditions, no differences in growth nor survival could be observed demonstrating that the nutritional requirements are below 550 µg AA g<sup>-1</sup> DW, which is the normal level occurring in freshly-hatched <i>Artemia</i> . However, a significantly positive effect could be... |

| The rotifer feeding regime for larval turbot could be improved by more regular feeding and adjusted food distributions as to prevent overfeeding and digestion problems. All tests were successfully run in clear-water conditions indicating that the administration of algae is not essential during the rotifer stage. Larval requirements with respect to (n-3) RUFA, and more specifically DRA and DRA/EPA ratio appeared to change according to the age of the larvae and the physiological condition at the different larval stages. As early as the first week the stress resistance of the larvae could be improved by feeding rotifers specifically enriched in DRA. However, the continuous feeding of these live preys did not result in the best larval output, indicating that... |

| The objective of the inoculation described in this paper was to test the feasibility of culturing <i>Artemia</i> in man-made earthen salterns and of producing adults and cysts for use in aquaculture projects in the Philippines. San Francisco Bay (California, USA) <i>Artemia</i> were inoculated in two concrete tanks and in four earthen ponds which are part of a small local salt factory. It was found that <i>Artemia</i> can be grown (with continuous production of nauplii and cysts) year-round in covered concrete tanks and in open concrete tanks and earthen ponds during the dry season (February to June). Lethal effects of too high water temperatures (>35°C) to the cultures were anticipated by the use of green coconut... |

| The mass-production of micro-algae has been recognized by several authors as the main bottle-neck for the culture of bivalve seed. This has prompted a search for alternatives to on-site algal production, such as dried heterotrophically-grown algae, preserved algal pastes, micro-encapsulated diets, and yeasts. However the extent to which these products have been tried, and rejected or retained by hatchery operators is poorly documented. Also, the actual algal requirement and production cost of the bivalve seed industry is difficult to estimate.The present inquiry allowed the collection of data concerning the requirement of live algae and its associated costs encountered in 50 commercial and experimental hatcheries from all over the world. Furthermore, the... |

| Because of their easy hatching from dry cysts and their year-round availability, nauplii of the brine shrimp <i><i>Artemia</i> salina</i> 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... |

| Biometrical, biochemical and food-value characteristics of <i>Artemia</i> nauplii vary with the source of the cyst material. In order to facilitate intercalibration and/or comparison of research conducted with cysts from different sources, homogenous cyst material can now be obtained from the <i>Artemia</i> Reference Center (State University of Ghent, J. Plateaustraat 22, B-9000 Ghent, Belgium). The reference cysts have been tested extensively for hatching characteristics, biometrics, fatty-acid content, pesticide contamination and effectiveness as larval food for various crustaceans and fishes. |
