| The effect of dietary purified phosphatidylcholine (PC) was evaluated on growth, survival, resistance to osmotic shock, and fatty acid composition of early postlarval <i>Penaeus vannamei</i> (0.3 mg initial dry weight) fed semi-purified diets. PC sources used were purified soybean PC (SPC, 95% purity), chicken-egg PC (ECP, 94% purity), and de-oiled soybean lecithin (DSL, 23% PC). The growth response of shrimp fed 1.5% of SPC or 6.5% of DSL was significantly greater than that of shrimp fed a PC-deficient diet, whereas no effect was observed either on survival or stress resistance. Further increasing the dietary level of soybean PC from 1.5% to 3.3% resulted in a significant decrease of the shrimp weight gain. Shrimp receiving 1.5% of PC,... |

| Variations in dry weight, caloric content and ash content during cyst hatching and early larval development have been studied for various geographical strains of <i>Artemia</i> . In general, decapsulated cysts contain 30 to 40% more energy than freshly hatched nauplii; for Chaplin Lake and Buenos Aires <i>Artemia</i> 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... |

| As described in our previous paper (Sorgeloos et al. , 1977) hypochlorite can be used as reactive agent to dissolve the lipoproteic chorion of <i>Artemia</i> cysts. Two commercial products are available worldwide, i.e. bleaching powder, chloride of lime Ca(OCL)<sub>2</sub> 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. |

| <i>Artemia</i> 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 <i>Artemia</i> 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... |

| This paper describes the first results of a study on the effects of broodstock nutrition on reproduction in marine crustaceans. For this, a short-term test system has been developed with the estuarine mysid shrimp <i>Mysidopsis bahia</i> (M.) as experimental animal. Three different <i>Artemia</i> preparations were evaluated for their possible effects on reproductive activity and offspring quality: a commercial maturation diet (Marila) incorporated in Great Salt Lake <i>Artemia</i> metanauplii was compared to freshly-hatched nauplii and coconut-oil enriched metanauplii as food sources for the experimental broodstock animals. Within an experimental period of 14 days after reaching sexual maturity, 3.4 respectively 8.8... |

| The recent developments in aquaculture production of fish and shrimp have resulted in increased demands for <i>Artemia</i> cysts and biomass as valuable sources of life food. Solar salt works are suitable biotopes for the integrated exploitation of salt, <i>Artemia</i> and eventually fish or shrimp. <i>Artemia</i> 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 <i>Artemia</i> species to increase productivity. |

| In order to prevent any further confusion in the scientific literature, we would like to urge contributors to ensure that the citation of <i>Artemia</i> in scientific articles in <i>Aquaculture Research</i> is taxonomically correct. Too frequently, reference is made to <i>Artemia salina</i>. This binomial refers to a European species which may be extinct. Most scientific studies are, however, based on the New World species <i>Artemia franciscana</i>. We estimate that over 90% of the studies in which <i>Artemia</i> 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. Today at least six bisexual... |

| Different species of microalgae, the rotifer, <i>Brachionus</i> spp., and the brine shrimp, <i>Artemia</i> spp., are essential live food in the farming of several species of molluscs (e.g. oyster, clam, scallop), crustaceans (e.g. marine shrimp, freshwater prawn, crabs) and fish (e.g. bass, bream, grouper, turbot, flounder, halibut, ayu). A brief overview is given of the latest developments in their production and use in industrial hatcheries. |

| Freshly-hatched <i>Artemia</i> nauplii from various geographical sources survived storage in a refrigerator (2-4°C) at densities of 2000 per ml and above. Except for <i>Artemia</i> 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 <i>Mysidopsis bahia</i> M. and larval carp <i>Cyprinus carpio</i> L. revealed similar production performances. |

| Technological problems can be considered as one of the bottlenecks of research concerned with culturing aquatic invertebrates in the laboratory, as well as the pilot and mass production stages. Oxygenation problems, circulation of the food and sedimentation problems can easily be solved by adapting the shape of the culturing vessels, i. e., by using funnel-shaped bottoms or high, narrow cylinders. In both cases, the food particles, settled on a very small bottle area, can easily be blown back into suspension using an air pump, which re-aerates the medium at the same time. A number of culturing devices for different categories of organisms, including algae are described and commented on. The only power source involved is compressed air which aerates, keeps... |
