| A flow-through culture system is described for the controlled production of <i>Artemia</i> cysts in 10 liter aquaria using 50 promille artificial seawater enriched with Fe-EDTA as culture medium, micronised rice bran as food source and cyclic flushes of the cultures with N<sub>2</sub>-gas as induction mechanism for oviparity. The culture water is recirculated over a rotating biological contactor, a settling tank and a UV disinfection unit. Cysts are continuously harvested by filtration of the culture effluent. Production yields average 0.5 g dry cysts per day and per aquarium. |

| The effect of bacterial strains on the growth rate of rotifers, Brachionus plicatilis, was determined under monoxenic conditions. The first objective was to obtain sterile rotifer cultures starting from rotifer resting eggs using merthiolate or glutaraldehyde as disinfectant. Sterile rotifer cultures were obtained, without affecting the hatching ability of the resting eggs, when 0.05 µl/l glutaraldehyde was used. This disinfection procedure was used to examine the effect of 20 bacterial strains, isolated from well-performing live-feed production systems, on the population growth rate of rotifers cultured under monoxenic conditions. Five out of the 20 bacterial strains tested were able to improve significantly the asexual reproduction of rotifers. The... |

| The brine shrimp <i>Artemia</i> , an excellent live food source in aquaculture, has been studied as a carrier to deliver selected chemotherapeutic agents to fish for prophylactic treatment of infectious diseases. To monitor the efficiency of incorporation of trimethoprim and sulfamethoxazole in <i><i>Artemia</i> franciscana</i>, a sensitive and specific analytical method was developed. It is based on homogenization of <i>Artemia</i> nauplii in methanol, extraction of lipids with hexane, solid-phase cleanup on C<sub>18</sub> cartridges, and reversed-phase liquid chromatography with detection at 210 nm. The method is sensitive (detection limit, on the order of 3 µg/g with a sample quantity of 30 mg... |

| The possible benefits of feeding a formulated diet, together with <i>Artemia</i> , to first-feeding turbot larvae were investigated. Five dietary regimes were used: control ( <i>Artemia</i> 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 <i>Artemia</i> 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... |

| Starting with the major issues of the recent World Conference on Aquaculture, organized in 1981 jointly by the European Mariculture Society and the World Mariculture Society, the paper indicates a number of new and appealing maricultural technologies in shellfish and fish farming. It is postulated that several of the techniques described will have a far-reaching impact on maricultural production in the next decade. Special attention is given to the potential of the mass production of brine shrimp <i>Artemia</i> in extensive and intensive operations, and in particular to its key role in vertically integrated aquaculture. |

| Automatization in the food distribution is necessary for the controlled culturing of filter feeders in high densities. Numerous devices have been described to distribute specific quantities of food suspension at preset time intervals (cf. review in Kinne, 1977). The number of systems which, however, add food whenever a preset critical turbidity of the medium is exceeded are rather limited. They furthermore are either very expensive (sophisticated equipment) or have to be cleaned very often (cf. review in Sorgeloos et al., 1976). We tried to simplify the technological complexity of the existing systems and developed an inexpensive, automatic, self cleaning food distributor. This apparatus measures the turbidity of the culturing medium which is pumped into a... |
