A brief survey of the Russian literature of the production of live preys for feeding young sturgeons is presented. These preys are plankton organisms (Moina, Daphnia, Artemia), chironomids and oligochaets cultured in large scales mostly in state hatcheries to produce sturgeon juveniles for stocking. Thus those culture systems operate only for a short period of time. In general, an innoculum of broodstock material is introduced into the tank or the pond in which the preys are cultivated. Various feeds and fertilisers are distributed. Daily production is 10 g/m2 for chironomids and 55 g/m2 for oligochaets. For daphnia, under optimum condition of temperature and water quality the production is 20 to 35 g/m3 for the whole season. Such productions are high but the systems operate only during few months corresponding to the short rearing period of sturgeon, at least in the case of stocking. In indoor condition the plankton is distributed to the sturgeons in the rearing tank. One way is to keep constant the plankton concentration (5 mg plankton wet weight per 1 m3 of water). Associations of preys are also given; for instance zooplankton and oligochaets distributed in % of the fish biomass: 20% the first 20 days and 15% from days 30 to 40.
