Abstract
Purpose. To review scientific sources on the morphological and ecophysiological peculiarities of the transition of early sturgeon fry (Acipenseridae) to artificial formulated feeds. To summarize the biotechnological fundamentals of the use of artificial formulated feeds in the conditions of recirculating aquaculture systems (RAS). Findings. The transition of early sturgeon fry to artificial formulated feeds is one of the most difficult stages of their rearing, even under controlled conditions of RAS. The review contains the description of the peculiarities of sturgeon embryogenesis, their behavior and morpho-physiological changes at this stage of their development. It contains main requirements for the rearing of sturgeon larvae in RAS. We showed that the ultimate refuse from natural (live or frozen) forage organisms is not advisable; the optimum is their combination with artificial feeds with gradual predominance of the latters. We provided the schemes of their feeding based on the combination of natural and artificial feeds. We reviewed the most common biologically active supplements, which contributed to better feed digestion during the periods of the transition to exogenous feeding. We highlighted the effect of feeding with brine shrimp nauplii enriched with polyunsaturated fatty acids on the growth and development of early sturgeon fry. Practical value. The array of the summarized information will be important for scientists who study the peculiarities of the transition of early sturgeon fry to artificial formulated feeds in RAS. The data on the biotechnologies of rational feeding of early sturgeon fry in RAS in this period are important in the conditions of continuous search for the most effective replacement of live forage organisms and reduction of fish fry mortality in postembryogenesis.
