Growing sturgeon juveniles using compound feed enriched with artemia extract

In modern conditions, fish farms focused on commercial fish farming are actively looking for ways to increase the efficiency of using compound feed to improve product quality. Along with optimizing conditions, using highly productive feed and selective breeds, more and more attention is paid to feed additives, which at a relatively low cost can significantly increase production profitability. This study is aimed at assessing the effectiveness of one of the little-studied, but promising additives — alcohol extract from Artemia (Artemia salina, Linnaeus 1758). Although the Artemia crustacean itself is well known in aquaculture as a valuable feed object, its alcohol extract has not yet become widespread due to insufficient study and the lack of public studies. At the same time, some manufacturers already include it in the composition of compound feeds at the production stage. It is important to note that the traditional use of Artemia has a number of disadvantages: the complexity of incubation of nauplii, limited shelf life, inaccurate dosage and, as a result, difficulties in assessing its beneficial properties. It is expected that the alcohol extract will minimize these problems without a significant loss in productivity compared to the live form of the crustacean.
