Feeding larvae of pike-perch (Sander lucioperca Linnaeus, 1758) during their growing up in recirculating aquaculture system

The article presents materials on optimizing the conditions for growing pike-perch during larval period of development in an artificially created environment. problems associated with complexity embryonic and post-embryonic development, transition larvae from endogenous to exogenous food, their rearing artificial feed, causes cannibalism have been described. goal was obtain analyze results closed water supply using living organisms as starter feed. a study reproduction industrial aqua complex Coastal Scientific Expeditionary Base “Kagalnik” SSC RAS (Rostov Region, Azov District) are presented, describes recirculating aquaculture system. values main hydrochemical parameters environment fish tanks, necessary ensure normal growth larvae, well characteristics survival experiments, given. As result, biotechnical standards by intensive method developed. For high it is timely feeding – after filling swim bladder switching active feeding. diet should be varied terms species composition zooplankton. To prevent among farmed fish, important maintain at optimal level, presence food tank also necessary.
