RESEARCH REGARDING THE EVOLUTION OF CORPORAL WEIGHTES AND FOOD CONVERSSION ON JUVENILE OF SIBERIAN STURGEON (Acipenser baeri) RAISED IN RECIRCULATING SYSTEM
The research was performed within the recirculating aquaculture system for sturgeon growth, in Banat's Universsity of Agricultural Sciences and Veterinary Medicine from Timisoara, on 2851 juveniles of Siberian sturgeons (Acipenser baeri), aged between 132-175 days. Juveniles were maintained in...
