Growing a triple hybrid of russian, siberian and amur sturgeons in a warm-water fish farm
Biological and production indices are presented for spawning females of triple hybrid between russian sturgeon, siberian sturgeon and amur sturgeon (RS × SS) × AS and other commercial forms of sturgeon grown in cages of the warm-water fish farm in Luchegorsk, Far East of Russia. In conditions of war...
