Effects of dietary alpha-linolenic acids on growth performance, lipid metabolism and antioxidant responses of juvenile Russian sturgeonAcipenser gueldenstaedtii

Five isonitrogenous diets were formulated with graded alpha-linolenic acid (LNA) levels (0, 5, 10, 15 and 20 g/kg) to investigate LNA requirement of juvenile Russian sturgeon Acipenser gueldenstaedtii.
