Effects of lecithin on growth and hematological indices in juveniles of Siberian sturgeon (Acipenser baeri Brandet 1869)
This study was carried out to evaluate the effects of dietary lecithin on growth performance and hematological indices in juveniles of Siberian sturgeon (Acipenser baeri). Fish with initial average weight of 32.9±0.3 grams were fed five isoproteic and isolipidic formulated diets with different soybe...
