Assesses the economic and hygienic effects of aflatoxins in some of farmed fish and shrimp
Acipenser stellatus and Huso huso are the most important native sturgeon species in Caspian Sea. In the present study, the impacts of various concentrations of Aflatoxin B1 (AFB1) on Beluga, Huso huso, under controlled conditions were investigated. Belugas (120±10 g) were fed diets containing 0, 25,...
