An 8-week feeding trial was conducted to evaluate the effect of betafine on growth performance and survival rate on ship fry, Acipenser nudiventris. Betafin were added to commercial diet in four levels (0.5, 1, 3 and 5%) (Biomar) in circular tanks. Each diet was given to three replicate groups of fry ship (initially averaging 1.2±0.32gr). Based on the present results, enhanced growth performance, specific growth rate, feed conversion ratio and survival rate were generally observed in the fish fed with the diets supplemented with betafine 5%.
