Özet

This study was conducted to examine the effects of feeding diets, different dose of vitamin E contains, on female and male Black Sea trout's (Salmo labrax) reproductive performance. Broodfish were fed with dry feed contained 100 (control), 250, 500, 1000 mg kg(-1) vitamin E. Milt volume, spermatozoid number, fecundity and egg size were determined. Milt volume and sperm number were positively affected at a dose of 250 and 500 mg kg(-1) vitamin E in the diet. A similar positive trend was also observed at the dose of 1000 mg kg(-1). Egg size is not affected by dietary vitamin E dose, but there are positive relationship between total fecundity and dietary vitamin E dose especially at the first stripping (P<0.05).
