The aim of the study was to determine the effect of Biotox on growth performance, survival, enzymatic activity, hematological and biochemical parameters of fingerlings rainbow trout fed with aflatoxin. For this purpose, 900 fish were stocked in four treatments at the pools and fed 4 times a day by supplementing the basal diet with 0.1% Biotoxin+1 mg/kg aflatoxin (T1), 0.2% Biotoxin+1 mg/kg aflatoxin (T2), 1 mg/kg aflatoxin (T3) and basal diet as control group (T4) for 60 days. There were significant differences (P<0.05) in survival in fish fed different diets for 60 days. Survival was higher in the T2. there were no significant difference (P>0.05) was observed in growth performance, activity Alkaline Phosphatase (ALP) and hematological parameters, of fish in different treatments. Also, no significant difference (P> 0.05) in serum globulin, albumin and total protein was observed between treatments and control group. The results of the present study showed a significant (P<0.05) increase in Glucose and triglyceride in T3, whereas serum cholesterol was higher in T3 and control group. Addition of 1-2 g Biotox/ kg feed did not affected growth performance and hematological parameters, but increased survival of fingerling fed with the diets of aflatoxin B1-exposed.
