Study of muscl residue in Beluga(Huso huso) fed different dietary levels of aflatoxin B1.

In this study 180 beluga(Huso huso) weighted 120 ± 10gr with stocking density of 12 fish/tank ,after adaptation with synthetic diet , fed different levels of AFB1(0,25,50,75 & 100ppb/kg of diets) under controlled conditions(T=18±2ºC,DO=7.3ppm). The fish were fed 3% of body weight four times a day for 120 days.Record of physical and chemichal water caracters include : DO , temprature , pH , did weekly . Residue of AFB1 in muscls in different exprements determined by HPLC method . The amount of AFB1 in mscle was between 0.36 -2.90 ppb .Based on international standards these amount is not harmfull for human consumption.
