Title

THE EFFECT OF DIETS SUPPLEMENTED WITH DAPHNIA AND NEREIS POWDER ON THE SURVIVAL RATE AND SOME GROWTH FACTORS IN ACIPENSER PERSICUS

Pages

  27-36

Abstract

 This study was conducted in order to characterize the effects of different diets on survival and some GROWTH FACTORS of ACIPENSER PERSICUS in the International Sturgeon Research Institute in 2010. Thirty tanks were prepared and filled with water. Also, 60 larvae were selected randomly and their weight and length were measured and then were transferred to mentioned tanks. Ten diets containing different amounts of usual concentrated feed, DAPHNIA POWDER and NEREIS POWDER were prepared as experimental diets. Five days after active feeding, in order to adaptation with larvae digestive system, feeding with special diets was continued. Ten days after active feeding, larvae were fed 30% of their wet weight with experimental diets for 35 days. Physico-chemical parameters of water were measured carefully twice a day. At the end of experiment, the weight and the length of larvae were measured and survival rate and some GROWTH FACTORS such as FCR, SGR, BWI and GR were calculated. The results showed that larvae fed diet 3 (100% NEREIS POWDER) and diet 4 (50% DAPHNIA POWDER and 50% NEREIS POWDER) had the highest survival rate, SGR, BWI and GR compared to other treatments (p<0.05). On the other hand, these two treatments (3 and 4) along with treatments 1 and 5 have the lowest FCR compared to other treatments (p<0.05). The lowest survival rate, SGR, BWI and GR was observed in fish fed diets containing 100% concentrated feed (p<0.05). The results of the present study showed that using NEREIS POWDER lonely or in combination with DAPHNIA POWDER comparing to concentrated feed may have beneficial effects on survival and growth of ACIPENSER PERSICUS.
