The eggs were hatched at 11,62±0,56 °C water temperature and hatched alevins were placed in an aquarium about 500 individual. The alevins 21th day were divided two groups as A and B and A group was fed three times daily. When 90% hatching of the eggs were accepted 0 (zero) and alevins were sampled in 7th, 14th, 21th, 28th, 35th, 42th, 49th days. The dry yolk sac weight of A and B groups for both were calculated as 23.01±0.76 mg hatching and 0.72±0.27 mg and 0.70±0.29 mg swim-up stage (p<0.05). Regression analysis of A and B groups with length, wet alevin weight, dry alevin weight, total wet <br />weight (wet alevin weight + wet yolk sac weight), total dry weight (dry larvae weight + dry yolk sac weight) differences were significantly (P<0.05), while dry and wet yolk sac weights differences were insignificant (P>0.05). The highest yolk sac conversion efficiency, weight and length growth rates, yolk sac absorption and condition factor values were calculated in A group (P>0.05). <br /> </p>}, number={1}, publisher={Kastamonu Üniversitesi}
