| Introduction of new species to aquaculture systems by creating species diversity in fish culture and reproduction ، obtaining more production per unit area of farms and increase in income also it can lead to diversify the food basket of families. The aim of this study was the Investigation of growth and feasibility culture of Capoeta capoeta gracilis by using different feeding rates in laboratory conditions. So the effect of feeding ration on increasing body weight, food conversion ratio, specific growth rate, daily growth and condition factor were studied. This research designed in completely random design with 3 treatments and 3 replications on C. c. gracilis that have average weight 18-16 g and a length of 13-12 cm that were fed according to 2, 4, and 5% of body weight for 60 days. The results showed that body weight increasing, percentage of body weight increasing, specific growth rate and condition factor in treatments of fish fed with 4% of body weight was more than other treatments. Feed conversion ratio also in the treatment of fish fed with 4% of body weight was less than other treatments and there was no significant difference between treatment fish fed with 5% and 4%of body weight (p>0/05). According to these results and better growth of C. c. gracilis fed with 4% of body weight, it is possible that the C. c. gracilis can be introduced to culture farms. |
