Abstract :
The aim of this research is evaluation of different feeding frequency on growth parameters and survival rate of fingerling Cyprinus carpio fishes during 8 weeks. In this research 240 individual fishes with initial weight range of 8.85-9.26(gr) in 4 different treatments and 3 replicate such as T1 (once a day at 10h), T 2 (twice a day at 8 and 16 h), T 3 (thrice a day at 8, 12 and 16 h) and T 4 (four times a day at 8, 12, 16 and 20 h) were tested. Feeding rate was done according to 5 percent of body weight in a day. Results showed that, there are significant differences in increase of final fish body weight and final body length between different treatments (P<0.05). Although, highest body weight and body length increase in T 3 (thrice a day) was observed. Also, there were significant differences in different parameters such as FCR, SGR, BWI, PBWI, FI, CF, GR and production parameters between different treatments (P<0.05). However, there was no significant differences in survival rate of different treatments observed (P>0.05). Finally, 3 times feeding frequency in a day (T 3) according to growth performance of different treatments for common carp fingerling fish was suggested.
