Abstract

 The fish in farming systems are stocking in higher densities than in the nature. Proper stocking DENSITY has marked effect on the GROWTH of the fish. The purpose of this experiment was to determine the effect of different densities of RUTILUS FRISII KUTUM fry in eight weeks study on GROWTH. The experiment conducted on five densities (three replicate each) as following: 10 fish (0.174 kg/m3), 20 fish (0.348 kg/m3), 30 fish (0.522 kg/m3), 40 fish (0.696 kg/m3) and 50 fish (0.870 kg/m3) in 20 l water. Feeding rate was 10%, based on the total weight of the fish. The results showed that there was significant difference between the amount of body weight of the fingerlings in different treatments (P<0.05) so that the maximum weight and length was seen 30 fish/20 l (0.522 kg/m3) DENSITY. Also, there was a significant difference in FCR, SGR. BWI%, GR, CF and SURVIVAL rate between different treatments (P<0.05). The results of this study showed that the best stocking DENSITY for RUTILUS FRISII KUTUM fry is 350000/ hectare that may favorite optimum use of the pools for releasing the juveniles to the sea for restocking purposes.
