抄録

The effects of stocking density on the growth performance of Japanese conger Conger myriaster were investigated. Japanese conger (average body weight, 126 g) were reared in the 500L polyethylene tanks under the different stocking densities; 5, 10 and 15 kg/㎥ for 12 weeks with running water system. No significant effect of stocking density on the daily feeding rate, SGR, weight gain and feed efficiency were observed. These results indicate that the suitable stocking density of Japanese conger is more than 15 kg/m'.
