Effects of different stocking densities on the growth and food conversion ratio of Japanese eels (Anguilla japonica T. et S.) and on the water quality in still-water conditions

Effects of different stocking densities on the growth and food conversion ratio of Japanese eels (Anguilla japonica T. et S.) and on the water quality in still-water conditions

Doga Bilim Dergisi, D1 Veterinerlik ve Hayvanclk 9(1): 77-88

The liveweight gain and food conversion of Japanese eels were highest at a stocking density of 0.25 kg/msuperscript 2 and decreased steadily with increase of stocking density. Food conversion ratios varied from 1.23 to 2.22 among the groups. Condition at 0.25 kg/msuperscript 2 was higher than in other groups, while there was no significant difference among the other stocking densities tested. The amount of dissolved oxygen decreased as stocking density increased.
