Growth performance, feed utilization, survival and
body composition of rabbitfish Siganus canaliculatus
raised at two different stocking densities in sea net cages
Over a period of 213-day, the effect of two stocking densities (8 and 12 fish/m3)
on the performance of the rabbitfish, Siganus canaliculatus (3.38g ±0.14) in floating cage
nets was tested. The results of the study revealed no differences (p < 0.05) in the growth
performance and survival of the two groups. Comparatively, the fish group under the higher
stocking density (12 fish/m3) exhibited a lower survival rate. The values of feed intake, feed
utilization efficiency and final body composition for both treatments did not differ
significantly (p < 0.05). In conclusion, the study suggested the possibility of applying higher
stocking density in commercial rabbitfish farming. However, more studies are needed on
the effects of high stocking densities on fish survival
