抄録

Effects of different light intensities (20, 200 and 1000 lx) and colors (green, white, red and black) of the rearing tank on cannibalism in the juvenile orange-spotted grouper (Epinephelus coioides) were investigated. Mortality at the high light intensity (1000 lx) was significantly higher than the control group (200 lx). In the red tank group, mortality was significantly lower than that in the green tank counterpart (control color). The body color at the end of experiment was light brown for the control and white tank groups, whereas body colors for the black and red tank groups were black and dark brown, respectively. These results suggest that light intensity and color of the rearing tank affect the occurrence on cannibalism in the juvenile orange-spotted grouper.
