The effect of refuge on mortality by cannibalism in the juvenile orange-spotted grouper <I>Epinephelus coioides</I> was investigated in rearing conditions with or without artificial refuge (an air stone or pipes) for 10 days. In TL 26 mm juveniles, there was no effect of refuges on mortality by cannibalism. However, in TL 30 mm juveniles, mortality by cannibalism significantly reduced in fish reared without refuge. These fish (>30 mm TL) have a trait of gathering around the refuges. In these cases, the artificial refuge enhances the occurrence of cannibalism in the juvenile orange-spotted grouper.
