Reproductive behavior and color pattern in a fresh water serranid fish coreoperca kawamebari

Reproductive behavior and color pattern in a fresh water serranid fish coreoperca kawamebari

The behavior and color pattern of the freshwater serranid fish, C. kawamebari, were observed during the breeding season in aquaria simulating natural habitat. The male was very aggressive and territorial during this season, permitting only spawning-ready females to enter his territory so he could court them. The male courtship consisted of aggressive and other certain activities appearing exclusively during the breeding season. The male displayed an intermediate color over his entire body with conspicuous eye-like spots and as this pattern is the same as the aggressive pattern, the internal breeding system seems to control the male color pattern indirectly through activating the aggressive system. Female courtship contained both fear and courtship-characteristic components. The female showed a dark color over her entire body with a white vertex band only during courtship encounters and the white vertex band is the same component appearing in the fear-motivated pattern. The female color pattern is subject to both internal fear and breeding systems.
