Research Abstract |
The effectiveness of the long-afterglow phosphorescent pigment (LumiNova) on the reproductive performance of the sapphire devil Chrysiptera cyanea was examined. When the fishwere reared in aquaria covered with LumiNova sheets under natural photoperiod and temperature during the breeding season, they maintained high gonadal activity. Rearing the fish with a LumiNova pellet on their head under a programed light-dark cycle during the non-breeding season resulted in induction of gonadal development. Because LumiNova continues to emit green light during dark phase, the extended light conditions probably contributed to active reproduction in the fish. In conclusion, long-afterglow phosphorescent pigment can be used for energy-efficient aquaculture to regulate the reproduction of fish.
