| Research Abstract |
We analyzed the breeding records of reef fishes up to the present to estimate the impact of global warming on the reproductive ecology of these fishes. The breeding behavior of 23 species of damselfish (Pomacentridae), belonging to seven genera was observed off the Hachijojima Island. The breeding season in many species was from spring to autumn, although some species were found to breed after autumn or throughout the year. Our results suggested that water temperature is not always a factor that has most decisive influence for breeding.
