An update on modes and timing of gamete and planula release in Hawaiian scleractinian corals with implications for conservation and management

Abstract

Reproductive data for 24 of the 50 plus species of scleractinian corals in Hawai'i are available. A majority of species (75%) are broadcast spawners, just over half (58%) of which are hermaphrodites. Peak reproduction of Hawaiian corals occurs during summer months, although reproduction continues year-round for some brooders. Timing, duration, mode, and location of reproductive processes have implications for disturbance management, assessment, and conservation of reef corals.
