Determining when corals reproduce has clear management and economic implications. Here we document the reproductive condition of corals in the genus on the island of Socotra in Yemen during February 2014.Acropora Twenty percent of colonies (n = 143) contained mature gametes and 28 % had immature gametes indicating that spawning will occur in both February and March in 2014, confirming previous anecdotal reports of coral spawning at this time in Socotra. typically reproduce in synchrony with many otherAcropora broadcast spawning scleractinian corals, and we therefore predict that many other species are reproductively active at this time of year
