Growth and sexual reproduction in the scleractinian coral Montipora digitata (Dana)

Abstract

Colony growth rate and sexual reproduction in M. digitata were quantified. Growth rate was expressed in terms of branch linear extension, with a maximum rate of 30.5 mm year^-1 for the population. Gametogenesis and spawning were recorded for the first time. M. digitata has an annual gametogenic cycle followed by a brief spawning event where gametes are shed into the water before external fertilization and embryogenesis.
