Growth and sexual reproduction in the scleractinian coral <i>Montipora digitata</i> (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.
