Abstract
Specimens for the study on coral spawning of three
species were collected at two sites in Nha Trang bay, South Viet Nam, in 2014, 2015, 2016, 2018 and 2019. The determination of
spawning seasons was based on observations of gonadogenesis development of A.
florida and A. robusta and variation of egg average sizes of these two species
and A. hyacinthus. Data analysis and comparative discussions allow us to assume
that the 3 Acropora species exhibited single cycle spawning annually and their
spawning period occurred in March/April between the full moon and crescent
moon. However, their maturity periods were not the same, starting before and
ending after the full moon for A. florida and A. robusta but starting after the
full moon and lasting until the crescent moon for A. hyainthus. Further studies
are needed to improve the understanding of coral spawning and support coral
restoration using sexual reproduction.
