Abstract EN
Understanding the reproductive biology of dominant coral species in subtropical nonreefal coral communities is critical in providing important information on the processes underlying the distribution limits of coral species and communities.
This is the first study that investigates the reproduction cycle, gametogenesis, and fertilization ecology of Platygyra acuta.
Results indicated that P.
acuta is hermaphroditic and exhibits a single annual gametogenic cycle.
Oogenic and spermatogenic cycle occurs for 6-7 months and for 2 months, respectively, prior to annual mass spawning event in May to June in Hong Kong.
It took 18 hours for P.
acuta to complete embryonic development, develop cilia, and start to rotate.
High (>70%) fertilization success can be achieved under a broad range of sperm concentrations from 104 to 107 sperms mL−1.
Fertilization success remained consistently high 6 h after spawning, indicating a prolonged viability of its gametes that is much longer than that recorded for other coral species.
Significantly higher percentage of fertilization success was recorded in the first of the two consecutive nights of spawning, suggesting differences in the quality of the eggs and/or sperms between days of spawning.
These results serve as important baseline information for better understanding of corals in marginal communities.
