摘要

Local information on coral reproductive patterns is vital for coral reef conservation, rehabilitation, and restoration efforts. In the Philippines, data on the sexual reproductive strategies of broadcast spawning scleractinian coral species have slowly progressed. However, this information is mainly restricted to the country’s northern region. Here, we provided notes on the sexual reproduction of four Acropora species and one Favites species that were monitored and sampled from September 2015 to December 2016. The highest mean fecundities of polyps (mean ± SE) were variable for each species (Acropora cf. gemmifera: 14.3 ± 1.16, A. cf. sarmentosa: 8.35 ± 0.16, A. cf. valida: 11.2 ± 0.09, A. aff. tenuis: 23.7, Favites cf. abdita: 309.9 ± 33.94). The largest mean oocyte GMD for each species were variable. For Acropora spp., the values ranged from 425.28 to 539.16 μm, and is higher than F. cf. abdita (273.44 ± 2.85 μm). Although the in situ spawning was not observed for these aforementioned species, ex situ (laboratory) spawning was observed for A. cf. anthocercis colonies in October 2015 and October 2016, 11 nights after the full moon. The observations showed that the spawning duration in selected coral reef sites in the central Philippines are extended from April to December.
