Observations document reproductive patterns in three coral species in Zanzibar, suggesting vital insights for conservation efforts.
Key Points
The study aims to document the spawning timing and behaviour of three coral species in Zanzibar, contributing to understanding their reproductive health.
Conducted in situ observations during monthly nighttime monitoring dives.
Focused on three species: Galaxea astreata, Favites pentagona, and Platygyra daedalea.
Timed observations with lunar and solar cycles linked to spawning events.
G. astreata spawned on the second night after the full moon in November and December.
F. pentagona spawned on the fourth night after the full moon in November.
P. daedalea spawned on the fourth night in December and January.
Spawning behaviour varied among species, including gamete setting and release windows.
