Ichthyoplankton samples from 20 reef stations were collected in Southern Guimaras, Central Philippines, during the day and night by means of 5 minute surface horizontal tows using a rectangular plankton net with a 300μm mesh bag attached to it. Overall mean ichthyoplankton density at night (168ind/100m^3) was three times more than that during the day (56ind/100m^3), while taxon richness (family level) was 50% higher at night. These results are compared with observed diel patterns in other investigations. Diel differences in overall egg and larval densities and composition are related to the station location, substrate and other factors. The relative similarity in day-night patterns in stations over deep water suggests that the substrates (seagrass beds and coral reefs) serve as shelters from predation during the daytime.
