A total of 221 fish species comprising 47 families were caught and identified using a beach seine in the two seagrass stations of Samal and Talikud Islands, Davao del Norte, Philippines monitored monthly in both diel periods (day and night time) from March 1998 to April 1999. The survey was topped by a scribbled rabbitfish Siganus spinus (Family Siganidae), an economically important fish caught abundantly during daytime. Most of the physicochemical parameters were found to be insignificantly correlated to the total ichtyofauna in the two seagrass stations using Person Correlation Analysis. The total abundance and biomass data using t-test showed that there was no significant difference between the two stations but in each station, day and night catches differ significantly. Species diversity and species richness also differ significantly between the two stations and in each station between day and night time using ANOVA test.
