Effects of fish herbivory on seagrass meadows of Guang-guang, Mati City, Philippines

This study provides information on the effects of fish grazing a seagrass bed that was dominated by Thalassia hemprichii in Guang-guang, Dahican, Mati City, Davao Oriental, Philippines. We tested assumption herbivore exclusion keeps growth shoots up to minimum length. Fish visual census used count abundance area during high tide at distance 5 m away from treatment cages with 15 transect Among all species, Siganus fuscescens most abundant (499) followed S. guttatus (153), while Thalassoma jansenii less (13). The result weekly showed highly significant variations number and species present (df = 11, MS 2.88, F 30.10, p < 0.001). Analysis shoot length measurement also exhibited differences throughout sampling period 726.71, 1,633.10, Comparison between initial final counts differences, higher full cage (X2 8, df 2, 0.018; FC > PC OP). raises clear evidence support positively influences T. this area.
