Macroalgae in the intertidal rocky shore of Iligan Bay

Rocky shores are commonly found in the coastal areas of Iligan Bay and mostly colonized by a great variety of macroalgae. Due to limited data, the diversity and abundance of macroalgae were investigated in eight sampling sites of Iligan Bay using the transect-quadrat method. A total of thirty-seven (37) species were identified including 17 green, 9 brown and 11 red algae, identified at eight sampling sites. Result showed that the seaweed biomass was highest in Buru-un and the major bulk of its dry weight materials were composed of Ulva reticulata. Moreover, Jampason had high species diversity because of its high species richness.
