Monthly biomass (g dwt m-2) of Gracilaria changii, G. manilaensis and Gracilariopsis bailinae collected in four different coastal areas of Iloilo, Philippines showed significant differences. Gracilaria changii (3.0-32.4 gm-2) and G. manilaensis (8.9-35.7 gm-2) were present only for six and three months respectively during the dry season. Gracilariopsis bailinae was present year-round at both sites, however, its abundance was not uniform, being abundant during the wet season in Estancia (13.4-119.3 gm-2) and during the dry season in Zarraga (6.9-43.5 gm-2). Except for rainfall and level of phosphate, all environmental factors (temperature, salinity, pH, turbidity, NO2-N and NH2-N) showed insignificant relationship with the biomass of each species.
