Abstract: This study is a first step in evaluating the potential of the filter-feeding clam Gafrarium pectinatum as an aquaculture species in northern Philippines. Effect of increasing turbidity concentrations on the filtration and pseudofaeces production of small-sized (25.52 ±1.24 mm shell length) and large-sized (36.36 ±1.42 mm shell length) clams were quantified under laboratory conditions. Filtration rates and pseudofaeces production significantly increased (p<0.05) with increasing turbidity concentrations. Shell size was not a factor that influenced the feeding physiology of the clams. Strong linear relationship (r2=0.71) was observed between the filtration rate and pseudofaeces production of G. pectinatum. The result of the study showed the G. pectinatum is a sturdy bivalve and could be a potential species for aquaculture.
