Physiological responses of the pectinate Venus clam, Gafrarium pectinatum (Bivalvia: Veneridae) to increasing turbidity concentrations

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
