Abstract

Reports of Pecten scallops in Geographe Bay in late 1975 were followed up by a preliminary stock survey in February 1976 using 1.22 m dredges and by a more extensive survey in September 1976 using 1.22 m and 2.25 m scallop dredges and a 0.5 m* Baird grab. Two very limited concentrations of scallops were located adjacent to rough ground. The best dredge catch rates were equivalent to 44 kg per hour per standard haul and the maximum grab catch was equivalent to a density of six scallops per square metre. The extremely rough terrain resulted in considerable damage to the dredges which indicated that the area is not favourable to dredging with existing gear.
