sealord > Scallop fisherman Stan Breban caught this fan mussel, Atrina fragilis, while dredging for scallops on the 30 January 2007. The shell length was 23.0 cm. The maximum shell width was 12.83 cm (measured with callipers) and the maximum thickness of both valves of the living animal was 5.04 cm. The bivalve drained of free water weighed 293 grams. The fan mussel was caught in 54 fathoms of water somewhere south-east of Sark to the east of the Longue Bank. Stan told me he sees about four of these fan mussels per year. The live Atrina fragilis was returned to a net bag under the pontoon by the fish quay in St. Peter Port harbour after photography. Later Stan returned the live bivalve mollusc to the open sea.
