Pacific oysters crassostrea gigas (Thunberg) of possible French origin in natural spat in the British Isles
Abstract Hatchery‐reared Pacific oysters ( Crassostrea gigas ) grown in the British Isles and Guernsey originate from an introduction through quarantine of small numbers of oysters from British Columbia, Canada. Previous electrophoretic analysis of samples of these oysters have shown the glucose pho...
