Introduction, establishment and expansion of the Pacific oyster in the Oosterschelde (SW Netherlands)
International audience The Pacific oyster was first introduced as an exotic species by oyster farmers in 1964 in the Oosterschelde estuary (SW Netherlands). The initial phase is not well documented but first natural spatfall was recorded in 1975. Excessive spatfall occurred in 1976 and this is consi...
