Socioecological factors related to aquaculture introductions and production of Pacific oysters ( Crassostrea gigas) worldwide
Abstract Pacific oysters ( Crassostrea gigas ) have been introduced worldwide for aquaculture, which can benefit food sovereignty and economic development; however, established non‐native populations may present risks for local organisms and habitats. We reviewed the documented introductions of C. g...

Abstract Pacific oysters ( Crassostrea gigas ) have been introduced worldwide for aquaculture, which can benefit food sovereignty and economic development; however, established non‐native populations may present risks for local organisms and habitats.
