Origin and route of establishment of the invasive Pacific oyster Crassostrea gigas in Scandinavia
Identifying the routes and rates of introductions is fundamental for the understanding of marine invasions. Recurring introductions over the last 50 yr have led to the establishment of feral Pacific oyster Crassostrea gigas populations throughout Europe. In the northern countries, Sweden and Norway,...

Identifying the routes and rates of introductions is fundamental for the understanding of marine invasions.
