Impact of an icy winter on the Pacific oyster (Crasostrea gigas Thunberg, 1793) population in Scandinavia
The Pacific oyster (Crassostrea gigas) is an invasive species that has dispersed into Scandinavia during the last few decades. The objective of this study was to evaluate the effects of extreme winter conditions on the mortality of the Pacific oyster in Scandinavia. The study was done by compiling m...
