Behavioural Interactions Between Coho Salmon 'Oncorhynchus kisutch', Atlantic Salmon 'Salmo salar', Brook Trout 'Salvelinus fontinalis' and Steelhead Trout 'Salmo gairdneri', at the Juvenile Fluviatile Stages

摘要

Behavioral interactions were studied, in a stream tank, between coho salmon (Oncorhynchus kisutch), brook trout (Salvelinus fontinalis) and Atlantic salmon (Salmo salar) and between steelhead trout (Salmo gairdneri), Atlantic salmon and brook trout. Steelhead trout and Atlantic salmon were the most aggressive species. In all experiments the dominant species showed the best growth.
