Movements and temperatures of radio tagged salmonines in Lake Ontario and comparisons with other large aquatic ecosystems.

Abstract

We used six years of radiotelemetry data (1980-86) to compare movements and temperatures occupied by four introduced salmonine species (174 tagged fish) in the nearshore region of Lake Ontario. Movement patterns, net movement rates, water temperatures occupied, and harvest rates by anglers were generally similar among species and seasons. The movement patterns and thermal habitats of salmonines in Lake Ontario generally were in the mid-range of those report for conspecifics in other large lakes and the North Pacific Ocean.
