Fish distribution, movement and gross external pathology information for the Peace, Athabasca and Slave River basins / prepared for the Northern River Basins Study under project 5324-E1 by T.A. Mill, P....: R71-49/3-147E-PDF

"The composition of the fish community and its seasonal use of aquatic habitats for spawning, growth, overwintering and feeding can be important indicators for assessing the health of the Peace, Athabasca and Slave rivers aquatic ecosystem. The extent to which these uses are affected by existing development is a major area of interest for the Northern River Basins Study (NRBS). One of the objectives of NRBS was to gather together existing information on fish to assist in the evaluation of effects from development. Investigations of fish population dynamics was beyond the scope of the Study. However, emphasis was directed at gathering more information on fish distribution, movement and habitat utilization. As a consequence of these investigations, supplemental material was gathered including information on the incidence of fish abnormalities. This report presents the findings of the various field and laboratory projects as they relate to fish distribution, movement, habitat utilization and gross pathology"--Study perspective.
