The influence of thermal and hypoxia induced habitat compression on walleye (Sander vitreus) movements in a temperate lake by J. L. Brooks, E. J. I. Lédée, S. M. Larocque, S. J. Cooke, E. Brown, J. D. Midwood

“…Abstract Background Globally, temperate lakes are experiencing increases in surface water temperatures, extended periods of summer stratification, and decreases of both surface and deep water dissolved oxygen (DO). The distribution of fish is influenced by a variety of factors, but water temperature and dissolved oxygen are known to be particularly constraining such that with climate change, fish will likely feel the “squeeze” from above and below. …”
