Acoustic telemetry in Toronto Harbour : assessing residency, habitat selection, and within-harbour movements of fishes over a five-year period / by Jonathan D. Midwood, Andrew M. Rous, Susan E. Doka, and... : Fs97-6/3331E-PDF
"The Toronto and Region Area of Concern (AOC) has a long history of development that has resulted in substantial losses of fish habitat. Efforts are ongoing to create new habitat and remediate degraded habitat in the AOC. This report presents high-level results from a five year acoustic telemetry study of fish movements and habitat selection in the AOC. Given the documented reliance of many of the tracked fishes on warmwater habitat, results highlight the importance of protecting and (where possible) expanding warmwater habitat in the system. Results from an assessment of fish residency within the central waterfront of the AOC characterize different species as primarily resident (i.e., Largemouth Bass [Micropterus salmoides]; Northern Pike [Esox lucius]) or migratory (i.e., Common Carp [Cyprinus carpio]; Walleye [Sander vitreus]; White Sucker [Catostomus commersonii]), which can inform both the recovery of target species (i.e., Walleye) and assessments of contaminant burden in fishes captured in the AOC (i.e., Common Carp and White Sucker). Finally, a major product from this report is the development of a data processing and analytical approach that can review, integrate, and summarize extensive acoustic telemetry datasets to support more targeted analyses of fish habitat use. Future efforts will focus on more detailed species- or site-level analysis to provide a better understanding of their core ecology and aid in the development of species-specific habitat remediation strategies not only for the Toronto and Region AOC, but also throughout the Great Lakes"--Abstract, page xix.
