ABSTRACT: In Lake Ontario, five salmonid species are part of an economically important recreational fishery, with two native species undergoing bi-national restoration efforts. Understanding species distributions, movements, and habitat use can help management in maintaining a sustainable fishery as well as improve native species restoration. Thus, it is important to quantify the salmonid movements in relation to each other in Lake Ontario. Acoustic telemetry enables us to better understand the spatial habitat use of fish, particularly in large lakes where it is difficult to monitor. This endeavor is made possible through a large collaborative effort with academics and government on both sides of the border, unified by the Great Lakes Acoustic Telemetry Observation System (GLATOS). In 2017, 40 individuals across five salmonid species have been tagged in western Lake Ontario, with an additional 50 individuals tagged in 2018. With the ever-expanding receiver array in the western and eastern basins, we are beginning to see lake-wide individual movements of some species, including Chinook salmon (Oncorhynchus tshawytscha) and Atlantic salmon (Salmo salar). Overall, telemetry data is informative on various levels including describing cross lake and overwintering movements which represents a gap in our understanding of Great Lakes salmonid ecology.
