These data were collected from sampling efforts in November 2017 and October-November 2019. Stony Island Reef is a cobble spawning reef located in the eastern basin of Lake Ontario and was chosen as the study site because it was identified previously as an important spawning area for the extirpated native Lake Trout stock and was the focus of earlier Lake Trout reproduction studies.
