Project Description
Bloater (Coregonus hoyi), a deep-water cisco extirpated from Lake Ontario in the early 1980s, has been stocked annually with the aim of re-establishing the species and diversifying the prey base. To better understand mortality due to predation and potentially barotrauma, acoustically tagged juvenile bloater are stocked over three depths (5, 55, 100 m) in the Eastern basin of Lake Ontario. Behaviour and habitat use will be quantified across these depths over short (days) and longer (weeks/months) time periods. A better understanding of movement and mortality of stocked fish will aid in refining stocking strategies and inform restoration potential for the species.
