Assessing the distribution and abundance of both predator and prey (forage) fish species is a cornerstone of ecosystem-based fishery management, and supports decision making that considers food-web interactions. In support of binational Great Lakes fishery management the objectives of this survey were to: provide estimates of densities of key forage and predator species in the western basin of Lake Erie, to assess seasonal and spatial distributions of fishes in tandem with water quality information, and to assess year class strength. A systematic grid sampling approach with 41 stations was sampled via bottom trawl during June (Spring) and September (Autumn), starting in 2013. This data release adds 2021 data to...

While recording fish habitat use via electronic sensors, biologgers can also be viewed as autonomous environmental monitoring systems with the organism as a vehicle. This dual perspective has provided novel results from marine ecosystems but has not been applied to freshwater ecosystems. To understand limitations in freshwater, we evaluated miniature depth and temperature recorders, as aquatic monitoring systems in Lake Erie. As part of an acoustic telemetry study, biologgers were implanted in a subsample of walleye, Sander vitreus in 2014. Biologgers were equipped with sensors capable of measuring water temperature and depth at half-hour intervals for up to a year. Recaptures provided six biologgers for analysis...
