STATUS OF MAJOR SPECIES
The following is an overview of the status of major species in Ontario waters of Lake Erie for 2015. International lake-wide perspectives are available in the following reports of the Lake Erie Committee (LEC) of the Great Lakes Fishery Commission:
Walleye Task Group Report

The lake-wide commercial Walleye harvest (4.9 million pounds) in 2015 approximated the mean harvest from 2000 to present (4.8 million pounds) but was below the mean harvest from the inception of individual transferable quotas (ITQs) (1984 to present; 6.4 million pounds). In 2015, the commercial Walleye fishery was composed mainly of the 2003 (age 12), and 2014 (age 1) year classes, with contributions from the 2011 (age 3), 2013 (age 2), and 2010 (age 4) year classes. Age 1 Walleye were mainly captured as by catch in small mesh (<3” mesh size) gill net fisheries. The lake-wide fall gill net survey also indicated a strong presence of age 12 and age 1 Walleye. Interagency trawling to assess year class strength indicated a strong 2014 year class and a strong 2015 year class. The fall gill net survey also indicated a strong 2015 year class which will recruit to the fishery in 2017. Overall, the abundance of fishable Walleye in the west and central basins is at a below average level, but is expected to improve by 2017.

The Walleye population in eastern Lake Erie consists of mixed stocks including those originating from east basin shoals, the Grand River (Ontario), United States tributaries, and immigrants from the western portion of the lake. Representation of older Walleye is typically greater in eastern Lake Erie compared to other regions of the lake. The greater average age of Walleye in the eastern basin is due in part to the contribution of older migratory individuals originating from the western basin. In 2015, the strong 2003 year class at age 12 represented 20% of the commercial harvest in Ontario statistical districts 4 and 5 combined, and the 2010 year class (age 5) represented 24% of the fishery. Ages 5 and 12 Walleye also comprised a significant fraction of the Walleye caught in the east basin Partnership gill net survey in 2015. Fishery and survey indicators were positive for east basin Walleye abundance although juveniles were not caught in the east basin Partnership survey.
