The Upper Walleye, otherwise known as Pickerel, Management Unit (UGLMU) have long been a significant species is drafting a in Eastern Georgian Bay.

Walleye stressors, especially Historically, Georgian Bay was famous meaningful harvest controls. for its abundant Walleye populations Our hope is that harvest and the exceptionally large size of many reduction will be a key fish. This supported a productive and component of the future valuable Walleye fishery. Walleye Management Plan.

Stressed Walleye populations include the Moon River, Magnetawan River, Musquash River and Severn Sound. Walleye populations in the Key River and Shebeshekong River are severely stressed. In the Moon River, annual Walleye spawning runs used to number over 30,000 fish.

In years of both low and high attributed to a number of human- water levels and flows, Walleye likely use caused stressors, including: alternative spawning sites, where hatching Walleye Harvest and survival could be jeopardized. There are four major fisheries in Eastern Invasive species Georgian Bay – commercial, recreational, The introduction of Alewife in the mid- First Nation commercial and First Nation 1930s had significant negative impacts on subsistence.

WALLEYE HARVEST HAS AN IMPACT Walleye are typically not a catch and release species because they taste good. If over-fishing is contributing to population declines, we should be practicing catch and release for Walleye angling, especially for larger, female Walleye. By reducing our harvest today, we help to ensure Walleye can be fished for in the future. Perhaps the most effective means of Photo Credit: Andy Metelka restoring Walleye stocks is to protect Gill net fisheries for Walleye must be the large female Walleye which are so eliminated. Gill nets indiscriminately critical to reproducing this species. Most kill these large female Walleye. Sports large Walleye are females, and their egg fishing should have catch limits reduced production is impressive. For example, to two fish per day, with all Walleye over a four year old Walleye can produce 55cm required to be released. And 50,000 eggs, while females over seven finally, those large Walleye which have years have been found to carry over survived all of the natural and human 400,000 eggs. These fish are far too hazards to return to their spawning beds valuable to be killed for a meal. should not be harvested before they have had an opportunity to reproduce. There is a need to reduce All of our efforts to restore and enhance Walleye harvest. Over the past spawning habitats over the past decade 30 years, efforts to rehabilitate are futile if we kill the majority of fish spawning sites, manage water before they can spawn. levels, stock Walleye, restrict It is time we stopped lamenting the sport fishing and introduce demise of Georgian Bay’s famous commercial fishery quotas Walleye or trying to find someone to have failed to restore Walleye blame.
