Why are the walleye regulations on Lake Superior different from those on the St. Louis River?
On Lake Superior, the restriction on the number of fish over 20 inches provides better protection to the mature female walleyes, which are the spawners, and are important to the population’s ability to naturally sustain its numbers. On the St. Louis River, the 2 fish bag limit protects the quality of the fishery by limiting the number of mature males and immature fish harvested while they are concentrated in the river and susceptible to heavy angling pressure.
