The main fishing goal in Minnesota and somewhat in Wisconsin is walleye. Since Minnesota leads the nation in per capita boats and fishing licenses they have a legitimate claim to to most of the population having eaten non-imported walleye probably more so than say Hoosiers eating southern farm raised catfish instead of home caught. I’ve had local fresh caught walleye (but rarely) in restaurants in Minnesota. It is very much a regional staple in restaurants where walleye is on the menu more than naught in Minnesota if fish is on the menu. No other state, including Wisconsin, can make that claim. Wisconsin is more apt to substitute perch and white fish over walleye in many instances. Most of the supply of walleye comes from the Canadian province of Manitoba adjacent to Minnesota.
What about Lake Erie walleye??? Northeast Ohioans love their fresh-caught walleye. And boy is it GOOD.
