I like fishing for all of these species, but I really like fishing for ciscoes. Ciscoes, also known as tullibees (tullies) or lake herring, are closely related to whitefish. Need to tell the two ...

As perch and tullibee populations decline, walleye consequently swim in shallower waters than normal to seek fish to eat -- making them easier to catch and worsening the overfishing issue.
