They also catch them in the St. Joe on the fly while fishing for steelhead, St Joe is loaded with them. Saw a nice 6 -7 pounder brought in when I was there in March on a steelhead fly, a pink chartreuse egg type attractor fly. Walleye season was closed so it was released. Yes they are great eating.
Not many people intentionally fish for them with flies though they are usually an incidental catch in rivers when fishing for bass or trout.
