They're a relative of whitefish, so aside from being a little boney, they're decent eating even though some consider them not fit for food. I like them, but prefer perch, walleye and pike for the table.
The funnest part is that cisco are aggressive and they school, so the action is often fast and frequent. They also fight hard. The 18"-ish cisco fought noticeably harder than the 21"+ walleye did.
