Theo, are you asking me how long walleyes live? You know better than that -- the answer is "it depends."

Sorry, couldn't resist. Actually, we've got some 10 year old walleyes in one 22-acre pond. My son caught one last summer that was 29 inches! Whew. However, there are darn few left at that age. I'd say the bulk of them are gone by age 6 or 8??
