I have noticed on many of our trips up to Lake Mindemoya on Manitoulin Island, over the past few years, that we have not caught any walleye in what was once a primary walleye lake. When a walleye was caught, it was usually very small. On the other hand, an abundance of jumbo perch is always easily achievable. Knowing that perch are a favorite food source for walleye, is it possible that over fishing these walleye has caused this imbalance? I also realize that Perch do prey on other small fish such as walleye fry and eggs which would ultimately have a drastic impact. What are your thoughts on the matter and how could this problem be reversed?Posted on October 15th, 2015
Tough to give you an educated opinion without knowing the management history that would include trap-netting, creel-census and other data. It could be that the walleye have moved to different areas of the lake other than where you traditionally fish for them.
