Question: how to tell the difference between male and female walleye?
Answer: The anus on a male is circular while the anus of a female resembles a keyhole, and the female's will become larger once it is time for her to lay eggs. Examine the weight of your walleye. A male will weigh less and look slimmer than a female, with a more streamlined appearance; female walleyes are rounder and plump.
