I put in 100 walleye. I dont know how many of the perch are both male or female-I was just putting them in as we caught them with the idea that the more I put in the btter the chances were that I would have both male and female. I am hopping that with the 30 I put in I should have some of both and once ice is off I ama going to continue to add more perch beofre they spawn. The trout I am still questionalbe about
