Thanks for your responses. So you would leave a handful of the brooders in there all season and just assume that they're not going to eat too much of the fry? I'm guessing it would take a while for the fry grow to reproduction size. I do have a lot of aquatic vegetation in my main pond for cover, but it's only 1/8 acre pond and I have a lot of predators. I haven't had much luck with shiners in the past so that's why I'm raising them in a brood pond
