I think you have a solution looking for a problem. I know nothing about longear sunfish but I’ve never heard of them being a problem.

But, I also like green sunfish. They only spawn annually so can’t really cause problems. And, they out fight a pansy ass bluegill every time.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP Grandpa
