I will try to find out if they are fertile or not. I really don't think that they are. When I bought them, I was told that the Hybrid Perch were for growing BIG bluegill and that the CNBG were prolific breeders and would procreate and make for a better forage fish.
In hindsight, I think I'll quit buying the Hybrid Perch and just stick with the CNBG. I have plenty of really large bluegill and since my goal is big bass I don't want them to have any competetition.
Disclaimer: I am using the term perch and bluegill interchangeably
