Ranger says "Also, would these males be sterile or just male?" Neither. Hybrids males & females would be fertile and some females would be present in the stocking - probably 5%-20+% females present depending on the cross and selection of fish individuals. I think you or the fish biologist miss communicated.
Why do you not want fish in the pond?
