What do you want out of this pond? Is it strictly table fare you're after? You mentioned you thought you had a catfish when you hooked these guys, what other species are present?
HBG are most often declared to revert back to GSF. This is impossible from a purely scientific standpoint, but in a practical, real world scenario GSF is probably a good a description as any.
Following conventional wisdom, there's no point retaining the F1's for genetic purposes, so If my goal was food, I would harvest them when they reached a size I considered acceptable. If you received more of these than you did BG, you may find yourself short on forage, IF you were counting on forage to sustain another species.
