I've raised several red fish in my backyard water garden that were caught legaly f/ Louisiana (16inches). My pond was about 3000 gallons at the time. I later released them in a local park pond. I'd like to imagine some kid hooking one,,,,,smile. Last year I made several calls and got the impression that most ponds just get too cool to keep Red fish esspecailly my east Texas pond. Most never reproduce even in the power plant lakes. I really haven't seen any data on the cold water kill off temperture..........I would be very interested if anyone has had experence w/ such a fantastic fish in their ponds!
