I just didn't like how he was trying to make it sound like these are "easy" fish to keep, just because they've survived for a little bit in his setup. Trout and salmon are demanding species requiring cold, clean water. He says they can be kept in roomp temp water if acclimated when young. Well in the wild, yes they may experience temps of over 65-70 but it is for a short time of the year. We'll see how long they last...
Don't get me wrong, I'm excited to see someone try a species that is very rarely kept. I just think if your going to keep a coldwater fish, you should have a coldwater setup, not an outdoor pond with no temperature control.
I also feel that aquiring these fish was not exactly legal, since they are too small to have been taken on hook and line (show me where its legal to catch gamefish with some other method). Besides that, there are size limit restrictions on that river
