CC, all good questions. Hopefully they will stay feed trained, they have not seen another fish to eat except their brothers and sisters. I was told that they will grow fast if kept in a RAS, On 4-5-2022, 3.25" fish that were hatched on 2-5-2022 would be 10"-12" in length in October. As to seeing them feed, I have no idea. When I had the smaller ones in the RAS, they were being fed sinking feed.
Maybe there will be some genetic "memory" in these fish, as it's been a few generations that the parents/grandparents, etc. have solely been on feed in a RAS system.
My pond is currently about 48" low, but I have plenty of depth.
