Bender, here is a picture of the Tensleep state fish hatchery in Wyoming, home of the Yellowstone cut throat brood stock. It's kind of hard to see but there there is a 3" pipe with holes in it providing a strong circular current in this large round fiberglass tank full of trout, the trout were stacked in there like cord wood. The tanks are partially buried in the ground. Also note that these tanks are all located in the shade under a metal roof.
Here is another picture of some of these 6-8" trout taking pellets in the tank. Something on a much smaller scale such as Bruce's RAS system should work well.
