I hope the pump works out for you, it would be nice if you could keep the trout long enough to reach their maximum potential size, big tiger trout are some nice looking fish! Since your trout have lots of natural forage as well, if you could introduce them as fingerlings they'd be as close as you could get to a wild trout by the time they were adults. I looked up some trout hatcheries that produce tiger trout online, some of them seem quite expensive! I did find one in PA that recently opened a hatchery in WV, it'd probably be closer to me but is still like three hours away.
