Sounds like the right track to me. I think they will reconsider the impact of predators though, as soon as they figure out how all their hard work ended up in some birds or otters.

From the sounds of it, does it sound like they plan to release the offspring as fry? (I didn't get the impression that they planned on holding the fish much longer than required to clip them.)

I hope the system is a success. Sounds strikingly similar to what I have been promoting. But then, I'm just a fisherman.
