[quote isda]I have a question... What makes a "great perch fishery" and what can we do to create one here in UT?[/quote]
That's the real trick...the problem is that perch are not well-suited (or, in some cases, too well-suited) for utah waters. Perch either tend to overpopulate stunting their growth rates and fishermen aren't able to harvest them quickly enough or abundantly enough to control their populations or they cannot reproduce enough to overcome predation.
So, in order to have a great perch fishery, we would have to control their numbers to the point where their growth rates are at their optimum. A good predator/prey relationship would certainly help...but even where perch predators exist, habitat issues don't allow the perch to reproduce as they need.

It refers directly to your question in regards to Utah and perch.
