I understand the damage that can be done by introducing certain species of fish, but I just don't see that happening (in Utah) if crayfish were ever introduced. Am I underestimating their devastating potential?[/quote]
What good do crayfish do for Strawberry Reservoir? Kolob Reservoir?
Crayfish DIRECTLY compete with trout.
They certainly do change systems. Not all of our fisheries have, or should have, fish species that prey on crayfish.
So the guys taking crayfish home to eat should simply be able to tell the CO "we're taking them home to eat..." and be OK. What about the guys taking them home to use as live bait in a lake currently void of crayfish? What do they tell the CO? "we're taking them home to eat them...".
It's not just about the crayfish. It's also about transporting water, and the other critters living in the water -- mussel veligers, whirling disease, milfoil, etc.
