[cool][#0000ff]There are varying theories on how the walleye got into Jordanelle. Since there are no natural barriers between Deer Creek and the upper Provo it is conceivable that a few wallies got "captured" by Jordanelle Dam. More likely they got there the same way they did in Deer Creek...from the livewells of anglers who thought they had a better management plan than DWR. Ditto for perch.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]Actually, the walleyes have not seemingly become numerous enough to create a noticeable effect on the Jordanelle fishery...either in terms of angler results or in predatation on other species. Of course that can change...as we have seen on other waters.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]The perch in Jordanelle are a mixed blessing. As in Starvation, they have supplemented the food supply for the predators after the chub population was diminished. No crawdads in Jordanelle, as there are in Starvation, so the smallmouth rely more heavily on perch. Their sizes and numbers seem to fluctuate according to the health of the perch population. And both browns and rainbows feed heavily on perch fry and yearling perch all year round. I wonder how well the trout would be doing without perch in their diets.[/#0000ff]

[#0000ff]No reason or excuse for the bucket bozos changing ecosystems to suit their own personal fishing preferences. But, like it or not, those other species are in the lakes and there to stay. In some cases they have proven more positive than negative. But, it is always potentially dangerous to start sprinkling other species around and messing up any chance at proper management.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]Too bad it is so difficult to track or trace the origin of illegal introductions. A fitting punishment might be to subject the perpetrator to a colonoscopy using an adult member of the species illegally introduced. Those with spines might cause some agony.[/#0000ff]
