[reply]The problem is not to many predators......Its the lack of food or food fish.....
Jordanelle is a world class fishery now but with out the proper management it will fall out like all the rest has in the past and here is a few that has.....
1. Yuba
2. Deer creek
3. Lake Powell
4. Starvation
5. Pineview
6. Willard
7. Utah lake
And that is just a few, Now some have been turned around like Willard, Lake Powell, how not by getting red of the predators like you say, To me that is just another cop out for lack of management by the DWR when all it takes is a food fish like perch shad or shiners ....
Every time a lake gets in truble the first thing that is said is TO MANY PREDATORs what a cop out.......

This post shows a complete lack of understanding...a lake can only hold so much biomass; once that biomass is tied up in predators, there is little/no room for prey. You seem to hold the notion that our DWR should be raising and stocking forage fish for the predators...this idea is ridiculous. Scenario: if the mountain lions were so numerous that they had eaten their prey base out and were starving as a consequence, the answer wouldn't be for the DWR to raise bunnies and deer...the answer is to control the predators. A healthy ecosystem has numerous prey species and a limited number of predators...not the other way around.
Also, chubs were not totally eaten out at the Gorge by smallmouth alone....smallmouth had lots of help from stunting lake trout (the largest predator in the lake). Lake trout played a significant role by being able to eat the larger chubs that smallmouth couldn't. If you were to look at other reservoirs with smallmouth and chubs (like Piute, Otter Creek, and Minersville...not to mention Newcastle with its smallmouth and golden shiners) you will find that the smallmouth are capable of growing very large but unable to totally control the chubs. Jordanelle did have some recruitment despite the perch and limited recruitment is not always a bad thing...but too many perch could limit the recruitment way too much which is a bad thing.
I agree with Fishhungry, though...all of us "wanna-bes" don't know nearly as much as the professionals.
