[quote TubeDude]"Erie also has walleye. In every case where perch and smb thrive together, you also have walleye in the mix. Not so at Jordanelle."
[#0000FF]So then, what is your evaluation of Deer Creek. Perch and walleye coexisted for decades in that lake. Plenty of perch and plenty of healthy walleyes. But once the smallmouths were dumped in they ate baby perch before they got big enough for the walleyes and both perch and walleyes took a dive. Today there are almost no perch at all, far fewer walleyes and large browns. Trout still do well on zooplankton but the smallies are overpopulated and stunted...just like Jordanelle.
In this case the smallies totally wrecked an ecology that had been doing well for many years before they came along.

Careful, that uncomfortable finding goes against their theory/rant and thus must not be "factual". [
] (and Deer Creek has been much, much worse for smallies than Jordanelle for a very long time.)
A couple of final housekeeping items.
Here is a native range map for yellow perch.

and Smallmouth bass.

They are almost identical!
It is not consistent with evolutionary theory for two species to co-evolve and be incompatible. Incompatibility typically occurs when two species that have not co-evolved are put in a situation together, such as smallmouth bass and Utah chubs.
Finally, a quote from the posted range sheet on smallies. (under "impact of introduction")
Smallmouth Bass were introduced into Flaming Gorge Reservoir to reduce the Utah Chub Gila atraria (Teuscher and Luecke 1996)
And it worked! [cool]
