Pond Boss Forums Thread Like Summary - Walleye disrupt perch success? Please explain

Can someone help me understand why perch and Walleye can't happily coexist in a public body of water?

see this article that encourages people to keep any Walleye they catch.

Anyone on the forum from Idaho?

Unusual Catch raises Concern in Idaho

Very easy to explain - is in first sentence

an invasive predatory fish - to Idaho.

WE and YP co-exist in many waters where both fish are natural to the location.

Walleye in this lake were not part of the IDNR's plan for the fishery despite what the anglers think about it. The illegal addition of WE interfered with their design and experiment for the lake. Thus the concern.
