From what I was told, be it right or wrong, somebody from the Northern states moved to a town in Ks. Decided to stock his pond with white perch because he liked to eat them.The pond overflowed during a severe rainstorm and the fish eventually made it into Kaw Lake, and Sooner Lake as Sooner pumps water from the Arkansas River to keep its lake full. I can't confirm that story, but remember reading that somewhere.The way to tell if it's a true white perch is that their main dorsal fin doesn't fold down. It's rigid which prevents a lot of fish from using them as a food source while they decimate Walleye, crappie and sand bass eggs.Walleye or White Bass eggs can make up 100% of White Perch diet depending on which fish is spawning. During a three-year study, this diet was found to be unique in that: 1) eggs were eaten for a comparatively long time, 2) they were the only significant food item eaten by adults during two of the three years, 3) large volumes were eaten per individual, and 4) most fish were feeding. White Perch also feeds heavily on minnows Notropis spp. (Schaeffer and Margraf 1987). The collapse of the Walleye fishery in the Bay of Quinte (on the north shore of Lake Ontario) coincided with the increase in the White Perch population and may have been a result of egg predation and lack of recruitment (Schaeffer and Margraf 1987).[URL unfurl="true"]https://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=777[/URL]</blockquote>
