White Perch. If your lake is landlocked, it may have gotten in witrh stocked striped Bass. The White Perch is a Temperate Bass of the same family as Striped Bass and White bass. They live in salt and brackish water and enter freshwater to spawn. They are good to eat if you can find the larger ones.
They must get in other ways too. We have them in many lakes and ponds that aren't stocked with anything. We also have them in the Connecticut river.
