Round Whitefish

Prosopium cylindraceum

Round whitefish lives in lakes with a well oxygenated deep zone and is native to northern New York and mostly lakes of the Adirondack Mountains. Also, it has been known as non-native to the Oswegatchie watershed (previously stocked) with no records since 1955. Most of its range has decreased, and it is extirpated from lakes of the Upper Hudson watershed. Today, round whitefish is known from only 8 historic sites, and a stocking program has established two additional self-sustained populations within its former range. It is classified as Threatened.
