Threatened Northern Sunfish Discovered In Clinton County

northern sunfish

In early September, New York State Department of Environmental Conservation’s Rare Fish Unit Biologist Doug Carlson and technician Eric Maxwell identified nearly a dozen threatened northern sunfish in the Great Chazy River in the village of Champlain, Clinton County

Also known as the longear sunfish, the northern sunfish is a small, thin, deep-bodied fish that averages three to four inches in length. It is sometimes a colorful fish with an olive to rusty-brown back, bright orange belly, and blue-green bars on the side of the head. The northern sunfish has short, round pectoral fins and an upward-slanting gill cover flap that has a white and red flexible edge. It is often mistaken for a pumpkinseed sunfish.

The northern sunfish is a threatened species in New York State and it has suffered immense losses in Western New York. Biologists have speculated that several factors are involved, including interactions with non-native fish like green sunfish and round goby. This population of this recent discovery appears robust and quite localized.

    Since it is native maybe they should introduce it to man made ponds like the Boreas system
