Lake Ontario Fisheries Research Unit
Based at the Cape Vincent Fisheries Station, the DEC Lake Ontario Fisheries Unit manages the fish resources within Lake Ontario and the St. Lawrence River (DEC Region 6 Fisheries Unit) by monitoring the status of fish populations and evaluating the need for specific management actions. On Lake Ontario, we assess the balance between numbers of trout and salmon and the amount of available preyfish, and evaluate success of fish stocking programs dedicated to restoring native species and enhancing sport fisheries.
Research Vessel Seth Green
The R/V Seth Green (PDF) is used to conduct annual assessments and surveys of Lake Ontario's fish stocks. Most sampling programs are carried out in conjunction with the Ontario Ministry of Natural Resources or the USGS's Biological Resource Division's office in Oswego, NY. Vessel time is also available to other researchers with compatible interests.
Interagency Management Coordination
New York cooperates with other jurisdictions on Lake Ontario and the St. Lawrence River to manage fish populations that roam widely as a shared resource throughout these water systems. Coordination between jurisdictions is done by the Great Lakes Fisheries Commission's (GLFC) Lake Ontario Committee (LOC). Joint decisions are made annually concerning management and harvest policies that affect all jurisdictions.
