Lake Ontario and St. Lawrence River Fisheries Research
What We Do
Our principal function is to help manage the fish resources within Lake Ontario (Cape Vincent Fisheries Station) and the St. Lawrence River (Region 6 Fisheries Unit). By managing, we mean 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 and salmon and the amount of available preyfish, and evaluate success of fish stocking programs dedicated to restoring native species and enhancing sport fisheries.
Although most of us are trained biologists, much of our time is devoted to serving people. We regularly respond to questions from the public about the changes currently underway in Great Lakes waters. We frequently attend meetings to inform people of our work and findings. We also encourage their interest and involvement.

Cape Vincent Fisheries Station Services
For many, the best thing we provide are the special services to visitors at the Cape Vincent Fisheries Station. We operate a small aquarium and educational center, maintain a riverfront picnic area, furnish accessible docks for fishing, and provide overnight dockage for transient boaters visiting Cape Vincent. These services are free-of-charge, as we try to make all our visitors feel at home and welcome.
