DEC Fisheries Research Vessel Seth Green
The R/V Seth Green is operated by the New York DEC Lake Ontario Unit based at the Cape Vincent Fisheries Station. It's primary function is to conduct annual assessments of Lake Ontario's fish stocks to provide information necessary to manage the lake's resources. Most of the 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.
The Seth Green is a full displacement hull designed primarily for trawling, but capable of carrying out a wide variety of sampling tasks. The vessel is rigged for stern trawling with split winches and net drum, and features an enclosed shelterdeck where the fish processing can be carried out in relative comfort. The shelterdeck also houses a 36" Crosely gillnet lifter and secondary steering station. The area also provides a dry area for sounders and computers during hydroacoustic surveys. In 1996 outriggers were added to the vessel which has allowed the crew to work in less favorable weather. This has increased the safety of the crew as well as the quality of the survey results, especially in hydroacoutics work.
