  • NYDEC and Canal Corporation Announce Comprehensive Effort to Protect New York's Waters from Aquatic Invasive Species Round Goby

    • Mar 24, 2022
    • New York State Department of Environmental Conservation.

    • The New York State Department of Environmental Conservation (DEC) and the New York State Canal Corporation today announced a new comprehensive effort, including a new rapid response plan, to combat the potential spread of the round goby, an aquatic invasive species, to the Lake Champlain Basin following the discovery of the fish in the Hudson River near Troy in July 2021. The round goby is one of the biggest threats to New York waters, particularly Lake Champlain, and DEC lists round goby as a prohibited invasive species in the New York Code of Rules and Regulations. Native to Europe and Asia, this fish was introduced in the Great Lakes in 1990, and spread throughout the lakes' system. Round goby reproduces quickly, outcompetes native benthic fish species for food and habitat, eats the young and eggs of other fish, and can transport botulism up the food chain to waterfowl. Working with partners, the agencies will develop a rapid response plan to take effect before the opening of the Canal system on May 20 to identify appropriate actions if round goby enter the Champlain Canal.

  • NYDEC and Canal Corporation Announce Second Year of Sustained Effort to Protect New York's Waters from Aquatic Invasive Species Round Goby

    • Jan 25, 2023
    • New York State Department of Environmental Conservation.

    • The New York State Department of Environmental Conservation (DEC) and the New York State Canal Corporation continue to implement a comprehensive effort, including a rapid response plan [PDF, 1.73 MB], to combat the potential spread of the round goby, an aquatic invasive species (AIS), to the Lake Champlain Basin following the discovery of the fish in the Hudson River near the city of Troy in July 2021. Aquatic invasive species can out-compete native fish species, disrupting ecosystems and damaging local economies dependent on recreation.

  • NYS DEC Encourages Delaware River Anglers to Report Invasive Snakehead Sightings

    • Aug 26, 2020
    • New York State Department of Environmental Conservation.

    • New York State Department of Environmental Conservation (DEC) Commissioner Basil Seggos today encouraged anglers in the Delaware River to be on the lookout for northern snakehead, an invasive fish native to Southeast Asia. A northern snakehead was recently caught in the Callicoon area of the Delaware River. Given the right environmental conditions, this invasive species can prey on and compete with other fish, upsetting the natural balance of local ecosystems. "Northern snakeheads are listed federally as injurious wildlife, and New York State law prohibits their live possession," Commissioner Seggos said. "Any snakehead caught should be killed immediately and not released back into the water." In the event an angler catches a northern snakehead, DEC advises anglers to report the catch to the regional NYS DEC fisheries office, DEC's Invasive Species Bureau at isinfo@dec.ny.gov or (518) 402-9425, or submit a report through iMapinvasives.
