  • Invasive Snakehead Caught in Canton, Massachusetts

    • Sep 2, 2021

    • Massachusetts Division of Fisheries and Wildlife.

    • On August 27, an angler caught a northern snakehead from Reservoir Pond in Canton, Massachusetts. After obtaining and analyzing the specimen, MassWildlife confirmed this fish was a snakehead, an invasive species in Massachusetts. This fish was most likely released by a pet owner when it grew too large for its aquarium. Possession and liberation of snakeheads are both illegal in Massachusetts. Transferring exotic fish into local waterways can cause a host of problems, including competition with native species and spread of disease. This recent catch is the fifth confirmed snakehead documented in Massachusetts since 2002. All snakeheads found in Massachusetts were adults, and MassWildlife has found no evidence of reproduction at any of the locations where the snakeheads were caught.

      Anglers may confuse snakeheads with other native species like bowfin. Anyone who captures a fish that can be confidently identified as a snakehead should keep the fish, kill it, and report it to MassWildlife by emailing mass.wildlife@mass.gov or calling (508) 389-6300. MassWildlife encourages anglers who are less certain about the species of fish they have caught to send photos showing various angles of the fish. Under no circumstance should a suspected snakehead be transported to another location until identification is confirmed.

  • It's Time: Spotted Lanternflies are Hatching

    • Apr 28, 2023

    • Massachusetts Introduced Pests Outreach Project. Outreach Blog.

    • This year’s unusually warm winter and spring has led to the early hatch of spotted lanternfly (SLF) in states to our south.  Reports have come in over the past couple of weeks of SLF hatching from Virginia to Pennsylvania, and we anticipate them following suit here in Massachusetts in the next month.

  • Massachusetts State Agricultural Officials Urge Residents to Report Signs of Invasive Spotted Lanternfly

    • Sep 25, 2020

    • Massachusetts Department of Agricultural Resources.

    • The Massachusetts Department of Agricultural Resources (MDAR) today announced that it has identified two dead specimens of the spotted lanternfly (SLF) in Massachusetts communities, and is urging residents to report any sign of the invasive pest. The specimens were recovered in the towns of Milford and Norwood, and were brought into Massachusetts on materials shipped from Pennsylvania counties currently under a spotted lanternfly quarantine. Additionally, MDAR was recently notified that nursery stock with spotted lanternfly egg masses and adults may have been unintentionally imported and planted in several parts of Massachusetts.

      MDAR is urging anyone who has received goods or materials, such as plants, landscaping materials, or outdoor furniture, from a state with a known SLF infestation to carefully check the materials, including any packaging, for signs of spotted lanternfly. Currently, there are known introductions of SLF in Connecticut, Delaware, Maryland, New Jersey, New York, Pennsylvania, Virginia, and West Virginia. If any indication of SLF is found, residents should take a photo or collect the specimen, and report any potential sightings of the pest using MDAR’s online reporting form. Residents should look for large, gray insects, about one inch long, with black spots and red underwings, or inch-long, rectangular yellowish-brown egg masses covered with a gray waxy coating.
