Most invasive insects are hidden away for the winter, but you still might encounter them when you split wood, move outdoor furniture indoors, or admire evergreen plants while on a hike. Learn more about invasive pests you may come across and how to report them.
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.
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.
