The fish species listed as Endangered, Threatened, or Special Concern under the Massachusetts Endangered Species Act range from the coldwater Longnose Sucker found in flowing waters of western Massachusetts, to the prehistoric-looking Shortnose Sturgeon found in the larger Connecticut and Merrimack Rivers, to the American Brook Lamprey found in select watersheds of southeastern Massachusetts, Cape Cod, and Martha's Vineyard.
Freshwater fishes are vulnerable to sedimentation, changes in water temperatures, excess pollutants, extreme water level changes, and barriers to movement, such as dams or poorly designed stream crossings. For more information about these species, read the fact sheets that can be accessed through the MESA List .
