Atlantic Salmon

Atlantic Salmon

Atlantic Salmon in Massachusetts are functionally extirpated as sea-run fish, with only rare strays returning to the Merrimack River or occasional fish from legacy programs in the Connecticut River.

However, the state maintains the last wild Atlantic Salmon population in Massachusetts at Wachusett Reservoir, where landlocked salmon averaging 20 inches provide excellent fishing opportunities.

These landlocked salmon are genuinely wild, calling the reservoir waters home rather than the ocean, and represent a unique fishery.

Physical Characteristics:
  • Atlantic Salmon are characterized by their streamlined silver-blue bodies with X-shaped black spots above the lateral line, blue-green coloration with silver coating in non-reproducing adults, and distinctive bronze/dark brown coloration with red-orange spots during spawning periods.
  • In Massachusetts waters, they typically weigh 1-6 pounds with some reaching larger sizes, averaging 20 inches.
