2026 regulation year
Massachusetts Largemouth bass 2026 — Season, Bag Limit, Size Rules
Micropterus nigricans
Last updated
Massachusetts's largemouth fishery is spread across the southeast-MA pond tier (Long Pond Lakeville, Assawompset, Pocksha, Snipatuit, Great Herring Pond), the Berkshire reservoir tier (Pontoosuc + Onota + Otis + Cheshire), the central-MA reservoir + Connecticut River backwater complex, and the eastern-MA recreational reservoirs (Lake Cochituate, Lake Quinsigamond, Whitehall Reservoir). MA's standard rule is a 12-inch statewide minimum + 5-fish daily aggregate across largemouth + smallmouth — no closed season, no pre-spawn protection (unlike NJ + PA, which close or restrict). Trophy-class largemouth in MA tend to come from the warm shallow ponds of Plymouth + Bristol County; trophy-class fish over 7 lb are caught annually but the state record (15 lb 8 oz from Sampson's Pond, 1975) is a long-standing record. Bass tournaments are common across the eastern + central MA reservoir tier; MassWildlife issues a separate special-event permit for tournaments above 25 boats.
