Fishing
Many popular recreationally fished species can be found in the rivers, including striped bass, menhaden, and bluefish, particularly near the mouth at "the Spit".
Reminder: It is illegal to catch river herring in the state of Massachusetts!

Shellfishing
Shellfish beds are now open on the North River
The North River has shellfish beds that are conditionally open from roughly December through May 31, from the 3A bridge to the mouth. The beds are only open to residents with a valid shellfish permit. Shellfishing is prohibited in the South River.
