Fishing Boston Harbor: A Local Guide to What You Can Catch and Where to Fish
Boston Harbor has been a working waterfront for centuries, but it also offers some of the best urban fishing opportunities in New England. From striped bass blitzing baitfish near the harbor islands to flounder hiding along the bottom and bluefish chasing schools of mackerel, anglers can find a surprising variety of fish without traveling far from downtown Boston.
Whether you’re fishing from shore, a pier, or a boat, here’s a guide to what you can catch in Boston Harbor and where to find it.
Why Boston Harbor Is a Great Fishery
Boston Harbor sits at the intersection of freshwater rivers, tidal estuaries, and the Atlantic Ocean. This mix creates ideal habitat for both resident and migratory fish species.
The harbor’s deep shipping channels, rocky shorelines, islands, eelgrass beds, and tidal currents provide food and shelter throughout the season.
Fishing is typically best from May through October, although some species remain available year-round.

Each spring, large schools migrate north from the Mid-Atlantic and enter Massachusetts waters. By late May and June, stripers can be found throughout the harbor.
