How to prepare fish from Otter River (between the Seaman Paper Dam in Templeton and the confluence with…

Some contaminants build up in fat and skin, so cleaning and cooking can lower your exposure. Others — mercury and PFAS — are in the muscle itself and trimming does nothing.

PCBs

  • Skin the fish — most of the contaminant sits in the fat just under the skin.
  • Trim the fatty areas away: the belly flap, the top of the back, and the dark lateral line down each side.
  • Cook on a rack — grill, broil, or bake — so the fat drips off the fillet.
  • Throw the drippings out; don't use them for soup, sauce, or chowder.
  • Choose smaller, younger fish — they've had less time to build it up.

Is it legal to keep?

These are Massachusetts's statewide limits — a water-specific rule may override them. Always verify the current regulations before keeping a fish.
