While mercury is very toxic...the primary contaminates in the waters are (in addition to mercury) PCBs, insecticides, various fertilizing compounds for lawns, and storm drain runoff from roadways.
The Mercury contamination originates in the exhaust of coal fired power plants. The PCBs come from electrical power lines and transformers, the insecticides come from state and local mosquito abatement efforts, The fertilizers come from peoples lawns and the run off come from automobiles.
Most of the Rivers in Mass have at one time been used as open sewers for various factories and cities such as Boston piping house hold waste, untreated, directly into the water.
So are the fish safe to eat? Yes in moderation.
It can be argued that the fish you catch are safer than the fish you buy in the market because you know it is wild caught and not farm raised in a toxic farm pond somewhere in Asia. If you want to buy fish at the store make sure it is either wild caught in US waters or is farm raised in the US. Any fish sourced from Asia is as toxic if not more toxic than local fish.
