River herring are becoming scarcer along the New England coast for a variety of possible reasons, be they changing food chains, pollution, climate change – or commercial fishermen catching too many of these creatures for use by health-supplement companies promoting the benefits of omega 3.
Herring are an important food for many other fish. Their declining numbers ought to spark stepped-up conservation efforts by state and federal regulators. The states have a big role because while these fish mostly live in the sea, they return to rivers to spawn.
