November 19, 2025 — It’s a plentiful year for River Herring in Massachusetts.
Daria Santollani is the senior engagement manager at the Mystic Watershed Association, the organization that tracks herring population and migration every year since 2012.
She told WBZ NewsRadio that this year, volunteers reported the highest number of herring passing through the Boston Harbor into the Mystic River, at nearly 815,000.
“It’s just amazing that the largest migration of herring in Massachusetts happens in the most urban watershed,” she said.
In the past, overfishing depleted the herring population. In 2012, the association reported the herring population was only around 21,052.
