ALEWIFE, Mass. (WBZ NewsRadio) — 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.
“Because of interventions like fish ladders at the Mystic Lake dams, we’re starting to see that population come back,” she said.
By 2019, the herring population had grown to nearly 789,000. However, there was a dramatic dip in 2020 with only around 378,000 herrings reported.
According to the association, the state’s Division of Marine Fisheries attributed the decline to the statewide drought in 2016 that caused lower reproduction of the fish.
Despite that setback, the herring population continued to grow every year since, with more than 550,000 reported in 2021, and jumped to nearly 640,000 in 2024.
River herrings are not only an important food source for indigenous people but also play an ecologically significant role in both freshwater and marine food webs.
“The Alewife T station is named Alewife because of this fish,” Santollani added.
She credited the hundreds of volunteers who spend every day counting the herrings passing by during migration season.
“From April through June, seven days a week, 7 a.m. to 7 p.m., [each volunteer] going for an hour to count how many herrings they’re seeing passing the dam,” she continued.
