Portland Press Herald: There was a surprising increase in the number of river herring passing the Amoskeag Fishways Learning Center in Manchester this spring where the herring run was already the biggest it’s been since 2000, biologists say.

On the Kennebec River in Maine, the removal of dams and other projects has boosted the herring run back up to 2 million a year, with a goal of bringing it up to 5 million.

As of May 15, a total of 17,333 river herring were counted passing through the fish lift at Essex Dam in Lawrence, Mass., the first dam upstream from where the Merrimack River empties in to the Atlantic Ocean.

The figure is almost twice the total of all last year’s run and more than 20 times the run in each of the two years before that.
