January 6, 2020 — A record number of Atlantic salmon eggs were laid in the East Machias River last year, an indication that an eight-year effort to restore the endangered species in the river is paying off.
Biologists counted 61 redds, or nests that fish build for spawning, buried in several inches of river gravel spread between Crawford and East Machias. That’s six times the number of redds counted in the East Machias River since the Downeast Salmon Federation began tracking salmon egg nesting patterns there 20 years ago, said Dwayne Shaw, the federation’s executive director.
“This is just huge,” Shaw said. “A number like this hasn’t been seen in the river in decades.”
The federation counted 12 redds in 2016, four in 2017 and 10 in 2018. Over the past 20 years, the East Machias River on average has yielded about 10 redds a year.
With each redd containing about 4,000 eggs, the 61 redds are carrying about 240,000 eggs — enough, given the rigors of nature and the presence of predators, to produce about 2,000 salmon that will survive in the river over the next two years and become smolts, fish mature enough to go to sea, Shaw said.
