If the five unexpected salmon are a sign of a comeback in the Connecticut River, this could be really exciting.
Nate Schweber writes at Al Jazeera America, “By the fall of 2015, the salmon of the Connecticut River were supposed to be doomed. The silvery fish … went extinct because of dams and industrial pollution in the 1700s that turned the river deadly. In the late 1800s a nascent salmon stocking program failed. Then in 2012, despite nearly a half-century of work and an investment of $25 million, the federal government and three New England states pulled the plug on another attempt to resurrect the prized fish.
“But five Atlantic salmon didn’t get the memo. In November, fisheries biologists found something in the waters of the Farmington River — which pours into the Connecticut River — that historians say had not appeared since the Revolutionary War: three salmon nests full of eggs.
“ ‘It’s a great story,’ said John Burrows, of the Atlantic Salmon Federation, a conservation group, ‘whether it’s the beginning of something great or the beginning of the end.’ …
“The streamlined wild Atlantic salmon, genetically different from their fattened domesticated counterparts, which are mass-produced for human consumption, are so rare that anglers spend small fortunes chasing them across Canada, Iceland and Russia. …
“The stocked salmon continued to die off through the early 1970s. Gradually, scientists began to learn the importance of different strains of salmon and their close relatives, trout. In 1976 the program was able to acquire Atlantic salmon eggs from the Penobscot River in Maine, the closest surviving population both physically and genetically. This strain was still different from the lost native strain of the Connecticut River, but less so than their Canadian cousins, previously stocked there. In 1978, 90 fish from the Maine strain managed to make the two-year, 6,000-mile migration out to the food-rich Labrador Sea off of Greenland and then return to the Connecticut River. …
“As only 54 salmon returned to the Connecticut River in 2012, the U.S. Fish and Wildlife Service pulled out of the restoration program. New Hampshire, Vermont and Massachusetts followed. Connecticut opted to continue stocking a small number of salmon …
“Then in the fall of 2015, biologists found five adult Atlantic salmon swimming past the Rainbow Dam on the lower Farmington River. On a hunch, they searched likely upstream spawning habitat and there found the three nests full of eggs.
In the spring of 2016 they will hatch the first wild salmon into that river in two centuries.”

In North America, Atlantic salmon migrate up rivers and streams to reach spawning grounds in New England and Canada.
