Canadian eel tracked on 2,400-kilometre migration to Sargasso Sea

October 27, 2015 — It’s a mystery that has puzzled scientists for a century — how swarms of baby eels appear in the Sargasso Sea near Bermuda when adults have only been found in faraway places like Canada’s St. Lawrence River.

For the first time, Canadian researchers have tracked an adult female eel from Nova Scotia all the way to the northern edge of the Sargasso Sea with a satellite tracker — a 45-day journey of about 2,400 kilometres, described in a new paper published today in Nature Communications.

If they can confirm the path taken by that eel is the typical migration route used by Canadian eels, that may help scientists figure out measures that could be taken to conserve the endangered fish.

American eels, known by the scientific name Anguilla rostrata, are found in watersheds from Venezuela in the south to Greenland in the north, says Julian Dodson, a University of Laval researcher who co-authored the new paper.

In Canada, they historically lived throughout the St. Lawrence Seaway and Great Lakes, although their populations have fallen dramatically in the past 20 years, largely because of fishing and hydroelectric dams that they have trouble crossing.

Males typically live further south than females.

MAINE: Big changes are occurring in one of the fastest-warming spots on Earth

October 25, 2015 — Sandwiched on a narrow sandbar between Yarmouth’s harbor and the open Gulf of Maine, the fishermen of Yarmouth Bar have long struggled to keep the sea at bay.

Nineteenth-century storms threatened to sweep the whole place away, leaving Yarmouth proper’s harbor more open to the elements, prompting the province to build a granite cribwork across the quarter-mile bar, behind which the hamlet’s fishing fleet docks. Global warming has brought rising seas, a two-story-high rock wall to fight them and the hamlet’s designation as one of the communities in the province most threatened by climate change.

Now, snaking around the snout of Nova Scotia and into the Gulf of Maine is a new, unseen threat to Yarmouth Bar and hundreds of coastal communities in Maine, eastern New England and the Maritimes: currents fueling the rapid warming of the sea.

The Gulf of Maine – which extends from Cape Cod in Massachusetts to Cape Sable at the southern tip of Nova Scotia, and includes the Bay of Fundy, the offshore fishing banks, and the entire coast of Maine – has been warming rapidly as the deep-water currents that feed it have shifted. Since 2004 the gulf has warmed faster than anyplace else on the planet, except for an area northeast of Japan, and during the “Northwest Atlantic Ocean heat wave” of 2012 average water temperatures hit the highest level in the 150 years that humans have been recording them.

Murder for Lobster

July 30, 2015 — On the morning of June 1, 2013, Venard Samson motored across the mouth of Petit-de-Grat Harbour in a small fishing boat. The narrow harbor, off the southeastern coast of Nova Scotia, is wedged between Petit-de-Grat Island, where he lives, and the wooded tail end of a larger island known as Isle Madame. By 6:30 a.m., he’d pulled one line of lobster traps and glided past a green navigational buoy. The North Atlantic, known for its rough winds and heavy swell, stretched out before him, so flat he could have passed a straight razor over its surface. “The water was right dead and calm,” he later recalled. “It was a nice damn day, clear, you could see anything.”

Then, he spotted the dark shape. It was floating along an uninhabited stretch of shoreline the fishermen all knew as Mackerel Cove. At first, Venard thought little of it; he had seen dead deer there before. But as Venard pulled closer, he discovered a banged-up fiberglass skiff, a small oceangoing vessel. It was waterlogged, its sideboards cracked and its bow barely a foot above the water line. No one was on board.

Venard circled the damaged boat three times, and discovered a floating gas tank and some green rope tangled around an anchor. The skiff’s outboard motor was missing, and its bowline, the rope that ties to the front of a boat, was apparently cut. Venard, a short man with a laborer’s physique who often speaks in an excitable squawk, picked up his radio and called the Canadian Coast Guard in Halifax, some 120 miles to the southeast. No, his GPS plotter wasn’t working. He’d have to drop a lobster trap to mark the spot. Around 6:55 a.m., the marine VHF radio cackled with a universal distress call: Pan-pan, pan-pan, pan-pan. All mariners were requested to be on the lookout and report any sightings of a man overboard.

Venard towed the skiff back toward the wharf and handed it off to another lobsterman. In some 50 years of fishing, neither man had encountered a situation like this. But both immediately wondered what had happened to Philip “Bowser,” who often roared around in the beat-up skiff, which he christened the Midnight Slider. The missing man’s full name was Philip Joseph Boudreau, but no one called him that because another local fisherman had the same name. A bull-necked man, 43 and going soft around the waist, Philip didn’t have a license to go lobster fishing. Islanders caught glimpses of him and Brodie, his blonde Labrador, cruising around under the light of the moon.

Later that morning, a ball cap washed ashore and a pair of boots were found floating in the harbor. It seemed Philip Boudreau was gone.
