Sea turtle strandings surpass 500, second-highest on record

January 3, 2016 — For the first time since the Wellfleet Bay Wildlife Sanctuary started rescuing endangered cold-stunned sea turtles in 1982, the sanctuary recovered living cold-stunned turtles in January, according to a statement from the sanctuary.

Usually, the season ends by Christmas.

Since November, rescuers with the sanctuary have recovered 520 turtles from Cape Cod Bay beaches, making it the second-highest stranding year on record.

Last year, 1,200 turtles were stranded, according to the release. The vast majority of turtles that strand here are Kemp’s ridleys, which are born on beaches in Mexico and Texas.

Fishing for a solution for endangered right whales

December 29, 2015 — Sometimes technology solves a problem, sometimes it makes it worse.

When researchers at the New England Aquarium and the Center for Coastal Studies in Provincetown examined ropes recovered from whales entangled in fishing gear from 1994 to 2010, they found that entanglements for North Atlantic right whales, the world’s most endangered great whale species, accelerated dramatically from 1993 to 2010, in both frequency and in the severity of the entrapment.

The culprit, scientists believe, is a new type of rope known as Polysteel, that rope manufacturers began making and marketing to fishermen and others in the marine trades as being 40 percent stronger and more durable than other synthetic ropes. Plus, the lobster industry also shifted from wood to wire traps that allowed them to use heavier gear and for the pots to stay in the water through the winter, increasing the likelihood of interaction with whales.

Even though fishermen already employ weak links designed to break and separate the line from the buoy when a whale pulls on it, researchers found the lines themselves were still doing a lot of damage.

“It was a huge change,” said Amy Knowlton, the lead author of the study and a research scientist with the New England Aquarium working to reduce the risk of whale entanglement and death from fishing gear and lines. Scientists put the number of North Atlantic right whales that can be lost due to human causes at less than one per year, if the population is going to increase and avoid extinction. The National Marine Fisheries Service has calculated that 3.25 right whales per year either died or were severely injured between 2007 and 2011 by being caught up in fishing gear and lines. The agency estimates that 83 percent of the right whale population shows scarring from fishing gear.

MASSACHUSETTS: Study eyes fish freed from hooks

December 24, 2015 — Researchers at the New England Aquarium, in conjunction with those from state agencies, are getting closer to releasing study results on the collateral impact of recreational haddock discards on the overall mortality rate of the species.

Dr. John Mandelman, director of research at the Boston-based aquarium, said the the field work for the study was completed in early November. He expects the New England Fishery Management Council, which helped fund the study, to complete vetting the analysis sometime early next spring.

The field work was performed with significant assistance from recreational fishing operators such as Gloucester-based Yankee Fleet and Seabrook, New Hampshire-based Eastman’s Docks Fishing Fleet.

“As with all studies, what we very much tried to do was to work as much as possible as part of a legitimate fishing effort, or what we call a fishery-dependent exercise” Mandelman said. “This was a really nice partnership.”

Mandelman said project researchers made about eight trips last spring aboard some of the Yankee Fleet’s larger party boats, focusing on observing how a full range of anglers — from novice to veteran — performed catch-and-release of haddock discards, while also charting catch gear, catch conditions, injuries to the fish, time out of water and sea temperatures.

Fish food for thought: New research affects catch limits

December 21, 2015 — PORTLAND, Maine (AP) — What happens when a fisherman tosses a fish back overboard?

It’s not a frivolous question. The government bases catch quotas and other rules in part on the mortality of tossed fish, and there isn’t always accurate data available about how many fish survive the fling. Now, a group of New England scientists says it’s finding that a surprisingly high percentage of the lucky fish might live to swim another day.

Scientists with the New England Aquarium and other institutions want to help the fishing managers get a better handle on what happens when cod, haddock and cusk get thrown from a fisherman’s line back into the sea. The first round of their research, on the imperiled Gulf of Maine cod, found that 9 to 21 percent of the fish died, better than the 30 percent estimate regulators had been using.

That data could help change quotas for recreational fishermen, who like their commercial counterparts must abide by strict limits on some species.

“We found that mortality rates are pretty low,” Dr. John Mandelman, the New England Aquarium’s director of research and a co-leader of the study. “Generally, in the past, they’ve used really conservative estimates.”

Study: Ropes that break more easily could save some whales

December 15, 2015 — BOSTON (AP) — A study published in a scientific journal says life-threatening whale entanglements could be reduced by using ropes that break more easily under the force of the enormous animals.

Whales become entangled in commercial fishing gear almost every week along the East Coast of the United States and Canada. A coastal study in conservation biology examined ropes retrieved from live and dead whales entangled in fishing gear from 1994 to 2010.

Rare North Atlantic right whale spotted off Gloucester, Mass.

December 1, 2015 — GLOUCESTER, Mass. — Lucky Gloucester residents got a rare glimpse of a North Atlantic right whale this week within 300 feet of the city’s rocky shoreline.

The whale sighted Sunday morning is one of only about 500 North Atlantic right whales left in existence, and though the animals regularly swim along the coast, they are seldom seen.

Researchers have confirmed that the whale spotted off Gloucester was a right whale.

“It’s one of the rarest individuals in the world, so to have this sighting is special,” said Amy Knowlton, a research scientist at the New England Aquarium. “They were hunted nearly to extinction … and they really have not recovered very quickly.”

The aquatic mammals feed on copecods, crustaceans that are abundant on Jeffreys Ledge, about 20 miles northeast of Gloucester, according to Tim Cole, a biologist with the National Oceanic and Atmospheric Administration’s Fisheries Science Center in Woods Hole.

GLOUCESTER DAILY TIMES: Loss of Research Center a Blow to Gloucester

September 29, 2015 — GLOUCESTER, Mass. — It is difficult to think of the departure of the Large Pelagics Research Center as anything less than a great loss for Gloucester.

Officials from the facility, associated with the University of Massachusetts at Amherst since 2010, announced earlier this week that the center will move from Hodgkins Cove to Boston, and change its affiliation within the university system.

The research center will join UMass Boston’s School for the Environment, allowing founder and director Molly Lutcavage to work with researchers from that school as well as those from the New England Aquarium.

“It’s kind of like starting over again,” Lutcavage told reporter Sean Horgan. “But it’s a really exciting time and we’re really looking forward to working with an incredible cross-section of ocean and research scientists within the School for the Environment. This is really exciting for us to be affiliated with them.”
