Scientists, fishermen plot ways to prevent whale entanglements

May 25, 2016 — PORTSMOUTH, N.H. — Nette Leverman was reading from a sheaf of papers she held in her hand, detailing the interactions between whales and fishermen in Greenland, where she is a population biologist.

Humpback, minke, fin and bowhead whales were getting caught in fishing line and nets in the waters off the country’s coast. It’s a familiar refrain, heard over and over Monday, the first day of a four-day international workshop on large whale entanglements.

“We’ve known for decades about this problem, yet solutions to it remain elusive,” said Tim Werner, a senior scientist at the New England Aquarium, and one of the workshop’s organizers.

Governments and fishermen around the world are feeling the strain from an increasing numbers of whales being snared in fishing gear as some whale species rebound and as the amount of gear in the water increases for fishing, aquaculture and other uses.

NOAA Fisheries Hosts Thorny Skate Extinction Risk Workshop

May 10, 2016 — The following was released by NOAA:

NOAA Fisheries is hosting a Thorny Skate Extinction Risk Workshop to discuss the threats to thorny skates and their risk of extinction.

We are currently evaluating whether thorny skates should be listed under the Endangered Species Act.

Where: Maritime Gloucester, 23 Harbor Loop Road, Gloucester, MA.

When: May 19 from 9 a.m. to 4 p.m.

Goals and objectives:

An extinction risk analysis (ERA) can be used to help evaluate the known or perceived risk to the continued persistence of a species. At the ERA Workshop, participants will review and discuss the information on the threats to thorny skate (Amblyraja radiata) noted in the petition and in the literature, available data sets and models regarding status; and types of ERAs that have been used for other species. A summary of the workshop will be prepared for use by the ERA working group and NOAA Fisheries.

Following the workshop, an ERA working group comprised of invited participants with expertise in thorny skates or other elasmobranchs will review data and analysis on thorny skates and select a method to use to develop an extinction risk assessment for the species. Following the discussion and results of the extinction risk assessment, the ERA working group will document their individual expert opinions and findings related to extinction risk for the species in a report. Both the workshop summary and the ERA working group’s report will be independently peer reviewed and will be used to help inform the listing determination for the species.

Invited Expert Participant Selection Criteria:

Invited working group participants were identified based on their working knowledge and recent experience with one or more of the following: 1) expertise in extinction risk analysis and/or population modeling; and/or 2) expertise in fisheries population dynamics, stock assessments and life history of elasmobranchs; and/or 3) advanced working knowledge of and recent experience developing and running population models with the available thorny skate data. 

Working Group Invited Expert Participants:

  • Tobey Curtis- Greater Atlantic Regional Office
  • Sonja Fordham- Shark Advocates International
  • Jon Hare- Northeast Fisheries Science Center
  • Fiona Hogan- New England Fisheries Management Council
  • John Mandelman- New England Aquarium

Helping Fishermen Catch What They Want, and Nothing Else

May 3, 2016 — Heather Goldstone, of NPR affiliates WGBH and WCAI, discusses bycatch reduction in fisheries on a recent episode of “Living Lab.” Her guests were veteran gear designer Ron Smolowitz of the Coonamessett Farm Foundation, who has worked with the southern New England scallop industry; Steve Eayrs, a research scientist at Gulf of Maine Research Institute, who has worked with groundfishermen in Maine; and Tim Werner, a senior scientist with the New England Aquarium, who put acoustic pingers on gill nets to warn away dolphins. An excerpt from the segment is reproduced below:

It’s the holy grail of commercial fishing: catch just the right amount of just the right size of just the right species, without damage to the physical environment. It’s a tall order, and few fisheries are there yet.

Leaving aside the issue of straight up over-fishing, the Food and Agriculture Organization of the United Nations estimates that, each year, fishermen around the world accidentally catch more than seven million tons of marine life – everything from whales and turtles, to sea cucumbers – that they weren’t even after. Such by-catch, as it’s known, is essentially collateral damage.

And fishing has other environmental impacts. In some parts of the ocean, the scars left by trawls dragged across the sea floor can be seen for years.

But, it doesn’t have to be that way. Over the past decade or so, a lot of effort has gone into designing fishing gear and related equipment that allows fishermen to catch more of what they do want, and less of what they don’t, while also minimizing damage to the environment. For example:

  • Veteran gear designer Ron Smolowitz and the Coonamessett Farm Foundation have worked with the southern New England scallop industry over the past several years to develop a trawl that excludes loggerhead sea turtles. It turns out, it’s also better at capturing scallops, with the end result that scallopers can use smaller areas and less fuel – 75% less – to make their catch.

Scientists say more cod might survive fishing than thought

April 22, 2016 — BIDDEFORD, Maine — A group of scientists say more Atlantic cod might survive being thrown back in the water by fishermen than previously thought.

Scientists from several organizations, including the New England Aquarium in Boston and University of New England in Biddeford, conducted a study. It’s published in the International Council for the Exploration of the Sea’s Journal of Marine Science.

Right Whale, Wrong Place

April 20, 2016 — Whale watchers spent the day yesterday in Nahant looking for Mr. Right.

A wayward North Atlantic right whale made a splash just off the shore for most of the afternoon.

The endangered species is known to hang out near Cape Cod Bay this time of year, according to Charles “Stormy” Mayo, senior scientist at the Center for Coastal Studies in Cape Cod and director of the right whale ecology program.

“Anytime a few whales go up the shore it’s really a special thing and a rare occasion,” he said. 
“Every time, in the case of the right whales, their travel depends on the concentration of food; they’re grazers.”

Mayo added he thinks the whale frolicking off Nahant is likely to return to the Cape, where there is the highest concentration of North Atlantic right whales. Fewer than 500 are thought to exist.

At-sea monitoring fees are the latest threat to New Hampshire’s dwindling fishing industry

April 1, 2016 — Working as both a biologist and a fisherman, David Goethel brings a unique perspective to the state and federal fishery management boards he’s an adviser on. 

“I’ve spent all my life acting as a translator because they speak all different languages,” says Goethel, who worked as a research biologist at the New England Aquarium before he became the owner and operator of the Ellen Diane, a 44-foot fishing trawler based out of Hampton. 

But the most recent disconnect between the factions has resulted in Goethel and other groundfishermen filing a federal lawsuit. 

After delaying the regulation for years, the National Oceanic and Atmospheric Administration is now requiring groundfishermen to pay for the at-sea monitoring program — at a cost of an average $710 per trip, conducted at random. The monitoring is done to ensure that the fishermen adhere to groundfish catch quotas set in May 2010 by the New England Fishery Management Council, under NOAA. (Groundfish include cod, haddock and other common bottom-dwelling species.)

Environmental groups release scientific analysis of areas proposed for Atlantic marine monuments

March 29, 2016 – WASHINGTON (Saving Seafood) – This morning, the “Protect New England’s Ocean Treasures Coalition” released an analysis of Northeast ocean areas under consideration for designation as marine National Monuments. The analysis was conducted by Dr. Peter Auster of Mystic Aquarium and Dr. Scott Kraus of the New England Aquarium, and was presented in a press webinar organized by the Pew Charitable Trusts.

Dr. Auster and Dr. Kraus concluded, among other findings, that the proposed monument areas possess high habitat diversity and an abundance of species, function as a source of habitats including for commercial species, and contain species sensitive to disturbance. However, they noted that they do not have adequate data to address what the economic and human effects of area closures to fisheries might be. Presenters also acknowledged that the areas under consideration are already protected, but expressed concern about the future possibility of drilling and mining.

A monument designation would likely affect the fisheries for Atlantic red crab, offshore lobster, squid, mackerel, butterfish, tilefish, albacore wahoo, dolphinfish (mahi mahi), and others. Pelagic longline, rod and reel, and greenstick fisheries including yellowfin tuna, bluefin tuna, bigeye tuna, and swordfish may also be affected. During the webinar, the presenters conceded that they do not have enough data to analyze how a monument designation would affect many of these fisheries.

The analysis addressed both Cashes Ledge and the Northeast Seamounts and Canyons. White House officials stated last week that Cashes Ledge is “not under consideration for a [national monument] designation at this time.” However, representatives of the Northeast Seafood Coalition and Associated Fisheries of Maine, who attended meetings with White House officials, said in a joint statement that offshore canyon areas east of Cape Cod remain under consideration and “affected fishermen should remain vigilant in assuring that any concerns they may have are addressed.”

The Protect New England’s Ocean Treasures Coalition, which “is advocating for the establishment of a Marine National Monument in the North Atlantic Ocean,” is composed of:

  • Center for American Progress
  • Conservation Law Foundation
  • Environment America
  • Mystic Aquarium
  • National Geographic Society
  • National Wildlife Federation
  • Natural Resources Defense Council
  • New England Aquarium
  • Ocean Conservancy
  • Oceana
  • The Pew Charitable Trusts

Topographic roughness – essentially, small-scale bumpiness of the seafloor – is linked to the distribution and diversity of microhabitats that in turn support a diversity of species. Warmer colors indicate greater "roughness" and are linked to locations of species-rich communities. For example, the area of high roughness on the top of Cashes Ledge (right inside the proposed monument boundary) is where the kelp forest is located and a species diversity hotspot.

Gloucester Daily Times: Right whale population continues to rebound

March 15, 2016 — Here’s a bit of good news about the ocean environment: Right whales, once thought to be on the brink of extinction, are returning to Cape Cod Bay in record numbers.

And it’s not a one-time event. Marine scientists say nearly half of the estimated right whale population of 500 has been spotted in the bay over the past few years. It’s a huge leap from years past, when researchers counted themselves fortunate to see more than a couple dozen visiting the bay in search of food.

“It’s rather extraordinary and somewhat mind-blowing,” Charles “Stormy” Mayo, a senior scientist and director of right whale ecology at the Center for Coastal Studies in Provincetown told the Associated Press.

“There has been a huge pulse in numbers in the past few years,” said Amy Knowlton, a scientist with the New England Aquarium’s Right Whale Research Project.

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.
