Deep water sites off the US northeast coast are suitable for offshore blue mussel farms

October 17, 2019 — Offshore mussel farm sites need to have the right temperature, food availability, and the right currents. According to a study by researchers at NOAA’s Northeast Fisheries Science Center, several suitable locations can be found off the Northeastern U.S.

Their findings, published in the Journal of Marine Science and Engineering, suggest that the most promising locations for mussel aquaculture among the six oceanic sites studied are off New York’s Long Island, north of Cape Ann in Massachusetts, and off New Hampshire.

A number of research projects have been conducted in the past few decades at pilot mussel farms in Rhode Island Sound near Martha’s Vineyard, off the Isle of Shoals in New Hampshire, and north of Cape Ann in Massachusetts. Results were encouraging, but no commercial ventures have gone forward.

The authors acknowledge that these waters are busy and already subject to numerous competing and overlapping uses. They argue that finding the optimum locations for farms, where the conditions can support the kind of production that will be profitable, is an essential first step in development. If farms are going to compete with other uses, then managers and entrepreneurs alike need to know as much as possible about the requirements and benefits of offshore shellfish farms — especially when some uses must be excluded so that others may thrive.

Another outside crab species turns up in Maine waters

October 15, 2019 — A scientist with an environmental group says she has found what she believes is the first recorded appearance of a potentially damaging species of crab in Maine waters.

Marissa McMahan of the Massachusetts-based group Manomet said she located the smooth mud crab this month on a research trip. The crabs are typically found south of Cape Cod, Massachusetts. They can pose problems for aquaculture businesses because they prey on young oysters — a species of high economic value that is grown in Maine.

McMahan collected the single specimen, and it’s still alive. She said it’s too early to know how the animal ended up in the New Meadows River in West Bath, but it’s important to monitor for more of them.

A Fishermen’s Perspective on Electronic Reporting

October 15, 2019 — The following was released by NOAA Fisheries:

For 200 days of each of the past 44 years, Tony Borges has been setting out from New Bedford, Massachusetts in search of groundfish, fluke, and squid. That’s roughly 8,800 days for those of you keeping score at home. He started fishing with his father, though Borges says his father tried to dissuade him from being a fisherman. He encouraged Borges to join the U.S. Coast Guard instead.

Nevertheless, in 1977, along with his cousin, aunt, and father, he purchased the brand new FV Sao Paulo. He still owns and operates it today.

For the last seven years, Borges has also been participating in the Northeast Fisheries Science Center’s Study Fleet. As part of this scientific data collection program, he records haul-by-haul catch (kept and discarded) information for all species.

When I met Borges early one morning on the Sao Paulo, he was down in the engine room covered in grease. He was working on his vessel’s first complete overhaul in 40 years!

Fishing rules don’t match industry realities, advocates say

October 11, 2019 — The federal government on Wednesday released data showing that cod stocks in the area remain overfished and are not on target to be rebuilt by 2024. NOAA Fisheries also reported that “overfishing is occurring” among an already-depleted Gulf of Maine Atlantic cod population.

“Abundance is very low, not the way it used to be, so that’s obviously of great concern to us,” Division of Marine Fisheries Director David Pierce told the News Service after participating in “seafood day” activities Thursday to recognize the contributions of the fishing sector and the 90,000 jobs in the seafood industry.

Pierce said he had not yet reviewed the latest federal assessment, but said an industry-based survey and one in the works at the University of Massachusetts Dartmouth will also influence cod quotas for 2021 and 2022.

“It’s a very important assessment. A lot hinges on it,” Pierce said. “The health of the Gulf of Maine groundfish fishery is very dependent on the health of that Gulf of Maine cod stock.”

Calling the report “concerning,” Sen. Bruce Tarr, who represents the fishing port city of Gloucester, told the News Service, “I’m still reading through the details but I think it points to the fact that we should be doing things differently than we are today.”

NOAA Fisheries Seeks Comments on Amendment 8 to the Atlantic Herring Fishery Management Plan

October 10, 2019 — The following was released by NOAA Fisheries:

NOAA Fisheries proposes establishing an Atlantic herring acceptable biological catch (ABC) control rule and prohibiting the use of midwater trawl gear in inshore waters from Canada to Connecticut.

Acceptable Biological Catch

The proposed ABC control rule is intended to ensure sustainable harvest of the Atlantic herring resource and account for Atlantic herring’s role as forage in the ecosystem. The control rule would limit fishing mortality to 80 percent of the fishing mortality rate to support maximum sustainable yield when Atlantic herring biomass is high and restrict fishing even further when biomass is low. The control rule would set Atlantic herring ABC for three years but would allow ABC to vary year-to-year with projected estimates of biomass.

Prohibiting Midwater Trawl Gear Inshore

This amendment would prohibit the use of midwater trawl gear inshore of the 12-nautical mile territorial sea boundary from Canada to Connecticut and inshore of 20 nautical miles off the east coast of Cape Cod (see below).

The proposed inshore midwater trawl restricted area is intended to minimize user group conflict as midwater trawl vessels overlap with other user groups (i.e., commercial fisheries, recreational fisheries, ecotourism) that rely on herring as forage. Moving midwater trawl effort offshore is intended to mitigate potential negative socioeconomic impacts on other user groups resulting from short duration, high volume herring removals by midwater trawl vessels and help ensure herring is available inshore for other users groups and predators of herring.

The proposed inshore restricted area may also have biological benefits if it minimizes catch of river herring and shad, reduces fishing pressure on the inshore component of the herring stock, and helps ensure herring are available to predators.

AquaBounty planning to label GM salmon in the US

October 7, 2019 — AquaBounty is planning to preemptively label its genetically modified salmon in the United States in 2020, a company spokesperson told SeafoodSource soon after Canadian seafood industry executives and NGOs spoke out against the fish.

At the Canadian Seafood Show in Montreal, Quebec, in September, a panel of seafood industry executives and environmental groups said that they do not plan to sell or support AquaBounty’s AquAdvantage salmon in Canada.

MASSACHUSETTS: Lobsters, fish fall victim to low oxygen levels in Cape Cod Bay

October 4, 2019 — Two weeks ago, lobstermen working off Scorton Creek started seeing something they had never experienced. Lobsters, in fact everything in their traps, were coming up dead.

Massachusetts Division of Marine Fisheries senior biologist Robert Glenn started fielding phone calls from puzzled fishermen Sept. 23. The fishermen were worried there might be something in the water that was killing the lobsters, fish, shellfish, even sea worms.

It turns out, it was something missing from the water: oxygen.

For the past two weeks, division researchers and scientists from the Center for Coastal Studies in Provincetown have boarded vessels and taken water samples, gathered temperature data at various depths and measured the amount of oxygen dissolved in the water. Preliminary results from testing on dozens of dead lobsters found nothing toxic in the water that could have killed them, and the focus was on a phenomenon that occurs every year — low oxygen in the layer of water along the ocean bottom, Glenn said.

Federal Regulators Take Heat From Both Sides Of The Right Whale-Gear Debate

October 4, 2019 — Federal fisheries regulators are taking heat from both sides of the debate over protections for the endangered North Atlantic right whale.

The latest salvo comes from a conservation group representing public employees, which says the National Marine Fisheries Service (NMFS) ignored its own scientists when it reopened groundfishing areas that had been closed for decades.

Earlier this year, NMFS reopened 3000 square miles of ocean south of Nantucket to groundfishing, allowing the use of gillnets and rope. The agency said that based on previous regulatory reviews and some more recent scientific articles, it could not find sufficient evidence to conclude that fishing gear alone causes a decline in the health of large whales — and that further review was not necessary.

Conservationists say the agency cherry-picked the evidence.

NOAA answers lobstermen’s critique of whale rules science

October 4, 2019 — NOAA Fisheries released a more detailed response Wednesday to criticisms of the science it used to develop new protections for North Atlantic right whales, refuting or clarifying several points while admitting data collection remains “an ongoing challenge.”

The response was attached to a letter from NOAA assistant administrator Chris Oliver to Patrice McCarron, executive director of the Maine Lobstermen’s Association. In August, the lobster trade group withdrew its support for the right whale protection plan approved in April by the federal Atlantic Large Whale Take Reduction Team.

In its Aug. 30 letter to NOAA Fisheries, the Maine Lobstermen’s Association said it based its defection on its own analysis of the science NOAA utilized in developing the right whale protection plan that points to the lobster industry as a chief cause of whale entanglements.

The MLA said its review concluded that lobster lines and gear are among the least prevalent causes of serious whale injuries or death.
