MASSACHUSETTS: Panel: Ocean acidification threatens lucrative shellfish sector

February 10, 2021 — As a result of climate change and direct human factors, the waters of the Atlantic Ocean off Massachusetts are becoming more acidic, making them a less friendly habitat for the shellfish that drive a key industry here.

With no action, many of the scallops, clams, mollusks and lobsters at the bottom of the ocean in the Gulf of Maine will begin to dissolve by 2060 and new ones will struggle to form, imperiling an industry that supports thousands of people in the Bay State, a special commission said in a report Tuesday.

The Special Legislative Commission on Ocean Acidification recommended that Massachusetts establish a broad ocean acidification monitoring system and funnel more money into existing programs that address some of the things that are making the ocean more acidic, like residential and agricultural runoff, septic discharges and the deterioration of natural wetlands.

“Ocean acidification poses a serious threat to the Massachusetts state economy, and a potentially existential threat to coastal economies that rely heavily on shellfishing,” the commission wrote in the conclusions of its report. “Massachusetts should act to combat ocean acidification now, rather than later. Ocean acidification is expected to worsen significantly before the end of the century. Actions taken now will ultimately be more cost-effective and valuable than actions taken when significant damage has already occurred.”

Global carbon dioxide emissions absorbed by the ocean and nutrient pollution of waterways drive the pH level of areas of the ocean down, making the waters more acidic and limiting certain ions that help clams, oysters, scallops, mussels and lobsters form their protective shells.

Maine Startup Aims To Pull Carbon Out Of The Atmosphere By Growing — And Then Sinking — Kelp Farms

February 10, 2021 — The fight against climate change has long focused on scaling back humanity’s emissions of planet-warming carbon-dioxide. But a movement is growing to think bigger and find ways to actually pull existing CO2 out of the air and lock it up somewhere safe.

One Maine startup has an innovative approach that’s drawing attention from scientists and investors: grow massive amounts of seaweed and then bury it at the bottom of the deepest sea, where it will sequester carbon for thousands of years.

On a fishing boat a few miles out in the Gulf of Maine, Capt. Rob Odlin and Adam Rich are tossing buoys into the water. Each is tethered to a rope entwined with tiny seeds of kelp, a fast-growing seaweed.

“We’re just fishing for carbon now, and kelp’s the net,” Odlin says.

Gathering data will help manage our coastal resources

February 4, 2021 — Resource management is a tricky thing. That’s especially true in the marine environment where things are so interconnected. Nutrients literally float from one area to the next and the larvae of spawning sea creatures similarly drift from place to place. Marine species do not abide by borders but are instead are a part of a larger ecosystem where things literally flow from one location to another.

For this reason, there are few marine species that are managed at a municipal level. Some, like lobster, are managed by the state – by Maine’s Department of Marine Resources. The DMR has jurisdiction over subtidal waters (those below mean low water) throughout the state. Others, like stripers, are managed by interstate groups like the Atlantic States Marine Fisheries Council. And others, like cod and haddock, are managed regionally by bodies like the New England Fisheries Management Council. They have jurisdiction over waters beyond three miles from shore classified as federal water.

So, what does that leave for the municipalities? That’s a seemingly tiny sliver of intertidal coast. But, this sliver often isn’t tiny at all. It is shallow and broad and supports a valuable array of shellfish species like soft shell, hard shell, and razor clams. While these species do move around as larvae, they are more likely to stay put than other more mobile creatures. For that reason, these are the resources that each town is in charge of managing under a system called co-management. This means that towns work with the DMR who helps to classify areas that are safe for harvesting in terms of water quality and also helps with enforcing statewide regulations.

Pause new offshore wind projects to protect fishing industry, Maine Gov. Mills says

February 3, 2021 — As Maine pursues the nation’s first offshore wind research array in federal waters, Gov. Janet Mills is trying to ease the concerns of the state’s commercial fishing industry.

In a letter to commercial fishermen, Mills said she will ask the state Legislature for a 10-year moratorium on the development of new offshore wind projects in waters managed by the state.

Mills said the efforts are aimed at protecting fishing and recreational opportunities within the three miles of the state’s coastline, which she said are more heavily fished than federal waters.

“Offshore wind is a significant clean energy and economic opportunity for Maine, which we will pursue responsibly, transparently and in consultation with our fishing and maritime industries,” Mills said in a statement. “By focusing on floating offshore technology deep in the Gulf of Maine where the wind is strongest, we will protect Maine’s maritime heritage and coastal economy while being out front in this new competitive industry.”

Black sea bass more abundant in Long Island Sound as water warms

January 29, 2021 — Scientists at the Northeast Fisheries Science Center’s Milford Laboratory in Connecticut documented a distinct shift in Long Island Sound fish abundance, with black sea bass showing up in increasing numbers while winter flounder declined.

The findings recently published in Fishery Bulletin are another confirmation of the steady spread northward of black sea bass – now extending into the Gulf of Maine – as waters warm off the Northeast coast.

According to a narrative issued Thursday by the National Marine Fisheries Service, two warm-adapted species: black sea bass, a commercially and recreationally important fish, and oyster toadfish became more abundant in recent samples.

Oyster toadfish prefer rocky habitats and are not often captured by trawl surveys. Meanwhile, cold-adapted species, including cunner and grubby, declined in numbers over the course of the study.

Winter flounder, also a commercial species, and rock gunnel were notably absent in more recent years. Long-term trawl data collected by the Connecticut Department of Energy and Environmental Protection suggests winter flounder abundance has been declining in the Sound for 20 years. The scientists found no consistent trend in the abundance of tautog and scup, two temperate residents of Long Island Sound. The species are often captured on video by our GoPro Aquaculture Project.

Maine fishing groups remain skeptical of offshore wind plans

January 27, 2021 — Members of the fishing industry in Maine said they remain skeptical of plans to develop offshore wind in the Gulf of Maine in the wake of a moratorium proposed by the state’s governor.

Gov. Janet Mills, a Democrat who supports offshore wind, has proposed a 10-year moratorium on offshore wind projects in state waters. She also pledged Monday to continue involving members of the fishing industry in plans for offshore wind off Maine.

Mills’s announcement comes as the state is working with New England Aqua Ventus on a project that would be the first floating offshore wind research array in the country.

MAINE: Janet Mills proposes offshore wind moratorium to quell fisheries concerns

January 26, 2021 — Gov. Janet Mills on Monday proposed a 10-year moratorium on new offshore wind projects in state-managed waters and other actions aimed at calming concerns among the fishing industry about her plan to create the nation’s first floating offshore wind research farm in the Gulf of Maine.

In a letter Friday to licensed commercial fishermen, the Democratic governor said she would propose the moratorium to the Legislature. It would protect fishing and recreational areas within three miles of coastal waters managed by the state, which she said are more heavily fished than federal waters. She also has directed her energy office to review offshore wind regulations, asking for input from fishermen about the site of the proposed array.

The research array, announced in November, is part of an ongoing offshore wind initiative announced in 2019 by Mills, who has made climate one of her main issues since being elected more than two years ago. A report from her office last November touted offshore wind as a significant opportunity for economic recovery from the coronavirus-induced recession. Mills did not provide a timeline for the project, but the state’s climate goals are to move to 80 percent renewable energy by 2030 and 100 percent by 2050.

MAINE: Offshore wind project raises questions for lobstermen

January 19, 2021 — A Gulf of Maine offshore wind power initiative Maine Governor Janet Mills rolled out late last year has raised concern in the lobster fishing community, with Maine Lobstermen’s Association Executive Director Patrice McCarron telling The American that “the area identified by the state of Maine for a potential offshore wind farm is prime fishing bottom for Maine fishermen.”

Mills first announced plans to explore offshore wind development last June, when she signed a bill requiring the Public Utilities Commission to approve a floating offshore wind demonstration project, the first of its kind in the United States. The program, Aqua Ventus, is run through the University of Maine and is funded through $39.9 million in federal grants from the U.S. Department of Energy.

At the same time, Mills formed the Maine Offshore Wind Initiative, a state-based initiative “to identify opportunities for offshore wind development in the Gulf of Maine and to determine how Maine can best position itself to benefit from future offshore wind projects,” according to a press release.

More information was released in November. The offshore wind research array would be sited 20 to 40 miles offshore into the Gulf of Maine at a yet-to-be-determined site, where the dozen or fewer floating wind turbines would cover about 16 square miles of ocean. Maine is filing an application with the Bureau of Ocean Energy Management, as the array will be farther than 3 miles off the coast in federal waters. According to a Nov. 20 press release, the technology for floating arrays is still being developed, and their effect on marine life and fisheries requires further study.

The science of sustainable seafood, explained

January 13, 2021 — The following was released by Sustainable Fisheries UW:

Commercial fishing is vital to global food production. Wild-caught fish contain every essential amino acid, require no land or freshwater, and are a renewable resource when managed sustainably. In addition to providing access to healthy, low-impact protein, the seafood industry is worth over a trillion dollars annually and employs 40 million people—ensuring its sustainability is vital to economies all over the world. We explain seafood industry regulations in our section on fishery management—but first, the fundamental key to understanding sustainable seafood is grasping the science of catching fish.

Fisheries are composed of fish stocks and the fishing fleet that catches them. A fish stock is simply a harvested population. It refers to one specific species in one particular place, like Gulf of Maine cod. A fishery is the intersection of a stock (or group of stocks) and the means of harvest. Fishing fleets can use several different methods to capture fish, each method describes the fishery and guides management.

A fishery is sustainable when the amount harvested does not compromise future harvests.

Fishery science is the process that answers that question, primarily through stock assessments. A stock assessment uses several different kinds of data to understand the health of a stock and determine how much can be fished. You can think of the data as the A,B,Cs of stock assessments – abundance, biology, and catch.

  • Abundance is how many fish are in the population; estimates of abundance are made based on samples that are gathered using various methods.
  • Sampling can also collect biological data such as: age and length from which we can estimate levels of natural mortality and fishing mortality. Together, these data help estimate the reproductive rate of a population, which in turn allows us to predict how many fish will be around next year.
    • During sampling, environmental data like temperature, salinity, dissolved oxygen and other ecological variables are also collected.
  • Catch data are our historical records of how many or what weight of fish was caught during a calendar year or a fishing season.

Fall Gulf of Maine Bottom Longline Survey Wraps Up

January 7, 2021 — The following was released by NOAA Fisheries:

The COVID-19 pandemic and typical fall weather conditions were challenges, but the Cooperative Gulf of Maine Bottom Longline Survey team and industry partners wrapped up a successful season in early November.

“Every single person on the bottom longline survey team worked incredibly hard to get the survey completed this fall,” said Anna Mercer, chief of the Cooperative Research Branch. “From building new software to installing new camera systems, from repeated COVID-19 testing to careful quarantining, from new work flows to new hardware, it was a true team effort.”

The survey targets groundfish at 45 stations across the Gulf of Maine using tub-trawl bottom longline gear. The survey plan focuses on rocky bottom habitat, where fish are difficult to sample with trawl gear.

New Data Collection System Used

This year’s survey is the first to use a new data collection system developed by the branch. This next generation of software and hardware significantly upgrades digital data collection and catch processing at sea.

A tablet-based application replaces paper logs for most data types, improves operational efficiency, consistency, and data quality control for recording catch data and biological samples. Digital scales, electronic fish measuring boards, and barcode scanners now wirelessly communicate with the tablets. This keeps the system compact and agile for use on small commercial fishing vessels.

Both vessels were also newly equipped with electronic monitoring cameras. Adding cameras provides a way to get detailed information on the condition of bait or fish on hooks as the vessel retrieves the gear. This “hook status” information gives analysts a measure of hook availability—how available the hook is to fish that the gear encounters—which will improve understanding of catch rates.
