Saving Seafood

More management measures lead to healthier fish populations

January 12, 2021 — The study, led by Michael Melnychuk of the University of Washington’s School of Aquatic and Fishery Sciences, draws upon the expertise of more than two dozen researchers from 17 regions around the world. The research team analyzed the management practices of nearly 300 fish populations to tease out patterns that lead to healthier fisheries across different locations. Their findings confirmed, through extensive data analysis, what many researchers have argued for several years.

“In general, we found that more management attention devoted to fisheries is leading to better outcomes for fish and shellfish populations,” Melnychuk said. “While this won’t be surprising to some, the novelty of this work was in assembling the data required and then using statistical tools to reveal this pattern across hundreds of marine populations.”

The research team used an international database that is the go-to scientific resource on the status of more than 600 individual fish populations They chose to analyze 288 populations that generally are of value economically and represent a diversity of species and regions. They then looked over time at each fish population’s management practices and were able to draw these conclusions:

  • In regions of the world where fish and shellfish populations are well studied, overall fisheries management intensity has steadily increased over the past half century
  • As fisheries management measures are implemented, fishing pressure is usually reduced toward sustainable levels, and population abundance usually increases toward healthy targets
  • If fish populations become depleted as a result of overfishing, a rebuilding plan may be implemented. These plans tend to immediately decrease fishing pressure and allow populations to recover
  • If strong fisheries management systems are put in place early enough, then overfishing can be avoided and large, sustainable catches can be harvested annually, rendering emergency measures like rebuilding plans unnecessary

In Scotland, the battle for scallops and the future of sustainable fisheries

January 4, 2021 — People enjoy scallops in Oban. “We can’t get enough of them to satisfy demand,” smiles Carol Watt, whose family business has been selling fish for more than a century in the port city of Argyll.

Watt explains how she likes to cook the mollusks: pan-fried and eaten with pancetta, Italian bacon, as a line of masked shoppers forms outside her tiny mustard-yellow shack.

Watt beams with excitement as she shows off a tray of shucked scallops, palm-sized, pale, fleshy slices with the fiery red roe still holding on, which some customers find too spicy, wearing an apron emblazoned with a species-rich school of fish.

In the past, scallops, often referred to simply as “clams” in Scotland, were never so common. In 1960, the Scottish ports landed just sixty tons of the species. There were 15,000 tons in 2019, down 2% from 2018 but still worth almost £ 36 million.

The boom, however, has sparked an often bitter conflict about how scallops, which grow on the seabed, are harvested between environmentalists and the fishing industry.

Some “scallops” are lifted from the sea sustainably by divers, who charge a premium for doing so.

If you recently bought Maine seafood online, 2020 might be the reason why

December 16, 2020 — Though 2020 will be remembered for many things, it also may be remembered as the year when online, direct-to-consumer sales of Maine seafood took off.

In a year that saw continued wrangling over foreign trade agreements — which hampered overseas sales of Maine lobster, the state’s dominant seafood product — and a severe drop in restaurant sales due to precautions aimed at containing the spread of COVID-19, many seafood harvesters and producers have sought to connect directly with consumers to stay afloat.

A new marketing initiative launched this month by the state — created with $1 million in COVID-19 federal relief funds — is the latest effort geared toward making it easier for consumers to buy Maine seafood directly from distributors and retailers. A website borne of that initiative, SeafoodfromMaine.com, follows suit with other sites such as Localcatch.org and Lukeslobster.com that aim to connect consumers and sellers directly online, or to guide consumers to retailers that sell locally sourced seafood.

MASSACHUSETTS: Weekend farmers market aims to help local shellfishermen

December 10, 2020 — A first-of-its-kind shellfish farmers market promises to get oysters from Wellfleet Bay to the dinner plate in record time.

Shellfishermen will be able to sell their oysters to customers on Saturdays from noon to 2 p.m. beginning this weekend at the Wellfleet Marina. The market will run through May 1.

The initiative came after a monthlong effort led by the town’s shellfish constable, Nancy Civetta, with assistance from the Wellfleet Shellfishermen’s Association and Holbrook Oyster. Civetta was able to get approvals from the Massachusetts Department of Public Health and Division of Marine Fisheries to hold the event.

New Study Finds Ways to Potentially Reduce Uncertainty in Shellfish Assessments

December 4, 2020 — The following was released by the Science Center for Marine Fisheries:

Researchers working to determine the abundance of shellfish, including surfclams and ocean quahogs, have faced limits in getting a precise count due to the uncertainty inherent in stock assessment surveys. A new study, by Leanne Poussard, Dr. Eric Powell, and Dr. Daniel Hennen and published this month in Fisheries Research, examines one of these sources of uncertainty.

Uncertainty is a major factor affecting all stock assessments, which rely on estimating the size of an entire population based on the data provided by a small sample. Identifying these sources of uncertainty is key to producing precise estimates. In the case of surfclams and other shellfish species, a main driver of uncertainty is how efficient the dredges used during the stock surveys are in catching shellfish.

The National Marine Fisheries Service (NMFS) conducts what are known as depletion experiments to measure how efficiently a dredge harvests clams; a dredge will be run multiple times in a single area, and how quickly the catch declines with each subsequent tow will be used to estimate its efficiency. NMFS has also developed a statistical model to estimate the level of uncertainty present in these experiments.

Using this model, as well as running simulations of dredge tows, the new study finds that uncertainty in depletion experiments can be significantly reduced by taking measures such as running additional tows, and having more overlapping tows during the course of an experiment to measure gear efficiency. Having these measures in place could significantly reduce the role of survey gear as a source of uncertainty.

“By making modest changes to the way we conduct surfclam depletion experiments, we can potentially reduce uncertainty and be more confident in the ultimate results of clam stock assessments,” said Leanne Poussard, the lead author of the study. “This study provides clear guidance on the best ways to conduct future shellfish depletion experiments.”

“As a participant in NMFS surfclam and ocean quahog stock assessments over the past 30 years, I can attest that uncertainty regarding dredge efficiency has been a continuing source of scientific caution in projecting stock biomass, and appropriate levels of commercial harvest,” said Tom Alspach, of Sea Watch International. “This new work should significantly ameliorate that uncertainty, allowing fishery managers to appraise stock sustainability with more confidence, leading in turn to stability in annual quotas for the direct benefit of the harvesting sector. This is why the surfclam/ocean quahog industry has enthusiastically provided financial support for the research initiatives of SCEMFIS.”

The study is the latest to be funded by the Science Center for Marine Fisheries (SCEMFIS), and is part of the Center’s work of improving shellfish science and management. SCEMFIS is part of the National Science Foundation’s Industry-University Cooperative Research Center program. Working together with its partners in the fishing industry, SCEMFIS identifies the most pressing needs in finfish and shellfish science. In the last year, SCEMFIS funded over $191,000 in scientific research.

Additional Public Listening Session on December 3 for Aquaculture Opportunity Areas

November 25, 2020 — The following was released by NOAA Fisheries:

December 3, 2020 from 12 pm to 2 pm ET

Aquaculture Opportunity Areas (AOA), which are called for in the May 2020 Executive Order on Promoting American Seafood Competitiveness and Economic Growth, are defined as geographic areas that have been evaluated for their potential for sustainable commercial aquaculture. Selected areas are expected to support multiple aquaculture farm sites of varying types including finfish, shellfish, seaweed, or some combination of these farm types.

We have added a fifth AOA listening session to grant stakeholders another opportunity to provide comment. To ensure that all stakeholders, including the recreational and commercial fishing industries, from whom we would like to hear more, have the opportunity to provide comments the additional public listening session will be held December 3, 2020 from 12:00-2:00 ET.

Through the current request for information, which is open until December 22, the public and our stakeholders are encouraged to provide comments for AOA creation in federal waters off of southern California and the Gulf of Mexico as well as the location of future AOAs. The synthesis of public input and NOAA’s powerful data-driven siting analysis are essential elements to highlight space that is environmentally, socially, and economically appropriate for commercial aquaculture. We look forward to hearing from you.

Cape Cod’s oyster growers struggle to recover from pandemic losses

October 12, 2020 — When Gov. Charlie Baker shut down restaurants and bars in March, Zack Dixon’s world, and that of hundreds of other shellfish farmers in Barnstable County, dropped off a cliff.

“Restaurants are our customers. When they closed in March, our business revenues went to zero,” said Dixon, who co-owns the Holbrook Oyster company with Justin and Jacob Dalby.

Over the past couple of decades, oysters have become the darling of the culinary world and aquaculture has expanded exponentially. Massachusetts landed nearly 8.7 million pounds of oysters, mostly from aquaculture farming, in 2018, worth $28.3 million. The Cape is home to 265 of the 391 licensed growers in the state, cultivating nearly 661 acres, half the state total of 1,203 acres.

When the East Coast Shellfish Growers Association surveyed larger dealers and wholesalers following the shutdown, they found that 98% of the market for oysters had evaporated overnight, said association president Bob Rheault.

“We knew we were inextricably tied to the food service industry, we didn’t realize how tied in we were,” said Rheault. “I don’t think any one of us would have guessed that amount.”

Maine shellfish farmers gaining confidence with scallops

September 21, 2020 — In Maine, Atlantic sea scallops (Placopecten magellanicus) are one of the most valuable fisheries in U.S. waters, the target of deep-sea draggers and divers on dayboats.

But compared to a seasonal fishery, an aquaculture crop has the key advantage of a year-round supply and steady pricing. In an attempt to build a fledgling scallop farming industry, Maine shellfish farmers started trialling a Japanese technique called ear hanging in 2017. Taking advantage of a sister state agreement with Aomori Prefecture in northern Japan, growers in Maine are working to establish semi-automated commercial aquaculture operations (the Advocate covered these efforts in 2016).

Since then, progress has accelerated. In 2018, community development and business advising firm Coastal Enterprises Inc. (CEI), which has been part of the ear hanging work since 2016, received a grant from the Foundation for Food and Agriculture Research for a three-year program to further develop ear hanging in Maine.

CEI purchased three machines from Mutsu Kaden Tokki Co., Ltd., in Mutsu City, Aomori. Five farms have utilized the equipment implementing small-scale commercial trials with several thousand scallops on each farm, while market research by CEI has been gauging the potential demand for ear-hung farmed scallops.

Project aims to boost Louisiana oyster safety and profits

September 9, 2020 — LSU researchers have launched a project that aims to give Louisiana oyster harvesters a way of detecting whether waters contain viruses or bacteria that can cause some people to get sick when they eat the shellfish raw or undercooked.

“This project is meant to decrease the number of people getting sick and also decrease oyster recalls,” civil and environmental engineering professor Zhiqiang Deng said in a news release. “The project will aid in the economic development of Louisiana by reducing costly oyster ground closures and recalls, thereby increasing oyster production.”

One-third to 40% of the oysters harvested in the U.S. come from Louisiana waters, more than any other state. The industry employs about 4,000 people in the state, with an economic impact of $317 million annually, according to the Louisiana Seafood Promotion & Marketing Board.

About a fifth of all oysters harvested in Louisiana come from the Terrebonne Basin, an area that includes all of Terrebonne and parts of Lafourche and several other parishes between the Acthafalaya River and Bayou Lafourche, state figures show.

MAINE: New England clammers press through pandemic

September 8, 2020 — For New England’s vanishing commercial clam harvesters, the coronavirus pandemic represents only the most recent in a string of setbacks that have held down the centuries-old industry.

The clamdiggers, who pull softshell clams for use in chowders and clambakes from tidal muck, have weathered an aging workforce, relentless predators that eat shellfish, warming waters and fickle markets. This summer’s pandemic has held back few of the clamdiggers from plying their trade in the coastal clam flats that have fed their customers for generations, members of the industry said.

Buyers have rewarded the clammers with prices that have held up better than many sectors of the beleaguered seafood industry, which has suffered a significant economic hit from the pandemic. But some clammers said the disruption wrought by the pandemic has still created yet another difficulty to deal with.

“If they shut down the borders now, like they did before, we’d be in some big trouble. We rely on shipping,” said Wendell Cressey, a Harpswell clammer. “Not only do we need the tourists to be able to come here and visit, but we need to be able to ship them around the country.”
