Saving Seafood

MARYLAND: How can we save oysters if we harvest them faster than they reproduce?

March 27, 2019 — This year’s Maryland General Assembly session marks a critical juncture for Chesapeake Bay oysters. Policies under debate in the halls of the legislature will chart the course for oysters’ next 100 years. Now is the time to make the changes necessary to protect the oyster.

Before the session, the bad news arrived. In November, the state released the first comprehensive stock assessment of Maryland oysters. It found that the bivalves’ population had declined by half since 1999 — from about 600 million adult oysters to the current population of 300 million. The population decline is bad for both the Bay’s ecology and for the watermen who depend on the wild harvest to make their living.

The oyster’s significant decline is a symptom of a long history of overharvesting, disease and pollution in the Bay. The current population of oysters in Maryland’s portion of the Bay is less than 10 percent of the number of oysters harvested each year before 1900, according to the stock assessment.

While we can’t expect to re-create the natural state of the Bay before significant human intervention, Maryland can’t continue with business as usual. To reduce Bay pollutants, create more habitat for fish species and preserve the oyster for future generations, we must put Maryland on a path toward oyster recovery.

Study maps where tunas, sharks and fishing ships meet

March 26, 2019 — Overfishing is rapidly pushing many of the world’s sharks and tunas toward extinction. The world’s fastest known shark, the shortfin mako, for example, was recently uplisted to endangered on the IUCN Red List, its decline mostly attributed to overfishing.

But researchers are only beginning to figure out where and when people fish them the most. Now, a new study has some answers.

By analyzing the trails of more than 900 fishing vessels and more than 800 sharks and tunas in the northeast Pacific, researchers have identified regions where the two tend to overlap. This information, researchers say, can be used to manage fisheries, especially in the high seas, the swaths of ocean that lie beyond the jurisdiction of individual countries.

“These fish [sharks and tunas] may travel thousands of miles every year, crossing international boundaries and management jurisdictions,” said Timothy White, lead author of the study and a graduate student in biology at Stanford University, California. “In order to sustainably manage them, we need to know where they migrate and where people fish them, but this info is surprisingly difficult to gather for sharks and tunas of the open ocean.”

Striped bass population in trouble, new study finds

February 8, 2019 — Striped bass, one of the most prized species in the Chesapeake Bay and along the Atlantic Coast, are being overfished according to a new assessment of the stock’s health — a finding that will likely trigger catch reductions for a species long touted as a fisheries management success.

The bleak preliminary findings of the assessment were presented to the Atlantic States Marine Fisheries Commission, a panel of fisheries managers, on Wednesday. The full analysis was not available. Its completion was delayed by the partial government shutdown, which sidelined biologists in the National Marine Fisheries Service who were working to complete the report.

But, noted Mike Armstrong of the Massachusetts Division of Marine Fisheries, who also chairs the ASMFC’s Striped Bass Management Board, the final results “will likely be the same when [the report] comes out.”

The board asked its technical advisers to estimate the level of catch reductions needed to bring the stock above management targets at its May meeting, when the stock assessment is expected to be ready for approval.

“We know it is going to be pretty drastic,” said John Clark of the Delaware Division of Fish and Wildlife, a member of the board.

The findings of the assessment were a bit of a surprise. Though the overall population was known to be declining, striped bass are often considered a signature success for fishery management.

The overharvest of striped bass, also called rockfish, sent their population to critically low levels in the early 1980s, eventually leading to a catch moratorium. The population rebounded, allowing catches to resume, and by 1997 the population recovered to an estimated 419 million fish aged one year or more.

NOAA Fisheries Adjusts the Atlantic Herring Specifications for 2019

February 7, 2019 — The following was released by NOAA Fisheries:

Today, we are adjusting Atlantic herring specifications for 2019. This in-season adjustment reduces 2018 Atlantic herring specifications and sub-annual catch limits (ACLs) for 2019 to prevent overfishing and lower the risk of the stock becoming overfished. All other Atlantic herring specifications, including river herring and shad catch caps, remain unchanged from 2018.

The 2018 Atlantic herring stock assessment concluded that while Atlantic herring was not overfished and overfishing was not occurring in 2017, Atlantic herring catch would need to be reduced to prevent overfishing and lower the risk of the stock becoming overfished.

At its September 2018 meeting, the New England Fishery Management Council requested we use an in-season adjustment to reduce Atlantic herring catch limits for 2019 to prevent overfishing. We published a proposed rule in November 2018. The herring acceptable biological catch (ABC) we proposed for 2019, as well as the resulting ACL and sub-ACLs, while consistent with methods used to set recent specifications, were higher than limits recommended by the Council.

The Council reviewed our proposed Atlantic herring catch limits for 2019 at its December 2018 meeting and recommended that we further reduce herring catch limits to better account for scientific uncertainty and achieve conservation and management objectives. For these reasons, we are reducing the herring specifications and sub-ACLs for 2019 consistent with the Council’s recommendations.

For more information read the rule as filed in the Federal Register and posted on our website.

ASMFC Summer Flounder, Scup and Black Sea Bass Board Approves Status Quo Measures for 2019 Recreational Black Sea Bass Fishery

February 7, 2019 — The following was released by the Atlantic States Marine Fisheries Commission:

The Atlantic States Marine Fisheries Commission’s Summer Flounder, Scup and Black Sea Bass Management Board approved status quo measures for the 2019 black sea bass recreational fishery (see Table 1). This action is based on the recommendations of its Technical Committee, which found that status quo measures are not likely to exceed the coastwide recreational harvest limit for 2019. Based on the most recent most stock assessment, the stock is estimated to be above the biomass target and not experiencing overfishing.

The Board also approved proposals from Virginia and North Carolina to participate in the February 2019 recreational fishery specified by NOAA Fisheries. The season will be open from February 1-28, 2019 with a 12.5 inch minimum size limit and 15 fish possession limit. To account for any harvest in February, Virginia and North Carolina will adjust their management measures later in the season, if necessary. Recreational anglers should verify regulations with their respective states.

We’re accidentally driving this extremely ugly fish to extinction

January 14, 2019 — The Atlantic wolffish is not an attractive beast.

Its appearance is characterized by its large, fang-like teeth (where it earns its name), which are used to crush prey like crabs, lobsters and sea urchins. Its throat is also peppered with more serrated teeth.

It may come as a surprise then to hear that their numbers have dwindled relentlessly over the last century partly as a result of overfishing.

  • In the US, catches of Atlantic wolffish declined from over 1,200 tons per year to around 30 tons per year between the 1980s and the 2000s.
  • In the UK, wolffish have declined in English and Welsh trawl fisheries by 96% since 1889.
  • In the Baltics, the fish’s population has been classed as endangered, meaning it has a high risk of extinction in the wild.

But we don’t eat them. So why are they being overfished to the point of extinction?

For decades, scientists thought sturgeon had vanished from Maryland waters. They’re delighted to be wrong

January 3, 2019 — When David Secor started his career at the Chesapeake Biological Laboratory almost three decades ago, one of his first projects concluded that the Atlantic sturgeon had all but disappeared from polluted Maryland waters.

The population of the massive fish — often 14 feet long — that once swam with dinosaurs plummeted in the 1900s amid rising demand for their eggs, better known as caviar. Overfishing devastated the species for the same reason caviar is such an expensive delicacy: Sturgeon roe is scarce because females don’t produce it until they’re at least 9 or 10 years old. Even then, the fish don’t spawn every year.

So Secor and other biologists were shocked and then intrigued when, over the past decade, watermen and recreational fishermen started spotting what looked unmistakably like sturgeon flopping and splashing around the Nanticoke River on Maryland’s Eastern Shore. One even landed on the deck of a fisherman’s boat.

Mislabeling Food in Peru Stirs Overfishing Worries

December 27, 2018 — In Peru, ceviche is not just the national dish but also a way of life.

The country may be best known for its Inca heritage but it is also a fishing superpower while its acclaimed culinary renaissance is arguably a greater source of local pride than Machu Picchu.

Even high in the Andes, residents are accustomed to lunching on the marinated seafood salad made with fresh fish trucked straight up from the Pacific Coast.

But what may shock Peruvians is learning that due to mislabeling they are unwittingly consuming endangered shark species. According to Juan Carlos Riveros, science director for the Peruvian arm of the international marine conservation nonprofit Oceana, 8 in 10 customers here fall for the misleading practice.

A recent DNA study by nonprofits Oceana and ProDelphinius found that 43 percent of the 450 samples taken from fish in Peruvian restaurants, supermarkets and fishing terminals were mislabeled. The reason for that is simple, conservationists say; the number of fish in Peru’s heavily exploited waters is dwindling. Sometimes inadvertent and sometimes deliberate, mislabeling a catch is always ecologically damaging given the dramatic and unsustainable fall in shark populations around the world.

Why the battle to fix Europe’s fisheries policy isn’t over yet

December 20, 2018 — Overfishing in EU waters, and the wasteful practice of discarding edible fish at sea, should come to an end from next year, as reforms to the common fisheries policy (CFP) are implemented after seven years of wrangling.

But disputes among member states over rights to dwindling fish stocks mean that key aspects of the plans to improve management of European fisheries are floundering.

From January, the landing obligation should mean that all fish netted are brought to shore instead of thrown away if they exceed a vessel’s quota. By 2020, all stocks should be subject to quotas based on scientific judgments of the maximum sustainable yield, not annual horse-trading among politicians.

However, as fisheries ministers met in Brussels for quota negotiations on Wednesday, it was clear these long-promised reforms would not be implemented in the way campaigners had hoped. Also, there were signs that the UK would face more difficult negotiations after Brexit, as shared waters make up most of the productive seas fished by UK fleets.

The European commission is struggling to insist on the discard ban, against the wishes of some member states. A spokesman said: “The commission has put forward concrete solutions to advance on sustainable fishing and to ease the implementation of the landing obligation, but we cannot do it without the support of the member states.”

NGO finds EU countries could catch 56% more fish if ministers stop Atlantic overfishing

December 19, 2018 — Research undertaken by the NGO Oceana shows Denmark, France and the UK would ultimately register the highest increases in catch volume if EU ministers follow scientific advice when they meet to set the new 2019 quotas on Dec. 18.

The EU could increase the volume of fish landings from the North-Eastern Atlantic and the North Sea by 56%, up to more than 5 million metric tons, according to a study by Oceana.

The organization found that the recovery would take less than ten years, and that Denmark, France, the UK, Netherlands and Spain would benefit the most if scientific advice was followed. Ministers are under pressure in the approach to 2020, whereby under the common fisheries policy, all total allowable catches must be set sustainably.

Lasse Gustavsson, executive director of Oceana Europe, implored EU ministers to think of the longer-term benefits over short-term gains.
