VIMS coastal shark study shows species recovering from overfishing

March 6, 2017 — The 1975 horror movie “Jaws,” featuring a giant, man-eating shark, turned the ocean into a scary place for swimmers.

It got even scarier for sharks.

In large part because of that blockbuster and its many sequels, sharks were hunted increasingly by recreational and commercial anglers in the ’70s and ’80s, to the point that some species nearly disappeared.

Now, a new analysis of seven coastal shark populations led by the Virginia Institute of Marine Science in Gloucester Point indicates that federal protections enacted in the 1990s have brought most of those species back from the brink.

How Many Sharks Are Left? The Number Of Sharks Is Growing, Decades After ‘Jaws’ Caused Overfishing In The Atlantic Ocean

March 2, 2017 — Sharks took a huge publicity hit when “Jaws” was released in movie theaters, but it looks like the marine animals are finally bouncing back: Six species that had dwindled in number due to Atlantic Ocean overfishing have made population gains, says a new report.

A study in Fish and Fisheries zoned in on seven types of sharks that inhabit waters along the coast of the Atlantic Ocean in North America, and analyzed their numbers between 1975 and 2014. All of the large species “showed similar decreasing patterns into the early 1990s, periods of sustained low index values thereafter and recent indications of recovery.” Although the smaller species did not have as simple a pattern, they are increasing in numbers as well, “suggestive of initial recovery from past exploitation.”

Of all the species investigated, only the blacknose shark from the Gulf of Mexico, a species that grows to about 4.5 feet, did not show a population increase.

The other small species included in the study were the Atlantic sharpnose and the bonnethead sharks. The larger species were the sandbar shark, blacktip shark, spinner shark and tiger shark, which can grow up to 18 feet.

According to the Virginia Institute of Marine Science, overfishing which heavily depleted shark numbers “began in earnest following the release of Jaws in 1975 and continued through the 1980s.”

Pacific Tuna Commission To Assess Shark Survival Rates After Catch And Release

February 22, 2017 — The Western and Central Pacific Fisheries Commission, or Tuna Commission, is launching a study to assess shark survival rates post catch and release.

That follows the meeting of a group of scientists and academics from around the world in Wellington last month at New Zealand’s National Institute of Water and Atmospheric Research.

A spokesperson for the project, Shelley Clarke, said a sample of about 200 sharks in the Pacific will be electronically tagged and tracked.

FLORIDA: Senate Bill Targets Shark Fin Trade

Editor’s note: “Shark finning,” or the practice of removing a shark fin at sea and discarding the rest of the shark, is illegal in the United States. All domestic shark fisheries are required to land the entire shark at the dock, and are managed according to sustainable fishery management plans.

February 15, 2017 — A bill filed in the state Senate would crack down on the sale and possession of shark fins and shark tails which are considered a delicacy in parts of Asia.

The measure, filed by Sen. Travis Hutson, would make it a first-degree misdemeanor in Florida to trade or offer for sale shark fins or shark tails. Commercial and recreational fishers found in violation would face a suspension or loss of their licenses or permits.

Harvesting Sharks Could Be Key to Saving Them

February 7, 2017 — Sharks and their relatives face an existential crisis unprecedented in their 420 million years on the planet. A global trade in products from these animals fuels the capture of tens of millions of individuals a year. Strong demand combined with poor fishery regulation and high levels of incidental catch have resulted in many populations being overfished, with some now facing extinction.

Many activists argue a total ban on shark fishing is the only solution to slow or halt the decline. But a 2016 study found the majority of shark researchers surveyed believe sustainable shark fisheries are possible and preferable to widespread bans. Many reported they knew of real-world examples of sustainable shark fisheries. But a global roundup of empirical data exploring which species are being fished sustainably was lacking.

New research, appearing in the February 6 issue of Current Biology, is filling that gap, and the findings bolster the idea that around the world, some sharks are being fished sustainably. Nicholas Dulvy, a marine conservation biologist at Simon Fraser University in British Columbia, and shark ecologist Colin Simpfendorfer of James Cook University in Australia recently examined global stock assessments of 65 shark populations of 47 species. They found 39 of the populations, representing 33 different species, are fished sustainably—that is, they are harvested at levels that allow them to remain stable in size and not edge toward extinction. Although these 33 species account for only a small fraction of the world’s sharks, rays and their kin the chimeras (collectively referred to as sharks), which in total number more than 1,000, they are proof of concept that sustainable shark fishing is possible.

Commercial fishing to open for large coastal sharks

January 30, 2017 — The commercial fishing season for non-sandbar large coastal sharks will open in Louisiana waters at 12:01 a.m. on Feb. 1.

The Louisiana Department of Wildlife and Fisheries says federal waters in the Gulf of Mexico will also open at that time. The commercial season will remain open in federal waters until 80 percent of the federal quota has been harvested or is projected to be harvested in the Gulf.

50 NGOs critique MSC over bycatch

January 26, 2017 — A group of 50 non-governmental organizations (NGOs) has sent a letter to the Marine Stewardship Council (MSC) expressing their concerns about its certification of fisheries with high levels of bycatch.

The letter was authored by Kate O’Connell of the Animal Welfare Institute and Friederike Kreme-Obrock of Sharkproject Germany and signed by the heads of 50 nonprofits dedicated to environmental conservation, including dozens of groups dedicated to the protection and preservation of sharks, whales and dolphins.

“Many of our organizations have commented on fishery assessments under the MSC process, and over the years we have noted an apparent, and deeply worrying, lack of concern regarding the potential impacts on these species, as well as certain target species,” the letter said. “It is our view that many of the fisheries that have been assessed via the MSC certification process have not been subject to an adequate review of information available on bycatch of non-target species.”

The letter accuses the MSC of being subjective in interpreting evidence and in estimating the effects of a fishery’s impact on non-targeted species. It cites the absence of in-depth stock assessments for some species of bycatch as a problem under MSC Principle 2, which aims to maintain population levels of all species affected by a fishery at biological based limits.

Air China bans shark fin cargo, reflecting dramatic shift in attitudes

January 9, 2017 — BEIJING — Air China has become the first airline in mainland China to ban shark fin cargo, marking a dramatic shift in attitudes toward trade in endangered wildlife here and throwing a lifeline to shark populations threatened with imminent extinction.

The news, released late Friday, came just a week after China announced plans to ban its domestic ivory trade, a landmark decision of vital importance in ending an epidemic of elephant poaching in Africa.

It marks the country’s gradual transformation from being the biggest source of the problem — as the largest market in illegal wildlife products — to becoming a major part of the solution.

“Scientists estimate that fins from up to 73 million sharks a year are used for shark’s fin soup, with much of the trade in shark fin destined for China,” said Alex Hofford, a wildlife activist from the conservation group WildAid in Hong Kong, which applauded Air China for taking “an ethical stance” to help protect sharks and oceans. “It’s a bold move, and this is likely to have a huge and lasting impact on shark populations and marine ecosystems worldwide.”

Hofford said the decision by China’s national flag carrier “puts FedEx to shame” — the U.S. multinational courier company has resisted repeated calls to take a similar step, despite a petition signed by 300,000 people, and an appeal from a coalition of animal welfare conservation groups who expressed concerns that its service could be used to carry fins of endangered shark species. That would be a violation of the Convention on Trade in Endangered Species (CITES).

Would You Eat This Fish? A Shark Called Dogfish Makes A Tasty Taco

January 9, 2017 — If you’ve never laid eyes on a dogfish — or tasted one — you’re not alone.

Yep, it’s in the shark family. (See those telltale fins?) And fisherman Jamie Eldredge is now making a living catching dogfish off the shores of Cape Cod, Mass.

When populations of cod — the Cape’s namesake fish — became too scarce, Eldredge wanted to keep fishing. That’s when he turned to dogfish — and it’s turned out to be a good option. The day I went out with him, Eldredge caught close to 6,000 lbs. (Check out the video above.)

“It’s one of the most plentiful fish we have on the East Coast right now,” Brian Marder, owner of Marder Trawling Inc., told us. Fishermen in Chatham, Mass., caught about 6 million pounds of dogfish last year.

So, who’s eating all this dogfish? Not Americans. “99 percent of it” is shipped out, Marder says.

The British use dogfish to make fish and chips. The French use it in stews and soups. Italians import it, too. The Europeans are eating it up. But Americans haven’t developed a taste for it. At least, not yet.

The story of the dogfish is typical of the seafood swap. “The majority of the seafood we catch in our U.S. fisheries doesn’t stay here,” explains Jennifer Dianto Kemmerly, who leads the Seafood Watch program at the Monterey Bay Aquarium.

And while we export most of what is caught off U.S. shores, what do Americans eat? Imported fish. About “90 percent of the seafood we consume in the U.S. is actually caught or farm-raised overseas,” Kemmerly says.

To sustainable seafood advocates, this swap doesn’t make much sense. “We’re kind of missing out on the bounty we actually have here,” Kemmerly says.

And, it’s not just dogfish.

The Environmental Defense Fund has launched a campaign called Eat These Fish to tell the story of a whole slew of plentiful fish caught off our shores. The group is trumpeting the conservation success of U.S. fisheries. Some species have been brought back from the brink of extinction through a system of quotas and collaboration between fishermen, conservationists and regulators. They point to fish such as Acadian Redfish and Pacific Ocean Perch.

Selling shark fins now banned in Rhode Island

January 3, 2017 — PROVIDENCE, R.I. — Selling shark fins is now banned in Rhode Island as it is in Massachusetts.

A law took effect Sunday that makes it a crime to own or sell a shark fin unless it’s used for scientific research or in preparing a shark for ordinary consumption.

Rhode Island became the 11th state to ban shark fin sales when Democratic Gov. Gina Raimondo signed legislation into law in June. Hawaii was the first in 2010. Massachusetts banned the sales in 2014.

The Atlantic States Marine Fisheries Commission voted in August to approve a new rule that allows fishermen to bring smooth dogfish, a type of shark, to land with fins removed, as long as their total retained catch is at least 25 percent smooth dogfish.

The rule change better incorporates the Shark Conservation Act of 2010 into management of the dogfish, staff with the fisheries commission said. Dogfish are harvested from Rhode Island to North Carolina, and are among the many shark species that fishermen bring to land in states from Maine to Texas.
