Global Extinction Risk for Sharks and Rays Is High, United States may Provide Haven

December 9, 2024 — Overfishing of sharks and rays has depleted many populations, causing widespread erosion of ecological function and exceptionally high extinction risk. NOAA Fisheries coauthored a study in the journal Science that quantifies the extinction risk for the world’s 1,199 sharks and ray species over 50 years. They found that while sharks and rays are at high risk of extinction and biodiversity loss globally, this risk differs by habitat and region. There are some “bright spots” that could help species survive.

Sharks Are In Rough Shape Globally

We found that sharks and rays globally are in a worse conservation state than all other vertebrate groups, apart from amphibians. We also demonstrated the “fishing down” of shark and ray biodiversity and ecosystem function. This shows that the largest species declined first and most rapidly.

Most sharks and rays have slow population growth rates, which makes them highly vulnerable to overfishing and subsequently takes populations longer to rebuild. Around the world, sharks and rays are targeted for their fins, meat, gill plates, and liver oil. They are also caught incidentally—as bycatch—in other fisheries.

MARYLAND: Maligned cownose ray could be vulnerable to overfishing, study suggests

August 30, 2018 — Chesapeake Bay watermen have long viewed the cownose ray as a pest, preying on a vulnerable oyster population. Their contempt even inspired tournaments of bow-wielding ray hunters — a practice the state has banned, at least temporarily.

But new research backs up concerns that the winged creatures could themselves be susceptible to overfishing, an outcome that some scientists fear could harm the bay’s health.

Scientists at the Smithsonian Environmental Research Center in Edgewater, Md., tracked a group of rays over two years. The rays, they found in research published last week in the journal Marine Ecology Progress Series, spend their winters around Cape Canaveral, Fla., then migrate north in the spring to the same rivers where researchers initially found them — perhaps the rivers and creeks where they were born.

The finding could be valuable as Maryland fishery regulators develop the state’s first plan to manage the cownose ray population, balancing the concerns of the seafood industry with the limited data available on the rays’ place in the Chesapeake ecosystem.

Florida, Alaska Senators Champion Sustainable Shark Fisheries and Trade Act

May 4, 2018 — SEAFOOD NEWS — U.S. Senators Marco Rubio, R-Fla., and Lisa Murkowski, R-Alaska, recently introduced the Sustainable Shark Fisheries and Trade Act (S. 2764), a similar bill introduced in the House — H.R. 5248 — by Rep. Daniel Webster, R-Fla.

A press release from Rubio’s office said the bicameral legislation recognizes the sustainable and economically-valuable fishing practices of U.S. shark fishermen and promotes U.S. standards for shark conservation and humane harvest.

Sharks play an important role in maintaining the health of the ocean ecosystems for which Florida is known, Rubio noted in the statement.

“Sharks are already sustainably and humanely harvested in federal waters per U.S. law, providing sustained economic benefits to coastal communities through fishing, trade, and tourism. This bill will help promote those same standards for sustainable and humane shark harvesting among our global trade partners as well,” Rubio said in the release. “This bill protects international shark populations as well as the fishermen in Florida and throughout the U.S. who continue to fish by the rules.”

Both the senate and house bills are a contrast to other proposed legislation, such as H.R. 1456, directed at the sales of shark fins. Those bills, critics say, will do nothing to eliminate the sales of shark fins globally, punish the domestic seafood industry and could unintentionally create a market for the practice of shark finning by foreign fishermen.

“While the practice of shark finning is already banned in U.S. waters, we do have a small population of fishermen who legally harvest whole sharks for their meat, oil, and other products,” Murkowski said in the statement. “This legislation sets a strong policy example for global nations that wish to prevent shark finning in their waters, while respecting the cultures of communities that rely on subsistence, protecting the rights of American fisherman that operate in the legal shark fisheries, and supporting the efforts of shark conservationists.

“Together, we can find solutions to protect our fisheries, our communities, and our marine ecosystems, worldwide.”

According to Rubio’s office, the Sustainable Shark Fisheries and Trade Act would:

  • Create a shark conservation and trade fairness certification for nations wishing to import shark products to the U.S.;
  • Prohibit the importation of shark products originating from any nation without a certification, and the possession of such products in the U.S. with limited exceptions for law enforcement, subsistence harvest, education, conservation, or scientific research;
  • Update the High Seas Driftnet Fishing Moratorium Protection Act to reflect the U.S. commitment to promote international agreements that encourage the adoption of shark conservation and management measures and measures to prevent shark finning that are consistent with the International Plan of Action for Conservation and Management of Sharks; and
  • Direct the Secretary of Commerce to include rays and skates into the seafood traceability program to ensure that shark products are not smuggled into the U.S. falsely labeled as rays and skates, two closely related groups.

“Fishing is a long-standing profession and treasured American pastime,” Webster stated in the release. “We must pursue conservation, while balancing the needs of the industry and recreation. This bill recognizes the sacrifices American fishermen have made to rebuild and sustain our shark populations. It encourages other nations wishing to export shark products to the United States to adhere to the same high standards for conservation and management.”

Webster’s proposed legislation has 15 cosponsors. It passed the House Natural Resources Subcommittee on Water, Power and Oceans in April. It also has the support of several groups that have opposed H.R. 1456 and related bills. The Mote Marine Laboratory, Florida Fish and Wildlife Conservation Commission (FWC), the Palm Beach Zoo, SeaWorld, Zoo Miami Foundation, the Florida Aquarium, the Southeastern Fisheries Association, Directed Sustainable Fisheries, Louisiana Shrimpers and Garden State Seafood all support Webster’s bill, according to Sunshine State News.

62 Shark Scientists Endorse Bipartisan Shark Sustainability Bill

April 17, 2018 — WASHINGTON — The following was released by the Wildlife Conservation Society:

Ahead of a House Natural Resources Committee hearing on various shark conservation bills, 62 marine scientists with expertise on sharks and rays submitted a letter to the committee calling for passage of the H.R. 5248, the Sustainable Shark Fisheries and Trade Act.

The scientists urge a science-based approach to fisheries conservation and management, as prescribed by H.R. 5248, to significantly reduce the overfishing and unsustainable trade of sharks, rays, and skates around the world and prevent shark finning.

The letter states, “Although it is not the largest importer of shark products, the U.S. is a major shark and skate fishing and exporting country and therefore can lead in both modeling and promoting sustainable shark fisheries management and responsible trade for these species. Continuing to exercise this leadership can help to reverse the declining trend in many shark, skate, and ray populations around the world. We heartily endorse the Sustainable Shark Fisheries and Trade Act of 2018 and strongly urge its prompt passage by Congress.”

The 62 signatories come from research institutions, conservation organizations, and academia. This group also includes 12 past presidents of the American Elasmobranch Society.

Sustainable shark bill nets solutions for overfishing

April 2, 2018 — A new bipartisan bill introduced in U.S. Congress this month encourages a science-based approach to significantly reduce the overfishing and unsustainable trade of sharks, rays and skates around the world and prevent shark finning.

The Sustainable Shark Fisheries and Trade Act of 2018 was introduced in the U.S. House of Representatives by Rep. Daniel Webster, R-FL, and Rep. Ted Lieu, D-CA, along with co-sponsors Rep. Bill Posey, R-FL, Rep. William Lacy Clay, D-MO, and Rep. Walter Jones, R-NC.

The Act would require that shark, ray and skate parts and products imported into the U.S. be permitted only from countries certified by the National Oceanic and Atmospheric Administration (NOAA) as having in place and enforcing management and conservation policies for these species comparable to the U.S., including science-based measures to prevent overfishing and provide for recovery of shark stocks. A comparable prohibition on shark finning — the wasteful and inhumane practice of cutting off a shark’s fins and discarding the carcass at sea — would also be required.

Scientists recognize more than 1,250 species of cartilaginous fishes — sharks and related skates and rays. Of these, as many as one-quarter are estimated to be threatened with extinction, and the conservation status of nearly half is poorly known. These fishes play important ecological roles in their marine and freshwater ecosystems, and many species are culturally and economically important. These fishes are particularly vulnerable to over-exploitation — most grow slowly, mature late and produce few young. Overfishing, through targeted fisheries and incidental catch, is the primary threat to sharks and their relatives, which are harvested for fins, meat, oil, cartilage and other products.

Mote Marine Laboratory Senior Scientist Dr. Robert Hueter served as a scientific reviewer for the Sustainable Shark Fisheries and Trade Act text, providing feedback based on published research and his decades of experience as a shark scientist to inform policymakers who ultimately determined the content of the legislation.

Shark trade bill gains industry, conservationist support

March 22, 2018 — A new bipartisan bill introduced to the U.S. House of Representatives on 13 March would require new certifications for countries importing shark, ray, and skate parts and products to the United States.

H.R. 5248, the Sustainable Shark Fisheries and Trade Act, would require all countries importing products related to sharks, rays, and skates obtain certification by the National Oceanic and Atmospheric Administration. Certification would require evidence that the country has conservation policies, management, and enforcement in place that is comparable to similar programs in the U.S.

The bill was introduced to the house by Rep. Daniel Webster (R-FL) and Rep. Ted Lieu (D-CA) along with co-sponsors Rep. Gus Bilirakis (R-FL), Rep. William Lacy Clay (D-MO), Rep. Walter Jones (R-NC), Rep. Bill Posey (R-FL), and Rep. Darren Soto (D-FL). The goal, according to Webster and Lieu, is to promote the science-based regulations the U.S. has had in place for years while leveling the playing field between U.S. fisherman and their overseas competition.

“Fishing is a long-standing profession and treasured American pastime, and particularly important in Florida,” Webster said.  “This bill recognizes the sacrifices American fishermen have made to rebuild and sustain our shark populations. It encourages other nations wishing to export shark products to the United States to the same high standards for shark, skate, and ray conservation and management we apply to fishermen here.”

The bill has already garnered supporters from within the industry. Bob Jones, the executive director of the Southeastern Fisheries Association, said the bill represents “A better way forward.”

“This legislation goes a long way toward combating the threats facing global shark stocks by promoting the successful model of American shark management,” he said.

Other industry supporters include the Garden State Seafood Association, Directed Sustainable Fisheries, and the North Carolina Fisheries Association.

Conservation groups also support the bill. A coalition of more than 40 organizations including the Wildlife Conservation Society (WCS), Association of Zoos and Aquariums, and the International Fund for Animal Welfare, have begun a campaign to support the passage of the Sustainable Shark Fisheries and Trade Act.

ISSF Report Analyzes Purse Seine Tuna Fishing Impacts on Sharks, Rays, and Other Species

November 28, 2017 — The following was released by the International Seafood Sustainability Foundation:

Using data from Regional Fisheries Management Organizations (RFMOs), scientific observer programs, and its own at-sea research and skippers workshops, the International Seafood Sustainability Foundation (ISSF) has published an updated report that documents purse-seine tuna fishing’s impact on “non-target” species. The bycatch species covered in the report are sharks, whale sharks, rays, finfish, sea turtles, and billfish. While they are not bycatch species, the report also touches upon catches of undesirably small bigeye and yellowfin tunas.

Organized by species and including graphics and a full bibliography, “ISSF 2017-06: A Summary of Bycatch Issues and ISSF Mitigation Activities to Date in Purse Seine Fisheries, with Emphasis on FADs”:

  • Identifies issues of concern for each species
  • Summarizes the effectiveness of different bycatch-mitigation practices — at different stages of fishing operations — for either avoiding non-target species or reducing their mortality when caught
  • Describes ongoing ISSF bycatch research activities
  • Lists existing RFMO measures for minimizing bycatch

“A Summary of Bycatch Issues” is intended to be a useful reference for fishers and tuna companies, scientists, regional fisheries management organizations (RFMOs), government agencies, nongovernment organizations (NGOs) including conservation groups, and others interested in helping fisheries to be more sustainable.

Report Data and Insights Can Guide Conservation Efforts
The November 2017 report, authored by ISSF staff and collaborating scientists Victor Restrepo, Laurent Dagorn, David Itano, Ana Justel-Rubio, Fabien Forget, and Gala Moreno, is an update of a 2014 publication.

Not all non-target species are equally vulnerable to becoming bycatch in purse-seine fisheries, and bycatch rates for a single species can vary across oceans. For some species, other fishing methods have higher bycatch than purse-seine fishing. Here are some key findings in the report:

  • SHARKS: 90% of sharks that become entangled in FAD nets in purse-seine fisheries are silky sharks (Carcharhinus falciformis); the oceanic whitetip shark ( longimanus) is another bycatch species. By avoiding setting on small schools of tuna (e.g. < 10 tons) around FADs, fishers could significantly reduce their catches of silky sharks by 20% to 40%, depending on the ocean.
  • WHALE SHARKS: Whale shark (Rhyncodon typus) interaction rates with purse seiners are very low: The Western and Central Pacific Fisheries Commission (WCPFC), for example, recorded a set encounter rate of 0.94%. But any whale shark fishing mortality is a concern due to their life history and ecological significance. Time/area fishing closures do not appear effective for avoiding catching whale sharks, but best practice guidelines for their release exist.
  • RAYS: Rays are not common bycatch in purse seine fisheries, at less than 0.1% by weight, and are mostly caught in free-school sets. Release from the deck is a viable alternative to release from the net. Fishers should avoid using hooks, wires or tightening slings and lifting or dragging by the gill slits or cephalic lobes.
  • SEA TURTLES: Sea turtles are caught in very small numbers by purse seiners, with most (> 90%) released alive relatively easily. Using non-entangling FADs can prevent turtle entanglement.
  • UNDESIRABLY SMALL BIGEYE AND YELLOWFIN TUNAS: Bigeye and yellowfin are not considered non-target species. Nonetheless, FAD fishing for skipjack stocks can result in higher catches of small bigeye and yellowfin, which can contribute to their overfishing. The species’ slower growth rates, higher longevity and higher age at maturity increase vulnerability to fishing. Mitigation efforts being evaluated include: adjusting the relative prices of small bigeye and skipjack tuna; setting species-specific quota; temporarily closing to fishing some areas of high concentrations; or managing the number of fishing sets on floating objects.

ISSF on Bycatch Mitigation
Since its inception in 2009, ISSF has dedicated resources and efforts to understanding bycatch issues in tuna fisheries (see “Related ISSF Activities” sections in the report). In addition to publishing scientific reports, ISSF hosts bycatch-mitigation workshops and publishes guidebooks and videos for skippers and other stakeholders. The Foundation also advocates science-based, mitigation measures to RFMOs through meetings and side events, position statements, and joint letters.

Commercial vessels catch about 4.7 million tons of tuna annually. Purse-seine vessels dominate large-scale tuna fishing, harvesting about 64% of the tropical tuna catch (skipjack, yellowfin, and bigeye tuna). Many purse seiners use Fish Aggregating Devices (FADs) or other floating objects to attract tuna to their nets, although they also may pursue sets on free-swimming tuna schools. More than half of the total tropical tuna landings globally are made by sets on FADs or other floating objects.

Bycatch occurs across most major tuna fishing methods — including longline, gillnet, and troll — and all fishing methods can affect the marine environment in multiple ways beyond bycatch.
