U.S. blocks Mexican fishermen from ports, cites years of illegal fishing in U.S. waters

February 9, 2022 — Along the U.S.-Mexico maritime border, the incursions occur almost daily. The boats are outfitted with small outboard motors, powerful enough to flee pursuing Border Patrol and Coast Guard vessels.

The Mexican skiffs are loaded not with drugs or migrants, but with red snapper, sea turtles and sharks.

U.S. officials say the threat posed by Mexican fishermen casting their nets illegally in U.S. waters has grown so acute that for the first time in years, they’ve banned Mexican fishing vessels from entering U.S. ports.

“These vessels … will be denied port access and services,” said Lauren Gaches, a spokesperson for the National Oceanic and Atmospheric Administration. She said the sanction was being applied in response to Mexico’s “continued failure to combat unauthorized fishing activities by small hulled vessels in U.S. waters.” It took effect Monday.

New ASU study identifies research priorities for threatened sharks

February 1, 2022 — Sharks are some of the most threatened animals on Earth, and while many scientists want to dedicate their research to helping to save sharks, many report that they don’t know how to do this effectively.

A new paper in the journal Conservation Science and Practice, led by Arizona State University Faculty Research Associate David Shiffman, has identified 35 research priorities that scientists can use to shape their research on threatened shark species in the United States.

“Lists of research priorities help scientists, especially early career scientists, to choose a research project that can have a real impact,” Shiffman said. “Instead of having to figure out the complexities of policymaking and management on your own to learn what information managers need, lists of research priorities give scientists a one-stop shop to easily find everything. These scientists know that a question they’re hoping to answer with their work is a research priority because it’s already been identified as one.”

To generate this list of research priorities, the team from ASU’s New College of Interdisciplinary Arts and Sciences surveyed 86 experts from the fields of scientific research, environmental advocacy, natural resource and fisheries management, endangered species conservation and industry from throughout the United States. These experts were asked to reflect on what information we don’t currently know about threatened sharks that we need to know, and to propose research priorities as well as policy priorities.

MASSACHUSETTS: Fear on Cape Cod as Sharks Hunt Again

October 25, 2021 — Over the past decade the waters around Cape Cod have become host to one of the densest seasonal concentrations of adult white sharks in the world. Acoustic tagging data suggest the animals trickle into the region during lengthening days in May, increase in abundance throughout summer, peak in October and mostly depart by the dimming light and plunging temperatures of Thanksgiving. To conservationists, the annual returns are a success story, a welcome sign of ecosystem recovery at a time when many wildlife species are depleted. But the phenomenon carries unusual public-safety implications. Unlike many places where adult white sharks congregate, which tend to be remote islands with large colonies of sea lions or seals, the sharks’ summer residency in New England overlaps with tourist season at one of the Northeast’s most coveted recreational areas. Moreover, the animals are hunting in remarkably shallow water, at times within feet of the beach. This puts large numbers of people in close contact with a fast and efficient megapredator, historically the oceans’ most feared fish.

Among critics of the white-shark status quo, disillusionment runs deep. Other members of the Cape Cod Ocean Community, including Drew Taylor, reject the reliance on nonlethal approaches. Taylor proposes challenging policy and amending federal law to allow communities to set preferred population levels for white sharks and gray seals and permit hunting or fishing to reduce their numbers. Conservation laws, he said, were understandable in intent but lack tools to deal adequately with rebounds of this scale. “How can you write a law that protects something in perpetuity?” he said. His views, like those heard in human-wildlife conflicts elsewhere, can be summarized like this: It’s perfectly reasonable to find lions or cobras or white sharks captivating but not want hundreds of them feeding in your neighborhood park. He blames federal policies for fostering biological and social dynamics that force people to yield without question or recourse to dangerous or nuisance animals. Marine mammals, he noted, enjoy protection that terrestrial mammals do not; a sole black bear that roamed Cape Cod in 2012, for example, was promptly tranquilized and removed.

Greg Connors, captain of the 40-foot gillnet vessel Constance Sea, which fishes from Chatham, said environmentalists and bureaucrats have not fully considered the gray seal recovery’s effect on people who live on the water. Seal advocates and scientists, he said, have not shown convincing evidence that the historic seal population in New England was as large as it is now and operate on assumptions that all increases are good. At some point, he said, other voices and interests should be balanced against those in control. “They never set a bar on how high they want it to get,” he said of the seal population. “It’s always just more. That’s a terrible plan.” Seals, he said, have done more than attract white sharks; they have driven fish farther to sea and steal catches from nets. Nick Muto, the lobster captain, said marine-mammal protections, as designed, defy common sense. Why, he asked, do protections apply equally to North Atlantic right whales, of which perhaps 400 animals remain, and gray seals, which in the western Atlantic number roughly half a million? He was surprised that Medici’s death didn’t change the official stance. “I thought once somebody died here,” he said, “it would be lights out for the seals.” Connors and Muto acknowledge there is little chance for an amendment, an assessment shared by their industry group. “We’re under no illusion that there is going to be a cull,” said John Pappalardo, who heads the Cape Cod Commercial Fishermen’s Alliance. “Blood on the beach? People would not tolerate that.” But frustrations capture the degree to which one side feels overtalked and alienated by the other, including many people whose lives center on the water.

Some sharks are more likely to die after ‘catch and release,’ study finds. Here’s why

September 24, 2021 — Longlining, a commercial fishing technique that drags a main line with baited hooks through the water, is convenient when catching massive amounts of swordfish and tuna, but it also traps what experts call “bycatch” — unintended victims that may face dark fates after release back into the ocean.

Sharks are often attracted to and caught on these baited longlines; it’s one of the many culprits behind declining shark populations. Certain rules called “no-take regulations” require fishermen to release some species when accidentally hooked, but a new study of over 300 sharks found that some are much more likely to die after “catch and release” than others. The study was published Sept. 15 in the journal PLOS One.

“The assumption behind no-take regulations is that the shark will swim away and live out its normal life after it’s released, but we know that for some sharks, that’s not true,” study lead author Dr. Nick Whitney, senior scientist at the New England Aquarium’s Anderson Cabot Center for Ocean Life in Massachusetts, said in a news release.

After five years of longline fishing that targeted five of the seven most commonly caught species in the Gulf of Mexico and Florida Keys, the researchers learned as many as 42% to 71% of blacktip and spinner sharks will die after being caught and released alive. Others, such as sandbar and tiger sharks, were more resilient; only 3% or fewer died after release. Bull sharks were also one of the more hardy species. The animals were caught near Madeira Beach, Key West and Naples, Florida.

The team learned 90% of the post-release deaths occurred within five hours of returning to the water, and 59% occurred within just two hours. Blood samples and tracking data revealed the stress of the capture process, or injuries acquired during it, leads to the unnecessary and disproportionate demise of some sharks.

White shark tracking organization releases findings after tagging 3 sharks during New England research expedition

August 30, 2021 — OCEARCH has released the findings of its 41st Ocean Research Expedition in New England where they were successfully able to sample, tag, and release three white sharks. The organization says the data collected from these sharks will support 23 science projects, helping “form a complete picture of the ecology, behavior and health of the white shark in the Northwest Atlantic Ocean.”

Expedition New England departed from New Bedford on Aug. 1 and spent the first week fishing in federal waters outside of Cape Cod and Nantucket before heading to the Isle of Shoals off of New Hampshire, and ending in Gloucester on Aug. 20.

OCEARCH’s Northwest Atlantic White Shark Study is the most comprehensive research study that has ever been done on a white shark population and the data collected from the three sharks tagged and sampled on Expedition New England will support 23 different research projects including full health assessments, bacterial and microbiome studies and microplastic toxin exposure. In addition, the three tags added to each of these sharks will allow scientists to track their long-term movements as they grow into young adults.

Six Ways Fishermen Keep Shark Fishing Sustainable

August 26, 2021 — The following was released by NOAA Fisheries:

U.S. shark fisheries are among the most sustainably managed commercial and recreational fisheries in the world. Here are six things fishermen do to help help us maintain a sustainable shark fishery:

1. Have the Proper Permits

Fishermen need a federal fishing permit to fish for sharks. These permits, issued by NOAA Fisheries, help us communicate and enforce regulations and monitor how many sharks are caught.

2. Follow Bag and Size Limits

Commercial fishermen follow annual catch limits, gear restrictions, closed areas, and retention limits when fishing for sharks. The recreational shark fishery also has bag and size limits. These limits maintain the sustainability of the shark fishery by controlling the harvest. Minimum size limits protect many juvenile sharks from harvest and ensure they have the opportunity to mature and reproduce.

3. Use Circle Hooks

Fishermen use circle hooks when using their rod and reel or longline fishing gear to catch sharks. Circle hooks increase the chance of hooking a shark in the jaw instead of the gut. This reduces injury to the shark’s internal organs and increases their chance of survival when released. A shark that is hooked in the jaw is easier and safer to dehook. The only exception to using circle hooks is when recreational anglers are fishing with artificial lures or flies.

4. Fins Attached

Fishermen land sharks with their fins still attached. This prevents the cruel and wasteful practice of finning, which has been banned in the United States since 2000. Only sharks landed under the strict and sustainable commercial restrictions mentioned above may have their fins removed and sold after landing.

5. Identify Shark Species 

Commercial fishermen that use longline or gillnet gear are required to attend Handling and Release workshops where they learn which species they can keep and how to release those that are prohibited (including learning about the best ways to release sea turtles and marine mammals). Recreational fishermen are also trained in Catch and Release Best Practices so they know how to handle and safely release sharks. There are more than 20 prohibited shark species in the Atlantic and Gulf of Mexico. If a fisherman accidentally hooks a prohibited species, they release them in a manner that enhances survival. Both commercial and recreational fishermen use shark identification guides to help identify which sharks they are catching

6. Report Catch

Fishermen report their catch through various programs, including:

Commercial landings are also reported through dealer reports.

Collecting information on catch and landings helps assure the sustainability of the shark fishery. The data from these programs are essential to support stock assessments that determine how much harvest a fishery can support and whether current harvest levels are within sustainable limits.

John “Jack” Casey: Internationally Recognized Shark Researcher, Mentor, and Narragansett Lab Co-Founder

August 24, 2021 — The following was released by NOAA Fisheries:

John “Jack” Casey was born and raised in Turners Falls, Massachusetts. Two days out of high school, he enlisted in the U.S. Navy, where he served for 4 years on the destroyer escort USS Raymond. Following his military service, he returned to Turners Falls and worked at a paper mill for about 18 months. Seeking more on his horizon, Casey returned to school. He spent 2 years at the University of New Hampshire and 2 years at the University of Massachusetts, where he earned his bachelor’s degree in wildlife management in 1960.

That same year, Casey started working at the U.S. Fish and  Wildlife Service’s Bureau of Sport Fisheries and Wildlife laboratory at Sandy Hook, New Jersey. He began to study sharks of the Northwest Atlantic Ocean in 1961, when sharks were unstudied and misinformation abounded.

Realizing just how much information could be obtained by working with sport and commercial fishermen, Casey initiated the Cooperative Shark Tagging Program in 1962 with less than 100 volunteer fishermen who were eager to help science. Since then, thousands of fishermen have stepped up to join forces with NOAA Fisheries to tag sharks all over the Atlantic.

Fishermen participating in the program have tagged more than 300,000 sharks and recaptured more than 18,000 of many different species. Data gathered through the program are a font of information on the distribution, movements, and migration of more than 30 shark species. The program has resulted in numerous publications, and served as the basis for undergraduate honors projects, master’s degree theses, and Ph.D. dissertations. Most well-known, however, are the two “shark atlas” publications showing the first detailed distributions and movements of tagged Atlantic sharks.

In 1970, NOAA was created by executive order. The U.S. Fish and Wildlife Service’s Bureau of Commercial Fisheries and the saltwater labs of its Bureau of Sport Fisheries and Wildlife were combined and moved to NOAA to form the National Marine Fisheries Service, now informally known as NOAA Fisheries. Casey was instrumental in setting up the new NOAA marine fisheries laboratory in Narragansett, Rhode Island. The Apex Predators Program he founded moved from the Sandy Hook Laboratory (which was by then also part of NOAA’s new fisheries service) to the Narragansett Laboratory. It remains there to this day.

Casey founded the Cooperative Shark Tagging Program and changed the course of knowledge on Atlantic shark movements and distribution. That alone is enough to make him a NOAA Fisheries science superhero. But Casey simultaneously started a life history program on sharks encompassing age and growth, reproduction, and food habits. His team produced groundbreaking science on all aspects of shark biology. Collaborations between Casey’s team, its successors, and experts at other institutions have led to widespread use of program data. They have exponentially increased our knowledge of sharks in the Atlantic. These lines of research continue to provide direct support for maintaining sustainability of these species.

Jack Casey is recognized nationally and internationally among his peers. He has been an invited speaker at scientific meetings around the world. He has appeared on several sportfishing shows, and authored or co-authored numerous scientific and popular articles. He has been honored with numerous awards, including the Department of Commerce bronze medal and the bronze medal awarded by the Morski Institute (Poland’s national marine fisheries service). He was also named a distinguished fellow by the American Elasmobranch Society. Through his outreach and public education work, he helped turn the public perception of sharks from “the only good shark is a dead shark” to the conservation-oriented value placed on sharks today.

As a pioneer in shark research, Jack Casey‘s influence is global and has proliferated through generations of students he has mentored and who have chosen careers in shark research. His contribution to shark science has been aided by his fighting spirit and determination. His excitement for sharks and his charismatic personality helped him forge a diverse group of volunteers into a team of collaborators dedicated to furthering shark research.

SEAN HORGAN: On Henri, a Bell, and sharks

August 23, 2021 — Sharks were back in the news last week, which should make our pal Bob Masjoan at the Crow’s Nest happy. He is all sharks, all of the time.

One time, during Shark Week, a misguided Irish soul, we’ll call him Cormac, asked Bob to turn the bar’s largest television to a European Cup soccer match instead of the shark fest. His request was rebuffed with extreme pelagic prejudice.

Anyway, no shortage of sharks last week. One viral video showed a herd of sharks — whites, blues et al — feasting on the carcass of a dead humpback whale out on Stellwagen Bank while an intrepid shark researcher on a tagging project lingered in his sea kayak mere feet away.

Us? We would have requisitioned a Los Angeles-class submarine.

Then came a fisherman’s photo — we spied it on the website of radio station WOKQ 97.5 — of a huge hammerhead shark swimming somewhere off the coast of Maine, looking for all the world like the most evil creature on the planet.

The accompanying story said hammerhead attacks on humans are rare — only 16 documented throughout the world, none fatal.

The piece also said the hammerheads are more afraid of us than we are of them. We here at FishOn are here to tell you that is not even remotely true.

UK Government Introduces New Ban On Shark Fin Trade

August 20, 2021 — In order to promote shark conservation, a ban has been initiated on the import and export of detached shark fins, the UK Government announced. This ban will include shark fin products like tinned shark fin soup.

Shark species are facing population decline, and shark finning is a huge force behind this. Out of over 500 species of shark, 143 are listed as ‘under threat’ under the International Union for Conservation of Nature. A key indicator and sign of ocean health is the presence and amount of sharks in marine areas. Sharks also play a major role in marine ecosystems because they help maintain healthy and normal levels of fish lower to them in the food chain.

Six Steps to Sustainable Sharks

August 11, 2021 — The following was released by NOAA Fisheries:

NOAA Fisheries ensures that United States fisheries are some of the most sustainable in the world, including sharks. Of the 479 fish stocks or stock complexes we manage, 43 are shark species in the Atlantic Ocean. Here we’ve broken down our management approach into six steps:

Step One: Research

Scientists spend months at sea and in the lab every year, collecting vital data on different marine species, including sharks. Shark research is conducted on NOAA’s fleet of research ships, or through its cooperative research programs. That’s where NOAA researchers work in conjunction with university scientists, the fishing industry, or other stakeholders to perform research activities. To see some of our shark research in the Atlantic, click below:

Step Two: Assessment

Using the data collected about shark stocks, our scientists in coordination with other scientists and partners complete a stock assessment to measure the impact of fishing on these stocks. Assessments use the best information available, which may include data from fisheries landings, scientific surveys, and biological studies. They predict catch levels that maximize the number of fish that can be caught every year while preventing overfishing (removing too many fish). These limits protect the marine ecosystem and, where necessary, rebuild overfished (depleted) stocks. Results of stock assessments are used for setting sustainable levels of fishing under the authority of the Magnuson-Stevens Act.
