World-renowned Mote shark scientist retires

March 5, 2021 — The following was released by Mote Marine Laboratory & Aquarium:

After more than 40 years of shark science with profound conservation impacts, Dr. Robert (Bob) Hueter retired from his role as Director of Mote Marine Laboratory’s Center for Shark Research in December 2020, becoming a Mote Senior Scientist Emeritus.

Hueter’s shark research has spanned six of Earth’s seven continents, and lately he is best known for trailblazing work in Cuba—including satellite-tagging the first sharks in Cuban waters—and the U.S., where he has combined his roles as Mote Senior Scientist and Chief Scientist for the nonprofit organization OCEARCH to lead groundbreaking studies of great white sharks.

Hueter’s research has produced more than 200 published scientific articles and reports, and his career exemplifies Mote’s mission—conducting world-class research and translating it to benefit the oceans and society. He has testified before the U.S. Congress three times on shark research and conservation and has spearheaded landmark developments—including promotion of the first shark fisheries management regulations in Florida in 1991, and the first international shark fisheries management and conservation conference, held at Mote in 1993, where the first U.S. federal shark fisheries management plan was announced.

Over the years, the exceptional research led by Hueter and his team has included: sweeping surveys of sharks along Florida’s Gulf Coast to document long-term changes in their populations; a satellite-tagging study of record scope with whale sharks, Earth’s largest fish species, that documented their migrations spanning over 5,000 miles; through collaborative expeditions with OCEARCH and partners, successfully tracking 70 great white sharks with satellite transmitters and proposing a model of their life history and migrations in the Northwest Atlantic; leading field research identifying nursery areas for 16 shark species in the Gulf of Mexico; and groundbreaking studies on intensive shark fishing in Mexico’s Gulf of California that documented 160,000 sharks and rays in the fishery over years. He also played leading roles in: providing the first scientific documentation of a shark nursery area in Cuban waters, for the lemon shark; gaining new insights on sharks caught in northwest Cuba’s open-water longline fishery; documenting shark bycatch to support development of fisheries electronic monitoring systems in the Gulf of Mexico; contributing data and expertise to massive, global studies of shark-fishery interactions, reef shark conservation and declines; and more.

MSC urged to raise the bar on shark-finning

February 17, 2021 — A new report by a cadre of scientists and members of environmental NGOs is calling on the Marine Stewardship Council (MSC) to take further action to combat the practice of shark-finning.

The report, which analyzed the MSC’s policies relating to shark-finning, asserts that the organization should adopt a “fins naturally attached” (FNA) policy in order to curtail – and hopefully eliminate – shark-finning. The council is failing its zero-tolerance policy on shark-finning, a press release from the organizations behind the report said.

New technology expected to play a key role in shark research

December 29, 2020 — There was precious little good news in 2020, but at least, for the second year in a row, we didn’t see any shark attacks on the Cape.

Unfortunately, the same could not be said for Maine, where a great white shark killed a New York City woman while she was swimming in Harpswell in July. It was the first such attack in the state’s recorded history.

Cape Cod’s first shark attack was in 2012 — the first fatality in Massachusetts in 82 years occurred in Wellfleet in 2018.

The Maine death, along with an increase in the frequency of sightings and detection of tagged white sharks along the New England coastline, helped spur the foundation of the regional New England White Shark Research Consortium this month with the goal of sharing information and research.

With the largest population of great white sharks on the East Coast, Cape Cod is home to cutting-edge research intended to protect the species as well as the millions of beachgoers who come to the peninsula each summer for fun in the surf. While much of that research effort still lies in finding and observing these large marine predators the old-fashioned way with spotter planes and boats, new technologies give scientists hope they will unlock the mysteries of behavior and life history that will allow sharks and humans to coexist.

KRISTEN MINOGUE: Shark tags reveal an endangered species returning to natural refuge

December 28, 2020 — In the coastal waters of the mid-Atlantic, an endangered shark is making a comeback. Led by former Smithsonian postdoc Chuck Bangley, scientists at the Smithsonian Environmental Research Center (SERC) tagged and tracked nearly two dozen dusky sharks over the course of a year as part of the Smithsonian’s Movement of Life Initiative. They discovered that a protected zone put in place 15 years ago is paying off — but with climate change, it may need some tweaking.

Dusky sharks are what Bangley calls “the archetypal big, gray shark.” Born 3 feet long, as babies, they’re already big enough to prey on some other shark species. But they’re slow-growing. It can take 16 to 29 years for them to mature. If their populations take a hit, recovery can take decades.

An endangered species, duskies aren’t very common in Delaware waters. When they do surface, they’re easily mistaken for sandbar sharks. But in this new study, the Smithsonian tracked dusky sharks swimming past the southern tip of Delaware on their migrations up and down the Atlantic. For conservationists, it’s a sign that protections put in place are slowly starting to pay off.

The sharks’ numbers plummeted in the 1980s and 1990s, when well-intentioned managers offered sharks as an “alternative fishery,” while other stocks, like cod, were collapsing. The overfishing that followed wiped out anywhere from 65% to 90% of the Chesapeake’s duskies, said Bangley, now a postdoc at Dalhousie University in Nova Scotia. Managers banned all intentional dusky shark fishing in 2000. Five years later, they created the Mid-Atlantic Shark Closed Area along the North Carolina coast. The zone prohibits bottom longline fishing, which can ensnare dusky sharks, for seven months of the year.

Hawaii Fishing Fleet Is Changing Gear To Help Protect Endangered Sharks

December 7, 2020 — The Hawaii Longline Association announced this week it’s making key changes to its fleet’s fishing equipment to help the imperiled oceanic whitetip shark stave off extinction.

Specifically, by July, crews aboard the fleet’s 140 or so vessels plan to replace the steel wire fishing leaders at the ends of their fishing lines with ones made from less-lethal nylon, or monofilament, according to HLA Executive Director Eric Kingma.

The move should at least somewhat help the endangered and overfished sharks, local fishing officials and industry watchdogs say, because they can bite through the nylon more easily and free themselves when they’re inadvertently caught.

It’s a much-welcomed change to aid a species that was abundant in the central and western Pacific Ocean before commercial fishing and demand for shark fins decimated their numbers, ocean conservationists say.

International consortium created to study the white shark

December 7, 2020 — Shark research groups and government agencies in the United States and Canada announced Tuesday the establishment of an organization that will unite over a dozen agencies to collaboratively study the white shark.

The New England White Shark Research Consortium joins organizations and universities in Massachusetts—such as the New England Aquarium and University of Massachusetts Dartmouth—with researchers in Maine, Rhode Island, New Hampshire, Arizona and Canada.

The group has two primary goals: advance researchers’ current understanding of the white shark, and enhance public education and safety within the region.

Gregory Skomal, the senior fisheries scientist for the Massachusetts Division of Marine Fisheries (which is a consortium member), said the fatal shark attack of a 63-year-old woman off the coast of Maine this summer prompted the creation of the consortium.

“It really pointed to a need for us to coordinate research here in New England,” Skomal said, noting many people were surprised by the location of the attack even though researchers knew white sharks are historically found in Maine waters.

International consortium to study great white shark behavior in Atlantic Ocean

December 2, 2020 — The great white shark now has an international consortium of governments, universities, and private groups — including authorities from Massachusetts — studying the fearsome predator’s behavior in the northwest Atlantic Ocean.

The sharks have returned to coastal New England and southern Canada in increasing numbers during recent years, sometimes leading to fatal interactions with humans it encounters who are swimming or surfing in the ocean.

Among other completed and forthcoming research the consortium plans to use hundreds of receivers to acoustically track great whites from Rhode Island to Canada in hopes of eventually creating “shark forecast maps” that will alert swimmers when shark activity along beaches is at its most intense, said Megan Winton,chief research scientist for the Atlantic White Shark Conservancy which provides the popular SHARKTIVITY app.

Hawaii longliners will convert to mono leaders

December 2, 2020 — Longline fishermen based in Hawaii will voluntarily switch to using monofilament leaders on their gear to promote shark conservation, the Hawaii Longline Association announced this week.

Based at Honolulu Harbor, the fleet of about 140 active vessels produces 90 percent of U.S. bigeye tuna and 50 percent of its swordfish and was sixth in landed value among U.S. ports with $100 million in 2018. The longline fishery is closely monitored and uses a suite of mitigation tools to reduce interactions with protected species.

That includes a 45-gram minimum weight on baited lines so they sink quickly and out of depths where seabirds forage and use of circle hooks to reduce interactions with sea turtles and false killer whales. But sharks are still more likely to be caught by circle hooks, according to the association.

“Hawaii longline vessels don’t retain sharks and most are released alive, but since most sharks are unable to bite through a wire leader, some sharks die on the line,” the group explained in a statement. “Unfortunately, this includes oceanic whitetip sharks, which are now listed as ‘threatened’ under the Endangered Species Act.”

New regional shark research consortium established

December 2, 2020 — The fatal great white shark attack on swimmer Julie Dimperio Holowach in July in Harpswell, Maine, caught many in the shark research community by surprise.

While it was known that some great whites do travel north into Canadian waters in the summer, there was little in the way of sightings, and just a smattering of attacks on seals.

Holowach was the only confirmed fatality from a shark attack in Maine history, according to Patrick Keliher, state Division of Marine Resources director. Cape Cod, with hundreds of great whites patrolling beaches and daily sightings in the summer months, has had two major attacks on swimmers and a fatal attack on a bodyboarder.

“The incident really did rattle the state of Maine, and justifiably,” said Gregory Skomal, Massachusetts Division of Marine Fisheries shark expert. “A lot of us doing work on white sharks reached out to assist.”

Hawaii Longline Vessels to Improve Shark Conservation with Gear Change

November 30, 2020 — The following was released by the Hawaii Longline Association:

Hawaii-based longline vessels will voluntarily switch to monofilament leaders to promote shark conservation, the Hawaii Longline Association (HLA) has announced.

The Hawaii longline fishery is among the most comprehensively managed in the world. With around 140 active vessels based out of Honolulu Harbor, the fleet is highly monitored and subject to a suite of leading protected species mitigation measures. These measures include requiring 45-gram minimum weights so that hooks will sink quickly out of seabird foraging depths, as well as the use of a type of “circle” hook that reduces the severity of interactions with sea turtles and false killer whales.

Although beneficial for sea turtles and false killer whales, sharks are more likely to be caught by the circle hooks. Hawaii longline vessels don’t retain sharks and most are released alive, but since most sharks are unable to bite through a wire leader, some sharks die on the line. Unfortunately, this includes oceanic whitetip sharks, which are now listed as “Threatened” under the Endangered Species Act.

Switching to monofilament leader material will allow sharks to bite through the line just above the hook, thus reducing the severity of the interaction that otherwise would occur using wire leaders. Monofilament leaders will also facilitate releasing sharks and other animals, as the material is much easier to cut than wire. Crew safety remains paramount, and the transition to monofilament leaders will be phased to ensure safety. However, the Hawaii Longline Association is setting July 1, 2021 as the target for the fleetwide conversion.

“This is an industry-led initiative to promote shark conservation and another example of the Hawaii longline fleet as a global leader in responsible fishing practices,” says HLA Executive Director Eric Kingma, PhD.
