Dr. David Shiffman talks shark conservation at DC’s Profs and Pints

August 16, 2019 — At Washington DC’s regular Profs and Pints discussion series, shark expert Dr. David Shiffman shared shark facts, while discussing shark conservation and the threats currently faced by sharks. The talk brought a scientific perspective to some of the most debated topics in shark conservation, including managing sustainable shark fisheries and the efficacy of shark fin bans.

A major focus of the talk was on proposals in the U.S. that would ban the sale of legally caught shark fins, a subject of a recent paper co-authored by. Dr. Shiffman. Noting that the practice of shark finning—the removal of fins from sharks at sea—has long been illegal in the United States, and that the U.S. has some of the best managed shark fisheries in the world, Dr. Shiffman is critical of the idea that a ban would be useful for shark conservation.

“Banning a sustainable fishery here does not do anything to stop an unsustainable similar fishery somewhere else,” he said. “If we are not involved in the market we have no way to influence the market directly.”

Instead, the best way for the U.S. to combat unsustainable practices is to serve as a model for good shark management worldwide. A bill introduced in Congress, the Sustainable Shark Fisheries and Trade Act, would take this approach, requiring all shark products sold in the U.S. to come from sustainable fisheries, and providing support to improve global shark fishing practices.

Dr. Shiffman also noted during the talk that these unsustainable fishing practices globally are a far greater threat to sharks than shark finning. However, he added that these fisheries can be approved by adopting more sustainable management, and that several shark fisheries, many of which are in the U.S., are already well-managed.

“Sustainable shark fisheries can and do exist,” he said.

Profs and Pints is a regular speaker series that “brings college faculty members into bars, cafés, company offices, and other off-campus venues to share their knowledge.” It regularly hosts events in Washington, Chicago, Dallas, Nashville, and Philadelphia.

 

Savannah leads in shark fin exports

August 12, 2019 — For the last five years the port of Savannah has been the U.S. leader in the export of fresh shark fins, a legal but controversial trade item essential for shark fin soup, an Asian delicacy.

Last year, more than 18,000 pounds of shark fins, valued at about $808,000 was exported from Savannah. All of it was shipped to Hong Kong. (While Savannah led in the value of shark fins exported, a larger amount of fins, at nearly 37,000 pounds, was shipped out of Galveston, Texas.)

“Savannah is the No. 1 exporter of shark fins in the United States,” said Cathy Liss, president of the nonprofit Animal Welfare Institute. “Georgia plays an unfortunate role in the lucrative, billion-dollar shark fin trade. As long as we continue to provide a marketplace for shark fin products, the United States, including Georgia, will undoubtedly contribute to the destruction of shark populations.”

New York set to work with fishermen on offshore wind research

August 9th, 2019 — New York state energy officials announced Thursday more than $2 million has been allocated for new studies on how offshore wind energy development will affect fisheries and wildlife.

The projects include joint efforts with the Responsible Offshore Development Alliance, a coalition of East Coast fishing and seafood industry groups that have been advocating for the state and federal governments to move more cautiously on proposals for massive turbine arrays in Northeast and Mid-Atlantic waters.

The next studies continue offshore environmental surveys begun in 2017 by the New York State Energy Research and Development Authority, including digital aerial surveys of birds, marine mammals, sharks and fish shoals that concluded in spring 2019 after collecting more than 3.5 million images across the New York Bight.

NYSERDA originally set out with 20 studies of environmental, social, economic and regulatory issues with building offshore wind power in one of the nation’s busiest seaways. The new studies will build on that with more environmental, maritime and social issues to analyze.

The Fight Over Shark Fins in Florida

August 6, 2019 — The fight for sharks is converging on Florida.

With the new legislative session next in September, conservation groups are pushing for measures at both the state and federal level to ban one of the largest threats to the shark population – the fin trade.

Between 100 million and 200 million sharks are killed every year. An estimated 73 million of those are killed for their fins.

“The shark fin trade is a global market for shark fins,” Trish Albano, a shark researcher at the University of Miami’s Rosensteil School of Marine and Atmospheric Science, told NBC 6 South Florida. “The shark fin is being used to make shark fin soup.”

MASSACHUSETTS: Shark detection technology gets quiet rollout on Outer Cape

August 5, 2019 — With little fanfare, shark detection technology on Cape Cod took a small step forward last month off Newcomb Hollow Beach, the site of last year’s fatal shark attack on body boarder Arthur Medici.

Cape Cod and regional public safety officials have been hoping for years to employ a kind of souped-up version of what they already have, an acoustic receiver attached to a buoy that can not only detect signals from tagged great white sharks but relay an instantaneous alert to lifeguards and beach administrators.

One such device was deployed off Newcomb Hollow, state shark researcher Gregory Skomal said, and two more to be placed at Head of the Meadow Beach in Truro and at Nauset Beach in Orleans.

Scientists Are Trying to Keep Sharks From Commercial Lines

August 5, 2019 — Scientists at the Virginia Institute of Marine Science in Wachapreague are doing research this summer that could result in a way for commercial fishermen to keep sharks from interfering with their fishing lines.

VIMS Eastern Shore Lab has the advantage of being right on the water and near the last undeveloped stretch of barrier islands on the East Coast.

“There is only one lab in all of Virginia that has running seawater, which you need to keep sharks,” said VIMS scientist Richard Brill.

That lab is in Wachapreague.

More than 150 great white shark sightings logged off Cape Cod, Massachusetts, since June

August 5, 2019 — There have been more than 150 great white shark sightings since June off the coast of Cape Cod, Massachusetts, a popular East Coast vacation spot, according to scientists.

This week alone, more than 20 great white shark sightings logged off the Cape, prompting three days of beach closures in a row beginning Tuesday.

The Atlantic White Shark Conservancy’s sharktivity app indicates that there have been more that 161 shark sightings off the coast of Massachusetts since June 1. The same shark can be spotted multiple times, scientists note.

Atlantic Spiny Dogfish Benefits from Sustainable Shark Management

August 2, 2019 — The following was released by NOAA Fisheries:

Wielding two venomous spines and growing as long as 4 feet, Atlantic spiny dogfish can often be seen hunting prey in dog-like packs (hence the dog-like name). Today, these little sharks are the most commonly caught and exported U.S. shark species, but that wasn’t always the case.

Spiny dogfish were once one of the most abundant shark species in the world. They were historically considered a nuisance by many fishermen who believed they ate young Atlantic cod and other high-priced species. However, NOAA Fisheries shark scientist Dr. Tobey Curtis said studies of spiny dogfish diets do not support this perception.

Smaller spiny dogfish tend to feed primarily on crustaceans, while larger dogfish eat jellyfish, squid, and schooling fish. Cod, red hake, goosefish, other spiny dogfish, larger sharks, seals, and killer whales all prey on dogfish. Dogfish also have a habit of getting caught in fishing nets due to their small size, resulting in bycatch.

Great white sharks rule Cape Cod waters

August 1, 2019 — Scientists have begun a new research program around Cape Cod in Massachusetts, focusing on movements and behavior of a growing great white shark population, to reduce the increasing potential for interactions with humans.

Atlantic white sharks are the center of attention in the frenetic Cape Cod summer tourism season, as the combined resurgence of their primary food source, gray seals, and the shark population plays out.

The shark season has been early and active, with numerous sightings and several temporary beach closings ordered as a result in July. It’s been just one year since two shark attacks off cape beaches resulted in the first recorded fatal shark attack in Massachusetts since 1936 when a body board rider was killed.

Barnstable County towns have invested in better warning and communication systems, pre-position first aid trauma kits and equipment to be prepared for another attack. One Nantucket-based group even asked local officials to seek federal action for changing the seals’ legal status under the Marine Mammal Protection Act — an echo of demands years ago in New England and Canada for the animals be culled in hunts.

Instead the Massachusetts Division of Marine Fisheries, the nonprofit Atlantic White Shark Conservancy based at Chatham, Mass. and other partners are in a new push to expand their study of white shark movements and behavior, with an emphasis on improving public safety in nearshore waters and channels where the animals hunt seals.

Our Fishing Is Driving Sharks To Extinction

August 1, 2019 — In a world so big, it may be unfathomable to think our human touch has reached every corner. Yet our mentality of overabundance has leeched and tainted even the remotest parts of our oceans. In a ground-breaking Nature report, a team of more than 150 scientists have come together to showcase just how our major high seas fishing activities impact sharks.

There are over 500 species of shark worldwide and many large ones call the open ocean home. While it may be hard for them to find food in this vast blue desert, our technology has made it so we can find large quantities of it in very little time. Fishing fleets are the biggest threat to all sharks, but especially large ones as they account for over half of all identified shark catch globally in target fisheries or as bycatch. This unsustainable trend has paved the way for declines in some population numbers, like the regional declines in abundance of shortfin mako shark (Isurus oxyrinchus).  While scientists knew that sharks and fishing fleets shared the same areas, they didn’t know just how much fishing takes place in areas where sharks aggregate. This was crucial evidence needed to fight for catch limits in the high seas, where there is currently little to no management or enforcement for sharks.
