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.

Global Threat to Sharks Highlighted in Nature Paper Co-Authorized by Mote Scientists

July 31, 2019 — The following was released by Mote:

A new study in the prestigious, peer-reviewed, scientific journal Nature reveals that major high seas fishing activities overlap significantly with important shark hotspots worldwide.

Study partners point out that North Atlantic blue sharks and shortfin mako – the fastest shark in the sea – have on average 76% and 62% of their space use, respectively, occupied by longline fishing  vessels each month, and even internationally protected species such as great white and porbeagle sharks are at risk of bycatch in such fisheries. The study calls attention to the danger of accelerating shark population declines and disappearance of their hotspots, along with opportunities for more sustainable management of fisheries and shark populations internationally.

The study included 150 scientists from 26 countries who combined their knowledge and data from nearly 2,000 satellite-tagged sharks. Co-authors from Mote Marine Laboratory’s Center for Shark Research have tracked white, bull, hammerhead, whale and multiple other shark species with satellite tags over decades of conservation-focused science, some in collaboration with research partner OCEARCH.

NEW JERSEY: New sharks could be visiting the Jersey Shore thanks to climate change

July 31, 2019 — While sharks off the Jersey Shore are nothing new, experts who study the ocean predators say New Jersey’s waters are becoming an increasingly popular destination for unlikely species of sharks.

Ocean-warming climate change is already bringing sharks typically found in southern waters, like bull sharks and blacktip sharks, to New Jersey on a more frequent basis said Thomas Grothues, an associate research professor at Rutgers who studies sharks (he just happens to be a past Shark Week star.)

As the planet continues to warm, this trend is likely to continue, Grothues said.

5 shark attack survivors explain how they made it out alive

July 31, 2019 — A 19-year-old surfer who suffered a vicious shark bite last month was determined to face his fears as soon as his wounds healed.

Not only did Austin Reed return to the ocean just over a month after the attack, he went back to the exact site of the harrowing encounter, North Carolina’s Ocean Isle Beach.

“I went back to the spot where I got bit,” Reed told Willie Geist and Savannah Guthrie on TODAY Wednesday. “I thought that was the best way to get closure.”

Reed was one of five shark attack survivors who shared their stories on TODAY Wednesday.

He was joined by Keane Webre-Hayes, who needed 1,000 stitches after being attacked in California while lobster diving; Tiffany Johnson, a mother of three whose right arm was amputated after she was bitten while snorkeling in the Bahamas; Lola Pollina, who was bitten at New York’s Fire Island last year; and Jonathan Hernandez, who was attacked last month while spearfishing in the Bahamas.

Sharks Have Few Places To Hide From Fishing, Study Shows

July 24, 2019 — Ocean-dwelling sharks often like to hang out in areas that also get frequented by industrial fishing ships, which puts them at grave risk of being caught either for food or as bycatch.

That’s according to a new study in the journal Nature that mapped the activity of 23 shark species and fishing vessels around the globe.

Researchers tracked more than 1,500 sharks with satellite tags and combined that data with information on ship movements taken from safety technology that vessels use to avoid collisions at sea.

“Tens of millions of these pelagic sharks are being caught by industrialized fisheries in areas where there’s little or no management, and some populations have declined as a result,” says David Sims, a U.K.-based marine ecologist at the Marine Biological Association in Plymouth and the University of Southampton.

Fishing vessels can catch sharks accidentally, because their long lines can extend for miles and have more than 1,000 hooks.

Highlighting the Cooperative Shark Tagging Program for Shark Week

July 23, 2019 — The following was released by NOAA Fisheries:

The Northeast Fisheries Science Center’s Apex Predators Program studies the life history and ecology of sharks in the marine and coastal waters of New England and the Mid-Atlantic. In 1962, they began the Cooperative Shark Tagging Program with about 100 volunteer recreational and commercial fishermen, scientists, and fisheries observers. Today they have more than 7000 volunteers contributing data to the Tagging Program.

More than 295,000 sharks, comprising more than 50 species, have been tagged to date. The data from tagging and recapture events have been instrumental in shaping what we know about shark migration and distribution. It also helped to define the essential fish habitat for 38 federally managed shark species. It continues to be used for defining and updating areas designated as essential for shark survival.

Blue sharks (Prionace glauca) are a common pelagic species found in New England waters. More than 122,000 blue sharks have been tagged to date and they’re the most tagged species of shark in our Tagging Program’s database. In fact, they account for 42% of all the tagged sharks recorded in our database and of the more than 122,000 tagged blue sharks, 7% of them have been recaptured at least once.
