The importance of great white sharks; scientific community is testing & tagging sharks off Florida

Jan 30, 2018

There is important research underway right now off the Florida coast.

Researchers fear the great white shark population may be declining, and if that’s the case, lots of other fish species will decrease. That would have a great impact on all of us.

Mary Lee, Hilton, George and Savannah are just some of the eastern seaboard great white sharks that have been on the Ocearch floating lab, and researchers say they need more.

Savannah pinged off our coast a few times in January, including near Port St. Lucie on Jan. 9. Her last known location was near Key West.

“Ship of opportunity for researchers like myself,” Dr. Bob Hueter, a senior scientist at the Mote Marine Lab in Sarasota and chief science advisor for Ocearch.

This is day eight of 25. Ocearch is in the middle of its 31st shark expedition, and Hueter’s 10th. …

Fischer says this is the only ship in the world that can board a great white, test it, tag it and release it without dying.

“The lift really is what makes the impossible possible,” Fischer said.

The scientists on board take samples of the shark. If she’s pregnant, an ultrasound.

They’ll attach a tracker to the dorsal fin. When it surfaces, it’s pinged by a satellite.

Savannah last buzzed our coastline earlier this month.

“She showing us where the nursery of tweener type shark is living and how big that is and we know how to manage it”, Fischer said,

Whites are born at about 4.5 feet and aren’t mature until they’re about 15 feet. Savannah is about 8 feet.

“As you see more and more white sharks in Florida and more and more other species of sharks, you’re going to see more and more fish,” Fischer said.

On this day — we didn’t catch any sharks. They only need one in their 25 days to make their expedition worth it.

The next shark they catch will feature a new transmitter, created by the European Space Agency. It’s never been used on an animal before, but Ocearch says it will provide more data and the battery lasts longer.

The next expedition is set for May, called the Gulf Stream drift starting off the coast of Miami and headed north.

Today, Dutch Vroege Vogels radio told 4 February 2018 is the last day of the expedition, and so far they had not caught sharks; as the sea water this winter is colder than usually, so the sharks are absent from where they are usually. The new tags invented by ESA would be able to provide much more information than the older tags, about depths at which sharks swim etc.

Trump’s fear of sharks helps sharks

The deep ocean is one of the planet’s harshest environments. Here, evolution has taken bizarre turns. The sharks that prowl these waters have been undetected for millions of years…until now.

Reality bites: Trump‘s fear of sharks leads to surge in charity donations

Marine charities say they are benefitting from Stormy Daniels’ claim Trump is terrified of sharks

‘Trump wants to kill all sharks’

This 2016 video says about itself:

“Love” and “affection” are terms not commonly used to describe encounters with large sharks, but they’re used repeatedly by Jim Abernethy to narrate his recent get-together with a large tiger shark known as Tarantino. The special reunion at Tiger Beach in the Bahamas was videotaped and footage shows Tarantino swimming into the arms of Abernethy, and seeming to crave his caresses much like an affectionate dog craves those of its owner after a prolonged absence. As Abernethy and the shark are swept down current, he returns to the camera and Tarantino follows, again swimming into his arms. This happens twice in the footage.

“I could tell she had missed it”, Abernethy says of an apex predator he refers to as an “old friend.”

To be sure, Tiger Beach is a special place, known as a destination where close encounters can be enjoyed in what many consider to be a relatively safe environment.

The predators are fed during commercial dive operations, and many distinctive sharks have been given names. Veteran divers such as Abernethy, who runs Jim Abernethy’s Scuba Adventures, claim to have developed special relationships with some of those sharks.

Though there are bound to be critics of people “tempting fate” with such close interactions, Abernethy, who was once bitten by a lemon shark, was hoping his footage would send a message. “I wish there was some way that I could get the world to see what these beautiful creatures are really like”, he says, “so we could end the needless slaughter and keep our oceans healthy, not only for them but for our own existence on the planet.”

From daily The Independent in Britain today:

Trump thinks all sharks should die, according to Stormy Daniels

Donald Trump’s alleged extra-marital activities have been a source of discussion lately, following claims from an adult film actress that the pair had a sexual relationship before his Presidency.

Thirty-eight-year-old Stormy Daniels, whose real name is Stephanie Clifford, spoke to In Touch Magazine in 2011, but the interview remained unpublished until Wednesday.

The interview contained explicit details of the so-called affair, which reportedly began in 2006.

In one extract, she recalls having dinner with Trump in his room – and watching a shark documentary. She said:

“… He is obsessed with sharks. Terrified of sharks. He was like, ‘I donate to all these charities and I would never donate to any charity that helps sharks. I hope all the sharks die.’ He was like riveted. He was like obsessed. It’s so strange, I know.”

… His fixation with sharks however, has been well documented.

Trump’s obsession with sharks is reminiscent of the fictional character Captain Hook‘s obsession with crocodiles.

Maybe a good idea to take cardboard sharks to the next anti-Trump demonstration?

Tiger shark Andy’s long travels

This 31 August 2017 video is about tiger shark Andy.

From Nova Southeastern University in Florida, USA:

Tagged tiger shark proving unstoppable

January 11, 2018

Summary: For more than a decade, researchers have been tagging and tracking sharks in order to study their migratory patterns and more. One tiger shark – Andy – is now the longest-ever tracked tiger shark, providing years worth of data for researchers.

Not freezing temperatures or nor’easters or Hurricanes Harvey, Irma, Jose or Maria can stop “Andy”, a tiger shark tagged in Bermuda by scientists from Nova Southeastern University’s (NSU) Guy Harvey Research Institute (GHRI) in 2014. Travelling approximately 37,565 miles off the eastern coast of the United States and around Bermuda, the Bahamas and Turks and Caicos, Andy is now the longest tracked tiger shark on record and shows no sign of slowing down. He’s been going for more than 1,240 days.

“We are delighted with how long Andy has reported data, which has tremendous value for us as researchers,” said Mahmood Shivji, Ph.D., the director of NSU’s GHRI and a professor in the university’s Halmos College of Natural Sciences and Oceanography. “This amazing, nearly three and a half year track is revealing clear repeated patterns in the shark’s migrations between summer and winter.”

More than 150 sharks, including tigers, makos and oceanic whitetips, have been tagged by the GHRI in the last decade. The data collected is used to study the migration patterns of these incredible creatures. Andy and many other GHRI tagged sharks can be followed online in near real-time at nova.edu/sharktracking.

“Tracking the migration patterns of sharks, like Andy, for extended periods of time allow us to better understand their behavior and habitat utilization, resulting in better knowledge on how to manage the species”, said world renowned artist and Guy Harvey Ocean Foundation (GHOF) Chairman Guy Harvey, Ph.D.

According to a paper published in the most recent ICES Journal of Marine Science by Shivji and his colleagues, tiger shark migrations are heavily influenced by a shark’s physical characteristics (i.e. size, age) and environmental variations (i.e. water temperature, prey availability). This study, funded by the Guy Harvey Ocean Foundation, NSU’s GHRI, the Shark Foundation (Hai Stiftung) and the Bermuda Shark Project, reveals not only the environmental factors driving these massive migrations by tiger sharks but also highlights how the different age groups behave. This information could prompt fisheries managers to reevaluate how best to protect this near-threatened species.
