OCEARCH will be in Australia looking for Tiger Sharks with shark experts from the University of Western Australia later this month.
During the three-week expedition the crew hopes to land 20 mature tigers to tag and collect scientific data.
They plan to start in mid-April at Broome and then head to Rowley Shoals, Ningaloo Reef, Shark Bay, the Abrolhos Islands and then finish in Perth.
Chris Fischer, founder of OCEARCH told Perth Now “What we’ve found when we work around the world is that when you tag these sharks and you open-source the tracking, it gives people things to talk about other than, ‘Oh my God, a shark is within 300 meters of the beach’ or another shark attack.”
He may be correct; one of OCEARCH most loved sharks Lydia has amassed 12.6 followers on Twitter.
Unfortunately, The Australian Fishers Department has only made an exemption for the catching of tiger sharks and rejected an application to catch and tag white sharks.
Instead the Australian authorities have fitted 80 sharks with acoustic transmitters that ping when the shark swims within 400 meters of an acoustic receiver.
The government also implemented a controversial cull program last year. During a three-month trial 172 sharks were caught.
Twenty of the sharks were found dead on the lines, 14 of which were under the 10 ft requirement, fifty sharks over ten feet were shot and killed, even though they were not the targeted great whites.
A total of 90 were found alive and under the 10 ft requirement, so they were tagged and released.
Mr. Fischer said “When you see what’s going on in Australia with various forms of management of the sharks, it just seems like everyone is operating in this really intense mode of fear.”
In my opinion the Fishers department should jump at the chance to have OCEARCH tag white sharks. I have wondered if they are concerned tourism may take a hit if people can see where white sharks are swimming. What do you think? Let us know in the comments.
I don’t know much about the clip, but according to Beqa Adventure Divers it was filmed at Tiger Beach in the Bahamas.
It appears the shark makes three snaps at the free diver. Once at his head
the second as he is getting out of the way
and the third toward his arm.
While the shark isn’t acting in a super aggressive manner, had the shark’s mouth actually made contact with the diver, it could have easily been fatal. Thankfully the diver was able to see the shark and move out of the way.
If more info becomes available, I will update the post.
Dr. Marcus Drymon from the University of South Alabama and Dauphin Island Sea Lab wants to find out how Tiger Sharks are making a meal of backyard song birds.
Since 2010 he has been finding bird remains in the stomachs of tiger sharks, which is strange because the remains are not seagulls or pelicans, but land-based songbirds, woodpeckers, and even doves. One theory is the birds may be attracted to the night lights on oil rigs and then are unable to make their way back to land.
As Principal Investigator for the University of South Alabama’s Shark Research Program, Dr. Drymon has an idea on how to solve this mystery-by tracking sharks. He is hoping to raise $6,800 to purchase four satellite spot tags which will be attached to find of tiger sharks in the northern Gulf of Mexico.
The tags will ping every time the tag breaks the surface, and if it nears an oil rig, it could be a clue as to how the birds are becoming snacks. The top four donors will be able to name a shark, and will have access to that shark’s movements for the duration of the tag’s life. All funds raised will go directly toward the purchase of the tags.
Ultimately, a better understanding of the tiger shark’s diet will aid in the formatting of a more effective conservation and management plan.
“Recent estimates suggest that the global biomass of predatory fish has declined by two thirds over the past 100 years. Understanding the diet of apex predators such as tiger sharks is critical for their management, and for predicting how changes in their populations will impact the resilience of the ecosystems they occupy.”
A humpback whale expired off the New South Wales southern coast. A family was able to capture some nifty underwater shots of a shark grabbing a free meal while helping clean up the ocean. I like how the shark goes horizontal, using its weight for a better bite.
Lacey Webb Martin was snorkeling* in the Bahamas Monday when she was bitten by a shark.
The 34 year old Dallas woman was celebrating her anniversary with husband Britt on their annual trip to Abaco Island.
The couple were snorkeling in around 8ft of water off Tahiti Beach when an eight-foot shark bit her back.
A tooth was left in the would which was originally thought to be from a tiger shark. KYTX reports it may be from a great white.
Britt Martin told Local 10 “She was so calm that I thought she was kidding,” “So I swam over there and she pulled herself up on the boat and she was missing half her back.”
Thankfully she was able to receive medical assistance fairly quickly.
“We pulled her up on the boat and just wrapped her in a tourniquet with towels and, luckily, there was a doctor on one of the other boats from New York and she came over and they radioed the medics.”
She was flown to Memorial Regional Hospital for treatment, where she will be hospitalized for at least three weeks.
“You know, you hear about it on TV, but you just never think, ‘Hey, this could happen to us on vacation,” Mr. Martin said.
Mr. Webb added “She didn’t scream; the doctor said that’s what kept her alive.”
Please keep Mrs. Martin in your thoughts and prayers.
