Record-Breaking Hammerhead Landings Deadly And Possibly Illegal, Says Marine Biologist

Published

on

Last month a 21-year-old man in Florida made international headlines for snagging a 13-foot hammerhead while fishing off the pier at Lauderdale-by-the-Sea. After his friend’s line bent hard and the huge fish was pulled in closer, Ryan Bolash dragged the shark onto a beach full of stunned onlookers.

“It was flailing around, everything like that,” one witness later said. “It was really cool.”

The famous snag was only the latest in a spate of recent high-profile hammerhead catches. But according to one marine biologist, the sharks’ lives were in danger and the fishermen were probably breaking the law.

In March a group of Florida Atlantic University students made headlines when they caught a 14-foot, estimated 700-pound hammerhead (and posted a YouTube video of the ordeal, now viewed more than a million times), and in February a man was featured on local television after winning a South Florida fishing tournament with his hammerhead catch.

All the fishermen expressed concern for the animals’ well-being and released the sharks. “They’re an amazing creature,” Bolash said. “I don’t know why anyone would want to hurt them.”

But the fishers also struggled for an hour or more with the animals to reel them in — hammerheads are renowned fighters — and took photos and measurements before releasing the sharks. Keeping the animals on land even for a few minutes can prove fatal, says a University of Miami marine biologist. And thanks to a 2012 law aimed at protecting the species — which is endangered — it’s also illegal.

“Think about if we were holding your head underwater for several minutes while scuba divers were taking a picture,” says David Shiffman, the biologist. “You’re not adapted to survive in that world.”

Of shark species, Shiffman says, hammerheads have among the highest stress responses to being caught. They fight instantly and vigorously, which makes the shark popular with fishermen looking for an adrenaline rush. But it also means hammerheads are more likely to die from the stress and fatigue of a protracted battle with a fishing line, even if they’re released promptly once they’re finally reeled in.

Shiffman is particularly miffed at those who brag of hours-long “epic fights” to bring in the hammerheads. “The ‘fight’ is the animal literally trying not to die,” he says. “[It’s] putting every bit of energy it has into not being killed.”

There’s no reliable hammerhead count available, Shiffman says, but he estimates the shark’s population has declined by as much as 90 percent since the 1970s. In 2012 the Florida Fish and Wildlife Conservation Commission passed a regulation prohibiting the killing of three varieties, including the great hammerhead, the largest. But the law also prohibits “landing” of the sharks, meaning it’s illegal to bring them ashore unless they are “immediately returned to the water free, alive, and unharmed.”

Keeping the hammerheads on the beach to measure them or pose for a picture, Shiffman contends, means the animals aren’t being immediately released, and the stressful fight to reel them in means they’re not left unharmed.

The biologist estimates that in recent years hundreds of hammerheads have been pulled ashore, often during the night or in unpopulated areas where the practice can go unnoticed.

“‘Oh yeah, of course we released it. We don’t want to hurt the animals,'” he said, mimicking the fishermen’s typical response. “But they’re using illegal actions that hurt the animals. Their heart’s in the right place, but their actions need to match it.”

Book Review: The Diver and the Cook – Trapped in 102 Feet of Water

Published

on

book review

Wow! What a story, and what an incredible feat of not only survival for the cook but of the sheer bravery and determination of his rescuers.

It’s an easy read with absolutely no waffle or embellishment and is probably the quickest I have ever read a book from cover to cover. It’s not only a story that will touch the hearts of divers but is also a great read for anyone who has not been to or under the sea at all.

Dived Up Publications announces the release of The Diver and the Cook by Lasse Spang Olsen.

A ship lost. No survivors. A grim recovery mission begins, pushing a team of commercial divers well beyond their comfort zone.

Braving treacherous conditions, saturation diver Nico van Heerden single-handedly combs the cramped, debris-strewn, zero-visibility Jascon 4 shipwreck searching for any sign of the lost crew.

Then, in a scene akin to a horror movie, while exploring a small, isolated compartment, Nico feels a tap on his shoulder. Could someone have survived underwater for over sixty hours?

The Diver & the Cook is the incredible true story of a seemingly impossible underwater rescue. With first-hand accounts, authentic images and detailed reconstructions, author and documentary maker Lasse Spang Olsen brings this gripping tale to life. The book is the result of over four years of work, including intensive interviews, access to previously unknown material, and deep study of conversations and film recorded during the actual incident.

Witness the unwavering determination of the human spirit as Jascon 4 galley chef, Harrison Okene, fights for survival after his ship goes down. Meanwhile, rookie saturation diver Nico van Heerden faces a daunting challenge: spearheading the rescue mission in a perilous underwater environment. With time running out, what rules must the dive team break to save Harrison before it’s too late?

An unprecedented operation, this story provides a unique perspective on the dangers and challenges faced by divers, showing the importance of teamwork and communication in high-risk situations. An incredible survival story against all odds, with an equally surprising aftermath.

Quote from the author, documentary-maker Lasse Spang Olsen:

“There are a whole lot of different versions of this story out there. But I believe that by speaking directly to the key people involved, creating meticulous reconstructions and doing original research we have dug much deeper and got far closer to the truth about the rescue and the sinking than anyone has ever managed to before.”

About the author

Author and veteran filmmaker Lasse Spang Olsen – in a 40+ year career – has participated in stunts and FX on over 600 films, directed eleven features and filmed extensively underwater. He’s led expeditions uncovering historical mysteries like the Flying Enterprise wreck and documented adventures worldwide. He’s also a producer and lecturer. Originally published in Denmark as Dykkeren of Kokken (February 2024), this is his fourth book.

The Diver and the Cook (ISBN 978-1-909455-61-0) is released on 12 November 2024 in paperback and ebook. It is available via online retailers, bookstores, from DivedUp.com and to the dive trade via Nautilus UK.

SCUBAPRO, the world’s premier manufacturer of high-quality scuba diving equipment, introduces its second generation Luna 2.0, an easy-to-read, intuitive dive computer loaded with easy-to-use features and available in two versions, the Luna 2.0 and Luna 2.0 AI with wireless air integration.

Designed for new and casual recreational divers, the low-profile Luna 2.0 sits comfortably on the wrist. Its oil-filled plastic housing helps ensure reliable performance to depths of 120 meters. A large widescreen display features a high-contrast black and white matrix-segment LCD with full-sized characters for easy reading in all dive conditions. An intuitive menu and simple two-button interface lets the diver navigate the system with ease, aided by clearly marked screen prompts. The LUNA 2.0 offers two algorithms – Predictive Multi-Gas Bühlmann ZH-L16 ADT MB PMG or ZH-L16 + GF PURE, plus 21-50% nitrox compatibility and three selectable gasses for open circuit diving. Three dive modes are available – Scuba, Apnea and Gauge – to suit a range of diving activities.

The Luna 2.0 AI (air integrated) offers the same easy-to-use features and functions as the standard Luna 2.0 plus adds wireless air integration. This not only enables to easily monitor ythe tank pressure, it also provides true remaining bottom time (RBT) and allows the air consumption to be factored into the decompression calculation. Also available with the Luna 2.0 AI is an optional integrated heart rate monitor that lets visually track the heart rate and skin temperature to help staying in the personal target zone.

Both Luna 2.0 models include personalized dive management functions like PDIS (Profile Dependent Intermediate Stops) which calculates an intermediate stop based on N2 loading, current and previous dives and breathing mixes, and Microbubble levels that give the option to adjust the level of conservatism in the algorithm to match the individual experience level, age and physical conditioning for a more enjoyable dive.

The soft silicone arm strap offers a comfortable fit on the wrist, plus bungee mounts on the corners of the housing allow for alternate attachment methods. A Bluetooth Low Energy interface enables the download of the dive data to any iOS or Android device or PC/Mac (firmware can be user-updated), and the CR2450 battery is rated for up to two years or 300 dives.
