Ocean Conservation and Culture: one does not have to look far to find conflict

Ocean conservation requires not only an understanding and appreciation of the various worldwide marine ecology and the species that contribute to their existence; an understanding of the specific environmental threats to ecosystems and specific sealife, whether directly man-made or occurring naturally through cyclical patterns. We also need to understand the cultural histories that formulate the attitudes of people regarding the ocean and its future.

In the case of endangered species, likes sharks, whales, tuna, or a wide range of commercially harvested animals, we often turn towards Asian or developing island nations and the long-standing culture steeped in the use of seafood. We wring our hands when considering how these societies can appear to be so singular in purpose and dedicated to consuming natural marine resources - both locally and in international waters.

To be sure, these nations have long cultural histories intertwined with the bounty of the sea and it is a challenge to get them to objectively look at what is happening to their treasured ocean resources before it is too late. But internal progress is being made, although it is a slow process. "Outsiders" can have only so much of an effect; much has to come from self-realization within the culture itself. We see this with anti-shark positions being taken by citizens in Taiwan while a healthy trade in shark fins continues. Japan's harvest of whales and dolphins continues while the consumption of their meat is declining. These conflicting positions represent the achingly slow process of transforming a society to a new way of thinking.

Often, one does not have to travel far to find these same dichotomies at work. In the United States, take the State of Florida for instance. Surrounded on all sides, except for its northern border, by ocean, the "Sunshine State" has a long history with the sea and, in light of today's environmental concerns, we see a culture that is in flux with wasteful attitudes or activities colliding with conservation.

Four recent news articles highlight how Florida can have one foot in the past and one in the future. Reported in Ocean City Today, the 31st Annual Ocean City shark tournament concludes today. This three-day event brings in sportfishermen hungry to catch the largest or heaviest shark in the hopes of winning trophy money that can run into the tens of thousands of dollars. Sportfishing is not only part of the societal fabric of Florida, it's also big business, so the likelihood that it's going to go away anytime soon in deference to overfished species like sharks, tuna, billfish, or other game fish is fairly remote.

As reported in Ocean City Today,
"The Ocean City Shark Tournament is the second of two fishing competitions that allow anglers to accumulate points toward the “Ocean City Sharker of the Year” title. The first event was Mako Mania, which took place June 3-5. Divisions for the event, which has become one of the largest shark tournaments on the East Coast, are: mako, open (threshers and blue shark only), release, bluefish, tuna and dolphin."

As much as shark advocates abhor these shark tournaments, within that listing of categories for the Ocean City Shark Tournament lies one ray of hope: the "release" category. The tournament directors are working to promote catch-and-release of sharks as opposed to bringing in dead ones. And they are trying to facilitate a change in attitude by using bait that is tantalizing to the human species; more trophy money is being diverted to catch-and-release prize categories based on species, size or number. Sure, I would be the first to say let's put an end to all shark sportfishing tournaments tomorrow, but that would be an easy pronouncement for me, coming from California where such events mostly don't exist. But to Florida and its long-standing history in sportfishing, baby steps are required.


However, it would appear that progress towards all catch-and-release is continuing. The Blacktip Shark Shootout, a two-day event which concludes today, has adopted an all catch-and-release format.

As reported in the St. Petersburg Times,
"Shark, like tarpon, could be the next great catch-and-release fishery. Every angler knows that if you catch a fish and kill it, you've got dinner. But if let it go, it can be caught again and again. 'And they are pretty hardy,' {charter captain and tournament co-founder, Joel] Brandenburg said. 'Sharks put up a great fight, and after you release them, they will swim off as if nothing ever happened.'" Now, there are plenty of shark researchers who might want to argue that last statement, but that's a fisherman talking - albeit one who is making an effort to change the way things have been done for years.

However, attitudes about sharks as a food source still persist, and not just overseas in Asian restaurants and marketplaces. NaplesNews.com ran an article on Friday titled "Locals attack shark, buffet style at CJ's on the Bay." It seems that a popular local eatery is heralding in the summer with Loco for the Locals Luau, a Hawaiian island-style barbecue, and rather than use the more traditional roasted pig as the main course, this year the restaurant decided on a whole shark.

“We wanted to do something for our local customers as well, customers that may or may not be members of the Chamber [of Commerce, which held a prior event using roasted pig],” Chef Laura Owens said. “We threw some ideas around and I said, ‘lets roast a shark.’ We might be setting some new ground.” Well, I sure hope not. In fact, it's a slap in the face to Hawaiian culture to use the concept of a luau and, at the same time, roast an animal that is revered throughout Hawaiian tribal history.

However, while there is not a widespread understanding as to the perilous conditions to which shark populations are faced, even in the waters off Florida, progress is being made by Florida regulatory agencies to better protect more species of sharks that have been the target of sport and commercial fishermen for decades. KeysNet.com reports that the Florida Fish and Wildlife Conservation Comission is considering protections for tiger sharks and hammerhead sharks - two species that have been popular with sportfishermen over the years and whose numbers have noticeably declined.

According to Neil Hammerschlag, shark expert from the University of Miami, "Tiger sharks and hammerheads do not reproduce often or quickly, and both are highly prized for their fins for use in shark-fin soup. The pregnant animals come into shallow water to give birth, where the pups can find food and protection from other predators. That tends to make them very vulnerable to fishing. Studies have shown that taking even a few large individuals can have a big effect on the population in a local area."

With already 22 shark species protected in Florida, ranging from great whites to smaller Caribbean reef sharks, a prohibition on landing tiger and hammerhead sharks would not necessarily impact the sportfishing industry, according to Christy Johnson of SeaSquared Charters.

"We do catch and release for big sharks," she said. "I don't know anybody who takes the bigger sharks, except maybe trying for a mako."

So, one does not have to travel far to find conflicting attitudes about sharks or other dwindling fish stocks and what needs to be done about it. Progress is being made but old habits and cultures die hard. It will take patience and persistence on the part of those who recognize the need for immediate steps to preserve our natural resources while accepting the fact that some will need to come kicking and screaming - or may never come around at all.

Shark Physiology: shark tournaments provide researchers with specimens and a moral dilemma

For marine biologists to better conserve and protect the creatures of the sea, they must understand them - their behaviors, their lifestyles, their physiology. To understand them from the inside out means having access to specimens for dissection and this poses one of the great moral scientific dilemmas: having to catch and kill the very animal you hope to protect.

Can this be done responsibly? Are there animals whose internal structures have been studied enough? Are there others resources for specimens available? In many cases the answer is "yes" but not for all. Sharks are one example. There's still much that is unknown about the inner workings of these important predators, but sharks decompose quickly so sharks found dead in the wild are not ideal for study. The same can be said of sharks commercially caught as bycatch or, if commercially sought after, that are immediately processed.

An article in the Cape Cod Times caught my attention as it addressed this issue by examining how researchers use shark tournaments as a means to gain access to suitable shark specimens. The article details how researchers from NOAA and other universities take advantage of the large, mature sharks that are caught to make quick dissections of their internal organs for study. The article is accompanied by a video showing the researchers at work during Massachusetts's long-running (and notorious to many shark advocates) Monster Shark Tournament.

I found the article and video to be very disturbing. Disturbing because it plays to that scientific moral dilemma that many shark advocates just don't like to think about. And for good reason. A 200+ pound mako is hoisted by its tail and brought onto the dock. People are commenting about how beautiful it is with it's cobalt blue body and sleek shape. It pained me to see it.

A large crowd is gathered to watch the festivities of sharks being hauled in. Is there a macabre fascination in seeing the infamous malevolent predator hanging unceremoniously by its tail; a vindication that, in the end, man conquers all? Fishermen are making toasts to their trophies, hoping to gain rewards - sometimes financially sizable whether offered legally or otherwise - and brandishing justifications that the shark meat will be provided to those in need. I can just see the child of a low-income family calling out, "Momma, mako steaks tonight!" Oh boy, shark fin soup - a favorite of the projects! Right. I get angry even as I write this.

But then there is the other side of the argument. The researchers, who are unable to afford boats and crews to go on selective fishing expeditions, are at least afforded some sort of access to fresh specimens for study. Tournaments that set specific rules regarding species, size and weight (favoring older, more mature sharks) garner a measure of favorable PR by providing researchers with the opportunity to do on-site dissections.


"While scientists can get some sharks from fishermen who catch them while targeting other species or from research cruises, large, sexually mature sharks are mainly seen only at tournaments. [NOAA biologist Lisa] Natanson credits tournaments such as the one in Oak Bluffs for welcoming researchers and for encouraging fishermen to land only large animals. Penalties are assessed for landed sharks that are under the weight limit, which is between 200 and 250 pounds, depending on the species.

'Without these tournaments, we'd have to go out and hire a boat and kill them ourselves, and that would be expensive,' said Greg Skomal, the state Division of Marine Fisheries' shark expert. Tournaments also offer college students the chance to do research necessary for advanced degrees. Skomal did his thesis on blue sharks with information gathered at shark contests."

Taking stomachs, intestines, livers, and other tissue samples, there have been some telling results ranging from parasites to diseases. As an example, the Cape Cod Times article sites three forms of cancer that have been found in adult shark specimens.

Shark advocates take note: CANCER HAS BEEN FOUND IN SHARKS, which debunks the belief that sharks resist cancer - one of the foundations behind the demand for shark products as homeopathic cures.

But still, I am troubled. There has got to be a better way. I support the efforts of organizations like the Shark Free Marinas Initiative, which gets marinas to cooperate by banning sharks from
their docks and promote catch-and-release techniques. And researchers have taken advantage of catch-and-release tournaments to take blood and tissue samples, and tag sharks with transmitters before the shark is released at sea. Recognizing that an outright ban of all shark fishing is unlikely, the Shark Free Marinas Initiative is taking an important incremental step forward and away from senseless slaughter for the sake of a trophy kill.

However, for scientists, the need for whole specimens for dissection is still there, as we are continually learning more and more about these important but threatened ocean animals. It is a dilemma that is not lost on the scientists, as they have ambivalent feelings, too.


"While she [University of Hartford biology professor, Joanna Borucinska] appreciates the information she is able to glean from tournaments, Borucinska said she would not be saddened if they went away. The crowd cheered when a big thresher shark was hoisted overhead. But the sight brought her no cheer.

'I never get excited (about seeing a shark on display), especially a big one,' she said. 'I get sad.'"

Professor, you're not the only one.

Guy Harvey Ultimate Shark Challenge: combines research with catch-and-release event

RTSea has been a supporter of the Shark-Free Marinas Initiative (SFMI), which takes an incremental approach to re-educating sport fishermen as to the value of living sharks - as opposed to dead, trophy animals - through the use of catch-and-release techniques. While it would be great to have sport fishermen stop fishing sharks altogether, such an all-or-nothing approach would not find a receptive audience, and so the SFMI transitional strategy has found support from many participating marinas and organizations like the Humane Society of the United States.

Another SFMI supporter, the Guy Harvey Ocean Foundation, conducts a major shark fishing tournament that is not only a catch-and-release event, but also works with research organizations like the Mote Marine Laboratory. At the start of this year's Guy Harvey Ultimate Shark Challenge, a large female bull shark was tagged and it's location is being regularly tracked. This kind of data allows researchers to better understand the shark's travel/migratory behavior and what risks it is exposed to as it travels through various territorial waters - meaning various commercial shark fishing areas.

Here's is a recent update posted by SharkDivers:

Guy Harvey Ultimate Shark Challenge - Tagged Shark Moving Fast

Monday, May 10, 2010

The Guy Harvey Ultimate Shark Challenge
represents a radical change in shark tournament modeling.

Combining shark research and best shark fishing practices the ultimate goal for this tournament is to promote "change from within" the sport-caught shark fishing industry.

A recently tagged female bull shark (perhaps gravid) is now making tournament shark fishing history in Florida waters as she reports her position to Mote Marine Labs and waiting researchers.


Background

On the first day of the Guy Harvey Ultimate Shark Challenge (May 1, 2010), a large bull shark (Carcharhinus leucas) was caught by tournament competitor Bucky Dennis. This adult female was possibly pregnant and an ideal candidate for satellite tagging by Mote Marine Lab's research team. The tag was attached to the shark's first dorsal fin such that it would be able to transmit whenever the shark was at the surface of the water. These transmissions provide precise location and movement information that will contribute to our understanding of the habitat preferences of this important marine predator.
