Save Our Fins Event – a big success!

Scubafish Shark Fin Race

In July 2010 Ko Lanta’s Dive Centres and Fish4Divers organised a ‘Save our Fins’ 3-legged fin race to help raise awareness about shark finning (and much needed funds) to help the Shark Trust continue their constant fight to protect our ocean’s sharks.

Shark Fin Race

For the event we asked divers, locals and holiday-makers from all over Ko Lanta to grab a buddy and join us for a three-legged fin tournament, to help raise awareness about shark finning. We were delighted and overwhelmed by the hugely positive response and fantastic turnout to the event. Nine Dive Centres, White Rock Resort, Opium Bar and even the Thai Diving Association joined fins to sponsor the event, and over 80 people from all over the island came to take part in the race, spectate or have a giggle at the fin-wearing racers. It even became a traffic-stopping event with cars and motorbikes pulling up to see what was going on.

Winner Luke and Ben from Blue Planet

Twelve, 3-legged teams raced in 2 heats, with first and second place winners from each heat competing for overall first place in the final. Race winners, Luke and Ben from Blue Planet Divers, used questionable, but dramatic shark-like tactics to secure their win. Reports of them beating other contestants with a giant home-made Leopard shark fin have been confirmed with video evidence that can be viewed on Facebook or You-Tube.

Fin Race Action

Donations for the Shark Trust are still being counted, but if enthusiasm and support for this event had a monetary value, this was certainly a huge success and will be remembered, and hopefully repeated, for a long time to come.

Narima Diving and Scubafish will continue to support events and causes that raise awareness about Shark Finning and other environmental issues facing our oceans and marine life.

Safe Our Fins Event – Join us to save the sharks!

Shark Fin Race

Grab a buddy and join us for a three-legged fin tournament, to help raise awareness about shark finning. We’ll meet on 17th July, 5.30pm at White Rock Resort, Klong Nin Beach.

The event is organised by Scubafish, Narima Diving, Blue Planet Divers and Fish4Divers.com. Posters and shark-fin shaped leaflets in Thai and English will be distributed around the island the publicize the event and Ko Lanta’s dive centres come together to form teams and enthuse their divers to take part. We’d like to invite all divers, locals and holiday-makers from all over Ko Lanta to grab a buddy and join us for a three-legged fin tournament.

White Rock Resort & Mr. Bean are supplying free beer and curry for the participants. And we guarantee lots of fun!

Shark finning refers to the removal and retention of shark fins and the discard at sea of the carcass. The shark is very often still alive when it is tossed back into the water. Unable to swim, the shark slowly sinks toward the bottom where it suffers predation from other fish, starves to death, dies from blood loss or suffocates and drowns, since most sharks need to keep moving to force water through their gills for oxygen. Sharks can take hours or even days to die after being finned.

Fishermen are mainly interested in the fins because shark meat is of low economical value and this conserves room in the hold. Up to 99 per cent of the shark is thrown away, a process as wasteful as slaughtering an elephant for its tusks.

Shark Fin Race

Shark fins are used as the principal ingredient of shark fin soup, an Asian delicacy which is often served at wedding celebrations so that the hosts can impress their guests with their affluence. Shark fin itself is tasteless, it just provides a gelatinous texture for the soup which is flavoured with chicken or other stock. It has also been shown to contain high levels of mercury which is detrimental to our health. Many people, especially the consumers, are unaware of the suffering that finning causes.

Sharks’ life history makes them vulnerable to exploitation. Sharks take between 7 to over 20 years to reach maturity, and produce few young over long lifetimes meaning that it takes populations a long time to recover once depleted. Fishermen report that sharks are getting smaller because they are not being given time to mature.

Sharks are “apex” predators, eco logical stablisers, when they are removed from the ocean the entire eco-system suffers.

Please say “No” to Shark Fin soup and join our three-legged fin tournament to show your support for sharks!

Orientation day in the SSS Recompression Chamber in Phuket

SSS Recompression Chamber Phuket

Divemasters and Instructors of Scubafish and Go Dive Lanta used the Low Season 2010 to get an insight into the work of a real recompression chamber. The SSS Recompression Chamber Network in Phuket offers free orientation days once a week during the low season. The orientation includes an overview of the chamber facilities and setup, recognition and management of Decompression Sickness, a pre-dive briefing and an actual dive down to 60ft in the recompression chamber. There is also plenty of time to ask questions to learn more about the various types of Decompression Sickness.

SSS Recompression Chamber PhuketDecompression Sickness (DCS) is the result of inadequate decompression following exposure to increased pressure during diving. In some cases, the disease is mild and not an immediate threat. In other cases, serious injury does occur. When this happens, the quicker the treatment begins, the better the chance for a full recovery.

During a dive, the body tissues absorb nitrogen from the breathing gas in proportion to the surrounding pressure. As long as the diver remains at pressure, the gas presents no problem. If the pressure is reduced too quickly, however, the nitrogen comes out of solution and forms bubbles in the tissues and bloodstream. This commonly occurs as a result of violating or approaching too closely the diving table limits, but it can also occur even when accepted guidelines have been followed.

Bubbles forming in or near joints are the presumed cause of the joint pain of a classical “bend.” When high levels of bubbles occur, complex reactions can take place in the body, usually in the spinal cord or brain. Numbness, paralysis and disorders of higher cerebral function may result. If great amounts of decompression are missed and large numbers of bubbles enter the venous bloodstream, congestive symptoms in the lung and circulatory shock can then occur.

SSS Recompression Chamber PhuketSymptons of Decompression Sickness include unusual fatigue, skin itch, pain in joints and/ or muscles of the arms, legs or torso, dizziness, vertigo, ringing in the ears, numbness, tingling and paralysis, shortness of breath. You can also recognise DCS by checking for the following signs: skin may show a blotchy rash, paralysis, muscle weakness, difficulty urinating, confusion, personality changes, bizarre behavior, amnesia, tremors, staggering, coughing up bloody, frothy sputum, collapse or unconsciousness.

Symptoms and signs usually appear within 15 minutes to 12 hours after surfacing. But in severe cases, symptoms may appear before surfacing or immediately afterwards. Delayed occurrence of symptoms is rare, but it does occur, especially if air travel follows diving.

SSS Recompression Chamber PhuketRecreational divers should dive conservatively, whether they are using dive tables or computers. Experienced divers often select a table depth (versus actual depth) of 10 feet (3 meters) deeper than called for by standard procedure. This practice is highly recommended for all divers, especially when diving in cold water or when diving under strenuous conditions. Computer divers should be cautious in approaching no-decompression limits, especially when diving deeper than 100 feet (30 meters).

Avoiding risk factors like deep and/ or long dives, exercise at depth or after a dive will decrease the chance of DCS occurring. Exposure to altitude or flying too soon after a dive can also increase the risk of decompression sickness.

Decompression Sickness could affect divers every day. Fast recognition is probabaly the most important key for a full recovery. Joining orientation days like these certainly helps to raise the awareness of the risk of decompression sickness.
