Information on the marine wildlife found at Gansbaai

The area presents a variety of sceneries whether geographical, geological, faunistic or floristic… Africa is famous for its Big Five but Gansbaai proudly presents Big Six and Seven represented by the Great White Shark and the Southern Right Whale.

About five miles offshore, a small group of islands and reefs owe their international fame to the most wonderful and feared marine predator: The Great White Shark. Dyers Island is named after Samson Dyer, an American Negro who came to the Cape in 1806, and who lived on Dyers Island where he collected guano.

Dyer Island is an ornithological nature reserve for many species of marine birds, among which a colony of 7000 Jackass Penguins. Adjacent to the main island of Dyer, is Geyser Rock, a smaller but much louder island: a permanent colony of 30 to 40 thousand Cape Fur Seals resides on that rock. In between both islands, is a channel which is renown worldwide as “Shark Alley”. The waters surrounding Dyer Island represent The Best place in the world to observe, encounter and dive with this magnificent animal.

From June through December, the Southern Right Whale can be easily observed from the shores. De Kelders is probably the best place worldwide to observe these gentle giants swim within a few meters off the rocky shore. In December, these whales start their migration to the Antarctic waters to feed until the next autumn.

Whale watching can be done out of Gansbaai Harbour, please

Preparing For Scuba With Scuba Diving Lessons

In today’s world, where ordinary citizens and adrenalin-junkies alike are equally capable of chasing adventure, we turn to lessons to make sure we have the appropriate skills. We have lessons for golf, tennis, dance, and any other activity or hobby that can summoned to mind. But for those activities that come with risk, lessons become even more important. Subsequently, those who are interested in scuba diving should always begin with comprehensive scuba diving lessons.

If you are in good health, you can scuba dive. And with proper scuba diving lessons you can do so safely to ensure you get the most enjoyment out of your experience as possible. Finding scuba diving lessons is relatively easy, as scuba diving continues to rise in popularity. Luckily, the availability of lessons does not in any way depend on your proximity to the ocean. Scuba diving lessons are taught in indoor pools which gives the instructor maximum control and eliminates the variables that can easily arise in open water. For students, scuba diving lessons should be confidence building and the best way to achieve this confidence is by mastering your technique in a confined and controlled environment.

In most cases, however, scuba diving lessons actually begin with comprehensive classroom instruction where students are given the basics of the scuba diving technique. Only when the instructor is comfortable that all students completely understand scuba techniques – and the reasons behind them – will you enter the pool. In some cases, equipment can also be rented for scuba diving lessons – an enormous benefit for those who are delaying the purchase of pricey equipment until they receive scuba certification.

Pool instruction during scuba diving lessons offer students the opportunity to put those classroom lessons into use, practicing techniques over and over until they are comfortable. It is essential that these systems are mastered; scuba diving can be dangerous if not done properly and with full respect of the equipment and the water.

There are scuba diving lessons that are offered for children and adults separately. Be sure to research any instructors or instruction facilities to ensure that they are reputable and experienced in training.

Upon successful completion of your scuba diving lessons you will be certified for scuba diving; and you will be well on your way to enjoying a lifetime of adventure and exploration.

Identifying Sharks in the Maldives

There are over 20 species of shark living in the Pacific waters around the Maldives, of which only two present any danger to scuba divers. The others, and even the possible aggressors, are indeed some of the Maldives greatest diving attractions. In fact, ask any diver what the coolest thing he’s ever seen underwater and he’ll probably tell you it was some kind of shark.
The following is a short guide to the sharks of the Maldives together with photos and descriptions to help you recognize them.

Whale Shark

The highlight of most divers’ careers, the whale shark is the largest fish in the water, measuring up to 40 feet long. The shark is grey with very distinctive white spots all over his back. This shark is not aggressive and poses no danger to divers. On the contrary, they are very docile creatures that will allow you to swim close to them.

Tiger Shark

The Tiger Shark is the second largest predatory shark in the world, after the Great White. It is also the second most aggressive shark when it comes to attacking humans, although in Hawaii, where most Tiger Shark attacks occur, there is rarely more than one a year. The Tiger can be identified by his tiger-like stripes on his upper body and sheer size – Tiger Sharks measure up to 9 feet long. To see a Tiger Shark while diving is a real treat, but divers are well-advised to swim away from the shark quietly and without panicking.

Hammerhead Shark

One of nature’s most unusual creatures, the Hammerhead Shark is an amazing beast to see. There are nine hammerhead species already identified (the ninth specimen was identified in South Carolina in 2006), of which three can be dangerous to humans, although shark attacks by hammerheads are almost unheard of. Hammerhead Point, also known as Madivaru Corner, is a dive site in Rasdhoo Atoll, Maldives, where Hammerheads pass by the reef wall early every morning, along with a variety of large deep-water fish. This breathtaking dive is a must-see for any diving enthusiast in the Maldives.

All other shark species in the Maldives pose no threat to humans, but all the same, they should be treated with respect to ensure utmost safety.

The White-Tip Reef Shark is one of the most common sharks to be seen in the Maldives. It is a grey shark with a white tip on its dorsal fin. The white-tip is most active at night, and as the name suggests, it is most commonly found around the reef.

The Grey Reef Shark is also fairly common, and popular among divers. A few years ago, scuba divers gathered around the reef to feed and watch the sharks, but this practice has now been cancelled since there was too much damage to the coral reef.

The Oceanic White-Tip Shark is abundant in the Maldives water, but it is rarely seen by divers since it spends most of its time out in the ocean, away from the reef.

Other sharks that scuba divers might see around the Maldives include the Zebra Shark, Snaggletooth Shark, Silky Shark, Silvertip Shark, Bignose Shark, Tawny Nurse Shark, the Sliteye Shark, the Thresher Shark, the Blue Shark and the Shortfin Mako. Until recently, the only shark protected in Maldivian waters was the Whale Shark. However, on March 9, 2009, a law was passed banning all shark fishing in the Maldives. Conservationists are very optimistic that this will dramatically impact the shark populations around the Atolls.

Shark Cage Diving in Cape Town, South Africa

 Sharks

have been dominating the ocean for the past 400 million years, and have received a well-respected name for being the ocean’s fiercest specie, and hunter. Humans fear them, we respect them but no matter what we are still fascinating by this fearsome predator.

 South Africa, but more specifically Cape Town is one of the best locations probably in the world to see and experience sharks, especially the Great White Shark in close proximity.  The population of sharks in Cape Town is unmatched anywhere else, the shark diving locations are easily accessible and very close to land; making it easy for humans to see these creatures at what they were best trained to do.

 Shark Cage Diving in Cape Town – truly an adventure

Cage diving with sharks and surface viewing has become an ever increasing popular activity in the tourism industry. People travel the globe just to witness these incredible species, and to meet them eye-to-eye. And what a remarkable experience isn’t it to get in the water along with the ocean’s greatest predator? People apprehend this adrenalin filled adventure with great anticipation and excitement and return with the greatest passion and respect for these fascinating creatures.

 Shark cage diving is a strictly regulated industry and there are only a few operators that have been good enough to be awarded a license to take people out to the ocean to view the sharks. Great care and effort are taken not to interfere with the shark’s natural behaviour patterns. The feeding of sharks are also prohibited so the sharks don’t misinterpret the boat as its delicious next meal. Passengers on the boat are most likely to see the Great White Shark as other sharks tend to keep a low profile in their territory. The Cape Coast is one of the most popular locations, in the world, to find Great White Sharks, and a lot of them.

 The Shark Cage Diving Adventure begins

When the passengers board the boat ready to take off for their trip out on to the ocean, the air is filled with great excitement and overwhelming emotions. Usually it takes about an hour of chumming before the first shark arrives; once the sharks have calmed down the first group of people get ready to enter the cage and be lowered down into the water. The other passengers then retreat to the back of the boat or the viewing platform to view the spectacular that will shortly follow.

 Once the cage is in the water the bait line is drawn to the cage and lures the Great White Sharks to the cage. It is at this moment that you feel like your heart has stopped beating and some people feel something warm between their legs. Needless to say, the cagers’ emotions are running high.

 But it is not just the cage divers that are experiencing this remarkable moment, but the passengers view point from the boat is also excellent as they can see the sharks’ every movement. As they approach the cage, circle it and descend again. The surface viewers are also in the ideal position to capture this moment by camera.

Shark Cage Diving Locations

There are two great areas down the Cape Coast which is excellent for Great White Shark Cage Diving: Gans Bay and Mosselbay; both are easy accessible from Cape Town International Airport. The best time to shark cage dive down the Cape Coast is between April and November mainly because of the mass-pupping of seals.

SHARK FEEDING TECHNIQUES


Bookmark and Share



READ THIS DISCLAIMER: Feeding sharks is an inherently dangerous activity which should not be undertaken without sufficient professional training. Even after such training it is possible to be seriously injured or die as a result of shark feeding activities. The information contained within Elasmodiver is not intended as a replacement for training by a qualified agency and is presented merely as an introduction to the styles of shark feeds that take place and the ethics and politics surrounding the sport.

 

Shark feeding techniques vary from operation to operation. Often the style of the feed is dictated by the species of sharks in attendance. Other factors include the experience level of the feeder and whether it is an organized feed for the public or an impromptu feed to obtain specific footage or information.

 

Chumming for Sharks instead of Shark Feeding

There is no doubt that feeding sharks changes their behavior. Repeatedly feeding sharks can cause them to become expectant of a handout whenever humans are around. This sometimes leads to sharks harassing divers that have no food and no desire to interact with them. Perhaps some sharks lose their ability to hunt naturally but it is unlikely that such highly evolved predators would become this conditioned unless they were fed consistently and in sufficient quantities that they never needed to hunt on their own. Even well fed sharks held in captivity occasionally go on hunting sprees, picking off their smaller tank mates between feeds.

The fact remains that if we are able to attract sharks without feeding them then the sharks are far less likely to become conditioned. The best way to do this is to pour some kind of chum into the water that will attract the sharks without actually satisfying their appetites.

Chum (or burley) may consist of all manner of food stuffs but generally the main ingredient is fish blood and/or ground up fish scraps. It is slowly ladled (or allowed to drip) into the water spreading the flavor of dying of dead fish far and wide. This excites the sharks and causes them to follow the scent towards the boat but once there they find no reward and after a few exploratory passes they continue on their journey.

 

Lowering Bait Crates

Another way to attract sharks without filling their stomachs is to lower milk crates or other sturdy containers into the water that are filled with fish parts. The bobbing action of the boat tends to stir up the scraps allowing very small quantities to escape downstream. One advantage of using this method is that the sharks have a specific target on which to concentrate their attention (compared to the chum slick created by the ladling method). This means that photographers or divers can either avoid the crates and swim outside the sharks field of interest or alternatively hold onto the ropes suspending the crates (especially handy in a strong current) so that they are well positioned to get the shot. Of course the closer they choose to put themselves to the crates the more dangerous their predicament becomes.

 

Shark Wrangling

This method of bringing sharks towards the boat involves tossing out fish with a line tied through the gills or eye sockets. This will result in attendant sharks chasing the fish directly towards the boat until the fish is pulled out of the water at the last minute. It may seem like a way of teasing the sharks but in their natural environment they would also not always manage to strike the prey that they go after.

Although wrangling limits the amount of food that the sharks receive, they invariably manage to take the bait sooner or later so this is definitely a form of shark feeding.

Photographers have two ways to take advantage of shark wrangling. They can get quite interesting surface shots from the deck of the boat or they can use a pole cam (a camera suspended just below the water) to get very close feeding shots. The benefit being that there is little danger for the photographer. A rather more precarious way to utilize shark wrangling is to hang from the swim step where the bait will pass by on its way out of the water. This is not the smartest place to be considering how fast the shark is likely to traveling in its pursuit of the bait.

 

The Chumsicle Feed

Pioneered by Walkers Key in the Bahamas, the chumsicle consists of a giant popsicle made of frozen fish scraps. This is lowered into the water once the divers have settled onto the seabed out of harms way. The sharks then attack the block of food as they would a bait ball or large floating carcass. The action around the chumsicle can be quite intense especially if many reef sharks are in attendance. They will compete fiercely for the food and rip away chunks as fast as possible before it is completely consumed by their fellow sharks.

Generally the divers are completely ignored and once the sharks have devoured the food they disperse or hang around on the periphery. Comically the divers often then rush in to perform their own ‘feeding frenzy’ competing for sharks teeth that usually get dislodged during the feed.

Although the chumsicle shark feed can present a good spectacle for divers and photographers, visibility often becomes poor once the frenzy heats up and lots of scraps are floating around. Also snappers and other local fish that are used to the feeds will congregate in such numbers that a clear shot of the sharks often becomes impossible.

 

Pole Feeding and Hand Feeding Sharks

There are endless ways to hand feed sharks. Most feeders wear some form of chain mail to avoid bites. This can range from simple gauntlets, to full sleeves, to complete chain mail or even Kevlar suits. I have seen divers hand feeding sharks without gloves and I have even been to official shark feeds where the gloveless feeder is only expecting nurse sharks to show up but wearing some kind of protection is generally accepted.

Some feeders prefer to attach the fish scraps onto the end of a pole to add some distance between themselves and the sharks. This is obviously a prudent thing to do but it means that the shark has to chomp down on a steal rod to get the food. This isn’t ideal for the shark or for the photographer looking for a more natural looking feeding shot. Experienced feeders will sometimes hold the bait between their gloved fingers and lead the shark forward (right over the photographers lens) letting go at the last minute and withdrawing their arm from the photographers field of view. This can result in some extremely dramatic images.

In organized hand feeding dives the spectators are prepped beforehand on correct etiquette. Generally they are asked to kneel in a line or large semi circle around the feeder. This can result in some thrilling close passes as the sharks converge on the feeder.

 

Freestyle Shark Feeds

Get a bunch of shark crazy photographers aboard a boat, give them a bucket of fish, and wait to see what happens. On some dive boats where experienced divers are looking for close encounters there may be lots of different shark encounters going on at once. Looking around on one recent dive in the Bahamas I could see two photographers patiently waiting on the sand next to some fallen bait while a third photographer was manically waving a fish around. Turning back to the boat I spotted a diver literally sitting on a suspended bait crate and to top it off their was a videographer hanging onto the swim step while a topside diver pulled  a roped fish over his head. Six or seven Lemon Sharks were busy vacuuming up whatever was offered while a Tiger Shark nervously skirted the edges of the party mostly out of sight. Nobody died. In fact, looking at each diver individually no one was really even in that much danger other than the ‘human polecam’ up on the swim step.

 

Spear Fishing while Feeding Sharks.

Probably the most dangerous addition to any feed is a spear gun. The struggling vibrations emanating from dying or wounded fish on the end of a spear will cause any sharks present to become a lot more agitated. And, agitated sharks are unpredictable. Also, think about the impact that spearing fish has on the environment. Commercial fishermen are going to kill fish regardless of whether the leftovers will be used to supply a shark feed so whenever possible try to use the bi products of normal fishing activities rather than adding to the carnage

A great white survives an encounter with a caged Tarquin Cooper

Shark Diving South Africa | Shark Cage Diving

http://www.downhilladventures.com

Sometimes only a four lettered word will do, and this is one of them. I mutter it silently to myself as nature’s number one predator appears from the abyss. More expletives follow, slowly at first and then rapid fire as the full might of the ocean’s greatest hunter turns and heads straight towards me. Closer and closer, with a mouth opening and closing as if in anticipation, it is Carcharodon Carcharias otherwise known as the great white shark.

Tarquin Cooper takes a picture of himself with a great white shark 
The only thing separating me from those infamous teeth, now only 12 inches away from my face, is the mesh of a stainless steel cage, and I can’t help noticing that some of the bars are bent. How did they get that way? Are they strong enough to withhold this cartilaginous hulk’s curiosity? If you could see my eyes they would be out on stalks, my eyebrows on full extension by the sight transfixing me. But it is awe induced not by terror, but by wonder.

“People expect to find a mindless eating machine that attacks everything and everyone,” says Morné Hardenberg, our shark diving guide. “But they go away with a different perception.”

The great white is an incredible creature. Over 400 million years it has evolved into the ocean’s largest predator, a torpedo shaped hunting machine equipped with sensors that can pick up the electro-magnetic pulses every living thing beneath the sea produces. Its colouring is ideal for the hunter. It’s surely no accident that it has been copied by military aircraft; the light underbelly to blend with the surface, the darker steel blue top side that makes it hard to spot from above, and broken lines of contrast to complete the camouflage.

What could be more exciting than coming face to face with it? Never mind that you’re more likely to die from falling down the stairs than from a shark, it’s the imagined fear that’s exciting. Just hum the theme from Jaws and imagine that dead eye stalking you in cold dark waters.

Since it started about ten years ago cage diving has become more and more popular. Those to have enjoyed the experience include Prince Harry on his recent tour of Africa, who saw a shark maul a seal, and Brad Pitt.

But not everyone is enthusiastic. Many locals accuse diving operators of encouraging sharks to enter waters where humans swim by the practice of ‘chumming’ – where fish is thrown to attract them.

A great white comes a bit too close for comfort 
Although attacks are rare, about four a year for the whole of South Africa, they do happen. A few weeks before my arrival a British surfer nearly lost his leg to a shark in Cape Town and last year an elderly swimmer lost her life to a shark in the same bay. But diving operators say chumming only attracts sharks that are already in the area.

“Chumming has got nothing to do with it,” says Michael Rutzen, owner of Shark Diving Unlimited. “We chum with animals that occur naturally. Chum where there are no sharks and you don’t get any.” It’s a view supported by shark environmentalists.

Rutzen adds that shark diving has a vital role to play in re-educating the public and protecting the great white. “We have to show people these animals to ensure their survival. It’s no different from viewing leopards and lions.”

Cage diving occurs off Gansbaai, about 120 miles east of Cape Town, South Africa.

We set off in a 42ft double decked boat to ‘shark alley’ a narrow channel between two islands about a mile offshore, one of which is home to a colony of 50,000 seals. It’s a feeding ground for hundreds of migrating great whites, some of whom end up in Australian waters.

After dropping anchor the process of ‘chumming’ begins. Parts of tuna, soup fin shark and other fish are tossed overboard.

Suddenly the excitement on board is palpable – the first shark has been spotted and it’s circling the boat. The cage is lowered and tied on securely at four points. I step into it and the waterline reaches my neck. It is large enough for five of us. The water is cold. As the skipper and crew spot sharks approaching they shout the command, “Down. Down. Down.” We hold our breaths and go under. The cage doesn’t move – it remains wedded to the boat.

My first thought on seeing a great white is how graceful and powerful it is. One swims past our cage and I and the others can’t resist touching its rubbery skin. We surface to a strict telling off. “No touching,” shouts skipper Frank Rutzen. “They are not puppy dogs.”

I don’t need any reminding with the second shark. It heads right for me, bashes the cage and starts chomping on the bars, just inches away.

Scared? Too right I am – I can’t hug the back of the cage hard enough. But it’s exhilarating and I surface to cheers from the boat.
