Jaws comes to Stewart Island

Two Dunedin men are ready to dip caged tourists into Foveaux Strait to allow them get up close and personal with the predator at the top of the ocean's food chain - the great white shark.

Great White Southern Dive co-owner Pete Dryden said he had been down in the cage three times and had seen great white sharks each time.

Five of the massive fish swam around the 2m-high aluminium cage on his first dive, much to his amazement.

The experience of seeing sharks "with heads the size of the end of a 44-gallon-drum" close up was incredible, the former paua diver said.

"It's pretty awesome. It's something you can't describe. They're amazing."

Co-owner Peter Scott said since completion of the cage in January, it had been used by a Department of Conservation marine ecologist to tag great white sharks in the Southern Ocean.

It had also been used by NHNZ for 10 days to film a documentary on great whites.

Mr Scott said the $4500 cage had been tested extensively to make sure it would keep out the sharks.

He was now ready to take public ecotours in Foveaux Strait.

Cages used in South Africa and South America had taken a hammering from aggressive great whites, but Mr Scott said those living in southern waters were comparatively placid and inquisitive.

"I think it's because they are not hungry. There's plenty of food for them to eat around Stewart Island.

"Cages dropped in South Africa and South Australia have had their air hoses chomped through by the sharks. But our cage is indestructible because it sits just below the surface by the boat."

Sharks are lured near the cage by fish oil thrown into the water.

Mr Scott said when he first began the project, it was difficult to know whether it would work.

The biggest issue was what fish tourists would see, and how many tourists would want to see it, he said.

"The dives so far have produced pretty good results. They have exceeded our expectations."

Depending on the tours' popularity, members of the public could charter a dive in the cage for about $500 per person, per day, Mr Scott said.

The cage would hold up to four people at once: three tourists and one safety diver.

"Being up close and personal is a thrill. It's such a unique experience. You definitely wouldn't do it without a cage."

 

Great White Cage Diving

I would have to say that such an operation has many risks involved. The GW is well-known to leap clear out of the water and to raise its head out of the water to have a look at you! Air-hoses that "sits just below the surface by the boat.." is no problem for a GW to have a go at .. seeing the cages are some "2m high". So is the cage connecting cables!! South Africa has some examples where things can go wrong! Australia also has it's share of problems that can happen. To say that NZ GWs' are "placid" is nonsense. They are the masters of the sea, all over the world, and are totally unpredictable. Anyone knowledgeable about these creatures will know this. Being in the water with them (in a cage) also teaches you a lesson or two if things get nasty!! To say a cage is indestructible is nonsense when you are talking of a 2-3 tonne shark charging you full steam! STEALTH is their weapon and they use it effectively with deadly effect. I can see the 'chumming' may very well endanger others in the area as GWs' are known to roam 000s' kms so there's no guarantee that if you're paua diving close to these operations, or skin-diving, with neighbouring chumming enticement, that you're not going to be a target? There is no guarantee except for risk. Foveaux, Cook, & the Chathams all have very large GWs' and, some, much larger than our Auz & South African counterparts. It's fair to say there's plenty of food but you CANNOT say 'WHAT' food these GWs' would prefer? And, what attracts them (other than your standard Black wetsuit)!?
Foveaux presents some unpredictable weather as well so precautions need to be taken to help avoid the 'unexpected'. The paying customers need to be 'expertly-advised' as to the risks they are being subjected to. The GW is a great beautiful creature BUT one that MUST be given COMPLETE RESPECT as they are a creature capable of causing immense and unexpected suprises!! Who would wish to be on that suprise list?
We need to think very carefully about such operations! It may be good for tourism but dollars are no substitute for human life!!
We need to consider the livelihoods of the 'local' people? It is obviously true that they always dive knowing the GWs' are there but DO WE NEED TO TEMPT THEM with chumming? Like in the Chathams, the GWs' (and VERY BIG GWs'!!) are always there but DON'T tempt them!! The Gws' of the CHATHAMS are HUGE sharks as most kiwi fishermen will tell you. Don't fall in the water though!! GWs' need the greatest of respect as they are eating, swimming and breeding machines and that is all they do!!
That is all they they know!!
