Firstly, the cage diving industry does not feed the Great Whites. The chum (which is a wholly natural combination of fish oil and other fish byproducts) lures them to the boat, and the Tuna head is used to keep the sharks visually engaged. Occasionally, they will bite onto the bait before the bait handler has a chance to pull it away. If they want the Tuna head, they will have to work for it, so there is no outright feeding of the sharks.
Dyer Island, where the sharks spend the bulk of the year off our coast, is home to approximately 60 000 Cape Fur seals. The Great Whites have been coming here for years due to the abundance of natural prey; fish oil and Tuna heads won't make any difference. To quote a colleague, its like a drop in the ocean.
Thomas Peschak, a noted Great White photographer and book author, has scientifically dispelled the above myths through his book 'Great White Shark'. His work has been recognised by National Geographic and BBC Wildlife.
Please don't let ignorance of our industry prevent you from visiting our charming part of the South African coast and partake in one of the worlds greatest experiences.
