A very similar incident also occurred off the coast of Guadalupe Island off the coast of Mexico. In this case the diver was luring the shark with tuna … well what happens next is caught on the video clip below.
What surprises me here is that the support team didn't know if there was anyone in the cage … humm. You can read more details about this incident here on the dailymail.co.uk
Further insights into these occurrences, as highlighted in a posted on earthtouchnews.com, highlights the use of improper and often illegal chumming / baiting practices.
Some have suggested that because chum bags simply hold bait, operators who use them are not explicitly “feeding” white sharks – and this is exactly the kind of loophole that makes enforcing the rules such a challenge. This argument certainly doesn't hold up against the 51-page Guadalupe shark-diving code of conduct, which was put in place by the National Commission of Natural Protected Areas (CONANP), one of the area's ecotourism governing bodies.
Its rules clearly stipulate that bait lines must not touch the cage (or pass over the top). They also require operators to immediately remove the line from the water upon a shark's close approach, and prohibit the use of bait on a line shorter than 40 feet (12m). In recent years, many dive outfits have been opting to bring CONANP reps along on their charters in order to prevent serious mishaps like this one.
