Great whites wander widely, local tracking project confirms
GREAT white sharks may be visiting our shores, but they aren't hanging around, the State Government's tagging program has revealed.
The North Coast Local Waters Shark Tagging Project is tracking eight great whites tagged off the coast of Ballina and the State Government says results so far show the sharks are travelling widely.
"Data has shown the sharks are travelling large distances in a short period of time, with one tagged shark recorded to have travelled up to 550 kilometres in a week, confirming that white sharks are highly migratory along the NSW coast," a statement from Primary Industries Minister Niall Blair's office says.
Fairfax Media reports one of the sharks, a 2.2m female, was reported to have travelled 1000km in a month and, between them, the eight sharks had roamed close to 2300km.
Despite that, shark sightings remain a regular occurance on Northern Rivers beaches and Ballina Mayor David Wright has told Fairfax swimmers and surfers were being told to clear the water almost daily.
New measures aimed at protecting swimmers and surfers without harming sharks or other marine life are set to be discussed at a summit at Taronga Zoo tomorrow.
The government says the summit will involve more than 70 international experts, including several Australians, and representatives from Queensland and Western Australian, who will review a shortlist of technologies ranging from electro-magnetic shark deterrents to satellite tracking and warning technologies.
