Shark attacks could be tied to migration

Are shark attacks tied to migration?

HONOLULU (AP) — Scientists are seeing growing evidence that eight shark attacks in Hawaii may be connected to the seasonal migration patterns of tiger sharks.

The University of Hawaii study involves about 10 years of information and tracking more than 100 tiger sharks with sonar and satellite monitoring devices.

University of Hawaii assistant researcher Carl. G. Meyer said a preliminary study indicates the tiger sharks migrate in deep water as well as in shallow areas where people swim and surf.

Tiger sharks migrate from the Northwestern Hawaiian Islands to the main Hawaiian Islands in October and November to give birth. The Hawaii Institute of Marine Biology says they are the most wide-ranging predator in the Northwestern Hawaiian Islands, routinely swimming hundreds of miles.

State officials have said most shark attacks occur during September, October and November.

Three of the recent attacks on Maui are thought to have been from tiger sharks.
