    Researchers say migration patterns of the tiger shark from the Northwestern Islands of Hawaii to the Main Hawaiian Islands could be the cause of the recent increase in shark bites.

    Researchers say the large numbers of shark attacks off the coast of Hawaii may be explained by migratory patterns.  A 7-year study of the tiger sharkmovement from biologists at the University of Hawaii and Florida found thatabout 25% of mature female tiger sharks that normally stick close to the Northwestern Hawaiian Islands travel to the Main Hawaiian Islands in the last summer andfall, primarily to give birth.  This migration coincides with increased reports of shark attacks.  Already this year there have been 8 reported attacks and the first fatal attack since 2004.
