Climate change poses hazard to fish, marshes, e-xperts say

CHARLESTON -- In the summer of 2004, a married couple became ill from eating a toxin-polluted barracuda that had been caught off the South Carolina coast.

Never before had anyone caught a fish in South Carolina waters and gotten sick from ciguatera poisoning, a malady normally associated with species in Caribbean waters, according to the U.S. Centers for Disease Control and Prevention.
