A resurgence of red tide at the Gulf Coast is worrying some fishermen but is not an immediate threat to the public, officials said. A ban on harvesting shellfish went into effect after the organism was found in Corpus Christi Bay. The red tide extends across Corpus Christi Bay through Redfish Bay and into the Lydia Ann Channel between Port Aransas to Aransas Bay, state health department reports said. An infestation in the fall killed an estimated 22.2 million fish. The toxin given off by red tide is not fatal to humans, although it can irritate the eyes, throat and respiratory system.
