Correction: Dolphin Deaths story

NAPLES, Fla. (AP) — NAPLES, Fla. (AP) — In a story Nov. 27 story about a red tide being suspected in dolphin deaths, The Associated Press erroneously cited the National Oceanic and Atmospheric Administration as saying red tide happens when algae colonies grow out of control due to pollution from farming and other human activities. NOAA says environmental conditions such as light, temperature, nutrients and ocean currents are factors that can lead to the uncontrolled algae growth.

Officials: Red tide suspected as dead dolphins wash ashore

NAPLES, Fla. (AP) — Officials in Florida say dolphins seem to be red tide's latest victims as more than 20 have washed up dead since last week along the state's southwest coast.

News outlets report 22 dead dolphins appeared on beaches since Wednesday. In Naples, Harbor Master Roger Jacobsen says three dead dolphins washed ashore since Sunday. Seven counties have seen higher than normal numbers of dead dolphins on beaches since July.

National Oceanic and Atmospheric Administration marine mammal stranding coordinator Blair Mase says tests need to be completed but it seems brevetoxin is killing marine life, and higher red tide counts are expected this week.

NOAA says red tide can occur when environmental conditions such as light, temperature, nutrients and ocean currents allow algae to grow out of control and produce toxins with harmful effects on people, fish, marine mammals and birds.
