Experts at the Florida Fish and Wildlife Conservation Commission now say it is red tide that is killing fish in Grand Lagoon on the east end of Panama City Beach.
Neighbors say the fish washed up on the Safari public dock on South Lagoon Drive sometime overnight Monday.
People who live in the area were worried it might be red tide, and they were right. Although several agencies earlier Tuesday said water samples had shown it wasn't, but that all changed late Tuesday when biologist said it was red tide.
Lagoon area resident Kurt Brand says it’s pretty bad in the lagoon right now.
“We've been here for 25 years and when I walked out this morning this is about the worst we've seen. The lagoon was literally full of dead fish."
If you find any fish washed ashore, you're asked to call the Florida Fish and Wildlife Conservation Commission at 1-800-636-0511.
