Hundreds of dead fish are washing up on the shore in Volusia County.
Florida Fish and Wildlife Conservation Commission officials are trying to figure out what's happening.
Dozens of fish carcasses litter the Ormond Beach shoreline, which is causing a strong fish stench along the beach.
Wendy Leb walks the beach every morning with her friend. She didn't see the dead fish over the weekend, but she caught the smell before she saw where it was coming from.
"And today, I see a bunch of dead fish all along the shore, which I did not see yesterday," Leb said.
Volusia County Beach Safety and Ocean Rescue leaders are scratching their heads wondering where all of the fish carcasses came from.
Right now, the dead fish stretch from Standish Drive to Neptune Drive — about a 1-mile stretch.
"It could be any number of things," said Capt. Mike Berard, with Volusia Beach Safety and Ocean Rescue. "It could be something offshore, winds that it just brought in. It could be a boat that's dumped something. We haven't had any reported human effects related to this incident."
FWC spokeswoman Kelly Richmond said the commission doesn't believe this is the result of an algae bloom. It could be a result of trawling, Richmond said.
"Trawling is a method of fishing that involves pulling a fishing net through the water. Sometimes, smaller fish are a byproduct and they get stressed out and die," Richmond said in a statement.
