Millions of dead fish, including anchovies, sardines, and mackerel, started washing up at King Harbor Marina in Redondo Beach, CA last night. Authorities say that that dead fish are about a foot deep on the surface of the water, and are investigating possible causes of the massive fish deaths.

“There’s basically fish everywhere you go in the harbor,” the harbor’s assistant manager, Jason McMullin, told the Los Angeles Times.

“We’re having millions of anchovies die off in our harbor,” Redondo Beach police Sergeant Phil Keenan told Reuters. “At this point it’s an unknown reason.”

Initial theories to the deaths include red tide, and too many fish congregating into a small area thereby depleting the water’s oxygen supply. Either way the fish have been attracting swarms of seagulls and other birds into the area, requiring cleanup of their bodies to be a main priority.

“The issue now is cleanup because we have tons and tons of dead fish rotting and purifying, which obviously creates hazardous material,” Keenan said. “We’re in the process of figuring out what were going to do.”
