Authorities are investigating a bunch of fishy deaths in Los Angeles this morning.

Thousands of dead fish rose to the surface of the water last night in Marina Del Rey near Ballona Creek, and it's not clear why.

California Fish and Game officials are on hand trying to clean up the fish die-off before the smell becomes unbearable for nearby residents.

A sheriff's deputy helpfully told City News Service that the die-off "probably had something to with the eco-system." NBC reports that "lack of oxygen" may have been the problem.
