Authorities are working to clean up millions of dead fish that washed up in King Harbor near Redondo Beach on Monday.

Thousands of fish were cleaned up with skimmers and bulldozers on Monday, but much more work remains to be done.

The dead fish, mostly sardines along with anchovies and mackerel, floated up to the surface from the ocean floor.

Officials said there is layer of fish about 12 to 18 inches thick covering the bottom of the marina, and those fish will wash up to the surface in the days ahead.

12 to 18 inches!!! That's a lot of dead fish!

Some pretend it's a sign for upcoming earthquakes. Who knows...

That toxin (the Domoic acid) would be produced by a specific phytoplankton gene.
In 1958, domoic acid was originally isolated from the red alga called "doumoi" or "hanayanagi" (Chondria armata[2]) in Japan. [...] Domoic acid can bioaccumulate in marine organisms such as shellfish, anchovies, and sardines that feed on the phytoplankton known to produce this toxin. Domoic acid can accumulate in high concentrations in the tissues of these plankton feeders when the toxic phytoplankton itself is high in concentration in the surrounding waters.

They also say that the high concentrations of these toxin-producing-phytoplankton would be because of the algal bloom, mostly around the populated coastlines. It could be an answer why these fish all died.
