Toxin found in dead sardines http://apocadocs.com/s.pl?1299944218
Sardines that suffocated and died en masse this week in King Harbor have tested positive for a powerful neurotoxin that scientists believe may have distressed 1 million or more fish off the Los Angeles coastline and caused them to swim chaotically into the Redondo Beach marina.
Researchers still believe critically low oxygen levels, not the toxin or an algae bloom, caused the fish to suddenly die Monday night in the Redondo Beach marina.
But the discovery of domoic acid in dead fish -- reported Friday by USC biologists -- could help explain why millions of sardines swam into the harbor in the first place... Domoic acid is often found in the stomachs of fish that have been feeding on plankton on the ocean's surface during toxic algae blooms. The toxin has been linked to neurological disorders, illnesses and deaths of seabirds, sea lions, sea otters and whales. When it accumulates in edible fish and shellfish, it can sicken humans.
