KBNERR warns of potential harmful algal bloom in Kachemak Bay

Homer, Kenai Peninsula Borough, Alaska, United States

This diatom can produce the toxin domoic acid, associated with amnesic shellfish poisoning, though toxin production is not yet confirmed. Observed bird deaths and marine mammal strandings have spurred collection of mussel samples for lab testing.
