KBNERR warns of potential harmful algal bloom in Kachemak Bay
Homer, Kenai Peninsula Borough, Alaska, United States
Jul 4, 2025
The Kachemak Bay National Estuarine Research Reserve detected Pseudo-nitzschia at bloom levels in Kachemak Bay starting July 4. 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.
