This week Pseudo-nitzschia continues to dominate samples throughout Kachemak Bay. Pseudo-nitzschia is at bloom levels in Halibut Cove, Peterson Bay, and Jakolof Bay. Similarly Pseudo-nitzschia dominated samples during July in 2014 & 2017. As a reminder Pseudo-nitzschia can produce domoic acid which can lead to amnesic shellfish poisoning when toxic shellfish are consumed. Domoic acid also impacts seabirds, fishes and marine mammals, causing lethargy, disorientation, seizures and even death. Please let us know if you observe animals in unusual places or exhibiting unusual behavior. As always we recommend leaving these animals alone. Stranded marine mammals can be reported to the Marine Mammal stranding network by calling 1-888-774-7325.
