Since May 2023, several Harmful Algal Blooms (HABs) have been detected in Alaska. HABs can be detected through the identification of harmful algae (primarily phytoplankton in the genus <\/span>Alexandrium<\/span><\/i> or <\/span>Pseudo-nitzschia<\/span><\/i>) or by the testing of food items such as shellfish for algal toxins, such as paralytic shellfish toxins (PSTs).<\/span><\/p>\n

Elevated levels of PSTs were found primarily in two regions of Alaska. In June and early July, the <\/span>Knik Tribe<\/span><\/a> found high levels of PSTs in shellfish collected in Sand Point, King Cove, and Chignik Lagoon. Primarily in Juneau, the <\/span>South East Alaska Tribal Ocean Research (SEATOR)<\/span><\/a> consortium found high levels of PSTs in shellfish throughout July.<\/span><\/p>\n

Alexandrium<\/span><\/i> blooms were detected in the Chukchi and Bering Seas in late July by researchers at Woods Hole Oceanographic Institution. There was also a visible bloom of <\/span>Mesodinium<\/span><\/i> phytoplankton in Tutka Bay in June (see picture). Despite the discoloration of the water, the Tutka Bay algal bloom was not considered harmful and dissipated rapidly.<\/span><\/p>\n

Please visit the Alaska Harmful Algal Bloom Network<\/a> for more information.<\/p>\n
