Toxic Bloom Olga Strait

“In June, the straits, bays and islands of Puget Sound experienced some of the most extensive harmful algal blooms (HABs) in recent memory, including at least five potential toxin producers. Blooms of Heterosigma akashiwo, which causes massive fish kills, were widespread and threatened the salmon net pen mariculture industry.Enhanced HAB monitoring in the area led to an advanced warning of the bloom, which helped salmon farmers reduce fish mortalities.”
