Presentation Abstract
Heterosigma akashiwo is the most significant fish-killing algae species in British Columbia, and the Salish Sea historically has the most intense and prolonged H. akashiwo blooms in BC. There is strong interannual variation of H. akashiwo blooms in the Salish Sea that has been linked to decreased salinity from the Fraser River plume. Here we present data from weekly phytoplankton and environmental monitoring at Departure Bay by the Harmful Algae Monitoring Program (HAMP) from 2001 to 2017. Concentrations of H. akashiwo in Departure Bay are compared with Fraser River discharge, salinity, and temperature. Densest H. akashiwo blooms typically appear in mid-late June, with lesser blooms in July and late-August to mid-September in some years.
