Harmful algae in the Strait of Georgia, 2015-2023

Pacific Salmon Foundation (PSF) dataset on marine microalgae (20-200 µm) that are known or suspected to have a negative effect on aquaculture (finfish, shellfish) based on ~bi-monthly sampling (up to 20 times a year) from ~55 sampling sites in the Strait of Georgia, Canada. Samples were analyzed on a Sedgewick-Rafter slide; the identification of specimens was done to the lowest taxonomic level possible and the enumeration (as cells mL-1) by a taxonomist certified by Intergovernmental Oceanographic Commission (IOC) in Proficiency in Identification of Harmful Algae.
