The proportion and content of free fatty acids (FFA) in four species of causative phytoplankton of red tides, cultured in axenic conditions, were obtained by fluorometric high‐performance liquid chromatography. Twelve FFA in phytoplankton were identified. Raphidophyte flagellates, Chattonella antiqua and Heterosigma akashiwo , contained highly unsaturated fatty acids and 16:0 acid as the predominant FFA. Major FFA in diatoms, Skeletonema costatum and Chaetoceros didymum , were 14:0, 16:0, 16:1, and 20:5 acids.
