Abstract Sixteen species of unialgal samples of dinoflagellate, either wild or cultured, were tested for production of diarrhetic shellfish toxins such as okadaic acid (OA), dinophysistoxin-1 (DTX1), and pectenotoxins (PTXs). Determination of micro-quantities of the toxins was facilitated by fluorometry and UV HPLC. Seven Dinophysis species were confirmed to produce either OA or DTX1, or both. Toxin content and composition varied regionally and seasonally. Intraspecies variation was also observed among cultured strains of Prorocentrum lima. PTX2 was the only toxin detected among PTX family, and D. fortii was the only species to contain this toxin.
