A persistent and unusual bloom of Dinophysic acuta Ehrenberg in the RIas Bajas (Northwest Spain) from early July to mid-November 1989, was associated with a diarshetic shellfish poisoning (DSP) outbreak that prevented mussel extraction in some areas from early August to mid-December. Dinophysis reniformis Schröder 1906. Integrated samples (0–5, 5–10 and 10–15 m) were taken once or twice a week at six stations.

Fig. Dinophysis acuta Ehrenberg, 1839 Species Overview: Dinophysis acuta is an armoured, marine, planktonic dinoflagellate species. Dinophysis ist eine Gattung von Dinoflagellaten, die in tropischen, gemäßigten, Küsten- und Ozeangewässern verbreitet ist. There are five types of thecae ornamentation in this genus, and those are a useful character for species identification. In the Ría de Aveiro (40°41'N), the species reached a maximum concentration of 5.0 × 10 4 cells l −1 on 8 September, the highest value in a 17-year record of monitoring. SEM: lateral view. It is one of the few unusual photosynthetic protists that acquire plastids from algae by endosymbiosis. They are often followed by short-lived blooms of Dinophysis acuta, associated with northward longshore transport, at the end of the upwelling season. 1868.
