| Management decision: | Harvesting was closed in culture areas when .PSP toxins concentrations was over 80 µg STX eq /100 g wet weight. | |||||||||||||||||||||||||||||||
| Additional harmful effect information: | Irrelevant effects, because the closures caused by this event were brief (two weeks maximum). Closures due to the presence of toxicity in molluscs is usual in the area and resource exploitation strategies allows to face these closures without great prob | |||||||||||||||||||||||||||||||
