| Management decision: | Harveting was closed in culture areas when domoic acid concentrations was greater than ppm. | ||||||||||||||||
| Additional harmful effect information: | Irrelevant effects, because the closures caused by this event were brief (two weeks maximum). Closures due to the rpesence of toxicity in molluscs is usual in the area and resource expolitation strategies alow to face these closrues without great problems | ||||||||||||||||
