On the basis of hydrological and biological data collected between 1983 and 1987 along the French coast, and especially in the southern approaches to Brittany. it has been possible to compare different parameters in an attempt to explain the seasonal variations of a toxic dinoflagellate: Dinophysis sp. speveral species were identified and their seasonal distribution patterns are described. The origin of the blooms, from either coastal endemic or offshore populations, is considered
Résumé
À partir de données hydrologiques et biologiques obtenues entre 1983 et 1987 sur les côtes françaises, et en particulier en Bretagne Sud, il a été possible de comparer différents paramètres pour tenter d'expliquer les variations saisonnières d'un dinoflagellé toxique : Dinophysis sp. Plusieurs espèces ont été identifiées et les modalités de leur distribution sont décrites. Le problème de l'origine de ces efflorescences : populations côtières endémiques ou venant du large, est considéré.
