Abstract
Between 1994 and 1999 the relationship between Dinophysis species and diarrhetic shellfish toxins (DST) in blue mussel (Mytilus edulis) was studied in Flødevigen Bay on the south coast of Norway. The concentrations of Chl a, Dinophysis acuminata, D. acuta and D. norvegica were quantified every Monday, Wednesday and Friday, and approximately fortnightly DST occurrences in blue mussel (M. edulis) were analysed by mouse bioassay. In addition, we report a separate study of DST in blue mussel and Dinophysis spp., based on HPLC analysis. The highest concentrations of DST in blue mussel were observed during the low productivity period from November to February. Shortly after the onset of the spring phytoplankton bloom, DST in blue mussel dropped to zero and remained low until September. There was no relationship between DST in blue mussel and the concentrations of D. acuminafa and D. norvegica. Dinophysis acuta was probably the main source of DST in blue mussel. There was, however, no clear relationship...This publication has 1 reference indexed in Scilit:
