| Laboratory bioassays have been performed. using toxic P. tamarensis mass cultures (MOG 835), in order to assess potential depuration kinetics of PSP contamined cultured blue mussels. Besides, from fields observations and translocation experiences to safe area, we have seeked for probable depuration kinetics of shellfishes having accumulated during summer 1986 high levels of DSP producing Dinophysis. Such preliminary studies may drive to further experiences giving more accuracy to the establishment of thresholds recquired by shellfishes depuration policy. |
