Winter distributions of Dinophysis populations: do they help to predict the onset of the bloom?

Blooms of diarrhetic shellfish toxin (DST) producers of the genus Dinophysis (D. acuminata, D. acuta) pose the main threat to the sustainable exploitation of cultivated mussels and other bivalves on the Atlantic coasts of Europe. Dinophysis species do not rely on cysts as a seeding strategy. Detecti...
