Detection of domoic acid in Mytilus galloprovincialis and Ostrea edulis linked to the presence of Nitzschia bizertensis in Bizerte Lagoon (SW Mediterranean)

Our results indicate for the first time a Nitzschia species, here Nitzschia bizertensis, could be in relation to accumulation of DA in shellfish. Monitoring of DA in phytoplankton and shellfish should be considered for Bizerte Lagoon in order to gain knowledge about the ecology and toxin-production of N. bizertensis and to explore the risk of DA accumulation in the local shellfish industry caused by this species.
