Title

Factors affecting the concentration of domoic acid in shellfish.

Objectives

Amnesic shellfish poisoning (ASP) has proved problematic for king scallop fisheries in Ireland necessitating restrictions on the sale of fresh scallops (in-shell), which achieve a higher market price than the frozen processed product. ASP is caused by the consumption of shellfish contaminated with the toxin domoic acid, produced by Pseudonitzschia species. This project is investigating temporal and spatial variations in the concentration of the toxin, domoic acid, with both the size of the scallop and with the water depth from which the scallops are fished.
