Domoic acid (Fig. 28,80) (263) is a neuro-phycotoxin responsible for the mortality of wildlife and for amnesic shellfish poisoning (ASP) of humans during algal bloom. Domoic acid was first isolated from the red alga Chondria armata ( domoi in Japanese), and it is produced also by diatoms, such as Pseudo-nitzschia spp. For the latter, evidence has been presented that it is involved in iron acquisition (307).

The term amnesic shellfish poison (ASP) has been coined for this new shellfish toxin. The causative organism of ASP was then identified to be the pennate diatom Nitzschia pungens Grunow f. multiseries Hasle, a bloom of which contaminated the cultured mussels in eastern Prince Edward Island in 1987.
