Usage notes
Fritz et al., (1992: 439, J. Phycol.: 28) notes this species is a likely source of domoic acid (DA), the amnesic shellfish poisoning toxin, a bloom of which occured in Monterey Bay, California, September 1991. Harmful species (Lassus et al. 2017). - (11 May 2006) - G.M. Guiry
Much research has determined that eutrophication highly affects the bloom dynamics of Pseudo-nitzschia australis off the Californian coast. Run-off from streams and rivers has high concentrations of both nitrates and phosphates, which triggers blooms offshore. However, much research and testing in the lab indicates that metal concentrations such as iron and copper can significantly influence domoic acid production within the diatoms (Watershed Resource Center, UCSB) - (28 March 2009) - M.D. Guiry
