拟菱形藻属的物种与北美沿海软骨藻酸（DA）毒性的爆发有关。这使我们看看历史（1930年至1939年，1967年，1983年，1991年至1993年）的发生和丰富的这些物种的斯克里普斯海洋研究所码头，南加州，美国，特别强调l？我们有最完整的数据。该生物体在2月至8月期间以高数量（10'至106个细胞I-'）零星出现，但没有重大毒性事件的报道。高丰度的时期与入侵的凉爽，高营养沃茨可能与上升流事件。到目前为止，在南加州湾还没有大的DA疫情。
Species of the genus Pseudonitzschia have been implicated in outbreaks of domoic acid (DA) toxicity off the coasts of North America. This led us to look at the historical (1930-1939, 1967, 1983, 1991-1993) occurrence and abundance of these species off the Scripps Institution of Oceanography pier, Southern California, USA, with special emphasis on l? australis Frenguelli for which we have the most complete data. The organism occurs sporadically in high numbers (10' to 106 cells I-') between February and August but no major toxic episodes have been reported. The periods of high abundance were associated with intrusion of cool, high-nutrient waters probably related to upwelling events. To date, there have been no major DA outbreaks in the Southern California Bight.
