| Abstract: | Pseudo-nitzschia spp. Are extremely abundant on the Louisiana shelf in the extended plume of the Mississippi River. At least 6 species have been observed in this region, and there may be more unknown species. Five of the species observed in Louisiana waters have been shown to produce domoic acid (DA) in field samples or laboratory cultures. This brief report summarizes evidence that Pseudo-nitzschia spp. are stimulated by high nutrient inputs, thereby increasing the potential for DA poisoning incidents in areas where eutrophication is increasing. |
