Abstract: | Growth of dinoflagellates representing three orders, the Gymnodiniales,Peridiniales, and the Prorocentrales was examined following treatment withbarley straw extract. Selected dinoflagellate taxa showed growth responsessimilar to those reported for freshwater algae including: inhibition(Gyrodinium galatheanum, Gymnodiniumsanguineum, Heterocapsa triquetra andH. pygmaea); stimulation (Gyrodinium instriatum,Prorocentrum minimum and P. micans); and no effect(Gyrodinium estuariale, G. uncatenum,Ceratium furca, Peridinium sp.).Although barley straw extracts do not appear to have value as a universalmanagement tool for dinoflagellates, they may have potential in management ofspecific taxa and possibly taxonomic groups. |
