| Abstract |
Morphological identification of dinoflagellate species were investigated from the coastal waters of Manora Island and Mubarak village Karachi, Pakistan throughout the two years of study period from (Apr 2008 - Mar 2010). A total number of seventy two dinoflagellate species were identified among them, 42 toxic and 30 HAB species were morphologically differentiated. Dominant species included Alexandrium catenella, Dinophysis caudata, Gymnodinium spp., Prorocentrum micans, Noctiluca scintillans, Prorocentrum gracile, Tripos furca and Gonyaulax spp. these species were previously reported. The sampling area of Mubarak village site was discovered for the first time for dinoflagellates community analysis. This site shows interesting results as some species were observed in high abundance. The high cell concentration of these toxic/HAB species suggests that our findings add substantially to the HAB dynamics in area and on this basis predicts future event. |
