摘      要：Morphotaxonomy and seasonal abundance of dinoflagellates of the genera Prorocentrum and Mesoporos(Prorocentrales) were studied from nutrient-rich waters,Karachi Harbor and the mouth of the Manora Channel,Pakistan during May 2002-July *** both light and scanning electron microscopy,13 species of Prorocentrales were identified according to cell shape,size,ornamentation of thecal plates,and architecture of apical platelets,apical pore area,marginal pores,and intercalary ***,***,***,***,***,***,***,***,***,and Mesoporos perforatus constitute new records for sindh coast of *** most abundant species were ***/***(4.5×103 cells/L),***(1.1×103 cells/L),***/***(2.5×102 cells/L) and ***(6.6×103 cells/L) at temperatures of 29-31℃ and salinities of *** abundance was observed in winter and lower abundance in *** was no significant change in the distribution of species between stations except for the benthic species which occurred close to Karachi Harbor *** positive correlations were observed between Prorocentrum *** temperature(R 2 =0.27) and negative correlations with salinity(R 2 =-0.32) except for *** and *** which has negative correlation with temperature(R 2 =-0.24) and positive with salinity(R 2 =0.08,0.19).The finding of potential okadaic-acid producing species of benthic Prorocentrum call for monitoring for possible human health problems in this region.
