Abstract:
The seasonal variation of Noctiluca scintillans was investigated from coastal areas of Karachi (Manora Channel), Pakistan. Total cell abundance ranged between < 100 cells l-1 to 1340 cells l-1 during the sampling period May 2002-July 2003. High cells densities were recorded during May 2003. No green or red water discolouration was observed. Cell size biovolume ranging between 100 µm-600 µm was used to convert to carbon biomass 4.5-6.8 pg C cell-l. Greatest Insitu growth rate of N. scintillans (µ day-1) during 2006 was calculated at 0.82 µ day-1.
