Present   study reports new information on the
biovolume and carbon biomass estimates for dinoflagellates from Manora Channel,
Karachi coast, Pakistan. Biovolume per cell was
calculated using the geometric shape of dinoflagellates at species level. Both
thecate and athecate species were examined under light and scanning electron
microscope.  A total of 45 species were
measured and their cell size was ranged between 20-450µm.  Geometric forms of the species were seven
classed into as ellipsoidal, spherical, double cone shape, prolate sphere, cone
and half sphere, “cone+3 cylinder” shape, “ellipsoidal + 2 cone+ cylinder”
shape, “cylinder+ cone” shaped. Total biovolume ranged from 3.743 ×103 to 2.2 ×105 µm3
cell-1 and estimated cellular carbon content per cell ranged
from 397 × 102 to 26.5 x 104 pg C cell-1.  Carbon and biovolume relationship was
significant for thecate species which can thus be used for carbon flux
studies.
