The biomass of zooplankton were studied using samples collected in horizontal hauls<br />

in the water of Port Dickson, Straits of Malacca between December 2012 until<br />

December 2013 with 140 µm mesh. Duplicate sub - sampling technique were used by<br />

using 2ml stempel pipette. The zooplankton were identified to the lowest taxonomic<br />

levels as possible and counted under stereo microscope. At least 200 zooplankton<br />

were enumerated in each sample. An average length of zooplankton samples (≤ 20<br />

individuals) of each taxon were collected and the length of an appropriate body portion<br />

were taken by using a stereo microscope with suitable magnification. The length were<br />

converted into carbon weight of individual zooplankton by using previously reported<br />

length-weight regression equations and multiply by zooplankton abundance. Biomass<br />

were generally higher during July 2013, November 2013 and December 2013.<br />

Polychaete, larvacean and chatognaths contributed the higher zooplankton biomass<br />

although the abundance was minor.<br />
