Abstract
A study of zooplankton in Sungai Sibu was carried out to determine the zooplankton composition, diversity and
to record selected water quality parameters. Sampling was done on 27th Nov 2011 and 2nd February 2012. A total
of 16 genera belonging to 7 class and 6 group were identified in this study. The groups were Copepoda,
Anotraca, Rotifera, Protozoa, Annelida and Artropoda.The group of Copepoda was recorded as dominating the
zooplankton communities in all stations which made up of 94% of total abundance. The zooplankton percentage
followed the orders : Copepoda > Anostraca > Rotifera > Annelida > Protozoa > Artropoda . Limnocalanus and
Calanoid were the common genera that found from every sampling site. Species diversity values range from
0.0377 to 0.920. Turbidity and pH have a strong positive correlation with zooplankton diversity. The correlation
value for turbidity is (r= 0.734) and pH (r= 0.650).
