Abstract:
Phytoplankton is a wandering micro-organism that moved by current that functions as
aquatic food chain and primary producer. A study was done in Setiu Wetlands where 12
stations were established during non-monsoon (6 September 2003), intermediate
monsoon (9 October 2003) and monsoon season (3 December 2003). The water samples
were obtained from approximately 0.5 - 1.0 meter deep. Water (42 L) was filtered using
by a 20 μm nanoplankton net. The phytoplankton was preserved with Lugol's iodine. The
total number of phytoplankton was counted and identified using Lackey's drop. All the
data was calculated using Shannon diversity index, Evenness index, correlation and
regression. The species richness in Station 5 was the highest during three seasons.
