| Summary: | A two year study (January 2008 - December 2010) of plankton and primary
productivity was conducted in Kelantan and Pengkalan Chepa rivers. These two
rivers are considered as main river of Kelantan River Systems. Kelantan River is
influenced by intensive sand mining and urbanization which at this moment could be
categorized as CLASS Ill river. Meanwhile Pengkalan River is influenced by
industrialization and was categorized as CLASS Ill river by Department of
Environment. Zooplankton and phytoplankton are included in this study. However,
the identification is yet to be completed. At this moment, there were 955 individuals
of zooplankton were identified in Kelantan River, which representing 13 families and
50 species while 1260 individuals were identified in Pengkalan Chepa River which
consists of 11 families and 35 species. The most dominant and abundant species in
Pengkalan Chepa river was Monostyla lunaris while Lecane elasma dominated the
Kelantan River. The net primary productivity value for majority of the stations in the
study site showed the negative value. This indicates that the more oxygen was
consumed than produced. |
