Abstract:
This findihg of this study is to provide the current status of phytoplankton
community in tenn of abundance, species composition and distribution. In order to study
the alien species identification, this study can be used as baseline data to determine the
native species that already present at Teluk Kalong's waters. This study was conducted at
Teluk Kalong, Kemaman, Terengganu. The in situ. parameter did not affect the
phytoplankton density and distribution. A total of 3 Phyla, 4 Classes, 33 Family and 44
Genus of phytoplankton were recorded. For species composition, it was distributed
evenly based on its appearance in the mesh size. 24.14% - 37.93% portion of
phytoplankton presence in 60μm. 27.59% - 43.10% of phytoplankton filtered in 40μm
and 29.41% - 36.36% in 20μm. Phytoplankton density ranging from 1743.432 Nat.
Unit/L to 8906.493 Nat. Unit/L. Station 3, 12, and 14 has highest densities, which the
nearest station to the land. Bacillariophyceae, 84.53%, dominated by Guinardia sp. and
Rizhosolenia, was the highest percentage in all station, followed by Cyanophyceae, by
10.50%, Dinophyceae by 4.06% which dominated by Dinophysis sp. and Ceratium sp.,
and Dictyochophyceae by 0.003%. Value of 3.42 in station 3 had the highest diversity
while for 2.78 and 2.96 in stations 5 and station 8, had the lowest diversity of
phytoplankton. The value of the phytoplankton diversity was grouped under second
Diversity Form, which is rich in diversity. In this study, none of the phytoplankton was
new in the Teluk Kalong waters.
