Phytoplankton and seagrass play important role in aquatic system. The abundance of
phytoplankton is influence by the characteristic of seagrass. A study on abundance of
phytoplankton in sea grass bed was carried out in the coastal water of Setiu Wetland,
Terengganu. Nine sample of seawater were collected from three stations on February
2018. This study was aimed to determine the abundance, richness and diversity of
phytoplankton. Parameter such as salinity, DO, temperature, pH, TSS and chlorophyll
a was measured at each of the station. A total 11 genus composed by 15 species of
diatoms and 1 species of cyanobacteria were found at the stations. The highest cell
density was 152 500 cell/ml at station 2 and the lowest cell density was 60 000 cell/ml
at station 1. Chaetoceros sp.1 was the dominant species with 64% of total abundance
followed by Skeletonema sp. with 13% and Letocylindru sp. with 3.67%. According
to PCA (Principle Components Analysis), factors that influence the abundance of
phytoplankton is suspended solid.
