Abstract
The diversity, abundance and distribution of phytoplankton along Kuala Terengganu
coastal waters have been sampled from 11
th
th
until 14
June 2015. The phytoplankton
samples have been collected within range 8 - 52 meters from the water surface. Water
sample (L) was collected and filtered through 60 µm mesh size plankton net. Filtered
phytoplankton sample was concentrated to 150 mL and preserved with 10% formalin
solution. Identification of phytoplankton to the genus level and cell counting using
Lackey's method was done under light microscope. Calculation was done for density
(cells/L), diversity index and evenness index. Phytoplankton density was counted
using Lackey's method. About 31 genera were present from all of the sampling
samples. Phylum Bacillariophyta was the most abundant. Most of abundant
phytoplankton genera present were Trichodesmium, Bacteriastrum, Chaetoceros,
Rhizosolenia, Proboscia, Thalassionema, Guinardia, Coscinodiscus and Ceratium.
