A study was conducted to determine the phytoplankton community inhabiting the Pengkalan Gawi – Pulau Dula section of Tasik Kenyir, Terengganu. Phytoplankton is a plant type of plankton that forms the first level of food chain in aquatic ecosystem. The samples were collected monthly from March 2008 to January 2009 (11 months) at four sampling stations located at Pulau Dula (designated as station A), Sungai Ikan (station B), Pulau Pupi (station C) and Sungai Lawit (station D). The phytoplankton samples were collected at the water surface using vertical water sampler. The samples were first preserved with lugol’s iodine solutions before identified and counted using the inverted microscope (20X and 40X). A total of 5825.21 organism/ml of phytoplankton were counted and was dominated by chlorophyta (green algae) with 4168.40 ± 889.09 organisms/ml representing 71.6% from the overall total of phytoplankton investigated. This was followed by cyanophyta (blue-green algae) (521.17 ± 215.32 organisms/ml) (8.9%), bacillariophyta (diatoms) (442.99 ± 176.94 organisms/ml) (7.6%), chrysophyta (colonial) (315.86 ± 154.15 organisms/ml) (5.4%), dinophyta (dinoflagellates) (226.65 ± 232.38 organisms/ml) (3.9%) and euglenophyta (euglenoids) (150.15 ± 91.99 organisms/ml) (2.6%). The abundance of chlorophyta in this study was highly different (p<0.05) with the rest of the groups. Cyanophyta showed no different (p<0.05) with bacillariophyta but have some differences (p<0.05) with the other groups of phytoplankton. Euglenophyta and dinophyta in this study however showed no significant differences (p<0.05) between themselves. The results of this study can be used as basic information in managing the Pengkalan Gawi – Pulau Dula section of Tasik Kenyir in sustainable ways. This is to ensure that the functions of phytoplankton in terms of providing food energy to the higher trophic level of food chain in this lake section remains.
