Abstract

A study was carried out to examine the ratio of diatom to dinoflagellate in two estuaries as sampling areas and its potential application as an early indicator for eutrophication. Water samples were collected from the estuaries of Samariang Batu and Santubong fortnightly for 10 samplings using Van dorn sampler. Cell enumeration and identification was carried out by using sedqwick rafter counting chamber under light microscope based on the relevant reference material. Our result clearly showed that the diatom to dinoflagellates ratio increased with the increasing of macronutrient in the water and affected by the environmental factors. High Si: P ratio resulting in high cell density of diatom. Diatom Nitzschia spp, and Pleurosigma spp are proposed as the potential bioindicator species for eutrophication in Santubong and Samariang Batu since they were commonly found in estuaries water. Further study on Diatom and dinoflagellates ratio of other estuaries water is important reaffirm the finding on the study
