Abstract

A study was carried out to determine the distribution of cyanobacteria in Sungai Sarawak Kiri. Sampling was done at 6 stations and involved two tributaries which are Sungai Bengoh and Sungai Turn. From the study there was a total of 23 cyanobacteria genera identified. Among the prominent genera were Lyngbya, Oscillatoria, Spirulina and Stigonema. From the 23 genera identified, there were 6 which were potentially toxin producers. They are Fischerella, Hapalosiphon, Lyngbya, Oscillatoria, Scytonema and Spirulina. High correlation between cyanobacteria species composition and three water parameters was determined namely, Phosphate concentration (R2 0.849758), Dissolved Oxygen (DO.) (R2 = 0.704859) and Biological Oxygen Demand (BOD) (R2 = 0.743838). The relationship between phosphate concentration and cyanobacteria composition was positive while analysis showed negative relationship for BOD and DO against cyanobacteria composition.
