Biomass estimation of coral reef fishes in Redang and Bidong Island by underwater Visual census methods

Abstract

A research regarding the estimation of biomass of coral reef fishes particularly in Redang and Bidong Island by method of underwater visual census. Estimation refers to estimating the length of fish and its amount, in-situ as accurate as possible with the help of proven method from past research. After recording the data of length and abundance, the data was integrated to biomass and CHI by length weight relationship. Diversity was also done to show species richness, diversity and evenness. CHI was also conducted to show the healthiness of coral reef base on biomass of the fishes. Results of biomass, diversity and CHI were successfully obtained in this research.
