Fish diversity dynamics and ecological assessment of Dejla Dewda Dam

Abstract

This study suggests the assemblage of fish diversity in Dejla Dewda Dam from 2017-2019. It also assesses the ecological status of the aquatic ecosystem using diversity indices such as species richness, Shannon-Wiener diversity index and Simpson’s dominance index, Simpson Diversity of Index, Evenness and Magralef Index were applied to analyse the fish community composition and diversity. The outcome suggest that fish population are abundant with variety fish species which show ecosystem is healthy and stable. Diversity indices essential for balanced fish community and maintaining favourable water quality standards, which are important for sustaining aquatic life. This study important for ecological health highlight the water quality standard should be maintained well for conservation of biodiversity. This outcome suggests potentiality of ecosystem and suggest future conservation strategy.
