Abstract: Biodiversity is crucial for maintaining ecosystem stability, protecting overall environmental quality, recognizing the inherent value of all species on earth. Fish are the important biological resources used for ecological assessments at all levels of biological organization at the various levels of ecosystem. They can serve as bioindicators of water quality and environmental health and also used to monitor the water quality for toxic substances in aquatic ecosystems. Fish are considered as rich sources of protein and essential food for humans, providing fats, vitamins A and D, which are vital for daily life. Additionally, fish are also used in various medical treatments. Global freshwater biodiversity of fish is in decline due to various factors like alterations in water flow, pollution, unsustainable fishing practices, spread of invasive species, and the effects of climate change. The objective of this review work is to give better knowledge in understanding the fish diversity in relation to abundance, and richness of the fresh water aquatic ecosystems in India.
