<p>Diversity, abundance and distribution pattern of the fish fauna are important aspects that need to be considered in order to frame the conservation and management strategies in any water body. To assess the composition, diversity and relative abundance of the fish fauna in the Manasbal Lake of Kashmir, the present study was carried out for two years (March 2018 - February 2020). A total of 22522 fish specimens were netted out during the sampling period, and the relative abundance and various diversity indices were used to assess the overall diversity of the inhabiting fish fauna.
