“…In all, Order Cypriniformes and Family Cyprinidae are found to be the most dominant group contributing 19 species of 9 genus. The dominance of Cypriniformes and Cyprinidae is supported by earlier works on fish diversity from same area Husain (1995Husain ( , 2003Husain ( , 2015Husain ( , 2018; Uniyal and Kumar (2006); Rana et al (2017 a, b) and Kumar (2017).

Fish that are predators of immature stages of mosquitoes are referred to as larvivorous fish. Both exotic and indigenous fishes are used as biocontrol agent of pre adult mosquitoes. This study was conducted with a purpose to estimate diversity, habit-habitats and abundance of endemic larvivorous fish. Present study was conducted during 2018-20, in the vicinity of three selected rivers i.e., Asan, Song and Suswa of Doon valley. Collected fish were sorted and identified following standard keys and catalogues. Habit-habitat, species abundance, diversity indices and similarity index were estimated using standard formulae. A total of 35 species of larvivorous fish under 5 orders, 8 families and 17 genera have revealed and listed based on habit and habitat found. Different study areas showed variation in abundance of fish diversity. Suswa’s sites contribute highest number of species (32) followed by Asan (28) and Song (27). Water bodies like pond, river, stream, tank, water canal, swamp and rice field are the main habitats in the study sites. Highest number of fish species is shared by river (35) followed by stream (26), pond (25), water canal (23), rice field (19), tank (18) and swamp (16) in succeeding order. Channa punctata is recovered from all the considered habitats. Some fish are found to restrict in particular habitats in all sites. While estimating relative abundance (RA), Pethia ticto species shows highest in Asan’s sites and Song’s sites but in Suswa’s sites Channa punctata showed highest abundance. None of the fish species shows dominant and eudominant status in abundance. Species richness, diversity, evenness, effective number of species are also estimated. Similarity index of species diversity among the selected riverine sites are also calculated. Prior the adoption of fish as biocontrol agents of mosquito, extensive knowledge on larvivorous fish, its features, diversity, distribution, habit and habitat are required.
