The loss of biodiversity is one of the most reflective effects of humans on the global perspective and it is more and more urgent to understand how this loss will affect and what will be the profound consequences to the ecosystem functioning. Non-native fishes can cause considerable adverse impacts on the function of aquatic ecosystems and loss of biodiversity. Ecology of ecosystem focuses on the fluctuation of energy and nutrients through ecological systems. It has been confirmed that the fishes are sensitive indicators of environmental degradation and alteration. Study was undertaken during the period of October 2015 to September 2016 from the Paisuni river, India. Fish faunas of the Paisuni river have harbors of 58 species belonging to 5 order, 18 family and 43 genera. Cypriniformes and Cyprinidae were the most rich fish species order and families, respectively from the river. The Cyprinidae family has highest harbors family with 25 fish species. The family Anabaniitidae has 5 fish species which is second dominant family from the Paisuni river. According to abundance, Cyprinus carpio and Oreochromis niloticus were powerfully invaded in the Paisuni river. The detonated frequency of O. niloticus and C. carpio was recorded from the Paisuni river. Exotic species is alarming for indigenous fish species biodiversity. C. carpio and O. niloticus are frequently recorded in the Ganga river. Very highly important and ecological indicator fish species, Tor mahseer, Tor tor is declining in the catch. Current ecosystem functioning is favour to non-native species from the Paisuni river.
