Invasion Potential, Impact and Population Structure of Non-native Fish Species, Cyprinus carpio (Linnaeus, 1758) from the Tributary of the Ganga River, Central India

Abstract

The non-native fish impact assessment and native fish stock management in respect of ecosystem function, biodiversity, recruitment pattern and fish stock, presently disputing both environmental executives (e.g. policy maker/government) and scientific communities especially in riverine sector and other large water bodies in developing countries [1-4]. Non-native species may become invasive and are capable of decreasing biodiversity through competition, spreading exotic diseases, predation and habitat degradation, genetic deterioration of wild populations through hybridization and gene introgression in short or long course of time [5-8]. Non-native fish species are also responsible for reduction of fish lenght, damage breeding ground and change food web structure and population structure of indigenous fish species and also earlier introduced fish species [9-13].
