Abstract:
The identification of 175 freshwater fishes from 41 west flowing and 3 east flowing river systems of Kerala were confirmed. These can be grouped under 106 ornamental and 67 food fishes. The biodiversity status of these fishes was assessed according to IUCN criteria. The results showed that populations of the majority of fish species showed drastic reduction over the past five decades. Thirty-three fish species were found to be endemic to the rivers of Kerala. The distributions of the species were found to vary within and between the river systems and some of the species exhibited a high degree of habitat specificity. The diversity and abundance of the species generally showed an inverse relationship with altitude. The serious threats faced by the freshwater fishes of Kerala are mostly in the form of human interventions and habitat alterations and conservation plans for the protection and preservation of the unique and rare fish biodiversity of Kerala are also highlighted.
