Population Studies on the Puntius Conchonius (Hamilton) from Cauvery and Malampuzha Dam, South India

Abstract

Puntius conchonius was collected from Cauvery (Belagola) River, Karnataka and Malampuzha Dam of Kerala, South India. There are two major fishing points that were remarkable in the river systems which are selected for the present work. There are two types of rivers in which inhabit natural, ornamental and edible fish like P. conchonius. To examine the population structure of P. conchonius, the specimens were collected, preserved and analysed for biometric characteristics. In this context, 50 biometric characters were documented for all individuals and were compared between two riverine populations. Besides, the plan of study was mainly focusing on population diversity and biometric similarity of the P. conchonius. The findings of this study to identify among populations, more precisely as a colour can be as an enigmatic character of this species. As a result, there could be a possible link that was assessed between populations; the experimental biometric character like meristics was a similar one based on the ecological habitat and prey–predatory relationship.
