Ecological characterization of Moyar and Cauvery river using box plot model approach

Freshwater systems are arguably among the most endangered ecosystems on the Earth. Human activities on water lands/streams/rivers changed the hydrologic and ecological processes. Hence sound management of aquatic resources is necessary to understand the condition of habitats, the extent of changes in habitats and the factors influencing the changes. In order to arrive a better understanding of the biological processes, the study was carried out to a total of 16 Water and Habitat characters considered for analysis using Box Plot Model approach. During the sampling, a total of 22 sites as a whole was selected and sampled with 15 in River Moyar and 7 in River Cauvery. It has been observed that River Moyar is highly supplied with primary and secondary orders of streams and is rich in water quality and habitat structure which are unique in nature. No man-made habitat alterations with effects onto the fish community and assemblage structures have been identified. Hence by comparing the water quality and habitat characteristics of Moyar and Cauvery River system, it is concluded that the Moyar river system is rich in the water quality and habitat structure compared to the Cauvery river system.
