Productivity and Cage Site Selection, Assessed by Geospatial Tools in Sapan Reservoir, Amravati, Maharashtra, India

Abstract

The present study was conducted on Sapan reservoir located on river Sapan, Amravati, Maharashtra, India. Present study deals with application of geospatial technology for discrimination of different hydrological parameters and past status of fish fauna of reservoir. Reservoir is divided into riverine, transitional and lacustrine zones based on the water mixing pattern and water quality. The least productive area was found in riverine, transitional and lacustrine zones of the reservoir that might be because of low nutrient soil and high mean depth. Approximately, more than 50% area of the reservoir falls under moderately and high productive category, therefore this reservoir can be considered under the mesotropic class, in which 37% of the reservoir area has been identified suitable for cage culture, based on suitability study.
