Productivity analyses of Baigul reservoir through remote sensing technique

Abstract

Present study was carried out on Baigul reservoir to know the productivity level with in the reservoir in terms of fish production based on physico-chemical parameters of water using remote sensing data. The reservoir has an average water spread area of 1415.59 hectares, which was computed through remote sensing data of satellite IRS- IC LISS III for the year 2006-2007. Thematic maps of distribution of individual physico-chemical parameter of water were prepared using interpolation technique. Criteria based modeling was carried out for optimum range of physico-chemical properties of water those are related to the productivity, decided by the several workers. The modeling intern output of the productive zone an area of 1139.78 hectares falls in medium productive zone in the reservoir. Considering the level of productivity of reservoir in terms of fish was computed that was almost equal to the present fish production from the reservoir. The study may open the avenues of measuring productivity of the reservoirs for their judicious utilization of fishery resources in the Indian reservoirs.
