Evaluation of Physico-chemical Parameters of Water and Soil in Relation to Fish Production of Guthia Taal of Dstrict Bahraich, U.P.

Abstract

The physico-chemical condition of water and soil plays a vital role in the wetland ecosystem. Three sampling stations were selected for the study of physico-chemical parameters of water and soil of Guthia taal in relation to fish production. Various physico-chemical parameters of water like temperature, transparency, pH, dissolved oxygen, free carbon dioxide, biochemical oxygen demand, chemical oxygen demand, total alkalinity, total hardness, nitrate and phosphate were measured. The soil samples were analysed with respect to soil texture, pH, organic carbon, available phosphorus and nitrogen. The present finding established that, in spite of fevourable physico-chemical condition of water and soil, potential fish yield is not being realized. Fish production can be augmented to a great extent if we managed scientifically. It can be realized optimally by stocking of fast growing Indian major carps (Catla, Rohu, Mrigal and Calbasu) and Exotic carps @ 1000 1500 fingerlings/ha to utilize all the available fish food resources.
