STUDY OF PHYSICO-CHEMICAL PARAMETERS OF TWO PONDS IN DARBHANGA DISTRICT OF BIHAR

Fresh water resources are scatted throughout the district and are under fishculture on extensive or semi intensive way giving some income to the growers. The number of ponds, tanks, etc. has significantly increased in last few years. The development of fisheries in these fresh water resources is the present need using scientific techniques. There is no limnological study of fish pond has been made to improve the pond productivity. The abiotic and biotic factors of the water influence the quality and quantity of aquatic life surviving there. The role of water in nature is unique not only for human; but, also for the numerous organisms living in the water. The physical and chemical properties of fresh water bodies are characterized by the climatic, geochemical, geo morphological and pollution condition. In order to utilize fresh water bodies successfully for fish production, it is very important to study the Physico-Chemical factors influencing the biological productivity in the water bodies (Sahni and Yadav, 2012).
