A pond is referred to as a man-made or natural water body. Water quality means the component of water which must be present for optimum growth of aquatic organisms. The source of water supply to the pond may be from river or from spring or from rain. A pond must be manageable for controlled farming; Life in aquatic environment is largely governed by physico-chemical characteristics and their stability. Various changes that organisms bring about in the water are essential for their own existence. Rearing of fishes in localized water is known as Pisciculture. The determinant of good fish growth in water body includes dissolved oxygen, total hardness, alkalinity, temperature, etc. Conversely other parameters like BOD, COD indicates pollution level of a given water body. Concentrations of physico-chemical parameters increase due to human activities and also by lack of environmental regulations.
