Abstract
Cage culture of fish is one of the proven methods of aquaculture. Cage culture is being looked up as an opportunity to utilize existing inland water sources with great production potential to enhance production from inland open waters and posed as an answer to the rising demand for animal protein in the country. Freshwater cage culture is an important industry as it provides a source of protein and fulfills the high market demand for freshwater fishes. Poor water quality can result in low profit, low product quality and potential human health risks. Success, however, of the new aquaculture businesses greatly depended upon the suitability of the reservoir’s water quality, its water quality variabilities, pollution and seasonal climatic and mixing events occurring in the new aquatic ecosystem. This paper gives detailed information on water quality parameters such as water temperature, pH, dissolved oxygen, biological oxygen demand, chemical oxygen demand, alkalinity, hardness, nitrite, nitrate, ammonia, phosphate, sulphate, total dissolved solids and total suspended solids in freshwater fish culture as well as cage culture.
