Water Quality In Aquaculture

Water quality includes all physical, chemical and biological aspects factors that infuence the beneficial use of water where aquaculture is concerned especaily for fish production . Any characteristic of water that affacts the survial , reproduction, growth, production , or managemet of fish in aquaculture any way is a water quality variable .The different in the physical, chemical and biological chemical and biological properties i.e., phytoplankton and zooplankton organisms of water result in different response to the soil properties and fish production. The present work was carried out to study the effect of different irrigation water ,i. e. Nile fresh water only ore mixed with drainage water on some physical and chemical proparties for pond soils in aqaculture. Also, effects of cultivation on changes in chemical and hydrobiological compostion of different irrigation water were taken in consideration, as well as fish production.
