ABSTRACT

Water quality includes all physical, chemical and biological factors that influence the beneficial use of water where fish culture is concerned any characteristic of water that affects the survival, reproduction, growth, production or management of fish in any way is a water quality variable (Boyd, 1990). There are many water quality variables in pond fish culture, fortunately only a few of these normally play an important role. These variables are what fish farmers should concentrated on an attempt to control to some extend by management techniques. These physicochemical parameters includes; Temperature, pH, Dissolve oxygen, Turbidity, color, Hardness and salinity. etc. Since water is the entire home/environment of Fishes it’s good to the fish farmers to understand some basic water quality management techniques in order to achieve successful fish farming.
