One of the first per-requisite (important thing) in fish farming is water, fish lives and sustains it’s self in water.
Sources of water for fish farming include: ocean, river, streams, dams boreholes and wells. In fish farming two things are considered before deciding the water to use for the culture.
(1) Type of fish to be cultured
(2) Availability of quality water
If the farmer have in mind to culture fresh water fish, the farmer have to locate fresh water and if the fresh water is not available it becomes a big problem to culture the fish. Therefore not all can be cultured in fresh water some does well in salt water and cannot survive in fresh water. Providing a suitable environment for the fish to be cultured is very important.
AVAILABILITY OF QUALITY WATER
Water supplies for catfish ponds are usually of good quality, however, once the water used for culture, it’s quality deteriorates.this deterioration of environmental conditions is ultimately traceable to the use of feed. Despite the use of high quality feeds and carefully feeding practices, relatively little of the nutrient value of feed is converted to catfish flesh. The remaining nutrients derived from fish wastes stimulates excessive phytoplankton growth, high rates of phytoplankton metabolism cause pronounced diurnal fluctuations in dissolved oxygen concentrations, dissolved carbondioxide concentrations and ph, such fluctuations cause stress in fish resulting in reduced fish growth rates, poor feed conversation and reduced resistance to disease, in extreme instances, such as depletion of dissolved oxygen, fish may be unable to adapt and will die.

CONTROL AND MAINTANACE OF QUALITY WATER IN FISH FARMING.
Frequent change of water in fish farming increases the oxygen content of the water, therefore a flow through system of culture will help in replacing used oxegen and boost oxygen content of the water for fish culture. Natural waters soure such as rivers, streams can be diverted and be used in flow through system in an eathen and even concrete ponds settings. Thereby reducing cost for water maintenance and management. Lastly, water for fish farming must be a quality one for optimum fish production.
