Reuse of Fish Farm Drainage Water in Irrigation

Abstract

Egypt is challenged by a shortage of water resources. Egypt will suffer from a severe water shortage especially after building El-NAHDA Dam in Ethiopia. To alleviate the strain on water and energy resources, innovative and sustainable strategies are required, such as seeking new sources of water. There are many new sources of water, which have not been tapped into. One of these sources is drainage water from fish farms. Three field experiments were carried out in research farms of the National Research Center in the Nubaria region to cultivating crops using these methods combined with new bio-fertilizing resources. The results indicate the benefits of fish water effluent as a suitable irrigator for potato, soybean, and onion crops. Furthermore, this application did not require additional fertilizers and thus reduced the fertilizer costs. The experimental results indicated that the best type of irrigation system for applying fish farm drainage water to fields was the sprinkler irrigation system.
