Fish harvesting facilities in earthen ponds (harvest ditch) in Egypt

Fish harvest in earthen ponds is significantly facilitated by establishing harvest ditches. In addition to facilitating fish harvest, ditches help in drying pond bottom. Depending on pond size and the slope of pond bottom, placing harvest ditches are determined. Ditches could be peripheral especially in large ponds or central in smaller ponds. Establishing harvest ditches is not recommended if water table is high otherwise unfavorable situations which will result in difficulty in drying pond bottom.
