Although the application of treated wastewater in irrigation is a common practice in Jordan, there are no studies on its use in fish culture. In this study, physical, chemical and biological characteristics of an artificial lake containing mixture of treated wastewater and rainwater were assessed to examine whether the nutrient loading is sufficient for fish culture. The study also evaluated the suitability of the lake's water quality for irrigation after fish farming. The study was conducted in outdoor tanks fed with water from the artificial lake and stocked with three types of fish (Tilapia, Carp and Koi). The diversity of phytoplankton communities in the lake's produces natural food for Carp and Koi and promotes their growth with maximum per cent survival of 89% and 56% respectively. In addition, remarkable improvement in all water quality parameters after fish culture was observed.

鱼类养殖和灌溉用人工湖水质的首次评估：以中东缺水地区的中水回用为例

尽管将处理过的废水用于灌溉是乔丹的普遍做法，但尚无关于将其用于鱼类养殖的研究。在这项研究中，评估了包含处理过的废水和雨水的混合物的人工湖的物理，化学和生物学特性，以检查养分含量是否足以养鱼。该研究还评估了养鱼后湖泊水质是否适合灌溉。这项研究是在室外水箱中进行的，水箱中的水来自人工湖，并养有三种鱼类（罗非鱼，鲤鱼和锦鲤）。湖中浮游植物群落的多样性为鲤鱼和锦鲤提供了天然食物，并促进了它们的生长，最大存活率分别为89％和56％。此外，
