The research aimed to study three fish farms, which are the only ones in the villages of Qanaf Governorate. They are pioneering, indicative and exemplary farms. The research sheds light on them, especially as they depend on feeding them on poultry waste to reduce the focus on concentrated feed, reduce costs and reduce waste. It is one of the goals of the green economy, represented in minimizing environmental pollution and recycling waste. Three types of tilapia, catfish, and basa fish are studied. One of the most important results of the research is that despite the state's efforts to increase fish production using the fish farming method, there is still a gap between fish production and consumption, so attention must be paid to this method alongside natural fisheries to reduce this gap and increase the per capita share of animal protein. By studying and estimating the items of the revenue structure and costs of various types in the two tilapia farms, it turns out that the year 2020 saw an increase in the sales of both farms, and Sheikh Essa’s sales were the highest in the two years by a small percentage. Estimating the indicators of the productive efficiency of the two farms shows an increase in total costs, an increase in net profit, and an increase in the producer’s incentive for the two farms in 2020. And by studying and estimating the items of the revenue structure and costs of all kinds in the two catfish farms, it turns out that in 2020 the sales of each of the two farms increased, and by estimating the indicators of the productive efficiency of the two farms, this means an increase in total costs, an increase in net profit, and an increase in the product incentive for the two farms in 2020. And by studying and estimating the items of the revenue structure and costs of different types in three basa fish farms in 2020. The revenues of Sheikh Essa's farm are the highest, with a value of 568,260 pounds. The product incentive for Al-Ghab farms, Sheikh Essa and Al-Zahaliq reached 39.3%, 41.3%, and 28.7%, respectively, and the total product incentive reached 40.0%.
