The increasing demand for animal protein in Egypt and around the world, including livestock, poultry, fish, and other farmed animals, has led to massive development in manufactured feeds, as global production of commercial manufactured feeds is estimated at more than one billion tons annually, with an estimated marketing value of more than 400 billion American dollars., The percentage of aquaculture feed is about 4% of the total global production of manufactured feed. This percentage contributes to feeding about 96 million tons of fish produced in the world. The quality of fish feed is considered an essential factor in doubling production capacity and increasing the profitability of fish farms at rates exceeding 60% annually in some systems, which has helped in the great spread and development of fish farming systems in various countries of the world, both developed and developing. Therefore, the study mainly aimed to study the economic efficiency of the fish feed factories under study in Egypt according to the cost-benefit analysis according to its divisions of large, medium, and small production capacity, and to estimate the technical, distribution and, Economic Efficiency of the fish feed factories under study according to the data envelopment analysis. Implementing a SWAT Analysis to identify the strengths, weaknesses, opportunities and, threats facing the fish feed industry in Egypt.   The study based on descriptive and quantitative Economic Analysis methods by using the Economic methods used in the Economic Evaluation of fish feed factories, Estimating the Technical, Economic, and distribution Efficiency considering the stability and change of capacity returns for fish feed factories in Egypt in the research sample using the data envelopment analysis (DEA) method. The study reached many results, most notably: There has been development in the fish feed sector in Egypt, as the number of fish feed factories for the private and government sectors increased during the period (2008-2022), from about 56 factories in 2008 to about 112 factories in 2022, and they are divided into Fish feed production factories in Egypt include factories for producing pelleted feed, which is sinking feed, and factories for producing feed using extruder technology, which is floating and sinking Pelleted feed. The number of pelleted and extruder production lines within fish feed factories for the public and private sectors is about 133 lines, including about 57 extruder lines, representing about 42.8%, and about 76 pelleted lines, representing about 57.0% of the total number of lines. The return on investments for large, medium, and small feed factories is in the study sample, about 58.4%, 49.1%, and 32.6% respectively, the ratio of revenues to costs for large, medium, and small feed factories is about 1.16, 1.14, and 1.11, respectively. The average amount of technical efficiency for producing fish feed factories in constant return to capacity reached about 0.974 for large factories, 0.835 for medium factories, and 0.794 for small factories. Production capacity, this means that producers of large, medium, and small fish feed factories can increase fish production by an estimated rate of approximately 2.6%, 16.5%, and 20.6%, respectively, without any increase in the quantity or number of resources used to produce fish feed factories. By reviewing the average amount of distributive efficiency to produce fish feed factories in the constant return to capacity for large, medium and small factories, the production capacity of the research sample amounted to about 0.895, 0.862, and 0.931, respectively. This means that recombining the economic resources used in producing fish feed factories will save about 10.5%. 13.8% and 6.9% of the production cost of fish feed factories at the level of large, medium, and small factories production capacity in the research sample, the average amount of Economic Efficiency to produce fish feed factories in constant return to capacity at the level of large, medium, and small factories. The production capacity of the research sample was about 0.872, 0.719, and 0.739, respectively. This means that feed producers can achieve the same production level as fish feed factories while reducing fish feed production costs by an estimated rate of about 12.8%, 28.1, and 26.1 for large, medium, and small production capacity factories in the research sample, respectively.
