The research aimed at the economic evaluation of marine aquaculture in the Triangle area in Damietta Governorate. The data was collected using a personal interview questionnaire during the months of September and October of the year 2020. This is for a regular random sample of 57 holders of marine fish farms in Damietta Governorate, representing about 5% of the total holders of marine fish farms. The descriptive and quantitative statistical analysis method has been used to estimate some averages, percentages and economic indicators that serve the research objectives. The research reached several results, the most important of which are: (1) The relative contribution of natural fisheries in Egypt and Damietta Governorate declined, as their contribution reached 22.74% and 15.14%, respectively. While the role of fish farming has been steadily growing, its contribution amounted to 77.26% and 84.86% of the total fish production in Egypt and Damietta Governorate, which amounted to 1599.69 thousand tons, 150.36 thousand tons as an average for the period (2010-2019), respectively. (2) The average value of the variable and fixed costs per acre in marine farms amounted to 208.70 thousand pounds, 23.70 thousand pounds, representing 89.80%, 10.20%, respectively, of the total costs, which amounted to 232.40 thousand pounds/feddan. (3) The average selling price of a ton of sea bream and sea bass was 100 thousand pounds, 70 thousand pounds for mullet, and the average production per acre of marine fish was 2.889 tons, while the total revenue from sold marine fish was 283.23 thousand pounds/feddan. (4) Marine aquaculture projects generate profit and an economic return. (5) The feasibility of investing in marine aquaculture activity was shown, as the average internal rate of return was estimated at 37%. (6) Investment efficiency indicators are more sensitive to changes in the farm selling price of marine fish than changes in the purchase price of feed and fingerlings, but the profitability of these projects remains economically feasible. (7) The critical value of the average selling price of bream and sea bass was estimated at 88.50 thousand pounds / ton, and mullet 61.95 thousand pounds / ton, while the critical value for the price of a ton of fodder was 25.40 thousand pounds, while the critical value of the mortality rate was 30%. (8) The problems of marine fish farming facing the respondents were of high relative importance and were represented in administrative and organizational problems, technical and operational problems, and economic and marketing problems. (9) The most important proposals of the respondents to overcome the problems of marine fish farming that they face are to provide and support the prices of feed, seed, and production requirements from the Authority - Establishing fish sales and marketing outlets near the areas of marine fish farms - Constantly cleansing the septic tanks and public drains and increasing the number of openings and septic tanks in the Triangle area and the road. Port Said International to constantly replenish the water - Establishing a fish hatchery that serves the marine fish farms area in Damietta to provide fry continuously and in a timely manner - Increasing the rental period for marine fish farms while working on ownership of lands for owners of marine fish farms.

The state is concerned with maintaining a clean environment and gives top priority to facing various environmental challenges resulting from the negative practices of citizens, production institutions and service bodies that pollute the environment, and represent risks to human health and depletion of natural resources. The problem of the study crystallizes in the inability to expand the establishment of forests trees on the land of the governorate despite the availability of all of the lands eligible for cultivation, as well as the surplus in the sewage water in that governorate. The study relied on two types of data, which are the published and unpublished secondary data issued to some authorities, such as the Ministry of Agriculture and Land Reclamation, and the primary data through the questionnaire formThe study concluded that the net revenue unit from the water unit for the woody trees represented in eucalyptus, kazorina, and pine, It amounted to about 34.18, 29.80, and 29.3 pounds for each unit of treated wastewater, while this net decreased for each of Kaya, Conocarpis, and Neem trees, reaching about 3.17, 7.3, 8.2 pounds for each unit of treated wastewater, as for the net revenue It reached about 44.33, 42.25, 38.92 pounds per unit of waterThe treated sewage for each of the casuarina, eucalyptus, and pine trees, while the revenues decreased for each of the neem, conocarpus and kayatrees, which amounted to about 17.94, 15.84, 11.59 pounds for each unit of treated wastewater, and the amount of water needed to produce a ton of wood from wooden trees was about 52.06, 34.95, 215.62, 113.63, 59.09, 78 m3 for each of the camphor, casorina, and kaya trees, Conocarpus, pine and neem, respectively [ABSTRACT FROM AUTHOR]
