| Abstract | ||
| The fish sector contributes with a value of about 48,251 million pounds, or about 9.6% of the value of agricultural income, while the net income of the fish sector amounted to about 44,481 million pounds, or about 13.75% of the total value of net agricultural income. The problem of the study was that the total annual Egyptian product of fish has not yet been able to cover the consumption needs in light of this huge potential. As fish production reached about 2038.991 thousand tons in 2019, while consumption reached about 2509.9 thousand tons for the same year, and the decrease in the quantities offered of fish annually has led to an increase in the required quantities of fish. As a result of many factors, the most important of which is the population increase and the increase in fish prices, which is not commensurate with the purchasing power of low-income people, there is a problem with two main dimensions: low production efficiency and low marketing efficiency. Fish production is also unable to meet the population’s needs of this commodity, which results in a rise of prices of local varieties and an increase in the quantity of fish imports until it reached about 505,959 thousand tons in 2019; the amount of exports reached about 35,009 thousand tons in 2019. While the average per capita share of the GDP is about 20.26 kg per year for the year 2019; the average per capita available for consumption in 2019 was about 25.38 kg. This study aims to highlight the main features of fish production in Manzala Lake, identify the most important obstacles to fish production, determine the factors affecting fish production, and estimate the optimum production volume In the Egyptian lakes during the period (2005-2019) in order to provide some economic indicators to the planning and existing bodies for the development of the fisheries sector in Egypt and to develop this important sector of the national economy, as well as to identify strengths, weaknesses, opportunities and threats in Manzala Lake through the use of (SWOT) Analysis. By studying the time evolution of the quantity of fish production from the total production of Manzala Lake, it was found that the quantity of fish production from the total production of Manzala Lake ranged between a minimum estimated about 36.8 thousand tons in 2007, and a maximum of about 81.4 thousand tons of the total production of Manzala Lake in 2013. While the average amounted to about 55.3 tons during the study period. And that the amount of fish production from the total production of Manzala Lake is increasing by a statistically significant amount about 1.9 thousand tons annually. As the whole model has been statistically significant, with a growth rate of about 3.4%, and the coefficient of determination indicates that about 40% of the changes in the amount of total fish production, the total production of Manzala Lake, are due to the influence of factors that reflect time. And by studying the relative importance of fish production from Manzala Lake out of the total northern lakes, it appears that the production from Manzala Lake was about 42.2%, with a minimum of 34.2% in 2016 and a maximum of 56.2% in 2013. | ||
