المستخلص: تكمن مشكلة البحث في انخفاض إنتاجية أغلب المصايد السمكية المصرية، بالرغم من تعدد وتنوع المصايد الصالحة للصيد في مصر والمتمثلة في البحار والبحيرات والمنخفضات الساحلية ونهر النيل وفروعه ومزارع الاستزراع السمكي بأنواعها المختلفة، إلا أن هناك فجوة سمكية. وكانت أهم النتائج التي توصل إليها البحث ما يلي: أن هناك فترتين متميزتين للتقلبات الإنتاجية السمكية الموسمية الأولى تضم الشهور مايو، يونيو، يوليو، أغسطس، وتتسم بانخفاض الناتج في تلك الفترة عن المتوسط العام بنسب موسمية بلغت حوالي ٨٦,٩١%، ٧٣,٤٥%، ٦٦,٨٨%، ۷۷,۸۸% على الترتيب للبحار. بالنسبة للبحيرات شهور يناير، فبراير، مارس، أبريل، مايو، يونيو، يوليو، أغسطس وتتسم بانخفاض الناتج في تلك الفترة عن المتوسط العام، حيث بلغت النسب الموسمية حوالي ۹٤,٧٢%، 95.88%، ٩٦,٣٩%، ٨٧,٥٠%، ٩١,٦٧%، ٩٢,٦٩%، ٩٤,٦١%، 96.98% على الترتيب للبحيرات، وشهور يناير، فبراير، أبريل، مايو، يونيو، سبتمبر، أكتوبر، نوفمبر، ديسمبر وتتسم بانخفاض الناتج في تلك الفترة عن المتوسط العام بنسب موسمية بلغت حوالي، ٩٢,٥٠%، ٨٤,٨٤%، ٩٥,٦١%، ٩٦,٨٨%، ١٠٣,٨٦%، ١٠١,٦٦%، ١٠٧,٠٦%، ١٠٢,٦٥%، ٩٤,٧٦%، ٩٦,٩٨% على الترتيب لنهر النيل وفروعه. أما الفترة الثانية فتضم شهور يناير، فبراير، مارس، إبريل، أكتوبر، نوفمبر وديسمبر، وتتسم بارتفاع الناتج السمكي البحري عن المتوسط العام بنسب موسمية بلغت ۱۰۷,۸۲%، ۹۸,۳۹%، 103.05%، 102.15%، 95.81%، ١٤۷,۳۹%، ١٢٩,٥٤%، 110.66% على الترتيب للبحار، وشهور سبتمبر، أكتوبر، نوفمبر، ديسمبر وتتسم بارتفاع الناتج السمكي البحيري عن المتوسط العام بنسب موسمية بلغت حوالي ۱۰٧,٦١%، ١١٦,٢٦%، ١١٣,٢٤%، ١٠٧,٦٢% على الترتيب شهور يوليو أغسطس، وتتسم بارتفاع الناتج السمكي النيلي والترعي والمصرفي عن المتوسط العام بنسب موسمية بلغت حوالي ۱۱۱,۳۲، 111.59% على الترتيب.

The fisheries sector is an important sector for both food security and economic development in Egypt. because it is important to contribute to the supply of animal protein. Fish is an important source of animal protein needed to build the body to maintain human health. The research aims to shed light on the production capacity of fish in Egypt from its various sources. assess the fish consumption function in Egypt. and shed light on the most important problems that impede the development of fish wealth in Egypt. A study of the relative importance of fish production in Egypt from its various sources revealed that the total fish. production in marine fisheries amounted to about 115.38 thousand tons during the period (2005-2018) representing about 8.51% of the average fish production in Egypt of about 1356.19 One thousand tons during the previous period. and the average production of lake fisheries was about 168.68 thousand tons. representing about 12.44%. and about 80.20 thousand tons for the production of the Nile River fisheries and its branches. representing about 5.91%. The average production of fish farming in Egypt was estimated About 991.94 thousand tons. which represents about 73.14% of the average fish production in Egypt. which is about 1356.19 thousand tons during the period (2005-2018). The estimation of the consumption function of fish in Egypt during the period (2005-2018) showed that there is a positive and statistically significant relationship between the amount of fish consumption and per capita income. that is. an increase in the annual per capita income by 1% leads to an increase in the amount of fish consumption in Egypt By 0.5 thousand tons. By studying the seasonal fluctuations in marine fish production. lakes. and the Nile River and its branches during the period (2016-2018). there are two distinct periods. The first of them includes the months of May. June. July and August. and it is characterized by a decrease in the output during that period from the general average with seasonal rates of about 86.91%. 73.45%. 66.88% and 77.88% respectively for the seas. As for the lakes. the months of January. February. March. April. May. June. July. and August are characterized by a decrease in the output during that period compared to the general average. as the seasonal ratios reached about 94.72%. 95.88%. 96.39%. 87. 50%. 91.67%. 92.69%. 94.61% and 101.86% respectively for the lakes. The months of January. February. April. May. June. September. October. November and December are characterized by a decrease in the output during that period from the general average with seasonal rates of about 92.50%. 84.84%. 95.61%. 96.88%. 103.86%. 101.66%. 107.06%. 102.65%. 94.76% and 96.98% respectively for the Nile River and its branches. The decrease in output during that period is attributed to many factors. the most important of which are: (A) Natural factors represented in temperature. light. marine currents. density. salinity. dissolved gases and mineral elements. and the effect of these factors is evident. especially the high temperature in the summer months. where production decreases with high temperatures. which leads to less Demand and the difficulty of marketing services. (b) the administrative factors represented in stopping fishing in this period specifically.

as it corresponds to the time specified for the reproduction and unloading of most fish species in the seas. The second period includes the months of January. February. March. April. October. November. and December. and is characterized by higher marine fish production than the general average. with seasonal rates of 107.82%. 98.39%. 103.05%. 102.15% and 95%. 81%. 147.39%. 129.54% and 110.66% respectively for seafarers. The months of September. October. November and December are characterized by higher marine fish output than the general average. with seasonal rates of about 107.61%. 116.26%. 113.24% and 107.62% respectively. The months of July and August are characterized by higher levels of Nile. grazing and banking fish production than the general average. with seasonal rates of about 111.32% and 111.59%. respectively. he presence of a positive correlation between the seasonal fluctuations of the total seas and the seasonal fluctuations of the total lakes in the average period was estimated at 0.61. and the absence of a correlation between the seasonal fluctuations of the total seas and the seasonal fluctuations of the Nile River and its branches. estimated at about -0.06. as well as the absence of a correlation between the seasonal fluctuations of the total. the lakes and the seasonal fluctuations of the Nile River and its branches. which were estimated at -0.02 during the period (2016-2018) A study of The most important problems facing fish production in Egypt revealed that the most important problems of sea water are pollution of sea water with sewage and waste water. draining seas and deducting large parts of them for the purpose of reclamation. and the lack of trained workers. Pollution resulting from the navigation movement of ships such as fuel and oil leakage from engines And filters. and that the most important problems facing the lakes are the drying up of the seas and the deduction of large parts of them with the aim of reclamation. Pollution with wastewater and sewage. In the sea. and that the most important problems facing the Nile River and its branches are pollution of the Nile water with industrial waste and sewage water. Collecting fish from fishermen inside the collection centers (the fish ring) and selling it at a low price for the account of a wholesaler. imposing fees inside fish collection centers. not renewing some fishing licenses This is due to the low living conditions of fishermen. the low amount of loans provided by the Fishermen's Cooperative Society. and that the most important problems of fish farming are the high costs of feeding. The feed. the instability of fish marketing prices. the increase in the rental value of the farms. the high prices of fingerlings for some families. such as the Burien family.

In light of the results obtained. the study recommends the following: (1) Evaluating the effect of environmental and economic variables on natural fisheries and not neglecting the great effect of different forms of pollution on natural fisheries. (2) Conducting scientific research and explorations on all fisheries to identify the size of these current economic resources and the fish stock. (3) Enhancing the role of water police to protect sea fisheries from the dangers of pollution in the sea environment and prohibit and punish illegal fishing. (4) Improving means of wireless communication between fishing units and ports and making available necessary equipment in fishing ports (ice factory. boat repair workshops. pavement. fish packing factories). Particularly in South Red Sea. (5) Preparing training courses to increase and develop fishermen’s skills and experiences and providing them with the latest fishing methods at low prices. (6) Suggesting alternative training programs for employing fishermen during fishing ban periods and providing them with necessary subsidies through the Fishermen Cooperative Union. (7) Facilitating the processes of obtaining loans provided for fish production activities. (8) The need to expand fish farming due to its importance in closing the food gap of fish.
