The significance of the study lies in the fact that governmental fish farming and the establishment of governmental fish farms will bring about economic, environmental and social benefits that will contribute to the development of unexploited areas and the peripheral districts of the governorates and transform them into ecologically rich areas.The present research aims at identifying the development of government fish farms in Egypt, drawing a modern realistic map of the geographical distribution of governmental fish farms, and determining their production and resources with application to the Barseeq government fish farm at Abu Homs, Beheira Governorate. It also aims at identifying the factors affecting the settlement of Barseeq fish farm and its feed factory. Finally, the present research aims at identifying the administrative, technical, productive, financial, and marketing problems facing governmental fish farms and trying to find some appropriate solutions to them.The study came up with some findings, the most important of which is that governmental fish farms have increased in number, area, and quantity of fish of various types. They also have great capabilities and resources, large areas that can be exploited, and feed factories whose production is characterized by high quality and reasonable prices. Finally, the study recommended some solutions to the problems facing governmental fish farms in terms of production, marketing and administrative aspects.

Qualitative assessment by macro-invertebrates is known as a suitable method to determine the health of the river. In this study, the diversity and abundance of Baliqlu River macro-invertebrates were evaluated from June 2019 to May 2021. SamplingsSamples were taken by Surber sampler during four seasons and physico-chemical parameters such as TEM, DO, pH, BOD, and some heavy metals (Cd and Pb) were measured. Diversity indices (Shannon-Wiener), and biotic indices (EPT, HFBI, and BMWP) were calculated in four stations. A total of 8328 macro-invertebrates from the Diptera, Ephemeroptera, and Isopoda were identified. The highest frequency percentage of the dominant groups was related to the Caenidaed, Chironomidae, and Simuliidae. The results of heavy metal accumulation in two classes showed more cadmium and lead accumulation in the Clitellata class (suborder Hirudinea) than the Insecta class (Caenidae family). The results of conventional comparative analysis (CCA) demonstrate that the distribution of most macro-invertebrate families is influenced by the DO parameter. According to the HFBI, the water quality decreased from upstream to downstream in all seasons, and the level of pollution was higher in station 5 compared to other stations, due to human activities, cattle crossing, and sewage output of fish farms.

This study investigated fish production in Egypt. Under Fish Macroeconomics in Egypt, fish production has expanded to about 418,600 tonnes in 2020 from natural fisheries. But fish farming reached 1.59 million tonnes in 2020 (compared to 1.64 million tonnes in 2019, decreasing by 3%). Based on the fish microeconomics production function in fish farming, the independent variables can be arranged according to the relative importance of their impact on the fish mixture (mullet and tilapia). The variable feed quantity occupies the first place, followed by organic fertilisation, the number of fingerlings, the number of employees, the duration of the production cycle, the amount of oil and fuel, and finally the farm manager's experience. Based on the cost structure, fixed and variable expenses made up 13.2% and 86.8% of total operating costs, respectively. Based on the fish microeconomics profitability function, the findings revealed how successfully tilapia and mullet fish were produced per acre in sample farms in Fayoum Governorate: The ratio of total revenues to total expenses was roughly 1.9. The quantitative break-even threshold was 0.34, which means the production process is in the farm owners' interest. Therefore, fish farm profitability analysis is favourable. Encourage farm owners to maintain and grow production initiatives and handle producer difficulties.

This research aimed to identify the general characteristics of the respondents, the possibilities available in fish farms, the sources of information for fish farmers, the extension services provided by the General Authority for Fish Resources Development to fish farmers, and the farmers’ opinions on the quality of the extension service provided by the General Authority for Fish Resources Development for fish farmers. And determining the factors related to the farmers’ opinions on the quality of the extension service provided by the General Authority for Fisheries Development to fish farmers, the problems that impede achieving quality in the extension service in the field of fish farming, and the respondents’ suggestions to address the problems that impede achieving quality in the extension service in the field of fish farming, and this study was conducted in Damietta Governorate, and the total number of private fish farms in Damietta Governorate was calculated and found to be 1518 private farms. The sample was taken at a rate of 10% of the total number of private fish farms. Consequently, the sample size became 152 farms. The sample was distributed to centers according to the relative weight of each 57 respondents from Shata region, and 45 respondents. From the area of Sheikh Durgham and Ezbet Al-Burj, 28respondents from the Al-Ratma area and Shatt Jeriba, and 12 respondents from the area from the Al-Siyala, AlAnania, and Al-Basarta areas, and 11 respondents from the graduate youth area in Shata. The most important results were: It turned out that 20% of the farms had small capabilities, 47.4% of the farms had medium capabilities, and 32.2% of the farms had large capabilities, and it turned out that (29.6%) of the respondents were exposed to sources Information is low, (31.6%) of the respondents have medium exposure to information sources, while (%38.8) have high exposure, and it turns out that (14.5%) of the respondents indicated that the level of extension services provided by the General Authority for Fish Resources Development to fish farmers is low, While (61.8%) of them indicated that the level of service is medium, while (23.7%) of them indicated that the level of service is high, and it turned out that (16.5%) of the respondents indicated that the level of quality of the actual agricultural extension service is low, while (21.7) indicated that the level of quality of the actual agricultural extension service is low. %) of them indicated that the level of service is low, while (61.8%) of them indicated that the level of service is high,The results also showed that the most important problems that impede achieving quality in the extension service in the field of fish farming were arranged in descending order according to the arithmetic mean as follows: the high fuel prices, the instability of selling prices with an average of (2.8 degrees), then the high transportation costs with an average of (2.6 degrees), then both the increase in mortality during transportation, and the lack of basic environment and public services with an average of (2.5 degrees), then the lack of good fodder, and the weakness of extension services with an average of (2.4 degrees), then the difficulty of obtaining seed with an average of (2.3 degrees), and the results showed The most important suggestions of the respondents to confront the problems that impede achieving quality in the extension service in the field of fish farming are, respectively: reducing or subsidizing fuel prices by 96.71%, then emphasizing the legislation to protect water from pollution by 93.42%, then expanding lending in the field of fish production At a reduced interest, to encourage investment in fish farming at a rate of 92.76%, then provide subsidized feed at a rate of 91.45%, then provide good seed at reasonable prices at a rate of 90.79%, and then prepare training courses to raise the efficiency of producers, workers and extension workers in Fish traveled by 71.71%, then encouraged the establishment of cooperative societies to provide farmers with production requirements such as feed at reasonable prices, at a rate of 63.82%.

The study aimed to estimate marketing margins and marketing costs, as well as the prevalence of consumer pounds as measures of marketing efficiency, according to the available marketing channels and fish varieties, to assess the current situation of marketing fish produced from government fish farms in Sharkia Governorate, in addition to the farm budget analysis model for the production stage, through preliminary data. For a field sample representing the different marketing channels, as well as the published and unpublished secondary data of the Public Authority for Fish Resources Development. It was found that the sample farms represented 60% of the number of government farms in the governorate, 48.5 % of its area, and 97.58% of the production volume. The marketing channel is followed from the producer to the wholesaler and then to the retailer, where the production of government fish farms is marketed to wholesalers through an auction in which the price is determined according to the variety and the size within the variety. The wholesaler packs and weighs the fish in plastic containers of different capacities and transports them in refrigerator cars to the wholesale markets in Cairo, Suez and Kafr El-Sheikh, in addition to retailers in the governorate. The study found that government fish farms achieved a positive net profit of 8.74 thousand pounds per ton, and average revenues of about 26.10 thousand pounds per ton, and the average productivity of an acre was 3.83 tons. It was also found that the marketing margins for the wholesale and retail phases were high compared to the costs of the marketing functions represented in sorting and grading, packaging, transportation, preservation and commissions.

The study dealt with the role of crustaceans and aquatic organisms and their importance in achieving food security. Crustaceans and aquatic organisms, whether produced from cultivation and breeding or from natural fisheries, marine, and river, constitute an important and major source of protein and basic and health-enhancing nutrients, by providing food. For man, and the extent its contribution to the economy of North Korea, and production is affected by several natural, human, political and economic factors. The methods and methods of fishing and aquaculture in Southeast Asian countries have developed greatly, after they were primitive methods that have become dependent on technological methods. This has led to an increase in fish production. It also pays great attention to marine fishing and crustacean farming to increase production. Several industries depend on crustaceans such as drying, salting, smoking, freezing, and packing, in the midst of political and economic crises and emerging diseases (COVID-19).

The research aimed at evaluating some types of integrated fish farming in desert lands represented by the monosex tilapia culture systems in ponds lined with plastic and built with bricks, cement and concrete for an area of 500, 600, 750 m2 and for a culture period of 7 months, the study relied on two sources of data, the first of which is secondary data from the General Authority for Fish Resources development, and it relied on primary data from field visits to models of integrated fish farming from Minya Governorate, has a total of 21 views. By studying the trend of total fish production and fish farming according to production sources, it was found that the fish production from governmental and private farms increased at a statistically significant annual change rate of about 5.1 and 7.7 thousand tons, respectively. The study shows that the fixed costs of monosex tilapia culture for ponds lined with plastic and built of bricks, cement and concrete and used as a water tank in the desert land amounted to about 200, 700, 300 pounds, representing about 0.4%, 2.3%, 0.9% of the total costs amounting to about 44.95, 30, 32.34 thousand pounds, and the variable costs amounted to about 44.75, 29.3, 32.04 thousand pounds, representing about 99.6%, 97.7%, 99.2% of the value of the total costs, respectively. The two standards of price and quantity break-even to cover the variable costs of monosex tilapia culture activity in plastic-lined ponds, built with bricks, cement, and concrete for an area of 500, 600, 750m 2 and used as water tanks in desert lands show that these activities are more bearing the price risk and the production risk. The price-to-quantity break-even ratio to cover the changing costs of the aquaculture pattern for tilapia production in plastic-lined, brick, cement, and concrete ponds indicates the bearing of the risk resulting from low price and production quantity and this can be used by encouraging small-scale producers to produce tilapia in plastic-lined ponds, built with bricks, cement, and concrete.

The research aims to identify the challenges of fish farming and its role in achieving self-sufficiency in fish in Egypt during the period (2000-2018). The necessary to ensure the correctness of the obtained results from a statistical and logical point of view, dummy variables, a distribution test for independent samples, and the growth equation, in addition to some economic indicators related to the study. The study reached several results, the most important of which are: (1) The economic efficiency of fish production, plant production, animal production and insect production was estimated at about 1173.78, 570.70, 68.40, 700 in the same order during the period under study, due to the low production costs of fish production in Egypt, which amount to about 2.22% of the total production costs of the agricultural sector during that period, in addition to the rapid turnover of capital invested in the field of fish farming compared to other agricultural fields. (2) Freshwater fish contribute about 83.10% of the total fish production in Egypt during the period (2010-2019), and this percentage is distributed among the fish of those waters, represented by tilapia, catfish, carp, white and crust bead as well as the following are 67.31%, 0.83%, 14.88%, 0.04% and 0.0002% in the same order. As for the fish that are farmed in mixed waters and represented by the mullet family, they contribute about 12.20% of the total fish production farmed in Egypt during that period, while the fish that are farmed In salt water, it contributes about 4.74% of the total fish production farmed in Egypt during that period, and this percentage is distributed among the fish of those waters, represented in each of the bass, the lot, the bream, the Hanshan, the gar, the shrimp and the Shargoush as follows: 1.63%, 1.18%, 1.79%, 0.0003%, 0.00002%, 0.13% and 0.0002% in the same order. (3) Private farms occupy the first place in the production of farmed fish with an estimated rate of about 80.56% of the total fish production farmed in Egypt during that period. Fresh water fish represented about 81.90%, then mixed water fish by 12.30% and saltwater fish by 5.80%, then comes in the second place is the culture in floating cages, which represents about 16.43% of the total fish production farmed in Egypt during that period. Freshwater fish are represented by about 86.50%, then mixed water fish by 13.30% and saltwater fish by 0.2%. The third place comes from culture in Rice fields with a percentage of about 1.91% of the total fish production farmed in Egypt during that period, followed by government farms, intensive aquaculture and semiintensive aquaculture, where each of them amounted to about 0.89%, 0.14%, and 0.06% in the same order. (4) It was found that each of the variable average price per ton of farmed fish in thousands of pounds and the number of fresh water fry and fingerlings produced in private hatcheries in million units have a positive impact on the amount of production of farmed fish, and to estimate the relative importance of these variables in their impact on the amount of production of farmed fish, as it was found that the variable average price per ton of fish farmed in thousands of pounds occupies the first place in its impact on the amount of production, followed by the variable number of fresh water fry and fingerlings produced in private hatcheries in million units, where the standard partial regression coefficient for each is estimated at about 0.959, 0.240 on straight. (5) It was found that the average percentage of fish farming’s contribution to the fish self-sufficiency rate during the period under study was about 53.83%, with a standard deviation of about 11.62%. The time period is about 66.99%, with an average relative change rate of about 26.69%, with an annual growth rate of about 3.90%. (6) The most important challenges of fish farming in Egypt are: the multiplicity of administrative bodies supervising the fisheries sector, the absence of a law regulating work in the field of fish farming, the misuse of water resources in Egypt, the difficulty of applying the biosafety system to Egyptian fish farms, and the low productivity Fries and the high percentage of wastage of them in all stages of circulation between collection and unloading centers and culture sites, and the lack of fish feed is one of the most important challenges of fish farming, as farms depend on agricultural residues and grain feed, which requires the expansion of their production locally. The study reached some recommendations, the most important of which are: (1) Establishing a unified administrative body that works to facilitate the legal procedures for the investment process in the fish farming sector and the issuance of approvals and permits to increase the attraction of investors to this sector. (2) The development of a specific, integrated, and articulated law regulating work in the field of fish farming that guarantees coordination between all relevant authorities in this field and includes clear explanations for all matters related to fish farming. (3) Optimum utilization of water resources used in the field of fish farming in Egypt. (4) The necessity of applying quaponics systems on a large scale in fish farms, which is one of the modern breeding systems for integrated closed fish farming between plants and fish. (5) Implementation of the bio-security system for fish farms, with the development of incentive policies for this purpose. (6) The need to increase the role of fish extension in the field of fish farming of all kinds through the need to pay attention to the establishment of extension fish farms that are responsible for the wide application of laboratory experiments in the areas of nutrition and fish diseases in preparation for their actual application on fish farms if their productive feasibility and contribution to increasing fish production are proven.

The development of fish production is one of the pillars of the development of animal protein sources in Egypt. The Egyptian fish production increased from 1.9 million tons in 2018 to 2 million tons in 2019, with an increase reached 5.4%. This is due to the increase in the amount of fish farms production, which comes their production as a first rank with a rate of 79.7%, followed by lakes with percentage 10.8%, then marine waters with 4.9%, fresh water with 3.8%, and rice fields with 0.8% of the total amount of fish production in Egypt1 Lake Qarun is characterized by the diversity of its production of fish, up to ten species, but this production stopped due to many factors, the most significant of which is the increase in salinity and the accompanying environmental changes such as a decrease in biological diversity and a decrease in fish production, besides the continuation of pollutants flowing through the drains, whether sewage or transfer of some species of harmful jellyfish to the lake, the characteristics of the lake have deteriorated significantly1 The results show that the development of fish production in Egypt over the period (2003-2019), it was found that marine fisheries contributed 9.32% of the total fish production in Egypt, with an average quantity of about 114.29 thousand tons, while lakes contributed 13.82% of the total fish production in Egypt. The total fish production in Egypt with an average quantity 173.81 thousand tons, while fresh water contributed by 6.99 percent. It was also found that fish farming occupies the first place in terms of contributing to fish production in Egypt, with an average production amount reached 967.38 thousand tons, representing about 69.86 %. By studying the seasonal fluctuations of the fishing from Lake Qarun, the results showed that the fish species in Lake Qarun were characterized by seasonality during the average period (2015-2019), which is the period during the decision of stop fishing was applied for two months, namely May and June, by increasing the fishing from the general average 95 tons over the months of January, February and March, reaching 150, 122, 113 tons, respectively, where its highest limit was in January, with a seasonal index amounted 157.89%, while it reached a minimum in the months of April and December, with a seasonal index reached 38.95%, 53.68%, respectively.

This study was primarily aimed at prospective role of agricultural extension in the field of fish farming in Rashed and Edko district in Behiera Governorate. The questionnaire was used in a personal interview to update the field data from the 200 research samples from the owners of community fish farms in Rashed and Edko district. The data were collected in more than one year, and statistical methods used percentages, frequency and relative distribution tables, arithmetic means, standard deviation, simple correlation coefficient, and multiple Step Wise regression coefficient using Spss program. The most important results were as follows: - 49.5% of researchers had a low overall level of knowledge, compared with 39,5% had an average overall level of knowledge, while 11% had a high overall level of knowledge. There is no doubt that the general level of knowledge of the researchers may affect the amount of production from these farms. - The most important problems facing the researchers are the high costs of establishing a fish farm, followed by the lack of physical capacity of the farmers. The low price of fish in marketing, the lack of an independent financial source to finance the fish farming process, frequent problems with taxation, high rent prices for fish land, unclear role of extension in the development and development of fish farms for the establishment of extension farms; The absence of the vital role of the Public Authority for the Development of Fish Resources, the failure to supply extension publications to farmers; Lack of inputs, difficulty in obtaining good crops, the appearance of many diseases in fish during breeding. water scarcity and lack of availability throughout the year, lack of water for fish farming. low feed quality, high feed price, low fish harvest, and finally no intensive farming systems in farming.

In spite of the spread of integrated Aquaculture systems with plants in Egypt, the official statistics of the General Authority for Fish Resources Development have devoid of reference to the productivity of these systems even though they are among the most productive systems that can be exploited not only to benefit from increased yield, but also to use. Optimizing land and water, finding simpler methods to control pollution, improve management of productive factors, as well as high quality and increase the safety of food produced. The fish farming system in earthen ponds is still the dominant system and the most widespread in Egypt. Therefore, the research aimed at estimating the economic efficiency of integrated Aquaculture systems in Egypt. Identifying the most important problems facing integrated Aquaculture in Egypt and the most important proposed solutions. It has been shown by estimating the productive efficiency according to the concept of constant return to capacity for the closed integrated Aquaculture system that the average production efficiency has reached about 0.57, meaning that the same level of fish production can be achieved using only 57% of the actual combination. Of the inputs used in the production process, as it has been shown by estimating the production efficiency according to the concept of variable return of capacity that the average production efficiency has reached about 0.89, meaning that the same level of fish production could be achieved by using only 89% of the actual combination of inputs used in the production process. Open integration and according to the concept of constant return to capacity, the average production efficiency has reached about 0.51, meaning that the same level of fish production can be achieved using only 51% of the actual combination of inputs used in the production process, and according to the concept of variable return of capacity, the average production efficiency has reached About 0.75, meaning that the same level of fish production can be achieved by using only 75% of the actual combination of inputs used in the production process.

The capture fisheries production reached about 377 thousand tons, representing about 19.3% of the total Egyptian fish production, which amounted to about 1.8 million tons in 2018, while the production from fish farming reached about 1.5 million tons, representing about 80.7% of the total fish production. The total production from Lake Burullus in 2018 amounted to about 1.9 million tons in 2018, and the total production from Lake Burullus in 2018 amounted to about 71.4 thousand tons, and the total production of the North Delta Lakes in 2018 was about 152.6 thousand. Tons, and the total production of Egyptian lakes in 2018 was about 195,000 tons. The total production from Manzala Lake in 2001 amounted to about 68.4 thousand tons, and in 2018 reached about 65 thousand tons, with an average of about 55.9 thousand tons. The total number of boats in Manzala Lake in 2001 reached about 3.26 thousand boats, and in 2018 about 1 69 thousand boats, with an average of about 7.65 thousand boats, and with the estimation of the equation of the time direction of the boats, it was found that the best models are the linear model, where (y) represents the estimated production and (x1) represents the number of boats, and their statistically insignificance was found due to the widespread phenomenon of overfishing in the lake. The price of a ton of fish in Lake Burullus in 2001 was about 7.98 thousand pounds, and its price in 2018 was about 27.17 thousand pounds, with an average price of about 13.79 thousand pounds during the study period. Burullus shows that the best model is the linear model where (y) represents the estimated production and (x3) represents the price per ton of fish, and means that a 1% change leads to an increase in production by 0.791 thousand tons, and its significance was found statistically at the probability level of 1%. The political leadership in interested since 2014 with Environmental status specially with developing Egyptian lakes rising its efficiency and increasing its production starting firstly with lake Manzala then lake Burullus.

The research aimed mainly at identifying the most important economic factors affecting the tasks of marine farm managers in Damietta Governorate, Egypt, estimating the structure of productivity costs in marine fish farming according to farm capacities, estimating technical and economic efficiency indicators for marine fish farming according to farm capacities, and identifying the personal and social characteristics of the respondents, and the specific factors the farm and the factors related to seed, and to identify at the general level the importance and performance of tasks and the importance and performance of tasks (each task separately) tasks related to managers of marine fish farms in Damietta Governorate, and determining the difference between the general average for the degree of importance and performance of the studied tasks, and defining the differences between the mean averages for the degree of importance and performance of the tasks (each separately) tasks identifying the most important problems facing marine fish farm managers, and Sheikh Dergham, Al-Sahel and Al-Rattama, because these areas are concentrated in marine fish farms, and 90 farms were chosen, representing 10% of the total fish farms in the regions. The farms were divided into three productive capacities: small production capacities of an area (less than 14 faddan), and average production capacities of an area (from 14 to 27 faddan), and finally large production capacities of an area (greater than 27 faddan). The questionnaire was used in a personal interview to collect field data during the period from August to September of 2019, and the quantitative and descriptive method was used, and the calculation and estimation of technical and economic efficiency indicators for marine fish farming was used. Frequencies, percentages and mean, and the most important results can be summarized as follows: The average total investment costs in large-capacity farms amounted to about 8975 pound, and in small-capacity farms 4289 pound, and the least of them were in medium-capacity farms Where it reached about 3382 pound, and it was also found by comparison between the three different capacities, the quantities of farm production in order were small, then medium, and finally large capacity as follows, in order, 6870.61 kg, 17719 kg, 18111 kg. While the revenues were as follows: 426.733, 888.477, 1068 thousand pounds in succession, and from this comparison it became clear that the net profit of the farm reached its maximum for large farms to about 561.540 thousand pounds, while in medium-sized farms it reached 407.09 thousand pounds, and the lowest of them was on farms with The small capacity amounted to about 231.41 thousand pounds, and the results of the study indicate that the average farm capacity exceeded the productivity of a square meter basin, as it reached 0.316 kilograms per square meter. The square meter basin reached 7.57 pounds, and 7.27 pounds per Small and medium capacity respectively. while revenue was as follows : 426,656, 888542, 10,06868 thousand pounds, and from this comparison it became clear that the net profit of the farm reached its maximum for large farms to about 561,523 thousand pounds, while it reached in medium-capacity farms 407,16 thousand pounds, and the least of them were on small farms of about 224,349 pounds A thousand pounds.

The study focused on the development of the technical level of the use of fish resources in aquaculture in Sharkia Governorate in order to increase the efficiency of using these resources. The study relied on the method of content analysis for many recent studies based on field samples from Sharkia Governorate. As well as secondary data published from the book of fish statistics issued by the General Authority for the Development of Fisheries and secondary data not published by the Directorate of Agriculture in Sharkia, and the study showed that, despite the economic feasibility of fish farms which are indicated by all previous studies and the development of productivity and costs according to the development of intensification of production elements, but these farms are still working less efficiently, which requires increasing the efficiency of the elements of production, especially increase the farm area and the rate of loading of fry and feed and increase the production period from than the current averages. For the development of pelvic farms, especially with regard to the stability of tenure, which is one of the most important problems facing the temporary farms, which represent more than 82% of farms in the Governorate and more than 79% of the area of private farms and produce more than 92% of the total production of fish in especially as it has been shown that the use of land in fish farming yields a better return than it is used in plant farming and better soil, and increases the efficiency of the use of the unit of water as it is an activity used the water and not consumed it, in addition to some other problems such as higher input prices and higher cost especially during the period of fishing, and the high mortality rate in fish fry during transport, which amounts to about 10%, and the problem of pollution is one of the most important problems facing the fish farms as there are still farms using sewage, especially the area (Baher elbaqar), and follows that environmental and health adverse effects on the health of the consumer of fish and the producer in spite of the positive impact of the use of this water on the productivity of the area fish farm with respect to fish breeding pattern loaded with rice fields, requires re-adjust and restructure the system to avoid obstacles and achieve the desired goals.

Fish is one of the main food sources witch rich of animal protein, In addition, the fish meat represented about 80% of its live weight, While This percentage represented about 65%, 54% in poultry and cattle meat respectively, Fish production has reached about 1.1 million tons, while domestic consumption amounted to about 1.3 million tons, Average of fish consumption per capita was estimated at 14 kg per year, and the selfsufficiency rate was estimated of around 87.6% as an average for the period 1995-2011. The research problem refers to the lack of domestic production for consumption and thus face a fish gap, While Egypt enjoying the sea and the Nile River, and the expansion possibility in aquaculture, The research aims to clarify the relative importance of the Egyptian fish production from different sources And study the most important factors affecting the fish production and consumption, the research relied on quantitative descriptive analysis methods, it was used trend functions, in addition to use of multiple regression in linear and logarithmic forms, to determine the most important factors affecting the fish production and consumption. As for the data sources has been obtained from the Central Agency for Public Mobilization and Statistics, In addition to fish production statistics published by the General Authority for the Fisheries Development of Agriculture and land reclamation Ministry. Through the period of study 1995-2011 The most important results was: sea Production oscillating around the average, that means the use of the seas and Nile River in Egypt is not the best, so must expand the use of cages in aquaculture (fish farming) in all appropriate waterways, as it turns out that aquaculture is the future for fish production in Egypt, So care must be taken for the development of marine aquaculture. The research showed that the most important factors that affecting the fish production in Egypt is the number of mechanic fishing boats per unit, The number of fishermen and the amount of consumed fish consumed as an increase in each factor separately by unit. that leads to a change in fish production increase by 0.197%, 0.106%, 1.04% thousand tons respectively. While it became clear that the most important factor that affecting the fish consumption is the poultry price, the income average per capita as an increase in each factor separately by 1%, This leads to a change in the fish consumption as an increase in each factor by 0.357%, 1.78%, respectively. Recommendation The research Recommended to follow new ways of biotechnology for the production of strains of high fish production, And the expansion of new fish and shrimp species, and maximizing the role of aquaculture in fresh water and seawater.

Fish production increased in Egypt from 724.4 thousand tons in 2000 to reach 1.4 million tons in 2011, represents the most important production of animal protein, also increased the relative importance of fish farming from 47% to 72%. Which called attention to estimate the efficiency of the use of economic resources in the production of fish farms in Port Said region. The results of the study showed that technical competence and in accordance with the concept of variable earnings capacity (TEvrs) could be worth ranged between 98 % for the fourth categories and 99 % for the first category of the largest space to signify the importance of the economies of capacity. On the contrary, marked the third category of the sample farms, and is the smallest area of the first and second, achieving the highest estimate of the economic efficiency of 99 %, followed by the first and second class by 98 %, and achieved a fourth category lowest estimate of the index of economic efficiency, 92%. These percentages reflect the optimal amount of resources compared to the actual quantities used of resources used. The results of the study indicate that it must reduce the average area from 12.3 to 11 Fadden and achieve the same level of production. Can also reduce the average number of fry 169 to 161 thousand fingerlings, should also increase technical labor for the farm from 251 to 260 workers and reduce regular employment on the farm of 517 to 507 workers only, as well as reducing working hours ATMs from 558 to 509 hours of the farm, when you achieve these farms for the full economic efficiency. The study recommends the importance of efficient use of factors of production and especially fry element (fingerling), can also review the technical labor and regular working hours ATMs as an indicator of techniques applied on the farm, especially after achieving technical and economic efficiency, Also need to focus development efforts and development on the fourth farm groups, which amounted to an area of Fadden, where estimates were indications the technical and economic efficiency least among the sample of the study groups.
