Development of fish production which considers one of the essential animal protein sources becomes crucial issue. The production of fish is still insufficient to meet the consumption needs, which increases the food gap of fish. This study is to determine the levels of technical efficiency on a sample of fish farms using Data Envelopment Analysis (DEA) and to identify key production factors that differ efficiently and inefficiently. The mathematical analysis ismainly based on data obtained by means of a questionnaire applied to a random 30 fish farms in Damietta Governorate. DEA is used to generate technical efficiency scores under assumptions of both constant returns to scale(CRS) and variable returns to scale(VRS). Technical efficiency has an average of 0.94 under CRS showing a wasting in the inputs by 6%. Allocative efficiency is about 0.91 and 0.96 under CRS and VRS, respectively. Also, the results show that there is a wasting in used resources where the economic efficiency is represented about 0.85 and 0.90 under CRS and VRS, respectively. This indicates that an average of 15%-10% potential scope still exists for improving the actual marine fishery production in Damietta Governorate with the given inputs. The results indicate that it is necessary to reduce farming area, labor, and fuel by 1%,4%, and 4.09%, respectively, as compared to the current used inputs. And fingerlings of sea bream should be decreased by 14.50% but the mullet fish fingerlings need to be increased by 7% as compared to the exsiting used inputs. Main problems facing fish farmers are limited resources of feed and marketing. The study recommends improving technical efficeieny rationalising the use of resources especially the fingerling, labor, and fuel in fish production to achieve the economic efficiency, in order to eliminate the food gap of fish in Egypt.

This research aims to measure the impact of the exchange rate on foreign direct investment in Egypt during the period (2000-2022), as this period witnessed successive rises in the exchange rate of the US dollar. The theoretical Analysis expect an opposing effects and. The theoretical analysis relied on a brief survey of previous literature to study the relationship between exchange rate fluctuations and foreign direct investment flows. The research concluded that despite of the successive depreciation of the local currency, foreign direct investment flows in Egypt, which were characterized by fluctuation during the study period, were not affected by the relative decline in the valuation of local assets in foreign currency due to the high exchange rate. The data were estimated based on the ARCH model, an AutoRegressive Conditional Heteroskedasticity. The results confirmed that the exchange rate was not significant in influencing foreign direct investment flows, and the Granger ‫مصر‬ ‫فى‬ ‫المباشر‬ ‫األجنبي‬ ‫االستثمار‬ ‫على‬ ‫الصرف‬ ‫سعر‬ ‫أثر‬ ‫توفيق‬ ‫رمضان‬ ‫عبداهلل‬ ‫د/‬ ‫ػشش‬ ‫اٌشاثغ‬ ‫اٌّغٍذ‬ ‫اٌضبٌش‬ ‫اٌؼذد‬-ٛ١ٌٛ٠ 0202 022 causality test confirmed that there was no causal relationship between the exchange rate and foreign direct investment flows.
