The research aims at an economic analysis of the role of each of the Egyptian sea surfaces and lakes in reducing the fish gap, one of the most important fish in Egypt.

The results obtained are statistically and logically correct.

In addition to some economic indicators related to the subject of the study.

The study reached several results, the most important of which are: (1) The average value of Egyptian fish production during the period (2000-2018) amounted to about 16.92 billion pounds, with a standard deviation of about 12.52, and the annual growth rate was about 11.70% .

(2) The average total fish production in sea fisheries during the period (2013-2018) amounted to about 105.90 thousand tons, representing about 3.70% of the total fish production in Egypt, and the average total production of lake fisheries reached about 176.40 thousand tons, representing about 10.70% .

(3) It was found that the average fish production from the Mediterranean fisheries during the period (2000-2018) amounted to about 64.84 thousand tons with a standard deviation of about 11.96, and the average production in the last five years of the study period was about 58.99 thousand tons, representing about 56% of the total sea production during the last period, and that it took a downward trend at an annual rate of about 0.50% during the study period.

(4) The average fish production from the Red Sea during the study period was about 53.09 thousand tons with a standard deviation of about 11.60 tons, and the average production in the last five years of the study period was about 46.79 thousand tons, representing about 44% of the total sea production during the last period And that it took a downward trend at an annual rate of about 2.80% during the study period.

(5) The average production of the Egyptian lakes during the study period was about 171.83 thousand tons with a standard deviation of about 13.82 thousand tons, and the average production in the last five years of the study period was about 175.84 thousand tons, representing about 10.39% of the total fish production in Egypt during the period The latter has been shown to be unstable in the Egyptian lakes production of fish between increase and decrease.

(6) The average per capita consumption of fish in Egypt during the study period was about 18.10 kg, with a standard deviation of about 2.65 kg, and the average per capita consumption of fish in Egypt during the last five years of the time series was about 21.87 kg, which indicates a trend The Egyptian consumer is increasing his consumption of fish in order to obtain animal protein and a lower price compared to other sources of animal protein, and the annual growth rate has reached about 2.60% .

(7) The average fish food gap in Egypt during the period (2000-2018) was about 229.16 thousand tons, with a standard deviation of about 64.72 thousand tons, and the annual growth rate was about 2.80% .

It was also found that the average rate of self-sufficiency in fish during the time series reached about 83.69% with a standard deviation of about 3.96% , and it took an upward trend with an annual growth rate of about 0.50% .

(8) It has been shown that the total fish production variable has an adverse effect on the amount of fish gap, while the average individual consumption and population variables have a positive impact on the amount of that food gap of fish, and it has been shown that the local fish production variable ranks first in its impact.

On the amount of that gap, followed by the average individual consumption variable, and finally the population variable, respectively.

The study recommended the need to make maximum use of the area of Egyptian sea surfaces and lakes in fish production, improve production quality, overcome all challenges and obstacles, remove all encroachments on Egyptian lakes, and raise their productive efficiency of fish in order to bridge the nutritional gap of animal protein through fish.
