This research aimed at measure the impact of some of the main determinants of fish demand in Egypt in order to change consumption patterns. The study relied on primary data collected through a specially prepared questionnaire. The sample size was 1100 Person from different governorates of Egypt. The study also relied on descriptive analysis, multiple linear regression analysis, and some other inferential analyses, and the SPSS programme was used to perform these analyses. The results showed that about 79% of Egyptian consumers eat less fish twice a week, and that 87% of consumers prefer fish from fisheries over farmed fish. The average annual consumption per capita rises with the increase in the level of income and age, while it is not affected by the educational level. It was found that the regression model is significant. And that the independent variables explain about 83% of the change in the dependent variable (fish Demand).   These variables are: the number of times fish is eaten, the amount eaten in the meal, the region, the number of family members and the preference of poultry over fish.
