| Abstract | ||||
| The study aimed to identify the current situation of fish production in North Sinai Governorate, with a focus on fish production in Bardawil Lake, as it is the most important source of fish production in the governorate, As well as measuring the development and impact of environmental factors on fish production in that lake, with the aim of developing recommendations that help avoid some of the problems facing production, which were referred to in the research problem. The results showed that the annual catch of fish in North Sinai Governorate amounted to about 6.17 thousand ton during the period (2000-2010), and then decreased to about 4.59 thousand ton during the period (2011-2021). In general, the annual average of the amount of fish caught was about 5,38 thousand ton during the period (2000-2021). By studying the effect of environmental factors on the fishing units deployed in Lake Bardawil and working in the al-Dabba and al-Bos crafts, the results indicated that the most important factors affecting the productivity of the fishing units operating in the al-Dabba craft using Step wise Regression Analysis It is the decrease in the area of the lake, the decrease in the amount of food in the water (plant and animal plankton), and the decrease in the water temperature. By examining the impact of environmental factors on the productivity of fishing units operating in the linen craft, it was found that they are represented in the high level of salinity of the lake water, and the lack of purification of the lake’s spurs, each of which leads to a decrease in fish production by an amount of about 2.24, 1.35 ton / year from the average. The year for each of them, respectively, and through the findings of the research. Conclusively, it is recommended to develop a timetable for clearing the Boaghiz and dredging the lake on an ongoing basis, and to provide financial resources for these operations. | ||||
