A plan in Egypt aims to develop natural fisheries and increase fish stocks by increasing the production of grass carp fry in the Nile River. The San Al Hajar fish hatchery has thrown 100 thousand grass carp fry into the Nile River as part of this plan. The development of Egypt's lakes is also part of the plan, which is expected to increase fish productivity, provide job opportunities for fishermen, and contribute to food security. The San Al Hajar hatchery produces various types of fish and covers an area of 77 acres with a water surface area of 36 acres.
