Despite the flourishing fish production in Egypt, only 17 species remain as of 1995 out of 47 species in 1948. [16] The Nile perch is one of the more prominent fish species in the Egyptian Nile. It is found in Lake Nasser and in Lake Mariout in the Nile Delta. Other fish found in the delta include the striped mullet and soles.
As a result, Egyptians have less land to farm, however, produce more crops per person than Thailand or the Philippines. The management of the Nile is important for economic growth in Egypt. [1] As a result, the effect has been that of an economic issue between various agents, both human and nonhuman agents.
GESIT fish are genetically engineered to hatch eggs that will produce 98% - 100% male tilapia. Monosex culture (all male) is more productive and will benefit the farmers. Now, around 14 strains of ikan nila have been developed by contributions from research institutes including MCFAD. Egypt 967,301 Brazil 550,050
Most of Egypt does not receive much rain, thus all of its agricultural production is around the Nile River. The population of Egypt is increasing, therefore the country will require more food and water. [16] [17] [18] Agriculture is important to the Egyptian economy, making up 11.3% of the GDP and providing 28% of jobs. [19]
Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
The aquaculture or farming of piscivorous fish, like salmon, does not help the problem because they need to eat products from other fish, such as fish meal and fish oil. Studies have shown that salmon farming has major negative impacts on wild salmon, as well as the forage fish that need to be caught to feed them.
The environmental impact of fishing includes issues such as the availability of fish, overfishing, fisheries, and fisheries management; as well as the impact of industrial fishing on other elements of the environment, such as bycatch. These issues are part of marine conservation, and are addressed in fisheries science programs.
The water in Egypt has also been found to contain heavy metal contaminants which can be harmful to health. [29] Lower Egypt releases the most waste into the Nile, it being the most populous, industrial and agricultural country in the basin. Rivers in the upper Egypt area are thought to have reduced fish varieties, phytoplankton and microorganisms.
