Pond production of Artemia in Pakistan

Currently our government and the private sectors are very much interested in the establishment of marine aquaculture. For the successful operation in aquaculture of finfishes and shellfishes, the basic requirement is the suitable diet, apart from proper environment. For the larvae, juveniles and adult stages of the culturing organisms the live Artemia is the ideal food. The aquaculturists the worldover are using live food for their culturing organisms, as the live food played an important role in the dietary management of aquaculture of finfishes and shellfishes (Sorgeloos and Kulasekarapandian, 1984), particularly during larval stages. The live nauplii of Artemia are used in aquaculture of finfishes and shellfishes due to being nutritionally balanced, non polluting, economically bearable, viable and readily acceptable to the culturing species. The adult Artemia is also used for feeding the aquarium fishes particularly so when there is a clear abundance of this resource which is cheaper and can economically compete with alternative artificial diet. By the use of Artemia the aquaculturists may obtain optimum growth and survival rate of the organisms. The life cycle of Artemia is very short, which is completed within two weeks especially during dry season in highly saline waters, the two weeks old Artemia starts producing cysts. These cysts become ready to harvest within a week.
