In recent years, the rapid development of natural cages, it has no bait, labor-saving, time-saving, small investment, high efficiency, welcomed by the majority of the masses in the reservoir area. At present, Nanyang City has developed more than 40,000 cases of natural cages, ranging from fish production to adult fish farming.
