Dragonfly is a primitive wild fish, which can be cultivated artificially. Artificial seedling raising and adult fish culture in Shenzhen, Guangdong Province have been successful one after another. According to reports, the artificial breeding of Dragon Wings grows fast, and the cement pond is used for industrial breeding. Fish with a weight of 22g and a body length of1.2cm are stocked. After 360 days of culture, the average weight of each fish increased to 65438 0.830 g, and the absolute weight gain was 65438 0.808 g. In the cultured marine fish species, this growth rate is extremely rapid. According to the feeding experiment, after 1 year feeding, each tail can reach 1.5kg ~ 2kg, and 12.5kg ~ 15kg in the next year. In that year, the smallest individual was 750g, and the largest individual was 2,500g. The weight of 70% fish was between1500g ~ 2,000g, and the specifications were relatively neat. Therefore, the economic benefit of dragon fin culture is considerable. Therefore, all localities can actively study and develop arowana culture according to market demand and resource conditions.
