Fresh water aquaculture method for penaeus vannamei

Abstract

The invention discloses a fresh water aquaculture method for penaeus vannamei. The fresh water aquaculture method comprises the following steps of: preparing a penaeus vannamei pond; desalting penaeus vannamei larvae; improving the immunity of the penaeus vannamei by using Chinese herbal medicines; regulating and controlling the water quality; biologically preventing and controlling; and daily managing and harvesting the penaeus vannamei. The fresh water aquaculture method is characterized by comprising the following steps of: artificially enclosing colored cloth at corners of a fish pond to form a desalination box; artificially configuring chemical raw materials into sea water in the desalination box and gradually desalting the sea water to form fresh water; enabling the penaeus vannameilarvae to gradually adapt to the growth in the fresh water; carrying out health care in the growth process by adopting the Chinese herbal medicines researched by Zhongshan University; and controllingthe water body by using a clarias leather or grass carp to prevent pests from being spread. Under the condition of sufficient feed, the penaeus vannamei can quickly and healthily grow. The fresh water aquaculture method is simple, easy in operation and convenient in popularization and application; according to the breeding demonstration of 68 popularizing demonstration sites with 2000mu in Li county of Hunan Province, 400-600 kilos of penaeus vannamei are produced in each mu, the production value is 12800-19200yuan, the profit is 8000-12000yuan of each mu and the cultivation success rate reaches 100 percent; and the fresh water aquaculture method is deeply favored by local farmers.
