Example Embodiment

[0014] The following introduces the applicant’s freshwater culture method of Penaeus vannamei in 68 households of 2000 acres in Li County, Changde City, Hunan Province from 2010 to 2011. It includes the following steps:

[0015] ①. Shrimp pond preparation: including sun pond, disinfection, clearing, water inflow and water cultivation;

[0016] ② Desalination of shrimp larvae: From June to July every year, shrimp larvae with a body length of 0.4-0.6 cm are purchased from the Penaeus vannamei breeding center, and placed in the desalination that is enclosed in a corner of the shrimp pond with colored strips. In the tank, the volume of the tank is 50-100 cubic meters, and the water depth is 0.5-1.0 meters. The tank is equipped with artificial seawater. The configuration method is to put Nacl per cubic meter of fresh water. 2 0.1-0.5 kg , H 3 BO 3 0.2-0.5 kg, MgSO 4 0.1-0.5 kg, NaBr 2： 0.01-0.1 kg, CaCl 2： 1-5 kg, KCL: 1-5 kg; 0.5-1 kg of trace elements containing iron, manganese, zi...

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.

Description

technical field [0001] The invention relates to a freshwater culture method of Penaeus vannamei and belongs to the technical field of aquaculture. Background technique [0002] Penaeus vannamei, whose scientific name is Litopenaeus vannamei, belongs to Arthropoda, Crustacea, Decapod, Penaeidae, and Penaeus. It is a wide-temperature and wide-halt tropical shrimp. Commonly known as: white limb shrimp, white prawn, the average life span can be at least more than 32 months. Adults can be up to 24cm long, with a thin carapace. The normal body color is light blue-gray, and there are no markings on the whole body. The legs are often chalky, so they are called white-legged shrimps; [0003] The meat of Penaeus vannamei is delicious, the processed meat rate can be as high as 67%, the temperature range is wide, the growth is fast, and the disease resistance is strong. It grows under the condition of ‰, and it is an excellent variety that can be cultured in desalination. Penaeus v...
