Embodiment 1

[0018] A kind of cultivation method of high-health Penaeus vannamei seedlings of the present invention comprises the following steps:

[0019] The invention first constructs a greenhouse for Penaeus vannamei seedlings; constructs an earthen pond with an area of ​​about 200-300 m2 and a depth of 1 m, on which bamboo or steel is used to build a greenhouse frame and covered with a plastic film.

[0020] A farmer in Gaoyou, Yangzhou raises Penaeus vannamei, and the greenhouse area of ​​Penaeus vannamei seedlings is 200m 2 , the water depth is 40cm. The seedling density is 1000 tails / square meter. One day before seedling release, 250 g of Sanbao Gaowen VC was sprinkled in the pond, and Sanbao Gaowen VC was produced by Guangdong Huizhou Sanbao Biochemical Technology Co., Ltd. After the seedlings are thrown, the bottom aerator should be turned on, and the aeration should be continued, and the dissolved oxygen should be above 5mg / L.

[0021] After the seedlings are thrown, the "wea...

[0027] A kind of cultivation method of high-health Penaeus vannamei seedlings of the present invention comprises the following steps:

[0028] A farmer in Sanduo Town, Gaoyou City, Yangzhou raised Penaeus vannamei in a greenhouse with an area of ​​250m2 and a water depth of 40cm. The seedling density is 1200 tails / square meter. One day before seedling release, 250 g of Sanbao Gaowen VC was sprinkled in the pond, and Sanbao Gaowen VC was produced by Guangdong Huizhou Sanbao Biochemical Technology Co., Ltd. After the seedlings are thrown, the bottom aerator should be turned on, and the aeration should be continued, and the dissolved oxygen should be above 5mg / L. After the seedlings are thrown, the "weaning feed" should be fed at a rate of 10 g / 10,000 seedlings for 5 days. The "weaning feed" is made of Penaeus vannamei 0#, and the feed of Penaeus vannamei 0# is produced by Rongchuan Feed Co., Ltd. of Guangdong Haid Group. The 0# material is crushed and added with aminovitamin,...

[0033] A kind of cultivation method of high-health Penaeus vannamei seedlings of the present invention comprises the following steps:

[0034] A farmer in Sanduo Town, Gaoyou City, Yangzhou raised Penaeus vannamei in a greenhouse with an area of ​​300m2 and a water depth of 40cm. The seedling density is 1500 tails / square meter. One day before seedling release, 250 g of Sanbao Gaowen VC was sprinkled in the pond, and Sanbao Gaowen VC was produced by Guangdong Huizhou Sanbao Biochemical Technology Co., Ltd. After the seedlings are thrown, the bottom aerator should be turned on, and the aeration should be continued, and the dissolved oxygen should be above 5mg / L. After the seedlings are thrown, the "weaning feed" should be fed at a rate of 10 g / 10,000 seedlings for 5 days. "Weaning feed" consists of Penaeus vannamei 0# feed, Penaeus vannamei 0# feed is produced by Guangdong Haid Group Rongchuan Feed Co., Ltd., vannamei 0# feed is crushed and added with aminovitamin, which is su...

Abstract

The invention relates to a method for cultivating highly-healthy young penaeus vannamei. The method is characterized by comprising the following steps of: establishing a young penaeus vannamei cultivating shed; preparing a cultivating feed: smashing a penaeus vannamei 0# material, and adding compound vitamin & amino acid soluble powder; stocking young penaeus vannamei: before stocking young penaeus vannamei, scattering Sanbao high-stability VC (Vitamin C) into a pond; stocking young penaeus vannamei at the density of 1,000-1,500 young penaeus vannamei per square meter; after stocking young penaeus vannamei, starting a bottom layer automatic aerator, and feeding the cultivating feed; gradually adding water in a shed cultivating period according to the conventional feeding cultivating period, adding Sanbao high-stability VC and rhodop seudanonas palustris every three days, and scattering EM (Effective Microorganisms); disinfecting: disinfecting with Sanbao organic iodine once every week in a young penaeus vannamei cultivating period; and cultivating young penaeus vannamei for 25-30 days till the young penaeus vannamei grow to 8-9 centimeters, wherein the survival rate of young penaeus vannamei is 70-85 percent. Due to the adoption of the method, the survival rate of young penaeus vannamei can be increased, and the cultivated young penaeus vannamei are larger than ordinary young penaeus vannamei.

Description

technical field [0001] The invention relates to a method for cultivating shrimp seedlings, in particular to a method for cultivating highly healthy Penaeus vannamei seedlings, belonging to the technical field of aquaculture. Background technique [0002] Vannamei Penaeus vannamei ( Penaeus vannamei ) scientific name Penaeus vannamei, is a wide-temperature and wide-halt tropical shrimp, belonging to Arthropoda, Crustacea, Decapod, and Swimming suborder. It is native to the waters of the Pacific coast of South America and is one of the three world-recognized excellent shrimp species. .
