Problems solved by technology

[0003] In the prior art, the original pond breeding technique is used for the shrimp fry of Penaeus vannamei, but this technology has many disadvantages: for example: the quality and survival rate of the shrimp fry are low, the size of the shrimp fry bred is small, and the coefficient of variation is large, etc. Therefore, the research The new original pond nursery technology is of great significance

Embodiment Construction

[0011] 1. Test material

[0012] Ecological nursery large pond (length: 50m, width: 20m, height: 2.5m), seawater, vannamei nauplii (SPF), rotifers, Artemia, chaetoceros, chlorella, Ekouhong, Eguchi black, Probiotics, Bishui'an, Shuibao, Lidojing, Biotin, Activation, Yeast, etc.

[0013] 2. Test steps

[0014] Nauplii is added after the Penaeus vannamei nauplii are put in, which can ensure the stability of water quality during the whole seedling raising process, and can ensure the nutritional needs in the middle and late stages, so as to ensure the quality of shrimp seedlings.

[0015] This experiment was carried out in the ecological seedling workshop of the Hainan base. A total of 4 seedling ponds (length: 50m; width: 20m; height: 2.5m) were inflated centrally with nanotubes. Before releasing the larvae, wash the pools of A1, A2, A3, and A4 according to the conventional procedures, expose them to the sun, and enter the seawater 140cm; water treasure and seawater residual ch...

Abstract

The invention belongs to the field of aquaculture, and the invention discloses a method for growing seedlings of Penaeus vannamei in primary ponds, in which dana and Artemia are added into the seedlings. In the method, a certain amount of dana and Artemia are added, and the method is used to raise seedlings, which can ensure the quality and high survival rate of shrimp seedlings, and the raised shrimp seedlings are large in size and small in coefficient of variation.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for growing seedlings of Penaeus vannamei in primary ponds. Background technique [0002] Penaeus vannamei is one of the three largest shrimp species with the highest aquaculture production in the world today. Penaeus vannamei is native to the Pacific coast of South America. Professor Zhang Weiquan of the Institute of Oceanology, Chinese Academy of Sciences first introduced this shrimp from the United States. Jiangsu, Guangdong, Guangxi, Fujian, Hainan, Zhejiang, Shandong, Hebei and other provinces or autonomous regions have gradually promoted farming. The vannamei cultured in Yangjiabo Town, Hangu District, Tianjin is world-famous, and has the title of "Hometown of Fish and Shrimp in China". Among them, the technology belonging to Penaeus vannamei is the most mature. The meat of Penaeus vannamei is delicious, and the processed meat rate can be as high ...
