Cultivation method suitable for farming breeding shrimps in saline-alkaline soil

Abstract

The invention discloses a cultivation method suitable for farming breeding shrimps in saline-alkaline soil. The cultivation method comprises the steps of (1) introducing basic populations; (2) screening the basic populations; (3) reinforcing shrimps; (4) establishing a family; (5) carrying out standard breeding of young shrimps; (6) carrying out independent cultivation of families; (7) testing thefamilies; (8) determining a target family; (9) carrying out hybridization test; and (10) carrying out breed preservation. The cultivation method of the invention is standard and has the advantages ofsuitability for the special ecological system of saline-alkaline soil, stable yield, and high recapture rate.

Description

technical field [0001] The invention relates to a method for breeding prawns, in particular to a method for cultivating prawn seedlings suitable for aquaculture in saline-alkali land, and belongs to the technical field of prawn breeding methods. Background technique [0002] China is a big country in Penaeus vannamei farming. It has become an important species of Penaeus vannamei in 1999. It has developed rapidly in the three southern provinces and has become the most popular shrimp species in the country. Serious problems such as uneven quality of seedlings, carrying viruses, and slow growth directly threaten the sustainable development of China's vannamei aquaculture industry; The rate dropped sharply, and the total output dropped rapidly from 1.2 to 1.5 million tons in 2012 to more than 500,000 tons in 2017, and recovered to more than 600,000 tons in 2018. Since 2010, they have been reported to Hunan, Hubei, Sichuan, Henan, and Heze, Shandong. Penaeus vannamei has been s...

Problems solved by technology

[0002] China is a big country in Penaeus vannamei farming. It has become an important species of Penaeus vannamei in 1999. It has developed rapidly in the three southern provinces and has become the most popular shrimp species in the country. Serious problems such as uneven quality of seedlings, carrying viruses, and slow growth directly threaten the sustainable development of China's vannamei aquaculture industry; The rate dropped sharply, and the total output dropped rapidly from 1.2 to 1.5 million tons in 2012 to more than 500,000 tons in 2017, and recovered to more than 600,000 tons in 2018. Since 2010, they have been reported to Hunan, Hubei, Sichuan, Henan, and Heze, Shandong. Penaeus vannamei has been successfully cultivated in inland areas such as Boxing, Binzhou, etc., but due to the cultivation methods, the cultivation area has not been expanded rapidly; the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in China, which is far larger than the national total. The area of ​​mariculture ponds is 130,000 hectares; if a culture model suitable for the special ecosystem of saline-alkali land can be found and a new strain suitable for aquaculture in saline-alkali land can be selected, it will be of great significance to increase the total output of Litopenaeus vannamei and provide high-quality protein for Chinese people; But at present, regardless of the imported SIS, Zhengda, Primo, etc., or the domestic self-selected "Zhongke No. 1", "Zhongxing No. 1", "Kehai No. 1", "Hixenong No. 2", etc. etc., none of them are cultivated for special saline-alkali ecosystems; the survival rate and growth speed of these excellent varieties in saline-alkali soil are relatively different, but they are not well adapted to saline-alkali land.
