Problems solved by technology

After irradiating prawn nauplii with a frequency of 20kHz ultrasonic wave, Wang Qingchi et al. found that the metamorphosis time of prawn nauplius was significantly shortened, and the metamorphosis rate was significantly increased, and the best time for each irradiation was 5 minutes; little research

Embodiment 1

[0033] In July 2016, in order to verify the beneficial effects of the present invention, the company personnel conducted relevant verification experiments at the lobster breeding base in Xuyi County, Jiangsu Province, and measured the yield and quality of crayfish after harvest. The results are shown in Tables 2, 3 and 4. The specific method is as follows:

[0034] 1. Shrimp seed cultivation, ultrasonic treatment and growth-promoting liquid treatment: Crayfish seedlings were cultivated in July-August 2016: juvenile crayfish with a size of 0.8-1.2cm were put into an area of ​​15m 2 120 juvenile shrimps are stocked per square meter in the shrimp seedling cultivation pond, and the water depth of the cultivation pond is kept at 0.5m; the growth-promoting liquid of shrimp seedlings is injected at the same time, and the dosage of the growth-promoting liquid of shrimp seedlings is 2.5L / m 3 The preparation method of shrimp growth-promoting liquid is: take 3.5 parts of rhubarb, 4 parts...

Embodiment 2

[0041] In July 2016, in order to verify the beneficial effects of ultrasonic treatment and shrimp seedling growth-promoting liquid, researchers conducted relevant comparative experiments in the laboratory. The results obtained are shown in Table 1. The specific experimental methods are as follows:

[0042] The present invention: adopt the method step in the step 1 of embodiment 1, cultivate 160 juvenile crayfish seedlings, count the survival rate, feed coefficient and the robustness of the shrimp seedlings after two weeks, the obtained results are shown in Table 1.

[0043] Control: 160 juvenile crayfish juveniles were cultured by conventional methods, and the survival rate, feed coefficient and robustness of the juvenile shrimp were counted after two weeks. The results are shown in Table 1.

[0044]

[0045] As can be seen from Table 1, the survival rate of the juvenile shrimp seedlings processed by the route of the present invention is greatly improved, and the feed index ...

Embodiment 3

[0047] In order to verify the effect of basal fertilizer application in the invented route, researchers adopted the method steps in Example 1 to breed 66m 2 For crayfish, yield and quality were measured after harvest; the results are shown in Tables 2, 3, and 4.

Abstract

The invention discloses an ecological and stereoscopic interaction cultivation method for high-quality crayfish. The method comprises the following steps of 1, conducting breeding of young crayfish and treatment through ultrasonic waves and growth promotion liquid; 2, selecting a site for building a pond and modifying culture water; 3, planting water plants, water arums and other aquatic plants; 4, disinfecting and stocking the young crayfish; 5, feeding the crayfish with feed and making a management scheme; 6, harvesting. According to the method, the ultrasonic waves and the young crayfish growth promotion liquid are adopted for conducting double treatment on juvenile crayfish, the development period of the crayfish is shortened, and the disease resistance of the crayfish is improved; byapplying base fertilizer, the nutrients of water and soil are increased, the growth and development of aquatic organisms are facilitated, and sufficient vegetable feed is provided for the crayfish; byfeeding the crayfish with feed suitable for different growth periods of the crayfish, the dosage of the feed is reduced, and the quality of the fed crayfish is higher. The allelopathic effects of theaquatic arums of purifying water and conducting sterilizing and disinfecting are utilized, thus the water environment is improved, and the probability that bacteria are bred and the crayfish are infected is reduced.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an ecological three-dimensional interactive cultivation method for high-quality crayfish. Background technique [0002] Crayfish (Procambarus clarkii), whose scientific name is Procambarus clarkii, belongs to the aquatic animal of Procambarus clarkii in biological classification. Crayfish is an exotic species, native to the southern United States and northern Mexico. It was introduced from Japan to the Nanjing area of ​​China in the 1930s, and then gradually expanded to all parts of the country due to natural transmission and artificial breeding. Its main production areas are Hubei, Jiangsu, Anhui, etc. the middle and lower reaches of the Yangtze River. Crayfish has now become a species in China's natural water bodies, and in some areas it has even formed a dominant population. In terms of geographical distribution, crayfish mostly inhabit freshwater waters such as lakes, ponds, rive...
