Embodiment 1

[0036] A low-salinity cultivation method of Penaeus vannamei, the low-salinity cultivation method of Penaeus vannamei comprises the following steps:

[0037] a) Breeding pond treatment: the breeding pond has an area of ​​5 mu, an aspect ratio of 3:1, and a sandy mud bottom. Before entering the water, sterilize the breeding pond with 100kg / mu of quicklime; Water, enter the water twice, first enter the water until the water level reaches 40 cm, add bait to the breeding pond, and then enter the water again to the water level of 80 cm; set a filter at the water inlet when entering the water, and the filter is made of 50-mesh nylon thread Straight mesh with a net length of 3 meters; the bait is water earthworms, shrimp chips, and Dachangsheng brand eel feed. After entering the water for the first time, shrimp chips account for 3 / 5, water earthworms account for 1 / 5, eel The feed accounted for 1 / 5, and after two days, shrimp slices accounted for 1 / 2 of the bait added, and eel feed ac...

Embodiment 2

[0043] A low-salinity cultivation method of Penaeus vannamei, the low-salinity cultivation method of Penaeus vannamei comprises the following steps:

[0044] a) Breeding pond treatment: the pond has an area of ​​8 mu, an aspect ratio of 4:1, and a sandy mud bottom. Before entering the water, sterilize the pond with 150kg / mu of quicklime; Water, enter the water twice, first enter the water until the water level reaches 45 cm, add bait to the breeding pond, and then enter the water again to the water level of 80 cm; set a filter at the water inlet when entering the water, and the filter is made of 60-mesh nylon thread Straight mesh with a net length of 4 meters; the bait is water earthworms, shrimp chips, and Dachangsheng brand eel feed. After entering the water for the first time, shrimp chips account for 3 / 5, water earthworms account for 1 / 5, eel The feed accounted for 1 / 5, and after two days, shrimp slices accounted for 1 / 2 of the bait added, and eel feed accounted for 1 / ...

Embodiment 3

[0050] A low-salinity cultivation method of Penaeus vannamei, the low-salinity cultivation method of Penaeus vannamei comprises the following steps:

[0051] a) Breeding pond treatment: the breeding pond has an area of ​​10 mu, an aspect ratio of 5:1, and a sandy mud bottom. Before entering the water, use 10kg / mu of bleaching powder to disinfect the breeding pond; Water, enter the water twice, enter the water for the first time until the water level reaches 50 cm, add bait to the breeding pond, and then enter the water again to the water level of 80 cm; set a filter at the water inlet when entering the water, and the filter is made of 60-mesh nylon sieve silk The straight mesh is made with a net length of 4 meters; the bait is water earthworms, shrimp chips, and Dachangsheng brand eel feed. After entering the water for the first time, shrimp chips account for 3 / 5, water earthworms account for 1 / 5, and The eel feed accounted for 1 / 5, and after two days, the shrimp slices ac...

Abstract

The invention relates to a penaeus vannamei boone low-salinity culturing method. During seed culturing, the salinity is 8 to 100%; in the phase of juvenile shrimps, the salinity of a culturing water body is increased to 6%; in the phase of middle-age shrimps, the salinity of the culturing water body is reduced to 4%; in the phase of adult shrimps, the salinity of the culturing water body is reduced to 2%. The method has the advantages that the secondary virus disease caused by the infection of pathogen of penaeus vannamei boone in seawater is avoided, meanwhile, the growth speed of the penaeus vannamei boone is ensured, and the economic benefit of a farmer is protected; by utilizing the habits of Chinese soft shell turtles, silver carps or bighead carps using planktons as foods, the amount of seaweed in water is controlled, so the water quality is improved, the waste at water body resources is avoided, and better economic benefits can be obtained.

Description

technical field [0001] The invention relates to the technical field of prawn culture, in particular to a low-salinity culture method of Penaeus vannamei. [0002] Background technique [0003] Vannamei is a high-quality high-grade food. Its meat is delicious and nutritious, and it is deeply loved by people. Because of its low saturated fatty acid and cholesterol content, it is a high-quality food for preventing cardiovascular and cerebrovascular diseases and ensuring people's health. [0004] In recent years, due to the deteriorating coastal aquaculture environment, the disease of Penaeus vannamei has frequently broken out; the current culture of Penaeus vannamei in my country is generally in the form of pond culture. Whether it is traditional pond culture or high-level pond culture, it is achieved by installing multiple aeration machines and A large number of water changes to maintain a high stocking density. This farming method has the problems of energy consumption, wat...
