Embodiment 1

[0014] 1) Selection and temporary rearing of broodstock: 5,000 healthy broodstock with a body length of 14 cm and a weight of 35 g were selected according to the ratio of male to female at 1:2. According to the density of 30 tails / box, put the broodstock shrimp into the indoor 1000L PVC aquarium. The water in the aquarium has been pre-treated with ozone disinfection, ultraviolet disinfection and precision filter with a pore size of 1 μm, and then micronized according to the speed of 1L / min. During the entire broodstock breeding period, ensure that the water temperature is controlled at 26°C, the salinity is 28, the dissolved oxygen is guaranteed to be above 5 mg / L, the pH is 7.8, and the total ammonia nitrogen content in the water is 0.6 mg / L. According to 2% of the body weight of the prawns, the broodstock feed (purchased from Zhanjiang Hengxing South Ocean Technology Co., Ltd.) was fed every day, 4 times a day.

Embodiment 2

[0020] 1) Selection and temporary rearing of broodstock: 2,000 healthy broodstock with a body length of 16 cm and a weight of 38 g were selected according to the ratio of male to female ratio of 1:2. According to the density of 40 tails / box, put the broodstock shrimp into the indoor 1000L PVC aquarium. The water in the aquarium has been pre-treated with ozone disinfection, ultraviolet disinfection and a precision filter with a pore size of 5 μm, and micronization at a speed of 1L / min. During the entire broodstock breeding period, ensure that the water temperature is controlled at 28°C, the salinity is 30, the dissolved oxygen is guaranteed to be 6 mg / L, the pH is 8.0, and the total ammonia nitrogen content in the water is 0.5 mg / L. According to 2% of the body weight of the prawns, the broodstock feed (purchased from Zhanjiang Hengxing South Ocean Technology Co., Ltd.) was fed every day, 4 times a day.

Embodiment 3

[0026] 1) Selection and temporary rearing of broodstock: 4000 healthy broodstock with a body length of 18cm and a weight of 40g were selected according to the ratio of male to female ratio of 1:2. clean. According to the density of 35 tails / box, put the broodstock shrimp into the indoor 1000L PVC aquarium. The water in the aquarium has been pre-treated with ozone disinfection, ultraviolet disinfection and precision filter with a pore size of 4μm, and micronization at a speed of 1L / min. During the entire broodstock breeding period, ensure that the water temperature is controlled at 30°C, the salinity is 34, the dissolved oxygen is guaranteed to be 6 mg / L, the pH is 8.6, and the total ammonia nitrogen content in the water is 0.5 mg / L. According to 2% of the body weight of the prawns, the broodstock feed (purchased from Zhanjiang Hengxing South Ocean Technology Co., Ltd.) was fed every day, 4 times a day.

Abstract

The invention relates to a method for breeding the FanNaBing sterilize which can resist hickie complex symptom virus. Wherein, it comprises: (1) selecting parent shrimp while the female-male ratio is 1:2; (2) counteracting toxic substances that ejecting hickie complex symptom virus solution into the first section of muscle at the back of parent; (3) eliminating the ill and dead parents, to select the FanNaBing sterilize which can resist hickie complex symptom virus; (4) breeding parent shrimps.

Description

【Technical field】 [0001] The invention relates to a method for breeding broodstock of Litopenaeus vannamei with the property of resisting white spot syndrome virus. 【Background technique】 [0002] Litopenaeus vannamei is an important seawater economic shrimp. Because of its fast growth, strong disease resistance, and high market value, it has been valued by aquaculture farmers. In recent years, the scale of farming has been increasing. However, with the increase of farming scale and the aggravation of water environment pollution, diseases in the culture process of Litopenaeus vannamei also occur from time to time, among which the white spot syndrome (WSS) of Litopenaeus vannamei is the most harmful to farming. ). Shrimp white spot syndrome is caused by white spot syndrome virus (WSSV for short), and there is no effective drug to prevent and treat WSSV at present, so the main method to control the outbreak of WSS is prevention. In production, it has been found that some pra...
