Embodiment 1

[0017] Embodiment 1: According to the prevention and control method of the present invention, the following technical measures are adopted to prevent and control the black sperm pod disease of Litopenaeus vannamei.

[0018] 1. Cultivation water treatment

[0019] (1) First-level sand filter: The seawater in the natural sea area is pumped up and filtered through the first-level sand filter, that is, coarse filtration. This level of filter can be installed in the sea or on land, mainly to block rough and miscellaneous matter and silt action;

[0020] (2) Disinfection and precipitation with chlorine-containing disinfectant: Put the seawater that has passed the first-grade sand filter into the sedimentation tank, add sodium hypochlorite to make the concentration of available chlorine in the water reach 10 mg / L, and add an appropriate amount of sodium thiosulfate to neutralize after 24 hours Residual chlorine, aeration for 24h;

[0021] (3) Secondary sand filtration: the seawater...

Embodiment 2

[0033] Embodiment 2: According to the control method of the present invention, the following technical measures are adopted to prevent and control the black sperm pod disease of Litopenaeus vannamei.

[0034] 1. Cultivation water treatment

[0035] (1) First-level sand filter: The seawater in the natural sea area is pumped up and filtered through the first-level sand filter, that is, coarse filtration. This level of filter can be installed in the sea or on land, mainly to block rough and miscellaneous matter and silt action;

[0036] (2) Disinfection and precipitation with chlorine-containing disinfectant: Put the seawater that has passed the first-grade sand filter into the sedimentation tank, add sodium trichloroisocyanurate to make the concentration of available chlorine in the water reach 10 mg / L, and add an appropriate amount of sulfur after 24 hours Sodium sulfite neutralizes residual chlorine and aerates for 24 hours;

[0037] (3) Secondary sand filtration: the seawat...

Embodiment 3

[0049] Embodiment 3: According to the control method of the present invention, the following technical measures are adopted to prevent and control the black sperm pod disease of Litopenaeus vannamei.

[0050] 1. Cultivation water treatment

[0051] (1) First-level sand filter: The seawater in the natural sea area is pumped up and filtered through the first-level sand filter, that is, coarse filtration. This level of filter can be installed in the sea or on land, mainly to block rough and miscellaneous matter and silt action;

[0052] (2) Disinfection and precipitation with chlorine-containing disinfectant: Put the seawater that has passed the first-grade sand filter into the sedimentation tank, add lime chloride to make the available chlorine concentration in the water reach 10 mg / L, and add an appropriate amount of sodium thiosulfate after 24 hours Neutralize residual chlorine and aerate for 24 hours;

[0053] (3) Secondary sand filtration: the seawater disinfected and prec...

Abstract

The invention provides a method for preventing and treating black spermatophore disease of Litopenaeus vannamei, falling into the field of aquaculture disease prevention and treatment. The method is mainly realized through technical measures including aquaculture water treatment, aquaculture environment control, feeding of high-quality baits, drug application and artificial black spermatophore removal by extrusion. The method has convenient application, curative rate up to above 90%, low death rate of male prawn, and no need of cooperation with ripened female prawn. Female prawn ripening and spawning can be performed after re-culture and ripening of diseased male prawn. The method can realize reasonable production arrangement and save production cost.

Description

technical field [0001] The invention relates to a method for preventing and treating the black sperm pod disease of Litopenaeus vannamei, belonging to the field of aquatic disease prevention and control. Background technique [0002] Black sperm pod disease refers to a disease in which the sperm pods of Litopenaeus vannamei males turn black, and the sperm in the sperm pods have low fertilization ability or lose their fertilization ability. After the disease, the sperm in the black sperm pods do not have the ability to fertilize or have poor fertilization energy, resulting in the failure of artificial reproduction of Litopenaeus vannamei. [0003] At present, black sperm pods are mainly transferred from the sperm pods in the male shrimps by mating with mature female shrimps, and new sperm pods are re-formed in the sperm pods, so as to achieve the purpose of prevention and control. However, this method requires the cooperation of mature female shrimp. Due to the poor fertiliz...
