Embodiment 1

[0030] A physical control device that stimulates Cryptocaryoniasis is a metal mesh 1 made of a copper alloy material, and the diameter of the mesh 2 is 300 μm; the copper alloy material is a copper alloy composed of copper elements, zinc elements, aluminum elements and nickel An alloy synthesized by elements, wherein the mass content of copper is 60%-65%.

[0031] Use the physical prevention and control device in this embodiment to carry out post-infection treatment on seawater cultured large yellow croaker stimulating Cryptocaryoniasis:

[0032] (1) Randomly select 540 healthy large yellow croakers (6g / fish). In a 1062L fiberglass aquarium (bottom diameter 130cm; height 80cm), a total of 360 fish were infected with a non-lethal concentration (20 worms / g fish). The fish density in the infected water body was 1L / tail, and the infection continued for 2 hours. in the dark. 360 infected fish were randomly divided into two groups (groups B and C), each containing six parallel (34...

Embodiment 2

[0044] A physical control device that stimulates Cryptocaryoniasis is a metal mesh 1 made of a copper alloy material, and the diameter of the mesh 2 is 300 μm; the copper alloy material is a copper alloy composed of copper elements, zinc elements, aluminum elements and nickel An alloy synthesized by elements, wherein the mass content of copper is 74% to 78%.

[0045] Use the physical prevention and control device among the present embodiment to carry out post-infection treatment to culture grouper stimulant Cryptocaryoniasis:

[0046] (1) randomly select 900 healthy groupers (100g / fish), infect 600 fishes with non-lethal concentration (20 worms / g fish) in 40m3 indoor cement pool, and infect water body fish density is 1L / tail, Infections lasted 2 hours and were performed in the dark. 600 infected fish were randomly divided into two groups (Group B and Group C), each containing six parallel (40m 3 Indoor cement pool), 50 fish per cement pool.

[0047] (2) Select the copper a...

Abstract

The invention discloses a physical prevention and treatment device for a coptocaryon irritans disease and an application method thereof. The physical prevention and treatment device is a metal net made of a copper alloy material and is laid at the bottom of a culture pond. A corresponding area of metal net made of the copper alloy material is used according to the area of the bottom of the culturepond. During an epidemic season of the coptocaryon irritans disease, the metal net made of the copper alloy material is laid at the bottom of the culture pond in a fixed time period before an outbreak of the coptocaryon irritans disease, and is taken out after a period of time, and the metal net is operated every other day for 8 days in all; and the metal net does not need to be used after 8 days, so that cryptocaryon irritans cysts can be basically killed and the outbreak of the coptocaryon irritans disease is avoided. The physical prevention and treatment device is high in operability, lowin cost, safe and nontoxic, can be widely applied to marine aquaculture, and is a novel physical prevention and treatment method for effectively inhibiting mass outbreak of the coptocaryon irritans disease.

Description

technical field [0001] The invention relates to a physical control device for irritating Cryptocaryoniasis and its use method, in particular to a method for making and using a copper alloy material for preventing and treating stimulant Cryptocaryoniasis, and belongs to the technical field of physical control of aquaculture. Background technique [0002] Cryptocaryoniasis is a common and extremely harmful marine fish parasitic disease. At present, the control measures for Cryptocaryon stimuli are divided into physical methods, chemical methods, and immunological methods. Physical methods mainly include freshwater immersion, temperature control, drying, rotation breeding, long-term precipitation or using ultraviolet rays and ozone to treat aquaculture water, etc. Chemical methods mainly use formalin, methylene blue, potassium permanganate, Sodium hypochlorite, sulfimidazole, copper sulfate, penicillin, etc. are used alone or in combination to treat Cryptocaryoniasis, and the ...
