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...
