Embodiment 1
[0024] The following process steps can be used to hatch fish fry with sticky fish eggs:
[0025] (1) Preparation of fish roe: Put sticky fish roe in a container, add 0.3% sodium chloride solution and male fish sperm, stir for 40 seconds, the amount of male fish sperm added per 50 ml of fish roe is 0.5 milliliters, the amount of adding 0.3% sodium chloride solution is 5 milliliters;
[0026] (2) Fish eggs attached to the hatching mesh: place the hatching device in the water of the pool in a semi-submersible manner. One person splashes the fertilized sticky fish eggs on the water surface, and the other person pulls the handle of the hatching device and shakes it horizontally from side to side continuously for hatching device to disperse and evenly adhere fish eggs to the hatching mesh of the hatching device; sprinkle 50 ml of viscous fish eggs after fertilization on each hatching mesh of 60 x 40 cm;
[0027] (3) Suspension of the hatching mesh: take out the hatching mesh unifor...

Embodiment 3
[0043] The following process steps can be used to hatch fish fry with sticky fish eggs:
[0044] (1) Fish egg preparation: put sticky fish eggs in a container, add 0.3% sodium chloride solution and male fish sperm, stir for 60 seconds, and add 1 ml of male fish sperm per 100 ml of fish eggs; The amount of adding 0.3% sodium chloride solution is 10 milliliters;
[0045] (2) Fish eggs attached to the hatching mesh: place the hatching device in the water of the pool in a semi-submersible manner. One person splashes the fertilized sticky fish eggs on the water surface, and the other person pulls the handle of the hatching device and shakes it horizontally from side to side continuously for hatching device to disperse and evenly adhere fish eggs to the hatching mesh of the hatching device; sprinkle 100 ml of viscous fish eggs after fertilization on each 60×40 cm hatching mesh;
[0046] (3) Suspension of the hatching mesh: take out the hatching mesh uniformly adhered to the sticky ...
