Embodiment 1
[0024] A method for improving the survival rate of crayfish fry transportation, the steps include
[0025] (1) Trapping with hanging nets: choose a coarse mesh with soft black texture and a mesh aperture of 3 cm, tie the mesh into a bunch every 30 cm, and place them every 5 m around the seedling pond. 2 Hang a bunch so that the bottom of the net is close to the bottom of the pond. Put the hole net into the dredge the next morning, shake it back and forth in the water, and the shrimp seedlings will fall into the dredge net. Put the shrimp seedlings in the dredge net into the pot and temporarily raise them in the cage middle. After a few hours the larvae can be collected again in the same way.
[0026] (2) Seed sorting: select the seedlings that are blue-gray, shiny, and of uniform size, try to buy shrimps that are slightly red in color, and remove the shrimps that form a pile after entering the pot in time, instead of jumping and climbing away quickly. The final confirmed shr...
