Problems solved by technology

However, it is directly transported with water. Also because crayfish have a relatively fast metabolism, they are packed densely during transportation, and a small amount of water will be polluted quickly, which will affect the survival rate of crayfish even more.

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...

Abstract

The invention discloses a method for improving the transport survival rate of young crayfish. The method comprises the following five steps: hanging a net for trapping, sorting young crayfish, carrying out anti-stress treatment, carrying out transportation and freely breeding the young crayfish. The method has the advantages that the young crayfish can be prevented from being damaged during fishing through the method of hanging the net for trapping; mud spitting treatment is carried out and powder of vitamin C and vitamin E is scattered, so that the box body is prevented from being polluted ina transportation process, and body resistance of the young crayfish is increased; proper humidity, temperature and oxygen content in the environment where the young crayfish are located are effectively maintained in the transportation process, and meanwhile, the damage of harmful gas or bacteria to the young crayfish is avoided; and soaking is carried out for a plurality of times before free breeding is carried out, so that overmuch water supplement to the crayfish at one time is avoided. Through the transportation process disclosed by the invention, the survival rate of the young crayfish after transportation can reach 98% or above, and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of aquatic live body transportation, in particular to a method for improving the survival rate of crayfish seed transportation. Background technique [0002] In recent years, the crayfish market has been very hot. Crayfish has the characteristics of less investment, quick results, and high benefits. Crayfish farming is increasingly becoming one of the hot spots in freshwater farming. Whether it is the price of adult shrimp or seedlings is also rising steadily, so in the process of our breeding, whether it is the purchase of shrimp fry before breeding or the sale of adult shrimp after breeding, there is a problem that needs to be involved, that is, transportation. Basically, as long as crayfish are cultured, transportation is inevitable, because for farmers, if they want to buy good shrimp species, in many cases, it cannot be solved by buying some wild crayfish locally. It involves the introduction of high-q...
