Embodiment 1
[0018] Put the acquired shrimp into the pond for temporary cultivation for 2 hours to rejuvenate. By adding ice or cooling the circulating water device, the water temperature is lowered to 18°C to weaken the shrimp activity. Then pass carbon dioxide gas into the water for anesthesia, the flow rate of carbon dioxide is 1L / min, adjust the pH value to 6.0, and make the shrimp dormant. Carefully fish out the prawns, put them in a foam box covered with sponge in advance, put a piece of 350g of ice under the sponge, pack the box in a plastic bag, fill the plastic bag with oxygen and seal it, and put it in a special air box, each The box is placed in three foam boxes, and finally the box is sealed and shipped by air.

The invention discloses a litopenaeus vannamei transportation method capable of keeping litopenaeus vannamei alive without water. The method includes the steps of S1, placing the litopenaeus vannamei in water at the temperature of 15-20 DEG C, feeding carbon dioxide to anaesthetize the litopenaeus vannamei, and regulating the pH of the water to 5.5-6.5; S2, placing the anaesthetized litopenaeus vannamei on a low-temperature sponge, filling oxygen, sealing and transporting. The method has the advantages that the death rate of the litopenaeus vannamei during transportation can be lowered, reviving time is shortened, and activity after reviving is increased; the method is simple to operate, capable of increasing the equipment level of enterprises for keeping the litopenaeus vannamei alive without water and capable of increasing the survival rate of alive-keeping litopenaeus vannamei transportation; the method can evidently increase the economic benefits of alive-keeping enterprises, benefit litopenaeus vannamei farmers, promote the healthy development of litopenaeus vannamei industry and obtain good economic and social benefits.
Description
technical field [0001] The invention belongs to the technical field of live aquaculture animal transportation, and more specifically relates to a method for transporting Litopenaeus vannamei without water to keep it alive. Background technique [0002] At present, the water-free preservation technology of Litopenaeus vannamei adopts low-temperature treatment to make the prawns in a dormant state, and then carry out oxygenated and sealed packaging, and carry out air transportation under the condition of maintaining a relatively low temperature. After arriving at the destination, put them in water to revive as soon as possible , to complete anhydrous transport. [0003] However, the survival rate of the above-mentioned transportation method is still low, and after the prawns are transported to the destination, the resurrection time is long, and the vigor of the prawns is insufficient. , a method with better vitality after resurrection. [0004] Reduce the mortality of Litope...
