Abstract

The invention relates to the technical field of keep-alive transportation of shrimps, and provides a waterless keep-alive transportation method for shrimps in order to solve the problems that an existing waterless shrimp transportation technology has many influencing factors and unstable shrimp survival rate. The method comprises the following steps of (1) temporary rearing; (2) precooling, wherein a keep-alive agent is precooled to 6-15 DEG C, and the keep-alive agent is mixed mucus of misgurnus anguillicaudatus and monopterus albus; (3) cold shock, wherein the shrimps are soaked in the precooled keep-alive agent until the shrimps enter shock states; (4) packaging, wherein the shrimps are packaged in a packaging bag, and the packaging bag is sealed after being filled with oxygen; (5) transportation; (6) recovery. The waterless keep-alive transportation method for the shrimps can effectively relieve the stress response of the shrimps during transportation, improve the capability to tolerate hypoxia, maintain the health of the shrimps, and effectively increase the survival rate of waterless transportation, and the survival rate after the shrimps are transported for 15 hours can reach 91%.

Description

technical field

[0001] The invention relates to the technical field of shrimp preservation transportation, in particular to a method for waterless shrimp preservation transportation based on loach and eel mucus. Background technique

[0002] Litopenaeus vannamei, Penaeus monodon, Penaeus sinensis and other shrimps are rich in nutrition and delicious in quality, and are important farmed shrimps in my country. Among them, Litopenaeus vannamei has the largest output. In 2016, the total aquaculture volume of Litopenaeus vannamei in my country exceeded 1.67 million tons, including 932,000 tons in mariculture and 740,000 tons in freshwater, accounting for 50.6% of the total cultured shrimp. The main production areas of Litopenaeus vannamei are located in Guangdong, Guangxi and Jiangsu. The geographical span is large, and the transportation and preservation of aquatic products are difficult.

[0003] At present, the transportation method of fresh and live aquatic products such as ...
