Description

Live fish anhydrous transportation method based on composite functional package Technical Field The invention relates to the technical field of transportation of living bodies of aquatic products, in particular to a method for transporting living fish in an anhydrous manner based on a composite functional package. Background In the circulation process of the aquatic products, the water quality is easily deteriorated due to high density, long transportation time, jolt in the way and lack of enough water treatment equipment, so that the aquatic products are injured and die. According to statistics, in China, the loss rate of the aquatic products in the logistics link is as high as 25% -30% due to the lack of a reliable live fish transportation technology, namely about 1/4 of the aquatic products are lost in the logistics link. At present, the technical development of the transportation of fresh and alive aquatic products in China mainly comprises three types of water transportation, anhydrous transportation and circulating water live fish transportation, and each type of the transportation has advantages and disadvantages, so that the transportation of the fresh and alive aquatic products and the development of the keep-alive technology are promoted to realize the long-distance keep-alive transportation of the live fish, and the technology has become an urgent problem to be solved. The traditional water transportation has low cost and strong operability, can realize keep-alive transportation within a certain distance, but is lack of enough technical guarantee, and under the drive of economic benefit, the condition of ensuring the survival of fish by using forbidden drugs often exists. The water transportation has the defects of large volume of transportation water, difficult water quality treatment, small fish body loading capacity, large oxygen supply amount, high cost and the like. The anhydrous keep-alive transportation is a transportation method which uses no water or only a small amount of water to keep the environment moist and expose the fish to the air, and can reduce the economic cost and the pollution of waste water. Anhydrous transportation is often matched with anesthetic, and the transportation amount is more than 3 times of that of the water transportation, so that the logistics cost can be greatly reduced. The transported fish is short in time consumption for reviving, and the fish meat is more fresh and alive, so that the fish has a wide application prospect. However, the anhydrous transportation is easy to cause strong stress reaction of fish bodies, and metabolic disorder, immunity decline and even death are caused. The threshold of the anhydrous transportation technology is higher, and the special requirements on varieties are also met, so that the difficulty of large-scale popularization and application is higher. In order to ensure the survival of fish, the fish is usually put into a state similar to hibernation through dormancy induction or low temperature, the metabolism and the oxygen demand of the fish are reduced, and the transportation efficiency and the survival rate of live fish are improved. At present, the research points of the anhydrous transportation technology are condensed in two technical processes of ice temperature and anesthesia. But the ice temperature has high requirements on the environment, the operation requirement and the energy consumption. Most of the commercial anesthetics belong to forbidden medicines, and residues can be generated in fish bodies, so that the hidden danger of high food safety is caused. At present, although some additives are reported, the additives are mostly added into feeds, the time is long, and the additives cannot continuously play a role in the anhydrous transportation process. The design of a multifunctional composite package combining synergism, slow-release adsorption and immunopotentiation and the integrated application in temporary culture and transportation links have not been systematically researched. Therefore, how to develop a live fish anhydrous transportation method based on a composite functional package, which can effectively relieve transportation stress and improve the anhydrous transportation survival rate of various live fish, is a technical problem to be solved by the technicians in the field. Disclosure of Invention In view of the above, the invention provides a method for transporting live fish without water based on a composite functional package. A live fish anhydrous transportation method based on a composite functional package comprises the following steps: (1) Temporary culture before transportation, namely putting the A package and the B package into temporary culture water, and fasted temporary culturing the live fish for 1-5 days; (2) Packaging without water oxygenation, namely fishing out the temporarily-cultured fish, putting into an oxygenation bag, 2-3 fish bags in each bag, placing one bag A and one bag
