Alive sturgeon low-temperature anhydrous transportation technology

Abstract

The present invention provides a low-temperature transportation technology without water of live sturgeon; the transported live sturgeons are not fed for 2 to 3 days and put into water with a temperature of 1 to 2 Celsius degrees for precooling for 10 to 15 minutes; and then the sturgeons are put into an insulation box in which a seal bag is laid; the air in the seal bag is extruded and the seal bag is tied tightly after oxygen is infused; after the insulation box is sealed, the sturgeons can be transported and the transportation time is less than or equal to 18 hours. Compared with the prior art, sturgeon is a sub-cold water fish which has a low temperature resistant nature and the method makes use of the nature to freeze the sturgeons for transportation without water; in this way, the volume and weight of fish transportation tools are greatly reduced and at the same time the transportation cost is reduced which is convenient for vehicle or aviation transportation. The transportation time can reach 18 to 20 hours and the survival rate in transportation can reach more than 99 percent.

Description

technical field [0001] The invention relates to a live fish transportation technology, in particular to a low-temperature anhydrous transportation technology for live sturgeon. Background technique [0002] The most traditional fish transportation method is to put the fish in the water tank and increase the oxygen supply at the same time. Although this can better reduce the difference between the transportation living environment and the original living environment of the fish, for long-distance transportation, Because the live fish is transported with water, the volume and weight of its water tank are relatively large, and the transportation cost is relatively high. The Chinese patent with the publication number CN1071803 discloses a method of hibernating, reviving and keeping fish and shrimp fresh. In this method, the fish and shrimp are firstly subjected to pre-hibernation treatment and then placed in low-temperature auxiliary materials for transportation. "Auxiliary mate...

Problems solved by technology

The Chinese patent with the publication number CN1071803 discloses a method for fish and shrimp hibernation, resurrection and freshness preservation. In this method, the fish and shrimp are first pre-hibernated and then placed in low-temperature auxiliary materials for transportation. "Auxiliary materials" are needed in the process of processing On the one hand, this increases the cumbersomeness and cost of the processing process; on the other hand, auxiliary materials need to occupy a part of the transportation space and weight, which increases the transportation cost virtually.
