Example Embodiment

[0012] The technical solutions of the present invention will be described in detail below in conjunction with specific implementations:

[0013] 1. Stop feeding: stop feeding the commodity sturgeon (0.75~3.5kg / tail) to be transported for 2~3d to empty the digestive tract to reduce the excretion of fish feces and prevent the deterioration of the transportation living environment.

[0014] 2. Cooling: Put the sturgeon whose digestive tract has been emptied into water at a temperature of 1 to 2°C to quickly cool it down to make it in a cold paralyzed state. The cooling time is 10 to 15 minutes. During this time, the air pump is used to increase oxygen for the fish. The body temperature is close to the water temperature and is in a state of shock. Hold the tail handle of the fish body with your hand, and let the fish head face down. Generally, if the fish body does not move or the gill cover is slightly moved, the fish body is already in a cold paralyzed state, and you can pack it.

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...
