Embodiment 1

[0051] A method for transporting crucian carp in ice temperature without water, comprising the following steps:

[0052] (1) Dormancy of crucian carp: put the healthy and vigorous crucian carp caught in the temporary culture system, and adjust the water temperature to about 20°C, stop feeding for 21 hours; take out the crucian carp with a length of about 12 cm and put it into the culture tank, , remove fish with poor constitution and scars;

[0053] Then the crucian carp was transferred to a culture tank with a temperature controller, the initial temperature in the tank was 20°C, and the water environment in which the crucian carp was located was cooled. The corresponding relationship is:

[0054] When cooling down to the temperature range of 20-10 °C, the cooling rate is 4 °C per hour;

[0055] When the temperature is lowered to the temperature range of 10-5°C, the cooling rate is 1°C per hour;

[0056] When the temperature in the culture tank drops to 5°C, move the crucia...

Embodiment 2

[0089] The method for transporting carp under ice temperature without water, comprises the following steps:

[0090] (1) Dormancy of carp: put the healthy and vigorous carp caught in the temporary culture system, and adjust the water temperature to about 20°C, stop feeding for 26 hours; take out the carp with a length of about 26 cm and put it in the cultivation tank, and at the same time , remove carp with poor constitution and scars;

[0091] Then transfer the carp to a culture tank with a temperature controller. The temperature in the tank is about 20°C. The water environment in which the carp lives is cooled. The corresponding relationship is:

[0092] When cooling down to the temperature range of 20-10 °C, the cooling rate is 3.5 °C per hour,

[0093] When cooling down to the temperature range of 10-5°C, the cooling rate is 1.5°C per hour;

[0094] When the temperature in the culture tank drops to 5°C, move the carp to an anhydrous low-temperature incubator to continue...

Embodiment 3

[0116] A method for transporting salmon at ice temperature and without water, comprising the following steps:

[0117] (1) Dormancy of salmon: put healthy and vigorous salmon in the holding system, adjust the temperature of the water in the tank to about 20°C, stop feeding for 29 hours; take out the 32cm long salmon Put the salmon into the culture tank, and at the same time, remove the salmon with poor constitution and scars;

[0118] Then transfer the salmon to a culture tank with a temperature controller. The water temperature in the tank is about 20°C, and the water environment where the salmon is located is cooled. The corresponding relationship between the cooling gradient and the cooling rate is:

[0119] When cooling down to the temperature range of 20-10 °C, the cooling rate is 5 °C per hour;

[0120] When the temperature is lowered to the temperature range of 10-5°C, the cooling rate is 2°C per hour;

[0121] When the temperature in the culture tank drops to 5°C, m...

Abstract

The invention relates to a transport method for freshwater fish kept alive without water, in particular to a transport method for the freshwater fish kept alive without water at ice temperature. The transport method comprises the following steps of: fostering the freshwater fish and carrying out temperature reduction and dormancy on the freshwater fish; transferring the freshwater fish into an inflating bag, oxygenating and sealing; and transporting the inflating bag to a destination and wakening the freshwater fish. The transport method is characterized in that the temperature reduction and dormancy means that gradient temperature reduction is carried out on the freshwater fish to ice temperature; and the wakening for the freshwater fish means that the freshwater fish is wakened by gradient temperature reduction. The invention has the advantages that no chemical agent is used, so that the freshwater has no side effect on a human body, potential safety hazards are reduced and the nutrient value of the freshwater is saved to the maximum extent; the cost is low; and the survival time of the freshwater fish can reach 6-81h and the survival rate of the freshwater fish reaches over 95 percent. The transport method disclosed by the invention is simple and easy for operation, has high automatic degree and can be used for realizing large-batch transportation.

Description

technical field [0001] The invention relates to a transportation method for keeping freshwater fish alive, in particular to a transportation method for keeping freshwater fish alive under ice temperature and without water. Background technique [0002] As people's demand for fish products tends to be fresh and alive, people pay more and more attention to the preservation and transportation of fish products. At present, the transportation of commercial live fish mainly includes short-distance water transportation and live anesthesia transportation. However, when using these methods to transport live fish, it will encounter hypoxia, carbon dioxide increase, pH change, water temperature change, fish mucous membrane shedding, body surface damage, etc. due to shaking, resulting in deterioration of fish product quality and food safety, etc. question. It is an urgent problem to realize the industrialization of fish products to develop new transportation methods of fish products t...
