Embodiment 1

[0028] A novel method for transporting Atlantic salmon without water, comprising the following steps:

[0029] (1) Pre-treatment of Atlantic salmon: Put the disease-free and healthy Atlantic salmon into the temporary storage tank or temporary storage tank, turn on the air compressor to oxygenate the water, and adjust the water temperature to 13°C to keep the water environment clean (turn on water circulation filter equipment), stop feeding for 32 hours;

[0030] (2) Atlantic salmon dormancy: Slowly cool the Atlantic salmon treated in step (1) at a cooling rate of 2.3°C per hour, down to 8°C; Introduce carbon monoxide into the water at a rate of 0.6L / min, and at the same time, inject nitrogen into the water at a rate of 0.6L / min. After 14 minutes, the Atlantic salmon loses balance, and the respiratory rate is significantly reduced, and it is in a static state. At this time, the Atlantic salmon enters a dormant state;

Embodiment 2

[0042] A novel method for transporting grouper without water, comprising the following steps:

[0043] (1) Pre-treatment of grouper: Put the disease-free and healthy grouper into the holding pond or bucket, turn on the air compressor to oxygenate the water, and adjust the water temperature to the optimal living temperature of the grouper 22°C, keep the water environment clean (turn on the water circulation filter equipment), stop feeding for 28 hours;

[0044] (2) Grouper dormancy: Slowly cool down the grouper treated in step (1), at a cooling rate of 3°C per hour, down to 10°C; Carbon monoxide was introduced into the water at a rate of 0.14 L / min. At the same time, nitrogen gas was introduced into the water at a rate of 0.14 L / min. After 13 minutes, the grouper lost its balance, and its breathing rate decreased significantly, and it was in a static state. At this time, the grouper entered dormant state;

Embodiment 3

[0057] A novel method for transporting tilapia without water, comprising the following steps:

[0058] (1) Tilapia pre-treatment: put the disease-free and healthy tilapia into the holding pond or temporary holding bucket, turn on the air compressor to oxygenate the water, and adjust the water temperature to the optimal living temperature of the tilapia 25°C, keep the water environment clean (turn on the water circulation filter equipment), stop feeding for 40 hours;

[0059] (2) Tilapia dormancy: Slowly cool down the tilapia treated in step (1), at a cooling rate of 2.5°C per hour, down to 13°C; Introduce carbon monoxide into the water at a rate of 0.52 L / min, and at the same time, inject nitrogen into the water at a rate of 0.52 L / min. After 12.5 minutes, the tilapia lost its balance, and its breathing rate decreased significantly, and it was in a static state. At this time, the tilapia go to sleep;

[0060] (3) Pressure combined with modified atmosphere packaging: move the...

Abstract

The invention relates to a fish life-keeping transportation method, in particular to a novel fish water-free life-keeping transportation method. The method includes the following steps of live fish pretreatment, live fish dormancy through a carbon monoxide-nitrogen method, pressure combined modified atmosphere packaging, life-keeping transportation and slow warming awakening. The method has the advantage that a dormancy method that slow cooling is combined with carbon monoxide and nitrogen is adopted to enable live fish to enter the dormancy state, the dormancy effect can be achieved without reducing water temperature to the ice temperature, and a large amount of time and electricity cost are saved. No harmful reagent is adopted, the carbon monoxide and the nitrogen which are low in cost and less in dosage are adopted to promote dormancy of the live fish and have no toxic and side effects on fish bodies and human bodies, transportation and eating safety is greatly improved, and cost is reduced. Mixed gas of helium and oxygen is adopted, meanwhile certain pressure is added, oxygen absorption and utilization efficiency of the fish is effectively improved, the living time of the fish is prolonged, and the survival rate is improved.

Description

technical field [0001] The invention relates to a transport method for keeping fish alive, in particular to a novel transport method for keeping fish alive without water. Background technique [0002] Our country is rich in fish resources and various in variety. It has the characteristics of high protein, low fat, rich and balanced nutrition, etc. It has already become one of the most important high-quality animal protein sources for human intake. In recent years, my country's fishery has developed rapidly, and its output has increased year by year. The domestic live fish transportation market is huge. Problems such as northward diversion, northward fish transport to southward, and difficulty in transporting marine fish have arisen, thereby greatly limiting the development of the live fishery sales market. [0003] At present, the main way of live fish transportation is still water transportation, but because of the large amount of water carried in the transportation process...
