Embodiment 1

[0017] A number of crucian carp were selected from the Chaimi River Basin in Huai’an City, with an average body length of 15.5±1.5cm and an average weight of 54.2±10.0g. They are healthy and active, uniform in size, complete in scales, healthy and disease-free; The water is tap water inflated by an air pump for at least 24 hours; then, transfer the live fish to the edible alcohol diluent to induce dormancy, and keep them alive for 12 hours at 5°C without water; the alcohol content of the edible ethanol-containing diluent is public The ethanol-containing diluent in the patent "Method for keeping freshwater fish alive without water" CN101107922A; then, revive in clean water at room temperature, rest for 50 hours; secondly, transfer to edible ethanol diluent to induce the second dormancy, and place it at 5°C Keep alive without water for 12 hours; finally, resuscitate in clean water at room temperature.

Embodiment 2

[0022] Select a number of crucian carp from the Chaimi River Basin in Huai’an City. The body length of crucian carp is 10-12cm, and the weight is 100-150g; first, stop feeding in clean water at room temperature for 35 hours, and the temporary breeding water is tap water inflated by an air pump for at least 24 hours; Put it into the liquor diluent, induce dormancy, and keep it alive without water at 12°C for 8 hours; wherein, the alcohol content of the ethanol-containing liquor diluent is the ethanol-containing diluent in the published patent "Method for keeping freshwater fish alive without water" CN101107922A ; Then, revive in clean water at room temperature, rest for 27 hours; secondly, transfer to liquor diluent to induce the second dormancy, and keep alive for 8 hours at 12°C without water; finally, revive in clean water at room temperature.

[0023] Repeated this many times, since the first induction timing, the ultimate survival time of crucian carp can reach 126 hours. ...

Embodiment 3

[0025] Select a number of crucian carp from the Chaimi River Basin in Huai'an City. The body length of crucian carp is 10-12cm, and the weight is 100-150g; first, stop feeding in clean water at room temperature for 20 hours, and the temporary breeding water is tap water inflated by an air pump for at least 24 hours; Put it into the liquor diluent, induce dormancy, and keep it alive without water for 5 hours at 20°C; wherein, the alcohol content of the ethanol-containing liquor diluent is the ethanol-containing diluent in the published patent "Method for keeping freshwater fish alive without water" CN101107922A ; Then, revive in clean water at room temperature, and rest for 5 hours; secondly, transfer to liquor diluent to induce the second dormancy, and keep alive for 5 hours at 20°C without water; finally, revive in clean water at room temperature.

Abstract

The invention discloses a method for anhydrously surviving freshwater fish through repeated dormancy, at least comprising two times of dormancy. The times of the repeated dormancy are selected according to the practical needs of transportation distance and time. The method comprises the following steps of: temporary culture, first dormancy, recovery convalesce, second dormancy and convalesce. During the transportation of marine products, repeated dormancy survival is carried out on the same batch of live fishes to prolong the anhydrous survival time and be beneficial to the living body transportation of the live fishes.

Description

technical field [0001] The invention relates to a method for keeping freshwater fish alive without water, in particular to a method for keeping freshwater fish alive without water in repeated dormancy. Background technique [0002] As we all know, there is often a distance between the place of origin and the place of consumption of aquatic products. The transportation of live fish has become an indispensable and important link in the circulation of aquatic products. It is the most effective way to maintain the best freshness of aquatic products and meet the needs of consumers. Because live fish leaves water and is easy to die, existing live fish transportation needs live fish to be placed in the container of holding water and real-time oxygenation. However, fish transport vehicles equipped with oxygen cylinders are not allowed to pass through the tunnel; if they brake suddenly during driving, the total weight of the fish transport vehicle full of live fish will increase rapi...
