Problems solved by technology

However, the conventional low-temperature transportation method still has the possibility of bacterial infection during the transportation process, and the survival rate of the carp is still not high due to the nature of the carp

Embodiment 1

[0017] The new method of long-distance transportation of live catfish is realized through the following aspects:

[0018] (1) Transportation water body control: Use high nitrogen + high oxygen gas to inflate the transportation water body, so that the nitrogen volume in the transportation water body accounts for 35% of the total gas volume, and oxygen accounts for 65%;

[0019] (2) Quenching treatment: Add ice cubes to the transport water body, the amount of ice cubes added is such that the water temperature of the transport water body drops by more than 10°C within 5 minutes, and the water temperature of the transport water body is guaranteed to be 8°C;

[0020] (3) Acute heat treatment: After the fish is transported to the destination, take out the fish in step (2), and immediately add local normal temperature water according to the fish:water weight ratio of 1:5, so that the fish can quickly recover to the outside world within 5 minutes. the same temperature;

Embodiment 2

[0023] The new method of long-distance transportation of live catfish is realized through the following aspects:

[0024] (1) Transportation water body control: Use high nitrogen + high oxygen gas to inflate the transportation water body, so that the nitrogen volume in the transportation water body accounts for 55% of the total gas volume, and oxygen accounts for 45%;

[0025] (2) Quenching treatment: add ice cubes to the transport water body, the amount of ice cubes is added so that the water temperature of the transport water body drops by more than 10°C within 5 minutes, and the water temperature of the transport water body is guaranteed to be 12°C;

[0026] (3) Acute heat treatment: After the fish is transported to the destination, take out the fish in step (2), and immediately add local normal temperature water according to the fish:water weight ratio of 1:3 to quickly restore it to the same temperature as the outside world within 5 minutes. temperature;

Abstract

The invention discloses a novel method for transporting culter living bodies remotely. The novel method comprises the steps of control on transportation water body, rapid cooling treatment, rapid heating treatment, microcapsules adding in a transport tank and other aspects of control. The novel method for transporting the culter living bodies remotely has the advantages that from many aspects suchas culter itself, environment control and the like, the culter body surface has no damage, the survival rate of the culter transportation is effectively improved (reaching up to 90% or above), the sales appearance of the culter is improved, and the freshness of the culter is kept.

Description

technical field [0001] The invention relates to a new method for long-distance transport of live carp, belonging to the technical field of carp culture. Background technique [0002] Crawfish has high nutritional value, but Crawfish is irritable, jumpy and adventurous, and has less mucus on the body surface, weak skin, and easy to fall off scales. The fish bones in the body are relatively small and easy to be injured. Studies have shown that transportation activities including a series of strong stimulation operations such as fishing, transshipment, and confinement will increase the cortisol hormone level in the carp, which in turn induces faster metabolism, disease resistance, and hypoxia tolerance in the fish. weakened, its survival rate is significantly reduced, often causing serious economic losses. [0003] In the prior art, the methods for improving the survival rate of carp transport mainly include low-temperature transportation, oxygenated transportation, anesthesia...
