Problems solved by technology

However, shad is irritable, and it is easy to generate stress to stimuli such as environmental changes and manual operations, and its stress response is much stronger than that of ordinary fish. The surface of the fish is injured, and it has the characteristics of dying out of water, which makes it difficult to transport live fish
The physiological and biochemical analysis of shad under stress showed that the serum cortisol of shad rose sharply after the environment changed, showing a typical stress state. After 2 hours of transportation, the serum co...

Embodiment Construction

[0027] A method for transporting large-scale commercial shad live bodies, the steps comprising:

[0028] 1) Preparation before fishing

[0029] After the shad reaches the commercial standard, train the shad to adapt to the intervention of human behavior:

[0030] Pulling net exercise: design the pulling net according to the size of the breeding pond, drive the shad to a corner of the breeding pond, keep the density of the shad in the area where the shad gathers is 8 to 10 times the normal breeding density, and release it after 4 to 8 minutes network;

[0031] Net pulling training is 2 to 3 times a day, continuously for more than 3 days, and the density of the shad in the shad gathering area is gradually increased, and the final density reaches more than 100 tails per cubic water body;

[0032] 2) Fishing

[0033] The fishing process is carried out with water;

[0034] 3) Bagging

[0035] Immediately after the shad is caught, put it into the transport container; add the tr...

Abstract

A method of transporting live large-sized commercial shad includes the steps of firstly, preparing before fishing; secondly, fishing; thirdly, bagging; fourthly, transporting; and fifthly reviving. In training before fishing, the shade is adaptive to manual operation; during fishing, mild operation is performed to avoid damage to the body of the shad; during bagging, transporting physiological fluid is added to lower stress reaction, and ice cubes are used for cooling to enable the shad to be less active; during transporting, foam boxes are used for bagging to reduce the influence caused by external vibrations. The time of transporting the shad by the method lasts more than 10 hours, the survival rate is more than 90%, and the shad can survive for more than 2 days at the destination.

Description

technical field [0001] The technical proposal belongs to the field of aquaculture, and is specifically a method for transporting large-scale commercial shad live bodies. Background technique [0002] At present, in the conventional transportation of live fish, if anesthetics are used, after about 10 hours of transportation time, the survival rate can be guaranteed to be above 90%. However, shad is irritable, and it is easy to generate stress to stimuli such as environmental changes and manual operations, and its stress response is much stronger than that of ordinary fish. The surface of the fish is injured, and it has the characteristics of dying out of water, which makes it difficult to transport live fish. The physiological and biochemical analysis of shad under stress showed that the serum cortisol of shad rose sharply after the environment changed, showing a typical stress state. After 2 hours of transportation, the serum cortisol content increased by 20 times compared...
