[0019] Sound equipment 19 is arranged in the transport case 1 on the four side surfaces, which can create a more authentic undersea or underwater world.

[0020] One end of the air exchange pipe 14 located in the fish tank 2 is close to the upper end of the fish tank 2.

[0021] The anti-stress solution comprises the following parts by weight of components: 10 parts of clove essential oil, 10 parts of isoeugenol, 10 parts of eugenol, 70 parts of food-grade β-cyclodextrin, 100 parts of fresh water and 150 parts of crushed ice water, and the clove essential oil, the isoeugenol or the eugenol can also be replaced with single essential oil, isoeugenol or eugenol.

[0022] In a concrete implementation process of the present invention, the display screens arranged are convenient for displaying an undersea or underwater scene, and the sound equipment is used for playing undersea or underwater sounds, which are integrated to disturb the fish, as if the fish are living in the original water, and give the fish an immersive experience; the anti-stress solution is added into the fish tank, then an appropriate number of fish are put into each space separated by the interlayer trays, and ten minutes later, the refrigeration system is started to reduce the temperature of the fish tank, thus the fish are kept alive at a low temperature; during transport, a temperature control mode is adopted to make the fish live in a semi-dormant or completely dormant state, so as to reduce metabolism, reduce mechanical damage and prolong survival time, thus the purpose of long-distance transport is achieved; in addition, as the anti-stress solution contains a natural anesthetic, only a small amount of chemical components is needed to take effect in a relatively short time to make the fish have no swimming activity and lack of response to external stimuli, so no stress response will appear, and losses are reduced; such a small amount of natural anesthetic will not cause the problem of chemical residue, and will not harm the fish; and even if a larger amount of natural anesthetic is inhaled, the anesthetic is easy to be absorbed and metabolized by the body because of the food-grade β-cyclodextrin.

[0023] The sound equipment, the display screens, the refrigeration system, the first solenoid valve, the second solenoid valve, the third solenoid valve, the oxygen generator, the oxygen content meter, the temperature detector and the monitor are electrically connected with a control terminal, and the electrical appliances are controlled by the control terminal, which is to control whether the oxygen generator generates oxygen, control the opening or closing of the first solenoid valve, the second solenoid valve and the third solenoid valve, and control whether the display screens play videos or what kind of videos are played; and the conditions of the fish and the temperature in the fish tank are known through the temperature detector and the monitor.

[0024] The present invention has the following operating principle: in order to increase the water solubility of clove essential oil and the absorption thereof by fish, thus improving the anesthetic effect thereof, the essential oil can be used in combination with food-grade β-cyclodextrin; food-grade β-cyclodextrin can improve the therapeutic response of an analgesic drug, and cyclodextrins can be found in at least 35 pharmaceutical products used as anticancer agents or analgesic and anti-inflammatory drugs for use in human body. This is consistent with the findings of several studies. The studies show that compared with a single drug, drugs in the form of inclusion complexes with cyclodextrins may be beneficial to the human in terms of solubility, stability and ability to improve the pharmacological responses. Therefore, eating fish that have the anti-stress solution in body is also beneficial to human body.

[0025] The formation of inclusion complexes between food-grade β-cyclodextrin and different molecules has been extensively studied in literatures. In this way, the behavior of the molecules is successfully altered, for example by making the molecules more soluble in water. Food-grade β-cyclodextrin consists of a group of natural annular oligosaccharides derived from starch, in which six, seven or eight glucose molecules are combined via α(1-4) glycosidic bonds to form cylindrical structures called α-, β- and γ-cyclodextrins; The central cavities of the molecules are hydrophobic, the outer edge of the wall surrounding each cavity is hydrophilic, and inclusion complexes are formed by the hydrophobic cavities with a variety of organic host molecules. Food-grade β-cyclodextrin can be considered as a nanoencapsulation agent, and the formation of cyclodextrin-host complexes is equivalent to molecular encapsulation because the host molecules are separated from each other and dispersed in oligosaccharide matrix at molecular level.

[0026] The present invention and the embodiment thereof are described above. The description is not restrictive, and the actual structure is not limited thereto. To sum up, any structure and embodiment similar to the technical solution of the present invention designed by those ordinary skilled in the art under the enlightenment of the present invention without departing from the purpose of the present invention and without making any creative contribution shall fall into the protection scope of the present invention.
