Problems solved by technology

[0005] But above-mentioned existing method all is to reduce the temperature of live fish transporter as basic train of thought, this cooling water tank transportation method that uses live fish transporter has cooling water tank cost height, can't adapt to the difference of low temperature physiological characteristic of each fish species, needs specialized Vehicles, long-term transportation cause low survival rate of marine organisms and other disadvantages
In addition, the above-mentioned anesthesia transportation method may cause people's concerns about food safety, while the electric shock transportation method is difficult to popularize and apply due to the difficulty in operation, suffocation and death of fish and the decline in fish quality.

Embodiment 1

[0064] Example 1: Analysis of Respiration Activity and Intrinsic Biological Rhythm of Flounder

[0065] First, in order to understand artificial hibernation using the internal biological rhythm of marine organisms, it is necessary to analyze the internal biological rhythm possessed by the target fish.

[0066] The experimental conditions for measuring the internal biological rhythms of fish are very demanding. In this experimental condition, at least two or more external environmental conditions must maintain a certain state before it can be identified as an intrinsic biological rhythm (Palmer 1995). Because fish have eyes, seeing light will affect melanin, which will affect the action and physiological activities of fish, making it difficult to observe the internal biological rhythm. In the present invention, a BOD incubator (VS 1203P5N, Vison Co., Seoul, Korea) capable of shielding light and maintaining a specific water temperature (Fig. 4: 19°C, Fig. 6: 21.5°C) was used. ...

Embodiment 2

[0067] Example 2: The average oxygen consumption of flounder according to the decrease of seawater temperature

[0068] According to the analysis method and data of flatfish respiratory activity and internal biological rhythm in the above-mentioned embodiment 1, use the artificial hibernation induction device of the present invention to determine that when the temperature of seawater containing marine organisms gradually decreases, the oxygen consumption of the above-mentioned marine organisms changes significantly Seawater temperature with reduced or no change.

[0069] As a result, as shown in FIG. 8 , the water temperature was lowered from 13° C. to 10° C., and the survival of flatfish was not affected in any way. Therefore, the inventors maintained the seawater temperature at 13°C for 10 minutes, exposed it at 12°C for 20 minutes, and exposed it at 11°C for 30 minutes, and gradually increased the exposure time as the temperature decreased. 120 minutes of exposure time (10 m...

Embodiment 3

[0075] Example 3: Artificial hibernation experiments using live fish and flounder

[0076] Next, the live fish and flounder that have entered artificial hibernation are placed in a box whose internal temperature is kept at 5°C, and the whole surface of the fish is covered with wet Korean paper, and the box is sealed for storage. Recorded the change with storage time, the maintenance time of the live fish and flounder in the above-mentioned box under anhydrous state, and the survival rate of the above-mentioned live fish and flounder, the results are shown in Table 2.

[0077] [Table 2: Results of artificial hibernation experiments using live fish and flounder]

[0078] experiment

[0079] As shown in Table 2, compared with the existing methods, the live fish and flounder that have used the artificial hibernation induction technology of the present invention and the water-free transport packaging technology have a long maintenance time in anhydrous state, and the surv...

Abstract

A method and an apparatus for inducing artificial hibernation of marine animal, wherein the temperature of sea water with marine animals is gradually lowered in stepwise process, while the sea water temperature is kept as is for a predetermined period of time at each step of lowering temperature, whereby the predetermined period of time maintained for each step of the lowered temperature is gradually increased to a point where changes of oxygen consumption by the marine animals greatly decreased or the changes of oxygen consumption is reached almost zero, and starting from this point, the time of constantly maintaining the sea water temperature at each step is gradually reduced to thereby ensuring a long survival rate (viability) of marine animals.

Description

technical field [0001] The invention relates to an artificial hibernation induction method for marine organisms and a device thereof, which is characterized in that the seawater temperature in which the marine organisms live is reduced in stages, and the temperature maintenance time of each cooling stage is gradually extended. Background technique [0002] With the rapid development of aquaculture technology in the 1980s, since the early 1990s, the production of high-grade aquaculture fish in South Korea has continued to increase (the total production of shallow sea aquaculture fish in 1997 was 39,121 tons), and with the increase of national income, Live fish consumption has also increased significantly. [0003] However, at present, when transporting marine organisms including live fish in Korea, they rely on low-density transportation technologies (accounting for 15 to 20% of the total weight) such as special vehicles for live fish. Like this, because of the prolongation ...
