On the other hand, the following describes the process of inducing artificial ovulation and spawning of freshwater eel.

The process of inducing the artificial ovulation and spawning of the freshwater eel eel is measured so that the salinity of the cultured water in the culture tank in the sensor module and the control of the salinity of the cultured water in the control tank so that the conditions of fresh water, brackish water and seawater are sequentially set. And inducing magnetization by injecting a magnetization-inducing substance for inducing magnetization and ovarian maturation of the larva under freshwater conditions of the aquaculture tank, and supplying aquaculture water after the magnetization-inducing step is executed. Supplying seawater from the discharge device to change the cultured water of the culture tank to the brackish condition, and osmotic control of the fish is made; and after the osmotic control step is performed, the seawater is supplied from the cultured water supply / discharge device to the Ovulation collected from descending fish to induce ovulation of the parent fish after changing the aquaculture water in the culture tank Also after the stage and input stage of the ovulation-inducing substance added to the material is performed it can be given that formed through the steps of inducing the natural spawning.

More specifically, according to a preferred embodiment of the present invention, a magnetization-inducing substance (eg, 17β-Estradiol) for magnetization over a period of time in a culture tank (freshwater as freshwater eel) for raising freshwater eel Will be administered over a period of time.

In other words, in the case of farmed freshwater eel, there are many cases of male sexualization due to unclear reasons. Therefore, in order to secure female parental fish, a process for inducing magnetization of the parental fish is required as a pretreatment process. The magnetization-inducing substance is mixed with the cultured water over a period of time (for example, 3 to 6 weeks).

On the contrary, according to the present invention, in order to secure the larvae of the artificial ovulation induction object, it may be fed by feeding a magnetization-inducing substance to the feed.

According to the above pretreatment process, the mother fish stays in the brackish water condition for a certain period of time while the mother fish is secured. For the brackish water condition, the seawater is gradually increased by 5 psu per day to the corresponding aquaculture, and the osmotic control process is performed. To be applied to seawater.

Once the freshwater eel has been fully adapted to seawater as aquaculture water, 20-120 mg of mullet pituitary extracts (FPE) are added to 1 kg of aquaculture water for artificial ovulation induction. Mix by day to increase gradually.

Here, according to the present invention, in the process for artificial ovulation induction, the temperature of the cultured water is reduced from 20 ± 0.5 ° C. to 16-17 ° C., and the salt concentration of the cultured water reaches from freshwater to brackish water and seawater. By gradually increasing to 35 psu, the control conditions for natural freshwater eel are similarly controlled.

In the period in which the artificial ovulation is induced from the time when the magnetization-inducing substance is introduced, a light source is provided in a corresponding culture tank so that the lighting period of the light source is 8 to 10 hours in the state of shielding sunlight. In the switching process, it is desirable to completely extinguish a 15-day cycle so that natural scattering is induced.

14 is a view for explaining the morphological characteristics of the egg generation referred to in the description of the artificial ovulation and spawning induction method of freshwater eel according to the present invention, with reference to this form for aquaculture tank by the water temperature setting button of the condition setting unit The water temperature was set to freshwater conditions and the initial temperature was set to 20 ° C, and the conditions were set to gradually increase to 26 ° C over a period of time (eg, 3 to 6 weeks) in which magnetization induction as a pretreatment process was performed. The lighting period is set to 10 hours so that the control by the controller is executed, and the cultured water tank accommodates 30 to 40 cm in length (or 2.5 to 3 years old) of wild or farmed fish.

In this state, the aquaculture water supplied to the aquaculture tank is administered with a magnetization-inducing substance (for example, 17β-Estradiol) for a predetermined period of time to perform a pretreatment process for magnetization.

According to the present invention, during the pretreatment process, the feed containing the growth hormone is fed two to three times a day to promote the growth rate.

By the above pretreatment process, the corresponding freshwater eel larvae are identified in a known manner and the magnetization induction is completed. When the magnetization induction is completed, the process proceeds to ovulation and spawning.

That is, in the process for artificial ovulation and scattering, the cultured water is set to the radix condition by the water temperature setting button of the condition setting unit, and the initial temperature is set to 20 ° C. while the lighting period of the light source is set to 8 to 9 hours. The control by the control unit is executed.

Therefore, the control unit supplies seawater to the cultured water (in this case, brine to the cooling unit (or separately supplied brine) for the brackish water conditions for the aquaculture tank, so that the salinity of the cultured water gradually increases by 5 psu per day). It is increased to allow seawater to be applied by osmotic control for approximately seven days.

Then, the supply of fresh water to the aquaculture tank is stopped and set to seawater conditions, and finally the salinity concentration reaches 35 psu, and the temperature of the aquaculture water is 20 ± during the period of ovulation and spawning induction processes. The temperature is gradually decreased from 0.5 deg. C to 16 to 17 deg. C so that control is performed.

In addition, the cultured water is mixed with 20 to 120 mg of FPE for ovulation induction with respect to 1 kg of the cultured water so as to gradually increase by day according to the lighting cycle of the light source to induce ovulation.

In addition, the feeding of the feed is stopped while supplying sufficient oxygen to the aquaculture tank.

Here, the FPE is applied to the extract homogenized with Eel Ringer solution to induce artificial maturity, while increasing the weight gain (WG%, Weight Gain = [(final body weight-initial body weight)] / The initial body weight × 100) determines the maturity level.

In the above ovulation induction process, when the FPE is mixed with the cultured water and supplied, the DHP (5-10 μg / g) may be naturally fed to the cultured water if the immature maturity is sufficient among the bloated larvae. body weight concentration) or by injecting DHP into the subject at a concentration of 2 μg / g body weight to induce ovulation.

Here, according to the present invention, based on the report that the scattering of freshwater eel is made before and after the last day, the control unit is controlled so that the lighting period of the light source is completely turned off before and after the point corresponding to the time.

On the other hand, male larvae are injected with high concentrations of HCG (1000 IU / gbody weight) in accordance with the ovulation time of the female eel to accommodate the male and male in the tank at 1: 2 ratio to induce natural spawning and fertilization.

By the above process, natural spawning and fertilized eggs are connected to the culture tank to collect the flotation tank to collect the floating eggs to induce hatching in a state where a small amount of oxygen is supplied from the hatching tank.

That is, 'A' of FIG. 1 shows the state of egg yolk and embryonic development of freshwater eel, which shows the state in which the splitting starts in the betrayal of the animal pole after 1 hour of fertilization, and 'B' is about 1 hour after fertilization. The progression of the four-cell stage (1.39 ± 0.07 mm of the diameter of the ovum) at the time of the minute elapsed, and the progression of the 16-cell stage at the time of 3 hours of fertilization are observed.

In addition, referring to 'D', the fertilized egg is composed of one large mole and two small to medium sized mole, and when the fertilized egg progresses to the blastocyst, the fertilized egg is observed after 5 hours of fertilization. At the time of 14 hours of fertilization, the middle stage of the culturing progresses to the middle stage of culturing, and 15 or more small quarters are observed around one central large quarter.

Referring to 'F', embryos are formed after 21 hours of fertilization, and after 24 hours of fertilization, the molten fusion is merged into one and 12 to 15 eradications are observed.

In addition, referring to 'G', the follicle is formed at 27 hours after fertilization, follicles are observed at the posterior follicle, and 30 hours after fertilization, cardiac formation is observed at the lower part of the head. Blood vessels are observed, and eradication at this time is observed in 24 to 30.

Referring to 'H', 33 ~ 30 hours after fertilization, 28 ~ 35 eradications are observed, the tail is separated from egg yolk, the shape of tail and heart beat is observed. Hatching begins with violent movement through the eggplant and the incubation begins. The pre-leptocephalus larvae are slightly curved around 3 mm in total length, with 40-44 eradications and about 1 hour later. The body is observed to be horizontal.

On the other hand, the feed according to the present invention is automatically supplied to the feed in the feeder, it is made by quantitatively feeding a predetermined amount of feed in the standard data according to the size, weight of freshwater eel accommodated in the culture tank.

In addition, the size and weight of the freshwater eel is made through a fish recognition sensor including a camera for taking a picture or video, and a fish analyzer for analyzing the type and growth of the fish by extracting a silhouette from the picture or video taken by the camera. .

In particular, in the present invention, the fish meal obtained from fish, including squid and / or krill, is mixed with a dietary powder containing vitamins and minerals, and the vegetable dietary sulfur is mixed. The feed powder is selectively mixed with plum extract.

In addition, the feed for fish farming is used to extract vegetable dietary sulfur, such as distillation techniques, such as three, pine and bamboo endothelium, garlic, onion, ginger, carrot and the like.

Here, the vegetable dietary sulfur is mixed in an amount of 0.01 to 0.06%, preferably 0.02 to 0.04%, based on 1 kg of the feed powder. Proteins in the body are synthesized around sulfur (sulfur synthesizes proteins by peptide bonds). When sulfur is insufficient in the body, incomplete and incomplete proteins are formed or the protein itself cannot be synthesized.

Therefore, the continuous supply of vegetable dietary sulfur in the body normalizes the cells and restores gene mutations to a healthy state, which not only induces somatic cell-improving effects, but also promotes growth and prevents infectious diseases due to enhanced immunity and reduction of fat. Improvement of meat quality is expected.

The feed powder contains a small amount of selenium (preferably 0.5 to 1) which protects cells and cell membranes from free radicals caused by peroxidation of fats by preventing oxidative damage as a component of glutathione peroxidase. Including μg, the selenium becomes extractable from fish and shellfish (eg sardines, flounder, oysters, etc.) and vegetables and grains (eg garlic, brown rice, green onions, sesame seeds, garlic, etc.).

In addition, the feed powder is effective in antiviral and anti-inflammatory and contains a small amount of organic germanium (preferably 0.5 to 1 µg) for the effect of antimutagenicity, and the organic germanium is black soybean, wolfberry, garlic, 300 seconds, Organic germanium extracted from seaweed, sewage and mushrooms, and particularly horseshoe mushroom, is preferably used.
