Description

METHOD FOR INDUCING OVIPOSITION OF A RED SEA CUCUMBER}

The present invention relates to a method for inducing red sea ginseng spawning, and more particularly, to a method for inducing red sea ginseng spawning by increasing the fertilization rate by smoothing the spawning of the mother red sea ginseng using the water temperature stimulation method and the shade drying method.

Sea cucumbers belonging to the echinoderm are known to inhabit about 14 species in Korea, and among them, industrially important species are sea cucumbers (Stichopus japonicus). Sea cucumbers are called sea cucumbers in English.

Sea cucumbers are divided into several groups due to subtle feature differences. Among them, the same species is divided into three species: sea cucumber (cheonghaesam), red sea cucumber, and black sea cucumber. This is because not only the body color but also the distribution site, the shape of the body's elasticity or egg shape, the color change pattern of young sea cucumber after metamorphosis, and the structure of internal and external organs appear.

Most of the harvesting of sea cucumbers has been dependent only on the harvesting of wild animals by divers or divers from village fishing grounds. However, due to environmental pollution of coastal fisheries, global warming and coastal landfilling, spawning grounds and habitats have been reduced, and resources have been reduced globally due to uncontrolled overfishing. Therefore, it is urgent to recover resources by mass production of sea cucumber seedlings.

Conventional sea cucumber seedling production method is to accommodate a large number of mother sea cucumbers in a large tank without distinction between male and female and induce spawning by physical stimulus to produce a large amount of eggs at a time. This has the disadvantage of lowering the economic costs such as the purchase cost of the mother sea cucumber.

The present invention has been made to solve the above problems, the object of the present invention is to provide a method for inducing red sea ginseng scattering to increase the fertilization rate by smoothing the spawning (crystallization or eggs) of the mother red sea ginseng using the water temperature stimulation method and the shade method. have.

In order to solve the above problems, the red sea ginseng spawning method of an embodiment of the present invention is a first step of draining seawater of a tank containing red sea ginseng, a second step of drying the red sea ginseng in an inverted state for a first predetermined time, The third step of stimulating the red sea ginseng in the tank by pouring warmed seawater higher than the natural water temperature by 3 ℃, the fourth step of blocking the light irradiated to the red sea ginseng for a second predetermined time.

According to an aspect of an embodiment of the present invention, the first predetermined time is 50 minutes to 70 minutes.

According to an aspect of an embodiment of the present invention, the second predetermined time is 5 hours to 6 hours.

According to the present invention as described above, according to the present invention as described above, with the implementation of the water temperature stimulation method and the shade method, there is an advantage to smooth the spawning of the red sea ginseng by stimulating the red sea ginseng by inverting the water and inverting the red sea ginseng for a certain time. .

In addition, since it can be smoothly spawned from a relatively small mother red sea ginseng, it is possible to reduce the purchase cost of the mother red sea ginseng, and also has the advantage of improving the production rate of fertilized eggs.

1 is a flowchart illustrating a red sea ginseng scattering induction method according to an embodiment of the present invention.
Figure 2 is an image for explaining a second step of flipping red sea ginseng after drainage according to an embodiment of the present invention.

The following detailed description is only illustrative, and merely illustrates embodiments of the present invention. In addition, the principles and concepts of the present invention are provided for the purpose of explanation and most useful.

Accordingly, various forms that can be implemented by those of ordinary skill in the art, as well as not intended to provide a detailed structure beyond the basic understanding of the present invention through the drawings.

Hereinafter, the configuration and operation of the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The method of mass production of artificial seedlings of red sea ginseng proceeds to the process of fertilization and larval rearing, cultivation of prey organisms, cultivation and rearing of sea cucumbers. Here, the term 'scattering' of red sea ginseng means the male red sea ginseng male's male eggs and the red sea ginseng female's eggs through the reproductive cavity.

1 is a flow chart for explaining the red sea ginseng scattering induction method of the present invention.

As shown in Figure 1, the red sea ginseng spawning method is the first step (S10) for draining the seawater of the tank containing a number of red sea ginseng, the second step (D20) to dry the red sea ginseng upside down for a first predetermined time (S20) ), The third step (S30) for stimulating the red sea ginseng in the water tank for a second predetermined time by pouring warmed seawater 3 ℃ higher than the natural water temperature, the fourth step (S40) for blocking the light irradiated to the red sea ginseng .

The red sea ginseng spawning method of the present invention has been described as a mixed egg laying method in which male and male red sea ginseng are put in one tank, but the present invention is not limited thereto and may be applied to a selective egg laying method for separating females and males of mother red sea ginseng. Unlike sea cucumbers, red sea ginseng is more sensitive to external environment (stimulating water temperature, light, etc.), and it is very difficult to distinguish between male and female. Therefore, the male and female can be distinguished when the formulation is made through the red sea ginseng spawning induction method of the present invention. In this case, male red sea ginseng is picked up and separately accommodated, and modified by adding semen to the female red sea ginseng where the eggs are produced. In the case of the screening chaeran method, the eggs can be fertilized in the egg tank as soon as the egg of the red sea ginseng is finished, and the eggs can be fertilized again after fertilization.

For the efficiency and stability of artificial seedling production of red sea ginseng, it is important to obtain large amounts of eggs and sperm from healthy and mature mother red sea ginseng. The securing of mature mother red sea ginseng is approaching the spawning season of red sea ginseng and purchasing wild mothers and managing them artificially before the spawning season.

First step (S10) is to collect a number of mother red sea ginseng necessary for spawning 2-3 months before the spawning season and manage in the land tank before the spawning season. The mother red sea ginseng used to induce spawning is placed in a clean tank without food for three to four days before spawning stimulation, in order to excrete all wastes in the intestine and induce spawning. The temperature of the land tank maintains a natural water temperature of 15 ℃ ~ 16 ℃. The seawater in the land tank is then drained to induce spawning.

Next, in the second step (S20), after draining all the seawater in the land tank, after draining all of the seawater in the land tank, the mother red sea ginseng has a protruding black hair on the back, ie, to see the sky. It is turned over so as to be in contact with the bottom of this water tank, and it maintains for a predetermined time (50 minutes-about 70 minutes) (refer FIG. 2). Therefore, after draining, red sea ginseng is stimulated to lose moisture in the body for a predetermined time. The predetermined time for drying the red sea ginseng may vary depending on the external environment (current temperature, etc.) of the red sea ginseng.

Next, in the third step (S30), after a predetermined time has elapsed in the dried red sea ginseng (after the second step), using a heater with a water temperature controller is 3 ℃ than the natural water temperature (15 ℃ ~ 16 ℃) Highly heated (irritating water temperature) sea water is poured into a tank containing red sea ginseng (water temperature stimulation method). Therefore, after draining, red sea ginseng is stimulated to lose moisture in the body for a predetermined time (50 minutes to 70 minutes) in an inverted state. On the other hand, it is possible to supply the heated sea water repeatedly when the water temperature is lowered to measure the sea water temperature of the tank containing the red sea ginseng to maintain the warm sea water temperature.

Next, the fourth step (S40) blocks the light irradiated to the red sea ginseng for a predetermined time (here 5 to 6 hours) after the third step by the water temperature stimulation method. The method of blocking the light irradiated to the red sea ginseng may be achieved by covering the land tank with a black cloth or plank, or turning off the spawning room light in the red sea ginseng spawning room (the land tank is located in a space capable of blocking external light). There is (the shade method).

The red sea ginseng, which had been induced to spawn in response to the stimulation of red sea ginseng by the first to fourth steps, fixes the lower part of the body (back) to the tank wall, and shakes the upper half to the left and right to spawn through the reproductive cavities behind the head. Is made).

Table 1 below is experimental data according to the induction of red sea ginseng scattering according to an embodiment of the present invention.

The fertilization rate according to the red sea ginseng scattering induction method of the present invention was confirmed as shown in Table 1 through an electron microscope observation. The spawning induction of 62 red sea ginseng was 62 (47 females, 15 males), and the spawning rate was 31.5%. Therefore, according to the red sea ginseng spawning method of the present invention, it can be seen that the red sea ginseng spawning subscription rate is higher than 10% to 27%.

In addition, as a result of the observation of fertilization, the average egg spawning amount of red sea ginseng was 53.3 million, which is estimated to be 13 million (1,300 * 47 total females).
