Description

Sea cucumber and abalone seedling complex farming method {METHOD FOR CULTIVATING SEA CUCUMBER AND ABALONE SEEDS}

The present invention relates to a sea cucumber and abalone seedling complex culture method, and more particularly to a sea cucumber and abalone seedling complex culture method that is implemented to grow abalone and sea cucumber seedlings in the same tank, the cost can be reduced and the culture efficiency is increased.

With the recent development of aquaculture technology for marine organisms, abalone and sea cucumber can also be farmed and produced in large quantities.

In particular, the demand for sea cucumbers has greatly increased, and the income of the sea cucumbers is greatly increasing because the sea cucumbers are a preferred seafood for Chinese people, and their prices are much higher in China than in Korea. The sea cucumber is produced intensively from April to May and is consumed almost in China. Sea cucumbers are no exception to the overall depletion of water resources, and production in nature is gradually decreasing. Therefore, the spread of artificial seedlings are urgently needed, and the trend is attracting attention as high-income farms in the festival farms on the west coast.

In particular, in order to grow abalone and sea cucumbers, young abalones or sea cucumbers are grown in a water tank over a certain size, and then young abalones or sea cucumbers are removed from the land water tanks and then shelter is installed in the sea. The farm was put inside the farm.

In general, sea cucumbers belong to the genus Purewood, Urticula and Cucumber. Distribution The water is distributed horizontally throughout the Northeast Pacific from Korea's coastal zone and temperate seas such as Japan, Kuril and Sakhalin to the Handae Sea, and inhabits between 0 and 40m vertically. Sea cucumbers inhabit anywhere except where the low quality is pure mud. Sea cucumbers eat mainly corrosives, microorganisms and floating organisms in the sand mud. They take a nap in the sand during the day and have a lower surface in the summer, and they catch a lot during the season from April to May.

In addition, more than 100 kinds of abalone are known around the world, and several kinds of abalone, including veteran abalone, also live on the coast of Korea.

In particular, abalone has been in the spotlight as a high value-added fish species. Since 1976, full-scale artificial seedling production has been carried out, the area of farming has increased every year. The farming method also has a high survival rate of abalone and a high-density offshore cage farming method, where the larvae are discharged and harvested after growth.

In addition, abalone is an adherent fish that lives on any object and lives mainly in rocky and reef, and where brown algae breed a lot. Even in the case of farming, in order to satisfy these habits of abalone, various types of shelter that can live with abalone are being developed.

Recently, various methods of raising abalone and sea cucumbers have emerged. For example, it has been divided into upper and lower divisions in separate body parts (circular or various forms), and farmed abalone and sea cucumbers together.

However, the above-described method is expensive because the abalone feed and the sea cucumber feed are required, and the breeding space is also difficult to use efficiently. Moreover, this method was applied to the culture of sea cucumbers and abalones to some extent, but not to the cultures of sea cucumbers and abalone seedlings.

In order to solve the problems as described above, an object of the present invention is to provide a sea cucumber and abalone seedling complex culture method that is implemented to relatively reduce the cost of farming.

It is another object of the present invention to provide a sea cucumber and abalone seedling complex culture method for maximizing space utilization by breeding sea cucumber and abalone seedling in a common space.

It is another object of the present invention to provide a sea cucumber and abalone seedling complex culture method that is implemented to help reduce the cost of farming by replacing the excrement of abalone with feed of sea cucumber.

In order to solve the above object, the present invention provides a plate-type shelter having a concave-convex structure in the longitudinal direction, and a plurality of wave plates vertically installed at regular intervals so as to cross the concave-convex structure on top of the shelter. In the method of complex culture of sea cucumber and abalone seedlings in the breeding season, the process of disposing the sea cucumbers and abalone larvae in separate compartments, the process of arranging the plurality of breeders in each compartment of the tank containing sea water It is characterized in that it comprises a process of breeding until the attachment time and the step of introducing the sea cucumber larvae and abalone larvae arrived at the attachment time to the corresponding section of the tank corresponding to the population.

Since the sea cucumber and abalone seedling complex culture method according to the present invention uses the food of the sea cucumber using the excrement of the abalone, the farming cost is significantly reduced, it is possible to effectively use the culture space due to the mixed culture.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, if it is determined that the gist of the present invention may be unnecessarily blurred, detailed description thereof will be omitted.

1 is a perspective view showing a breeder that can breed together sea cucumber and abalone seedling according to the present invention, Figure 2 is a schematic diagram of a breeder showing the weekly habitat position of the sea cucumber and abalone seedling according to the present invention.

1 and 2, the breeder 10 applied to the present invention has a shelter 11, and a wave plate 12 is a plurality of vertically stacked on the upper portion of the shelter 11 at a predetermined interval. Include. The shelter 11 is formed so that regular recesses and convex parts alternately formed in the longitudinal direction to provide a habitat of sea cucumber or abalone seedlings, and the wave plate 12 is formed in a direction crossing the recesses and convex portions at equal intervals. It was. In addition, the wave plates 12 may be installed in a manner in which a plurality of the plurality of stacking plates are stacked, and at least two support bars 121 penetrating the wave plates 12 are applied to the plurality of wave plates 12. It can be implemented as a bundle. The support bar 121 in this figure is installed four places, but may be installed in more than that number. As shown in the present invention, a flat wave plate is used, but a wave plate of various shapes such as a corrugated plate having regular irregularities is applicable.

As will be described later, the one shelter 11 and the lamella 12 installed in the shelter 11 are composed of a single breeder 10, a plurality of breeders in the sea cucumber and abalone seedling culture tank (30 in Figure 3) 10 will be installed in a regular manner.

As shown in Fig. 2, the abalone (1) and sea cucumber (2) seedlings have slightly different habitats. The sea cucumber and abalone seedlings are nocturnal and hide mainly in dark cover during the day, and the shelter 11 may be provided as such cover. Again, at night the lamella 12 and shelter 11 will be the active area of the sea cucumber and abalone. Therefore, during the day, the sea cucumber seedling 2 will mainly live on the bottom 20 of the tank, more specifically, the bottom 20 of the tank overlapping the shelter 11, and the abalone seedling 1 will be the shelter ( It is attached to the rear surface of 11), that is, the lower surface of the shelter 11, and inhabits. At night, the sea cucumber and abalone seedlings are attached to the upper part of the shelter 11 or the wave plate 12 to crawl and feed.

3 is a schematic view of a water tank 30 for breeding sea cucumbers and abalone seedlings according to the present invention, although not shown, the water tank 30 includes a water supply line for introducing seawater and a drainage line through which the introduced seawater is drained. something to do.

The water tank 30 is divided into a plurality of compartments (A, B, C, D) by the partition wall 31, each of the above-described breeder 10 is installed in such a manner that a plurality is arranged at regular intervals. The water tank 30 is loaded with seawater enough to lock the breeder 10. The tank 30 is, for example, divided into compartments of A, B, C, D, to distribute the abalone or sea cucumber larvae cured in a separate tank for each compartment.

4 is a flowchart illustrating a procedure for raising sea cucumber and abalone seedlings according to the present invention.

As shown in Figure 4, the sea cucumber and abalone seedling complex culture method according to the present invention begins with supporting a plurality of breeders in the tank divided by sections of Figure 3 (step 401), the sea cucumber and abalone The larvae are not applied, and diatoms can be generated in this state. The diatoms are adhered diatoms, which are grown by attaching them to the papa using natural sunlight, and will be used as food for sea cucumbers and abalone.

The larvae are then grown in separate preparatory stages. For example, sea cucumbers grow 10 days at water temperature of 20 ° C, and abalone grow 80 hours at water temperature of 18 ° C. After this growth period, sea cucumbers and abalone larvae will be attached to the breeding pads or shelter and become self-supporting (step 405).

Thereafter, the reared larvae are separately added to the corresponding sections of the tank according to the type (step 407). For example, the sea cucumber is inserted into the A section of the tank of FIG. 3 and abalone is inserted into the B section. After a certain period of time, sea cucumbers and abalones are mixed. This period takes place after 45 to 80 days (step 409). Even if it is a young larva, the survival rate is not constant. Therefore, when the above-mentioned period is passed, the approximate survival number and growth degree of the corresponding sea cucumber and abalone larvae are determined, and the ratio of the sea cucumber and abalone larvae to be mixed and mixed can be properly adjusted by the identified population. This part is very important, the food of the sea cucumber in the present invention is largely due to the solution of feces of abalone. For example, if sea cucumbers and abalone larvae are directly collected in a larvae incubator, the population of sea cucumbers will not match the abalone feces due to the imbalance of populations. For example, if the population of abalone is relatively large compared to sea cucumbers, even if the sea cucumbers ingest the excrement of abalone, the feces will remain, and the seawater will be contaminated by the bottom of the tank, and if the number of abalone is relatively small compared to the sea cucumber Because of the lack of food for sea cucumbers (dung feces of abalone), a separate feed for sea cucumbers is required, which increases costs.

Although the above-mentioned period is preferable, the sea cucumber larvae and abalone larvae which have come to be attached may be mixed immediately, and 80 days may be passed.

As a result, the sea cucumber and abalone larvae after the mixed input have a considerably high survival rate and normal feeding activity. As described above, these sea cucumbers and abalone are nocturnal, and at night, they will feed on crawling papa, or they will ingest the feces of abalone on the top of the shelter or on the bottom of the tank. The above abalone grows 20mm or more, sea cucumbers grow 3 ~ 5cm or more can be shipped to the general farm as a seedling.

As described above, only one embodiment of the present invention may be mentioned various methods for producing sea cucumber seedlings and abalone seedlings together. For example, the above method may be performed by exposure to sunlight to form diatoms on the tank's wavepan, but may be performed by darkening the whole process. Although diatoms are used as food for sea cucumbers and abalone seedlings, large quantities of copepods, which feed on diatoms, are inevitable, thus blocking the light and darkening the inside of the farm, thereby suppressing the large-scale generation of copepods, such as pests, that occur on scallops. You can do it. In this case, abalone feeds the feed, but may also use the feces of abalone as food for sea cucumbers.

In addition, it can be used more efficiently by darkening only a part of the process. For example, the treatment of dark abalone and sea cucumber seedlings until dark, and after the attachment of abalone and sea cucumber seedlings, sea cucumber abalone may grow in a period of time after exposure to sunlight to generate diatoms, leading to efficient feeding. . In this case, if the sea cucumber and abalone species grow to some extent, they are less susceptible to copepods.

In the above-described process, the sea cucumbers and abalone larvae were separated and bred until attachment time, but not limited thereto, and mixed breeding may be sufficient. In this case, it is possible to control the timing of mixing into the tank based on the timing of attachment of sea cucumber seedlings with longer attachment time. This is because abalone larvae have a shorter time to attachment and do not eat.

Apparently, there are many different ways to modify these embodiments while remaining within the scope of the claims. In other words, there may be many other ways in which the invention may be practiced without departing from the scope of the following claims.
