Description

Octopus raising apparatus and raising method using the same {Aquaculture method and facility for octopus.}

The present invention installs a high-density and easy-to-follow octopus rearing device in an onshore aquaculture tank and raises it for a certain period using deep sea water. It relates to an octopus breeding device that can contribute to stabilization and a breeding method using the same.

In general, cephalopods include octopus, octopus, and squid. In particular, octopus is a perennial animal belonging to the Octopus family, and is widely distributed in the northern part of the eastern Pacific such as Korea, Japan, Alaska, and California in North America. The octopus is a coastal benthic species and lives in crevices or holes in rocks from the Azoic to 50m. Octopuses live in crevices of rocks or in burrows dug in mud, and spread their arms out to catch prey.

In Korea, it mainly inhabits the southern and eastern coasts, and goes through the spawning season from early summer to early autumn. The spawning grounds are in the recesses between the reefs or in the hollows, even if they are made of sand or mud, and they spawn inside. It takes 3 or 4 months to become an adult, and the growth is relatively fast.

Octopus contains abundant taurine, which effectively suppresses triglycerides and cholesterol in the blood, aids in liver detoxification, and is effective in recovering from fatigue. Octopuses are marine organisms that can survive for a certain period of time without food intake under a physiologically certain temperature. .

In addition, octopus has a market characteristic in which consumption increases rapidly around a certain period, such as holidays, due to the nature of domestic consumption, so its price is also classified as a fishery product with a high ups and downs. From the seller's point of view, there is a problem of securing a stable quantity of octopus throughout the year, and although a market situation where consumers can purchase octopus all year round at a low price must be established, it is impossible to meet consumer demand due to fluctuations in production volume or price fluctuations. There are things that don't exist.

The solution to this problem is a problem that can be solved to some extent if the production of octopus can be controlled, but it is impossible to artificially control the catch of octopus. However, if the distribution problem of caught octopus can be solved to some extent, stable market formation can be maintained for sellers and consumers.

In the end, it is most important to establish a distribution structure that can meet the market demand by raising octopus during a period when large quantities are temporarily caught or consumption is reduced for a certain period of time.

Holding is the temporary storage of live, easy-flying animals in an appropriate facility. Scientific livestock technology is to increase the storage density of living organisms in a narrow space, and the development of livestock technology is important in terms of operation of the fish farm.

Figure 1 shows a conventional cephalopod livestock farm. The livestock farming method using the octopus breeding net does not supply food, but accommodates one octopus in a net formed of a mesh, and there is a lot of inconvenience in collecting dead individuals and supplying food.

Accordingly, Korean Patent No. 10-1606630 of the octopus discloses a cephalopod prefabricated device that can take into account the tactility of the octopus and prevent pitting. The configuration of a device capable of raising octopuses with the octopus is not disclosed, showing a difference.

On the other hand, deep sea water refers to seawater distributed in the deep sea with a depth of 200 m or more. In general, up to 200m below the surface where light can reach is called the shallow sea, and above it is called the deep sea. The shallow sea is a production layer that is affected by the food chain, and the deep sea is a mitosis layer because only organic matter decomposition proceeds mainly.

In the case of seawater, the specific heat is greater than that of solids or most liquids, so there is little change in water temperature. The temperature continues to decrease, and when the water depth exceeds 1000m, it maintains a stable low temperature of about 5℃. This is called low-temperature stability.

The characteristics of deep ocean water are low temperature stability and deep water, so unlike surface water, there are very few environmental pollutants, excellent physical, biological and chemical cleanliness, and eutrophication containing a lot of various minerals.

With the development of deep-sea water intake technology, the use of deep-sea water is also diversifying in the fishery field, health, beauty, medical care, and power generation. In particular, in the aquaculture field, the temperature is controlled by mixing deep water and surface water appropriately, and deep-sea fish such as dodt bream, red coral of the southern deep sea, halibut, blue flounder, and sardines, as well as cold-water fish species such as Atlantic salmon, silver salmon, and sardine trout starting breeding.

Therefore, the present invention provides a stable supply of octopus without changes in fish weight and survival rate and food quality by installing a high-density and easy-to-follow livestock breeding device in a land-based aquaculture tank and rearing it for a certain period using deep sea water. We aim to provide a method that can contribute to market stabilization.

The livestock farming method using the octopus rearing device does not supply food, but accommodates one octopus in a net formed of a mesh, and there is a lot of inconvenience in the collection of dead individuals and the feeding operation. The present invention installs a high-density, easy-to-follow livestock raising device in a land-based aquaculture tank and raises it for a certain period using deep sea water, thereby stabilizing the market through stable supply of octopus without changes in fish weight and survival rate and food quality. We want to provide you with a way to contribute.

Hereinafter, the octopus raising apparatus of the present invention and the accompanying drawings related to the raising method using the same will be described in detail as follows.

Figure 2 shows a schematic diagram of a culture method using the octopus raising apparatus of the present invention. The method of aquaculture using the octopus livestock farming apparatus of the present invention includes the steps of: (A) storing the deep sea water by taking it into an onshore breeding tank, controlling the temperature; stocking the octopus in the octopus breeding apparatus and storing the octopus breeding apparatus in the land breeding tank (b); The step (c) of cultivating the stored octopus for a certain period may be performed.

(A) Deep sea water intake and storage stage

Step (a) of the present invention includes taking the deep-sea water, which is seawater distributed at a depth of 200 m or more, adjusting the temperature to 7 to 15° C. in a temperature control tank, and moving it to a land breeding tank and storing it.

The deep-sea water referred to in the present invention is the seawater of the deep sea that is distributed at a depth of 200 m or more and generally maintains a water temperature of 4° C. or less. Unlike surface seawater, deep ocean water does not receive sunlight, so plankton and living organisms do not proliferate. Due to the difference, it does not mix with the surface seawater and there are no contaminants present in the surface seawater. ), mineral balance characteristics, aging characteristics, etc.

As is known, the deep-sea water intake is installed so that the upper water level of the deep-sea water collection tank is below sea level, and the deep-sea water intake pipe is installed up to the seabed at a depth of 200 m or less. After adjusting the temperature to 7 to 15 ℃ in the control tank can be supplied to the land breeding tank.

(B) Storage stage of octopus raising device

Step (b) of the present invention includes stocking the livestock octopus into the octopus accommodating space of the octopus raising device, and then storing it in the land culture tank of step (a). Figure 3 shows a perspective view of the octopus breeding apparatus of the present invention, and Figure 4 shows a photograph of the front part of the breeding apparatus. The octopus rearing apparatus of the present invention includes a receiving frame 10 having a rectangular parallelepiped shape having an internal space; One or more partition walls are formed in the accommodating frame inner space to form a plurality of octopus accommodating spaces; An entrance 20 is formed on the side of the single octopus accommodation space so that the octopus can be stocked and fed; A lid 30 that is formed so as to be able to open and close corresponding to the doorway is installed.

The accommodating frame 10 of the present invention is made of a plastic material that is strong in seawater and is easy to process, and may preferably be formed of polyvinyl chloride (PVC). A plurality of polygonal seawater distribution holes are formed on the side of the accommodation frame so that seawater can enter and exit the inner space and sludge including feed residues and excrement can be discharged.

The doorway 30 has a protrusion so that it can be coupled with the lid, and a screw thread is formed on the side of the protrusion. The structure in which the doorway and the lid of the present invention are coupled and fixed can be formed to open and close by a screw-type turning method or a one-touch method.

As an embodiment according to the present invention, the lid is formed to be opened and closed by cutting the thread of the PVC socket and opening and closing the door in a one-touch shape, so that the operation is easier and the manufacturing process and cost can be reduced.

In the case of the one-touch structure, the doorway is formed on the upper part of the accommodation frame, and in the deep-sea water culture step to be described later, even if the manager does not reach the low temperature breeding water, it can be opened and closed to check the supply of food and the state of the accommodated octopus.

The accommodating frame is provided with an internal space for cultivating a cultured octopus therein. At least one partition wall is installed in the inner space in a horizontal or vertical direction, so that a plurality of octopus accommodating spaces are formed in the inner space to independently store the octopus, thereby preventing the octopus from being formalized.

The entrance is installed on the side wall of the octopus accommodation space so that storage and food supply can be made individually. According to an embodiment of the present invention, a partition wall is installed in the vertical direction inside the accommodating frame to form two octopus accommodating spaces, and an entrance is formed on the sidewall of each octopus accommodating space.

As shown in Figure 5, the present invention can be stored in a water tank by loading a single octopus rearing device up and down. In addition, as shown in Fig. 6, by connecting a plurality of up and down hoisting devices in the horizontal direction, it is possible to store them at high density in the aquaculture tank, thereby increasing the aquaculture efficiency.

(C) Octopus rearing stage

Step (c) of the present invention includes the step of cultivating the octopus rearing device that has undergone the step (b) in an onshore aquaculture tank for more than 60 days.

Hereinafter, an experimental example confirming the survival of the octopus according to the breeding method using the octopus rearing apparatus of the present invention is as follows. In the experimental example of the present invention, octopuses were raised at 8 °C and 12 °C, respectively, at the water temperature of the deep sea water stored in the land breeding tank, and the condition was observed and measured while raising for 60 days.

7 shows the survival results of the octopus according to the rearing of the octopus at 8°C and 12°C, respectively. As shown in the graph, although there is a difference depending on the water temperature, the survival rate of the octopus was confirmed to be 80-90%.

8 is a graph showing the growth results of the octopus according to the livestock quantity for each water temperature of 8 ℃ and 12 ℃. As shown in the graph, although there is a difference depending on the water temperature, it was confirmed that the growth rate of the octopus was 20-40%.

9 shows the results of raising octopuses by individual weight using deep sea water. Looking at the experimental results of the growth rate and survival rate of the octopus according to the method of the present invention, it can be seen that the wet weight change results after 60 days of the livestock experiment by individual wet weight show faster growth in individuals of 1.5 kg or more than small individuals. have.

In the case of the 0.5 kg wet weight octopus, the individual with the highest circulation, it grew faster when the water temperature was 12℃ than when it was 8℃.

Therefore, although there were differences depending on the water temperature and individual size, the overall survival rate of octopus was 80-90% and the growth rate of octopus was 20-40%, indicating relatively good growth and survival rates.

The present invention is aimed at stabilizing the market through stable supply of octopus without major changes in the period setting and quality of octopus breeding by increasing the growth rate and marketability of octopus compared to existing technologies by developing an octopus breeding device, as well as establishing a distribution structure to increase the income of fishermen. There is an industrial applicability that can be contributed.
