Depths below 200 m and deep seas have similar levels of salinity (NaCl) and most minerals, as shown in Table 1, "Analysis of Ocean Depth and Surface Waters". Phosphoric acid, silicon), viable cell number, and water temperature are significantly different.

Deep sea water has the following characteristics compared to surface water.

1. Low temperature safety

While the surface temperature of surface seawater fluctuates greatly with the seasons, deep ocean waters are stable at low temperatures without changing the water temperature with the seasons.

In particular, deep sea waters in the East Sea of Korea settled by dense differences in cold seawater that melted drift ice in the Sea of Okhotsk, off the coast of Vladivostok between Ostrov Sakhalin and Hokkaido. As the deep water flowed in and blocked the Japanese archipelago, the flow was slow. At 300m or less, the water temperature was 1 ~ 2 ℃ throughout the year, compared to the deep sea water of Muroto in Kouchi Prefecture on the Hawaiian and Japanese Pacific coasts. There is a characteristic low about -11 degreeC.

2. Cleanliness

Because it is deep, it is difficult to receive pollution from river water and air on land, and there are few chemicals, pollutants and bacteria.

① physical cleanliness

Physical cleanliness is said to include less suspended matter and suspended matter. Deep sea water has less suspended solids than surface seawater.

② biological cleanliness

The biggest problem in the intake of seawater is the propagation of adherent organisms. In general, in the surface seawater intake system, the adherent organisms propagate in the intake pipe, and the resistance of the pipe increases and it becomes impossible to take in water. The total number of viable bacteria, such as (pathogenic) microorganisms, chlorella, etc., is small, from one tenth to one hundredth of surface water.

③ chemical cleanliness

Since deep seawater does not mix with contaminated surface waters, it is not contaminated with so-called environmental pollutants such as dioxins, PCBs, organic chlorine compounds, and organic tin.

3. eutrophicity

The deep ocean water contains about 5 to 10 times more inorganic nutrients than nitrogen, phosphorus, and silicic acid, which are the nutrient sources of phytoplankton (mainly diatoms, microscopic single-celled plants with chlorophyll), which are the source of sea life compared to surface seawater. There is a characteristic that abundant salt is contained.

At depths of 150 m or less, the amount of light is less than 1%, and at further depths, phytoplankton are not capable of photosynthesis, so nutrients are not consumed by phytoplankton but sink and accumulate in the lower layers, resulting in high concentrations of inorganic nutrients.

4. Characteristics of minerals

Sea water contains more than 70 kinds of elements, and deep sea water also has such a variety of elements.

Although there are many important elements necessary for the growth of animals and plants, they are necessary, but mineral traces that contain very small amounts of deeply related to human health, such as copper and zinc, essential trace elements that are harmful to intake in large quantities. There is a good character.

5. Aging

Deep sea water has a lower pH than surface sea water (around pH 7.8), low organic matter content, and deep sea water separates from surface sea water, resulting in small clusters of small water molecules for many years under low pressure and high pressure. Micro-clustered water (小集團 化) is the water quality is stable.

The number of populations of water molecules is measured indirectly by measuring the value of the nuclear magnetic resonance (NMR) ¹⁷ O-NMR half-width.

In general, in the case of river water and tap water, the half-height width of nuclear magnetic resonance ¹⁷ O-NMR is 130-150∼, whereas in deep sea water, the half-width of nuclear magnetic resonance ¹⁷ O-NMR is 70-80㎐.

And the value of 1/10 of the water nuclear magnetic resonance ¹⁷ O-NMR half-width value (㎐) of the groups known as the number of water molecules, nuclear magnetic resonance ¹⁷ O-NMR half-width is 130~150㎐ of water, such as river water or tap water 13-15 water molecules are clustered by hydrogen bond, and the large water is called bound water, whereas nuclear magnetic resonance ¹⁷ O-NMR Water with a small half-width and low population of water molecules is called microclustered water.

In the present invention, using the above-described deep seawater and surface seawater characteristics, the method of aquaculture algae such as cold water kelp, seaweed, rhubarb, black persimmon, mabanban, ,, cheontae, blue sea, auditory and abalone to feed these algae After shelling shellfish such as seashells, show how to farm fish such as sea cucumbers, crabs, flounder, and flounder.

Shellfish such as abalone and turban shell are typical herbivorous gastropods, and when they are young they eat seaweeds or rocks that adhere to rocks, and when they are adults, their main foods are seaweed, kelp, rhubarb, Eating brown algae such as Ecklonia cava, Mabanban, and 톳 (鹿尾 菜) and green algae such as brown algae, green algae such as orthodox brown algae, and algae such as red algae.

The growth conditions of seaweeds vary slightly depending on the type, but in the case of kelp, the main food for abalone or conch, young leaves emerge from December to March in the country of origin and grow until July with water temperature of 12-13 ℃. It is withered when it is over, and grows actively when the water temperature falls below 10 ℃. It is known to grow well in the northern coast of North Korea, Hamgyongnam-do and North Hamgyong-do. It is mainly distributed in the Pacific coast of Hokkaido, Tohoku, Japan, Kamchatka Pen, and Sakhalin Island. In the case of artificial culture of kelp, the water temperature is 5 ~ 10 ℃. It should be adjusted so that it enters the kelp tank.

Most brown algae, such as seaweed, rhubarb, Ecklonia cava, moss, and shellfish, are algae algae that grow from early autumn to spring like kelp, so the water temperature grows below 10 ° C. do.

Sea cucumbers belong to the sea cucumber river, buried under the sea or in the sand mud. The appetite is vigorous and active under the water temperature of 17 ℃ and below. When it comes to sleep.

Sea cucumber food is an omnivorous, herbivorous tentacle that feeds on the mud under the sea and eats small creatures in the sand. It eats algae, and the red and red ginseng are the same species. They grow by eating attached red algae.

The sea urchin's appetite differs depending on the type, but it is said to eat anything because it is omnivorous to eat aquatic animals that live on seaweeds and rocks, but stocks grow by eating seaweed such as kelp and mabanban.

Since sea cucumbers and sea urchins are in competition with food, not abalone and natural enemies, they can be fed while feeding seaweeds.

Yellow flounder (Barfin flounder) is a saltwater fish of the flatfish of the flounder, 50-60cm in total length, dark gray on the lateral side, orange-yellow on the lateral side, and female yellow White, black stripes on dorsal, hip and tail fins, dark brown and yellowish yellow on the side of the eyes, and rough in pine bark in Japan. ) It is tasted and is considered as the best fish among flounder with tiger flounder with tiger pattern on its chest.

The growth temperature of yellow flounder is around 14 ° C, and the Korean Wave is less than 100m in the East Sea, Japan, Hokkaido, Kuril Is, Ostrov Sakhalin and Sea of Okhotsk. It is a cold-water fish that lives on sand or mud bottoms and eats worms, shellfish, shrimps and zooplankton. It is mainly caught in winter.

Divalent and trivalent iron ions are indispensable to plants for photosynthesis and are stable supplies to the roots for long periods of time. They are substances that assist the plant's self-growth by adding magnesium ions and calcium ions. Promote growth, increase yields, and improve sugar and taste effects.

Since divalent and trivalent iron ions have a magnetic field and magnetic (magnetic fluid), according to the law of electromagnetic induction, when negative (-) electrons, which have a force from a magnetic field, come into contact with water, they become negative ions to prevent oxidation of water. In addition, the oxidation of water has a great effect on the growth of animals and plants.

Water molecules containing divalent and trivalent iron ions at the origin and future of the life sciences of Professor Yamashita Shoji of the Nagoya University Faculty of Agriculture. Hydrogen bonds are partially cleaved and treated with small groups of water (called "π-water"), which serve as a catalyst for plants to improve absorption of nutrients. Turned out to be.

There is a saying, "Forests are lovers of the sea." In summary, if there are woodlands upstream of the river, deciduous leaves and other animal excretion and carcasses accumulate in the surface layer, and they mix with the soil, Corrosive substances are produced by this, which contains abundant nitrogen, phosphorus, iron and metal ions.

Originally iron is contained in soil or rock and is carried by rain and in water in the form of particle iron in water, but as it is, the particles are so large that they cannot pass through the cell membranes of plants and are not absorbed, but this corrosion When fuvic acid and iron ions contained in the material are combined, it is called "iron fulvate".

In the form of ferrous phosphate salts, the size of the particles is smaller, so that the plants can absorb them directly. When the ferric salts enter the sea, they play an important role in the growth of phytoplankton and seaweeds off the coast.

Thanks to the ferrous salts of this corrosive substance, it is effective for the reproduction and growth of living things such as seaweed kelp and fish and shellfish.

And the corrosive soils in the magnetized magnetite region were found to be more effective. In the case of rock water in the magnetized magnetite region, it was found that the magnetohydrodynamics (MHD) This is because water (magnetic fluid) containing trivalent iron ions passes through the magnetic field of magnetized magnetite, and the water molecules and the iron ions are magnetized to cluster the clusters.

Therefore, in the present invention, a solution in which the magnetized magnetite is dissolved in concentrated hydrochloric acid solution and a corrosive substance (also referred to as peat or peat) is alkali treated to pH 14 or higher, and then the acid is treated with hydrochloric acid solution to pH 2 or lower to precipitate the humic acid (Humic). The ferrous salt solution produced in response to the Fulvic acid extract from which the acid portion was removed is a magnetic field of a permanent magnet or an electromagnet having a magnetic flux density of 12,000 Gauss or higher. The solution is fed to the algae aquaculture tank by supplying the magnetized fulbrate solution with a flow rate of 2 to 10 m / sec.

At this time, if the concentration of suspended solids in the deep sea water taken is 50 mg / l or less, the filtration step may be omitted.

II. Steps to grow primary seaweed

In the first algae aquaculture process, kelp and seaweed are mainly farmed, and the algae grown in the first algae aquaculture tank (8) are dark in color, thick, and excellent in quality, so the main purpose is to commercialize the seaweed itself after processing. It can also be used as feed for abalone, hermit, sea cucumber or sea urchin.

The rate of supply of deep seawater and surface seawater to the temperature control tank 7 is supplied to the first seaweed culture tank 8 such that the temperature of the temperature indicator (TI) is 5 to 10 ° C. suitable for the growth of kelp and seaweed. In the meantime, the concentration of dissolved oxygen is intermittently passed through the air diffuser 11 to the air in the air from the blower 13 so that the dissolved oxygen indicator (DOI) is maintained in the range of 5 to 9 mg / l. In order to further improve the culture efficiency of the seaweeds, the magnetized iron fulvate solution was supplied to the first seaweed culture tank 8 with a total iron content in the range of 0.05 to 0.3 mg / l, and the discharged water. The fish are sent to a warming process for fish farming to produce seaweed such as seaweed or kelp.

When the flow rate which flows in here is made large and the density | concentration of dissolved oxygen of the 1st seaweed culture tank 8 is maintained in the range of 5-9 mg / l, it is not necessary to supply air from the blower 13 and to aeration.

The kelp or seaweed cultured here is processed and commercialized or used as food for abalone, seashell, sea cucumber or sea urchin.

The magnetized ferric phosphate salt was dissolved in an alkali (Alkali) solution (3-10 wt% NaOH) in the corrosive substance (peat) and dissolved while adjusting the pH to 14 or more to 3-10 wt% Hydrochloric acid (HCl) solution was magnetized to a magnetic flux density of 50 to 500 Gauss in a solution of Fulvic acid in which the precipitated substance was removed by adding a pH in the range of 1-2. ), Dissolved in magnetite or 4, iron trioxide (Fe ₃ O ₄ ) in an aqueous solution of 3-10 wt% hydrochloric acid, with a weight ratio of inorganic to organic in the range of 0.4 to 1.0, iron fulvate. Is supplied to the ferrous salt storage tank 14, and the permanent magnet or electromagnet magnetized to have a flux density of 12,000 to 15,000 gauss by the ferrous salt transfer pump 15 is made of synthetic resin. PVC, PE, styrene resins, etc.), ebonite, FRP, Bakelite, etc. The magnetic field of the magnetizer 16 which forms a magnetic field inside the coil when an AC or DC low voltage in the range of 0.5 to 5 Volts is applied to the coil wound around the pipe. The magnetized fulbrate salt is prepared by carrying out magnetization while conveying the ferric phosphate solution magnetized and passed through the furnace at a flow rate of 2 to 10 m / sec for 10 to 60 minutes to the fulbrate salt storage tank 14.

The structure of the first seaweed culture tank 8 is good if it is a concrete structure having a depth of 5 to 10 m, but the water depth is not particularly limited, and the bottom bottom portion is filled with sand 9 to 20 to 30 cm. V), and then fill the top of it with natural rock 10 to 30-40 cm thick.

III. Steps to Fish

1) warming process

The discharged water of 5-10 degreeC discharged from the 1st seaweed culture tank 8 is sent to a heating process, and it adjusts to 15-20 degreeC which is the temperature suitable for abalone or turban growth.

The temperature of the seawater supplied to the shellfish culture tank 17 in the heating step is adjusted to 15 to 20 ° C., which is suitable for abalone or turban growth, and the temperature adjustment method is as follows according to the temperature of the surface seawater. Adjust

① When the surface water temperature is above 20 ℃

 The surface seawater is mixed with the discharged water of 5 to 10 ° C. discharged from the first seaweed culture tank 8 to a temperature in the range of 15 to 20 ° C. and supplied to the shellfish culture tank 17, wherein the first seaweed culture tank 8 Surplus discharged water discharged from) is sent to the water temperature adjusting tank 21 at the front end of the second seaweed culture tank 22.

② When the surface water temperature is 15-20 ℃

 When the surface seawater temperature is 15 to 20 ° C, the surface seawater is supplied to the shellfish culture tank 17 without heating only the surface seawater, and the discharged water at 5 to 10 ° C discharged from the first seaweed culture tank 8 removes the entire amount. It is sent to the water temperature adjustment tank 21 of the front end of 2 seaweed culture tank 22.

③ When the surface water temperature is 10 ~ 15 ℃

Only the surface seawater is heated to 15 ° C for energy saving and supplied to the shellfish culture tank 17. At this time, the discharged water of 5 to 10 ° C discharged from the first seaweed culture tank 8 is entirely the second seaweed culture tank. (22) It is sent to the water temperature adjustment tank 21 of a front end.

At this time, the heating method is heated by hot water or steam using a heat exchanger, or heated by an electric heating coil (Heating coil).

④ When the surface water temperature is below 10 ℃

When the surface temperature of the seawater is 10 ° C or lower, the supply of the surface seawater is stopped in the heating process, and the effluent water discharged from the second seaweed culture tank 22 is removed from the solids in the purification process. The water temperature of the seawater flowing into the shellfish aquaculture tank 17 is warmed to 15 ° C while being returned in the range of 30-50% of the total flow rate flowing into the shell.

At this time, the heating method is the same as the heating method of the above ③.

2) Aquaculture process of shellfish

When the seawater whose water temperature is adjusted to 15 to 20 ° C. flows into the shellfish aquaculture tank 17, the air in the air is blown from the blower 13 to the dissolved oxygen concentration of the dissolved oxygen indicator (DOI) of 5 to 9 mg /. Kelp, seaweed, and rhubarb cultured in the first seaweed culture tank (8) and the second seaweed culture tank (22) while feeding and aeration to the air conditioner (11) so as to remain in the l range. Feeds one or more species of seaweed in gulfweed, seaweed, green onion, auditory, or cheontae, and the discharged water is discharged from sea cucumber, sea urchin or sea urchin. Send abalone or turban to Joe (19).

In this case, when the flow rate flowing in is increased and the concentration of dissolved oxygen in the shellfish culture tank 17 is maintained in the range of 5 to 9 mg / l, it is not necessary to supply air from the blower 13 to aeration.

The shellfish culture tank 17 has a water depth of 1-10 m, but the depth of the shellfish is not particularly limited, and the bottom bottom portion of the shellfish culture tank 17, as in the first seaweed culture tank 8, has 20 to 20 m. It is filled with 30 cm, and the rock 10 of natural stone is filled with thickness of 30-40 cm.

3) Sea cucumber or sea urchin farming process

Sea cucumber is a omnivorous animal that eats small creatures in the sand mud with tentacles in its mouth and eats algae. It can be fed by abalone or turban dung, and eats algae like abalone or turban The feed supplies algae such as seaweed, seaweed, rhubarb, maize, shellfish, greens, hearing or sackcloth, which are the food for abalone or conch.

And the sea cucumber has a strong appetite and active exercise at water temperature below 17 ℃, stop eating when it is above 17 ℃, and when the water temperature is above 25 ℃ in summer, sleep during the summer and stop feeding, so the water temperature is 12 ～ It is preferable to adjust to 16 degreeC.

The food of sea urchin is slightly different depending on the type, but it is a omnivorous species that mainly eats seaweed or aquatic animals that live on rocks. It is similar to sea cucumber, and its growth temperature is active at 12 ~ 16 ℃ similar to sea cucumber.

Therefore, sea urchins and sea urchins are similar in food type and growth temperature, and are not competing in natural food relations.

When the discharged water of 15-20 ° C from the shellfish culture tank 17 flows into the sea cucumber, sea urchin or sea urchin culture tank 19, it is supplied with low-temperature deep sea water to adjust the water temperature to 12-16 ° C. The first marine algae culture is performed by supplying air in the air from the blower 13 to the air diffuser 11 so that the dissolved oxygen concentration in the dissolved oxygen indicator (DOI) in (19) is maintained in the range of 5 to 9 mg / l. One or more types of seaweeds from kelp, seaweed, rhubarb, rhubarb, maize, scallop, green, auditory, or taekwondo are supplied as food, and the discharged water is discharged from the fish farming tank (2). 20) to farm sea cucumbers, sea urchins or sea urchins.

In this case, when the flow rate is increased and the concentration of dissolved oxygen in the sea cucumber, sea urchin or sea urchin culture tank 19 is maintained in the range of 5 to 9 mg / l, it is not necessary to supply air from the blower 13 to perform aeration. .

Sea cucumber, sea urchin or sea urchin culture tank (19), the depth of the 1-10m concrete structure is acceptable, but the water depth is not particularly limited, the bottom portion of the sand (9) is filled with 30 ~ 60㎝.

4) Fish farming process

In the fish farming process, the types of feed and the conditions for breeding differ according to the type of fish, but in the present invention, flounders (flounders) and flounder (high-value fish species), which can be economically farmed using low-temperature deep sea water, can be grown economically. Yellow flounder: 松皮).

Yellow flounder, which is the most delicious among the flounder with pan flounder, has a low water temperature of 14 ° C or less of 100m or less in the East Sea of Korea, Kuril Is, Ostrov Sakhalin, Sea of Okhotsk, etc. Live on sandy or muddy ground.

Flounders and flounders usually live on the sandy bottom of the sea, which does not exceed 200 m in depth, while they eat small shrimps and other fishes while they are young, and they eat crustaceans, mollusks, or small fish.

In the present invention, the fish culture is dissolved oxygen indicator while adjusting to 10 ~ 14 ℃ by injecting deep sea water when 12 ~ 16 ℃ discharge water of the sea cucumber, sea urchin or sea urchin culture tank (19) flows into the fish culture tank (20) Supplying the mixed feed of flounder or flounder sold in the market while supplying air in the air from the blower 13 to the diffuser 11 so that the concentration of dissolved oxygen of DOI is maintained in the range of 5-9 mg / l. And, the discharged discharged water is sent to the water temperature control tank 21 in front of the second seaweed culture tank 22 to culture the flounder and flounder fish.

In this case, when the flow rate flowing in is increased and the concentration of dissolved oxygen in the fish farming tank 20 is maintained in the range of 5 to 9 mg / l, it is not necessary to supply air from the blower 13 to aeration.

The fish culture tank 20 has a water depth of 1 to 10 m, but the water depth is not particularly limited, and the bottom bottom portion of the fish tank 20 as shown in the first seaweed culture tank 8 is 20-20. It is filled with 30 cm, and the rock 10 of natural stone is filled with thickness of 30-40 cm.

Ⅳ. Steps to Aquaculture Secondary Seaweeds

The algae farmed in the second seaweed farming process has lower nutrient concentration than the algae farmed in the first seaweed farming process, so the color and quality of the seaweed are slightly lowered, but the growth is slightly reduced. Can be used sufficiently.

In the second seaweed farming process, the seaweeds are mixed with seaweeds such as rhubarb, maize, sesame seeds, greens, greens or blue sea, which can be used as feed for abalone, seashells, sea cucumbers and sea urchins, in addition to seaweed and seaweed.

Compared to the case of supplying single seaweed to abalone, seashell, sea cucumber or sea urchin, the quality of seaweed mixed with two or more kinds of seaweed, seaweed, rhubarb, mabanban, sesame, green, auditory or taetae Because of its superiority, it is desirable to feed a variety of mixed seaweeds rather than single seaweeds.

Effluent water with a water temperature of 10 to 14 ° C. in the fish culture tank 20 and discharge water from the first marine algae culture tank 8 and return water from which suspended solids (SS) are removed in the purification process are introduced. When the deep sea water is adjusted to a temperature of 5-10 ° C. suitable for growing algae, the deep sea water is supplied to the second seaweed culture tank 22, and the dissolved oxygen concentration of the dissolved oxygen indicator (DOI) In order to maintain the concentration in the range of 5 to 9 mg / L, the air in the air is intermittently supplied from the blower 13 through the air diffuser 11, and the ferrous salt of fulbrate, which has been magnetized in order to further improve the aquaculture efficiency of seaweeds (Iron) fulvate solution is supplied to maintain the total iron content in the range 0.05 ~ 0.3mg / ℓ, and the discharged discharged water is sent to the purification process, which can be used to feed the abalone, seashell, sea cucumber or sea urchin, seaweed, kelp, rhubarb, Maternity, heat, blue, hearing Or aquatic algae.

Here, seaweeds from seaweed, seaweed, rhubarb, maban, 톳, blue, auditory or taetae are used as food for abalone, conch, sea cucumber or sea urchin.

The structure of the second seaweed culture tank 22 is the same as that of the first seaweed culture tank 8, but if the concrete structure has a depth of 1 to 10 m, the depth is not particularly limited. As in (8), sand 9 is filled to 20 to 30 cm, and rock 10 of natural stone is filled to a thickness of 30 to 40 cm.

The purification process uses a flotation tank that removes suspended solids from sewage and wastewater treatment, or a settling tank that precipitates and removes activated sludge. After the concentration is 20-50 mg / l, it is sent to the discharge tank 23 and discharged to the sea, and some are returned to the water temperature adjusting tank 21 of the pre-fish farming stage and the pre-second seaweed farming stage. do.

The first seaweed culture tank (8), shellfish culture tank (17), sea cucumber, sea urchin or sea urchin culture tank (19), the sand (9) to fill the fish culture tank 20 of the present invention is effective diameter (效 徑) It is acceptable to use 0.3 to 0.5 mm and equal coefficient of 2.0 or less, and the rock 10 may use a size of 200 to 1,000 mm Φ which is mined in a natural state, but the size is not limited.

Air blower used to adjust the concentration of dissolved oxygen in the first seaweed culture tank (8), shellfish culture tank (17), sea cucumber, sea urchin or sea urchin culture tank (19), and fish culture tank (20) ) Pressure is determined by considering static head and friction head according to the depth of each tank, and type of blower is good to use volumetric roots blower. However, depending on the flow rate and the supply pressure, turbo blower, radial fan blower, multibalde fan blower, limit loaded fan blower, airfoil fan Centrifugal blowers such as blowers may be used.

Example 1

The kelp is attached to the base 150 (40 cm × 40 cm) seawater adjusted to 7-8 ° C by mixing deep ocean water with a water temperature of 3.2 ° C. and surface seawater with a water temperature of 16-18 ° C. It was placed in 10 tanks of 3m × 1m × 1m (depth), and the concentration of dissolved oxygen in the tank was inflated with 6-7mg / l air to blow the kelp while intermittently aeration. It is possible to stably produce 30 kg of kelp per month.

Example 2

A seashell filled with 40 cm of sand with an effective diameter of 0.45 mm and an equivalent coefficient of 1.65 with a seaweed of tangle grown in Example 1, with an average length of 40 mm in length. ) And 200 tanks were injected into 10 tanks and surface seawater with a water temperature of 16 to 18 ° C was incubated for 1 month while injecting dissolved oxygen at a flow rate of 6 to 8 mg / l. Cultured up to mm.

Comparative Example 1

10 pieces of abalone flocks with an average diameter of 40 mm in a tank filled with 40 cm of sand with an effective diameter of 0.45 mm and an equal coefficient of 1.65, in the same 1 m x 1 m x 1 m (depth) as in Example 2 Injected into the tank and infused with superficial seawater with a water temperature of 16-18 ° C. at a flow rate of 6-8 mg / l of dissolved oxygen, harvested in winter and fed salted kelp for one month. The squares were grown to an average of 64 mm.

As shown in Example 1 above, the kelp was stably cultured even in the early summer when the surface temperature of the seawater was 16 to 18 ° C. The growth rate of abalone was improved by 20% when compared to Comparative Example 1, which was fed with salted kelp.

This increase in growth rate is estimated to have been fed by feeding fresh food.

As described above, the present invention, in particular, in the method of farming abalone, which is an expensive shellfish, was harvested in winter without seaweeds such as kelp or seaweed, which is fed in summer, and then fed in summer. Compared to this, the growth efficiency is improved, and it is expected to be widely used in aquaculture since it is possible to grow high-quality fish such as sea cucumber, sea urchin, flounder or flounder by using the discharged water discharged here.
