Description

Eco-friendly mixed farming method using tributary trout fish farm {The combinated farming way of fish}

The present invention relates to a method for complex farming with benthic organisms in a trout farm, and to an environment-friendly complex farming method capable of complex farming of trout and abalone or sea cucumbers overcoming sunshade stress.

Trout is cold-water and inhabits only cold, clean first-grade water. After hatching, they inhabit the river and live in the sea, then become mothers, return to the river, lay eggs and end their lives. Naturally, salmon have a physiological adaptation function to seawater, so they can be nurtured in the sea after a certain period of pure water purification. Due to these characteristics, it is naturally possible to use trout for seawater, but seawater order must be performed for the practice of seawater trout farming.

The seawater netting process is a step in which fish jersey is moved into a breeding tank and the salinity of the water in the breeding tank is continuously increased by using the ability to adjust the osmotic pressure of the fish so as to be able to survive at the salinity corresponding to the seawater.

In the case of freshwater fish, the body fluid has a higher salinity than environmental water, and the water continues to penetrate into the body through gills, digestive organs, and epidermis, and in order to maintain the proper amount of water in the body, dilute urine in the kidneys and release it in large quantities. Maintains moisture in the body. At this time, monovalent ions such as Na + discharged with urine are absorbed by tissue epithelium such as kidney and bladder, and salts contained in food are absorbed by intestinal epithelial cells. In addition, there are freshwater salt cells in the new side of the gills, which absorb salts through the action of the proton ATPase enzyme on the vacuole to maintain the salinity of body fluids. In the case of seawater fish, since the body fluid has a lower salinity than environmental water, a large amount of seawater is introduced into the body to absorb physiological dehydration to absorb moisture from the intestine.

Trout belonging to the salmon species biologically hatch from freshwater and grows as a larvae, and when it comes to the Smolt period, it gradually undergoes salinity in brackish water and undergoes seawater domestication. Therefore, it is necessary to supply fresh water from the land tank and riders from the stockyard installed in the land or sea space, and sea water from the sea edge.

Since moving trout that is used to fresh water to the sea is a significant burden on the fish, it is appropriate to breed the fish in a state that is healthy and can withstand changes in the environment and then move to sea water. After being raised in (athletic), about a year or so, the body weight is about 200 to 350 g.

Therefore, in a typical inland water farm, 200g or so medium-sized fish are purchased, and after a certain period of time, seawater is placed, and then placed in a marine cage or onshore tank farm, nurtured for 6 to 7 months, and shipped with an average of 2kg in size. Shipping size varies greatly from region to region, ranging from 900g to 3kg, due to differences in water temperature, stocking size, and shipping by region, and the difference in aquaculture technology also plays a role.

On the other hand, with the recent development of aquaculture technology, the technology of aquaculture the target organisms in the land tank rather than the sea has been established, and by further developing it, the concept of farming various fish and shellfish by floor and tank within a controlled facility such as downtown. Farming methods are also emerging. In general, aquaculture by seawater is largely divided into terrestrial water tanking and sea cage, and terrestrial water tanking is a method of moving and farming target organisms from the sea where it is difficult to predict environmental changes to a terrestrial tank that can artificially control the habitat environment. , Sea-bound style is a method of trapping and raising creatures by installing nets and the like in a large space in the ocean.

However, as the above-mentioned cage farms have been greatly reduced, water pollution caused by the excrement of farmed fish has risen to a serious level that threatens the ecosystem. In addition, the excrement of farmed fish that have leaked to the bottom is deposited at the bottom of the seabed and decays rapidly or It is destroying the aquatic ecosystem by causing eutrophication.

And a tributary-type water tank standing step for purifying 12 hours in each space (D); It consists of a multi-culture tank stocking and breeding stage (e) in which aquaculture trout and abalone or sea cucumbers subjected to the above step (d) are grown in a multi-culture tank.

Hereinafter, specific examples of each step in connection with the eco-friendly composite farming method of the present invention will be described.

(A) Land tank rearing stage

The land tank rearing step (a) of the present invention is to breed the larvae hatched by acquiring the seedlings of one or more fish selected from trout, mountain trout, rainbow trout, red trout, and golden trout, and using 5 termil (‰) or lower land tank It is a step of raising up to 50 g of fish for 7 months by standing.

Trout seedlings are artificially obtained from eggs that are spawned artificially, and are usually obtained from 3-4 year-old broodstock, incubated after artificial insemination in a conventional manner. Trout seedlings may contain sperm and fertilized monooses or triploids of females with a xxx chromosome that has only sexually converted female eggs in addition to those described above.

The fertilized eggs are hatched in a conventional hatching container, and the hatched larvae are transferred to a larval rearing container and a water tank for breeding. The larval rearing tank is raised in a glass fiber tank or a concrete tank, and when approximately 50% of the larvae enter the swimming stage, the initial feed is supplied using an automatic feeder.

When the length of the trout pom is 8-10 cm (250 rice per kg), it is transferred to a land tank containing fresh water, and then raised until the trout body weight grows to 50 g. Trout transferred to the land tank supplies the animal feed additive and feed of the bellflower extract of the present invention.

The trout feed additive of the bellflower extract of the present invention was first washed with water of the bellflower stem including the bellflower stem and leaves, and washed twice with an air bubble washer. Then, it was washed twice with an ultra-high pressure spray nozzle washer and then dehydrated with a dehydrator. 10 kg of purified water was added to 10 kg of the top portion of the prepared bellflower, followed by heating at 100 ° C. for 10 hours under a pressure of 1.5 kg / cm 2 to prepare a bellflower extract.

In addition, the bellflower trout feed of the present invention is spread 10 kg of trout feed (product name: gold trout No. 5, suhyup feed) on a tray and sprays 3 liters of the extracted bellflower extract first. In the above step, the trout feed sprayed with the bellflower extract is first dried at room temperature for 1-2 hours. In the above step, 3 liters of the extracted bellflower extract is secondarily sprayed onto the dried trout feed. In the above step, the trout feed sprayed with the bellflower extract twice is dried at room temperature for 1 ~ 2 hours to feed the bellflower trout feed containing the bellflower extract as an active ingredient twice a day in the morning and evening.

As described above, according to the present invention, the immunity of aquaculture fish is greatly improved by feeding a bellflower extract aquaculture feed additive, the productivity is improved, and the disease is greatly prevented and the mortality rate can be reduced without abuse of antibiotics.

In addition, since the saponin component is detected in the meat and skin of aquaculture fish in which the bellflower extract animal feed additive is ingested, the saponin component is naturally absorbed when a person ingests the cultured fish, thereby improving immunity and improving health.

(B) Transfer stage

In the transfer step (B) of the present invention, the cultured trout subjected to the step (A) is fed to a transfer means equipped with a live fish tank and transferred to a fish tank installed on the shore, but the livestock of the live fish tank in the transfer means is transferred. When the time is 5 hours or more, the salinity is adjusted to 5 to 6 per mill (‰), and for the transfer time of 1 to 3 hours, the salinity is adjusted to 8 per mill (‰).

It is appropriate that the stocked trout of step (B) of the present invention is 50 g or more in body weight. It is appropriate to transport 50 ~ 100g of farmed trout for netting for shorter and higher growth because it is difficult to overcome the net stress of 50g or less and the period of growth of 50 ~ 100g farmed trout in fresh water is relatively long.

The transfer step of the present invention is effective in reducing transport stress and occurrence of mortality in the transfer step by controlling the salinity of the breeding water during the transfer from the inland water surface land farm where the trout is bred to the marine farm.

(C) The initial stage of standing tank

In the initial step of the water tank standing for the fish tank (c), the farmed trout subjected to the step (b) is stocked in the water tank for the initial swimming of the fish farm for the trout, and the water temperature is 15 ~ 17 ℃, and the salinity is 6 to 10 permill (‰). This is the step of fertilizing in the livestock for 10 hours.

The salinity of the breeding water of the transfer means to be transferred to the initial pure water tank is determined according to the travel time, and when the transfer time is 5 hours or more, the salinity is 5 to 6 per mill (‰), and when the transfer time is 1 to 3 hours, the salinity is 8 It is adjusted to permill (‰) and transferred to an initial pure water bath. Therefore, depending on the transfer distance, the salinity of the initial pure water tank can be adjusted to 6 to 10 permill (‰).

Figure 2 shows a plan view of the fish farm for trout of the present invention. In the fish farming system for trout fishing of the present invention, an initial fish tank 10 is installed on the coast to facilitate collection of seawater; One or more sides of the initial water tank for aquaculture are provided with one or more composite aquaculture tanks 30 in the column direction; It is connected to the initial water tank and the composite aquaculture tank is provided with a tributary-type water tank 20 for a circulating type water tank; A water temperature control device 40 is installed to adjust the temperature of the water to be adjusted so that the temperature of the seawater collected from the sea can be supplied to the water tanks at a temperature of 7 to 17 ° C; A circulating filtration device 50 capable of purifying and re-supplying the breeding water drained from the water tank may be installed.

The water temperature control device 40 of the present invention is provided with a casing forming an exterior and an operation control unit for driving the inside of the case to be frozen, and the number of breeders formed of a material such as polyethylene (PE) or polypropylene (PP) inside the case. The supply pipe is extended. Once the intake part of the feed water supply pipe, the feed water collected from the sea is obtained, and the cooled feed water is discharged from the externally installed water outlet through the case, and a pump providing the power to move the water is installed. The water outlet portion of the feed water supply pipe may be connected to a water feed tank, a tributary water feed water tank, and a composite aquaculture water tank to supply cooled water.

As an example, when 5000 tons of seawater collected is supplied to a feedstock for a breeding water having a diameter of 7 cm, and the water supply speed is 23 ° C and the water supply temperature is 6 ~ 7 ° C when the power supply speed is 1 horsepower and the water supply speed is 2 horsepower. Cooling is possible, and the cooling efficiency can be increased more than using a conventional fish pump.

The initial water tank 10 is formed by forming a space where a polygonal tank bottom and a certain height of the outer wall of the tank surround, and an upper portion is opened and a breeding water and aquaculture trout can be stocked. A drainage hole is formed on the bottom of the tank, a water supply device for breeding water and aquaculture water tanks are installed in the water tank opening, and aquaculture trout completed for a certain period of time in the first water tank for one side of the outer wall of the water tank is used as a tributary type water tank. The movable water gate 11 is formed to be opened and closed to allow movement.

In general, as shown in Figure 3, the drain is formed in the center of the bottom of the tank and is formed with an inclination of about 4 ° toward the drain formation position, so that sludge such as aquaculture waste is easily drained by water flow. The drain port is connected to the drain pipe, and the drain pipe is connected to the circulation filter 50 or the outside, and the sludge discharged from the circulation filter can be purified and re-supplied or discharged to the outside.

When explaining the embodiment of the present invention for the initial water tank is as follows. In the initial pure water tank for the present invention, the number of breeders with a salinity of 10 permill (‰) at a water temperature of 15 to 17 ° C. is filled to a depth of 1.2 to 1.8 m, and the farmed trout transferred in step (B) is in stock. The breeding water temperature is an appropriate water temperature at which fish disease occurrence is prevented. In particular, the breeding water temperature is controlled so that the temperature does not exceed 20 ° C so that mass mortality is not achieved.

It is essential to install aquaculture for aquaculture in the initial pure water tank of the present invention. As an embodiment of the aquaculture action aberration of the present invention, a frame and a motor may be installed, and a propeller having a plurality of wing pieces formed on one side or both sides of a shaft shaft rotating in connection with the motor may be configured. The propeller is located on the surface of the breeding tank in the breeding tank, and the rotary blade rotates with the power of the motor to generate bubbles on the water surface and increases the area where the breeding water contacts the air, so that the oxygen in the atmosphere dissolves quickly in the water and is dissolved in the breeding water. While increasing the amount of oxygen, stress is reduced by forming a water stream in a certain direction to the circulating wet trout. An opening and closing device is formed at the bottom of the aberration to open and close when the trout moves into a tributary tank having a different salt concentration.

(D) Feeding stage for tributary type pure water tank

Feeding-type tank for standing feeder (D) of the present invention opens the transfer gate of the initial tank for step-keeping in step (C) to transfer the farmed trout to the branch-type catching tank. The first to fifth incisor spaces have a depth of 1.2 to 1.8 m.

The initial water tank and the tributary-type water tank are connected via a mobile hydrogate, and the cultured trout adapted to salt water for 10 hours with a salinity of 10 permil (‰) in the initial water tank is a mobile water gate and a first water gate (22a). It can be moved to the first formed labial space and can be labed for 12 hours. A water hole for aquaculture farms is installed at the top of the first water gate, and a water hole can be formed in a certain direction in the first space. The breeding water is maintained at a salinity of 10 permil (‰) while the farming of the farmed fish is transferred to the salinity of the initial tank and the first tank.

The space formed by the installation of the first and second water gates (22b) is fed to the second pure water space for 12 hours by supplying breeding water with a salinity of 15 permil (‰), and the second water gate and the third water gate (22c) The space between the installed and formed is supplied to the third pure labyrinth with a salinity of 20 permil (‰) for 12 hours. The space between the 3rd and 4th water gates (22d) is installed, and the 4th pure water is supplied to the breeding water of salinity 25 per mill (‰), and the 4th and 5th water gates (22e) are installed and formed. The space is supplied to the fifth pure water space with a salinity of 33 permil (‰) and purified for 12 hours at each salinity condition.

4 is a plan view of a feeder-type pure water tank of the present invention. Feeder-type water tank 20 of the present invention surrounds a polygonal tank bottom with a water tank outer wall of a certain height, and a space for breeding and farming trout is formed, and either side of the water tank outer wall is combined with an initial water tank. Aquaculture tanks are connected to each other through a water gate, and form a predetermined interval in parallel to the direction in which the water tank and the compound water tank are installed, and at least one partition 21 is installed in the upright space of the tributary-type water tank. The first to fifth sluice gates are installed in the interspace formed by the partition walls, so that the upright space of the tributary type water tank can form a water channel having a zigzag shape in a plane.

The partition walls are provided with first to fifth sluice gates, so that the first to fifth stern spaces can be formed in the tributary type tank, and aquaculture aberrations are installed at each sluice gate, so that the first to fifth sluice spaces have a fixed direction. As a result, water flow may be continuously formed. A water gate opening and closing device is formed at the bottom of the aberration, so that a pure trout is opened and closed when moving, so that the pure water space based on each water gate has different salinity values.

The initial water tank and the tributary type water tank are connected via a mobile water gate, so that the cultured trout that has undergone step (c) can be kept for 12 hours in the first water tank space formed by installing the mobile water gate and the first water gate 22a. You can. A water hole for aquaculture farms is installed at the top of the first water gate, and a water hole can be formed in a certain direction in the first space. In the present invention, the water depth of the tributary-type pure water tank was supplied with the water depth of 1.2 m, the same as the water depth of the initial pure water tank.

(E) Stocking and breeding stage of the complex aquaculture tank

In the step of erecting the composite aquaculture tank (E) of the present invention, the trout that has undergone the step (D) is opened to the composite aquaculture tank 31 and moved to the composite aquaculture tank 30, and then reared with sea cucumber and abalone. It is a step.

The composite aquaculture tank 30 of the present invention is formed by surrounding a polygonal tank bottom with an outer wall of the tank, and a composite aquaculture water gate 31 is formed on one side of the water tank outer wall, thereby being connected to the feeder-type pure water tank. Aquaculture trout can be moved.

A drainage hole is formed at the bottom of the tank of the composite aquaculture tank, and the drained breeding water is moved to a circulating filtration device and then purified and re-supplied to the breeding tank or discharged to the outside. As an embodiment of the present invention, the salinity of the breeding water in the composite aquaculture tank is 33 permil (‰) of seawater used as the breeding water, and the water depth is supplied from 1.2 to 3.6m.

The supplied breeding water temperature is adjusted to 10 to 18 ° C and supplied. In the water temperature control device according to the present invention, since the collected seawater flows through the pipe to the inside of the device, cooling is performed, and energy saving and cooling time can be shortened. In addition, a flow rate control device for controlling the flow rate of water may be further provided for deposition of feces or surplus feed generated according to aquaculture.

When the water depth formed by the number of breeders in the composite aquaculture tank is formed to be 1.2 m, it simply serves to keep the seawater-pumped trout in the composite aquaculture tank, and supplying the water depth of 3.6 m or more to perform a complex culture of heterogeneous organisms. It is for sake. That is, trout usually inhabit at a depth of 1 to 2 m, and benthic organisms, such as sea cucumber, inhabit at a depth of 1 m or more, allowing complex farming. By breeding aquatic organisms capable of breeding heterogeneous organisms, such as sea cucumber, sea cucumber can be used to reduce the feed value and to achieve high growth.

The feed supplied to the composite aquaculture tank is sprayed with 2 liters of 3 liters of bellflower extract extracted from the dried trout feed in step a), and the trout feed sprayed with the bellflower extract in the step is dried for 2 to 2 hours at room temperature. Then, the trout feed containing the bellflower extract as an active ingredient is fed to the morning and evening twice a day.

When feeding the aquaculture feed with the bellflower extract as an animal feed additive to the composite aquaculture tank, the farmed trout feeds most of the amount and the remaining feed sinks on the bottom of the composite aquaculture tank, and the feed crumb deposited on the bottom Abalone or sea cucumber is fed.

Accordingly, according to the present invention, the immunity of aquaculture fish is greatly improved by feeding a bellflower extract aquaculture feed additive, the productivity is improved, and the disease is greatly prevented without the abuse of antibiotics, and the mortality rate can be reduced.

In addition, since the saponin component is detected in the meat and skin of aquaculture fish in which the bellflower extract animal feed additive is ingested, the saponin component is naturally absorbed when a person ingests the cultured fish, thereby improving immunity and improving health.

Table 1 shows the results of examining the saponin content from the truncated trout and the untrapped trout of the trout cultured in the present invention. The experimental method is to divide the peeled trout and the unpeeled trout by 160g, and pulverize finely using a blender. Put the sample into the Erlenmeyer flask, dissolve in 1 L of water, install the Liebig cooling tube, and heat it to 100 ° C using an electric oven to obtain each extract. Each extract is first filtered using an 80 mesh sieve, and second filtered using a vacuum filter (using filter paper No. 2 (5 μm)). The saponin content was examined from the filtered extract.

sample Saponin content (mg / g) Trout 0.44 Unshelled trout 1.60

As a result of the test, the saponin content was detected from the untrapped trout and the untrapped trout. In addition, attached to the bottom of the composite aquaculture tank can be attached to aquaculture organisms so that benthic organisms can grow. The attachment biological aquaculture device is a wave plate installed in a land culture tank of sea cucumber or abalone, a pair of wave plate holders or a bone structure in which a plurality of seating rods on which both ends of the wave plate are mounted horizontally are arranged in the up and down direction. It can be made of a shelter.

The inner wall of the composite aquaculture tank may be formed with a protrusion at a certain height, and the protrusion may be used to mount a horizontal mesh. It is preferable to form protrusions of a certain height at a location of 1.2 to 1.6m when the composite aquaculture tank is 3.6m deep. The horizontal mesh consists of a rectangular frame that can divide the composite tank horizontally, and distinguishes the upper and lower parts based on the depth of water. By separating the upper and lower parts by the horizontal mesh, it is possible to prevent seaweed, such as kelp, which is the food of abalone, from sinking to the bottom and decaying, and to physically separate the abalone or sea cucumber habitat.

As another embodiment of the present invention, it is possible to carry out a composite farming by moving to a seaside rim after standing in a composite farming tank. In the case of farming trout with an initial weight of 50 g by standing in the composite aquaculture tank of the present invention, it is appropriate that the step (E) is reared with a body weight of 100 g for about 30 days, and then moved to a seaside cage.

In the eco-friendly composite farming method of the present invention, by breeding trout and sea cucumber, which have almost no net stress, fish excretion and surplus feed, organic matter, and inorganic matter are provided as nutrients to sea cucumber growth during fish farming. In addition to being prevented, aquaculture organisms can be stored at a high density per area. In addition, the trout stored in accordance with the present invention has almost no mortality due to pure stress, and thus, it is possible to mass-purify overcoming the existing method that could not carry more than 1000 kg of pure fish.
