Description

Live anchovies and how to breed {ACCLIMATION AND METHOD FOR REARING OF LIVING ANCHOVY}

The present invention relates to a method to allow live breeding of anchovies to be reared, and more particularly, to lure anchovy flocks to a cage, collect and feed them, so that they can be reared and fished in tanks. The present invention relates to a live anchovy fish roe and breeding method.

The cross section of the anchovy body is close to oval and flat to the side. Mouth large and slanted at an angle. The upper jaw protrudes toward the front of the head, and both jaws have fine teeth. There is no scute along the midline of the abdomen, forming a sharp ridge, appearing behind the lateral line of the horse mackerel and above the abdominal line of the word or mucus. Dorsal and anal fin without spines. The dorsal fin is located at the center of the body and the pectoral fin is biased to the belly. The back of the body is dark blue, and the center and belly are silver white.

Anchovy is also a turbulent fish. They usually live in continental shelf waters with a depth of 0 ~ 200m. They live in groups near the surface where they live off the coast in spring and summer and then move further north.

When it is a young fish, it floats on floating algae. Prey are copepods, small crustaceans, larvae of mollusks and fish eggs. Spawning occurs twice in spring and autumn, and spawns in the night at a depth of 20-30 m. Life is about a year and a half.

Anchovies die immediately after being lifted from the water, so there are difficulties from collecting live anchovies.

In general, there are methods for treating pure fish such as mandarin fish, trout, salmon, sturgeon and the like.

The mandarin fish farming method is to feed groundwater to feed frozen fish, and the trout, salmon, sturgeon, and mountain trout farming method moves the fish into the breeding tank, and continuously increases the salinity of water in the breeding tank. It is composed of the step of adapting to survive in salinity corresponding to the seawater and the cultured fish in the seawater after the adaptation step. Since the step is suitable for fish having both osmotic pressure regulating ability of freshwater fish and seawater fish, it is impossible to breed them in the same farming method as the above fish.

In addition, until now, there is no way to cure anchovies and raise them in aquariums, so there is no way to breed and display live anchovies in aquariums far from the sea. .

An object of the present invention is to invent the conventional drawbacks as described above, after attracting and collecting live anchovy herds so that the anchovies in the narrow space so that they do not die in a narrow space and can be adapted to breed in the tank A live anchovy is provided to provide a method of quenching and breeding.

In order to achieve the above object, the present invention puts a net cage under the surface of the water to attract the anchovy herds, and to collect and feed the cage to the net net, the pure anchovy containing water and antibiotics It is then sealed and moved in a plastic box infused with oxygen, and provides a method of raising anchovies in a water tank equipped with a pressure filter, a sterilization skimmer, a bioball, a warmer, and a cooler.

According to the live anchovies and breeding method of the present invention, unlike the prior art, live anchovies can be displayed in a tank and live anchovies, children, students, etc., you can directly see the live anchovy flocks in close proximity without having to go to the beach It can be used as a very useful effect.

1 is a perspective view of the cage open to collect anchovies.
Figure 2 is a side view of Figure 1;
Figure 3 is a perspective view of the cage closed after collecting anchovies.
4 is a side view of FIG. 2;

The present invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a cage net opened for collection, FIG. 2 is a side view of FIG. 1, FIG. 3 is a perspective view of a cage closed after collecting anchovies, and FIG. 4 is a side view of FIG. Under the water surface, the cages are put together to collect the anchovy flocks and to be raised in a tank.

A part of the cage net 100 is confined and tied to the jungdae 110, hanging the weight 120 to the edge of the cage 100 is put in the depth of about 2m ~ 5m below the water surface. If you turn on the light of more than 250W at night to see the light anchovy flock gathers at this time, pull up the cage 130 under the water pull up the rope 130, trap the cage and tie it to the bandage and trap the anchovies in cage.

If you put the small shrimp (krill) in the frozen state in the caged net 100 in the frozen anchovy so that the shrimp fall a little while moving down as if the shrimp live, so that anchovies can eat. By attaching the food in the same way as described above about 1 month to 2 months.

Feeding anchovies in a narrow space for 1-2 months in this way is intended to allow the anchovies to survive in a narrow space. When anchovies are moved to an aquarium and exhibited, and the anchovy period is longer than 2 months, it is sufficient to adapt the anchovy to a narrow space, but it takes unnecessary time. It is advisable to go on

Water and antibiotics are added to the whole vinyl, and the pure anchovy is added, filled with oxygen and tied with rubber bands.

The antibiotic is injected in order to prevent the death of the anchovy during the movement of the anchovy during the movement so that the wound does not spread and the wound is healed.

Adding oxygen to the barrel vinyl supplies oxygen necessary for the anchovy to breathe in the process of moving the vinyl containing the anchovies, and prevents the anchovy from dying due to lack of oxygen. Seal both sides to prevent damage.

Put anchovies and oxygen-filled plastic container in a box filled with ice water, cover it with wet newspaper to maintain humidity, and close the lid to seal it.

Since anchovy is a turbulent fish, put ice water in the box to lower the water temperature so that the anchovy is in a masked state so that anchovy does not die due to stress during transportation.

It is suitable to put about 25 to 35 anchovies in 7.5 ~ 12.5L of water and 15 ~ 25PPM of antibiotics in the whole vinyl. Ortishi fish farms are usually prescribed about 30PPM ~ 50PPM for the prevention and treatment of bacterial diseases. ~ 25PPM is suitable.

In addition, carp and crucian carp are very gentle in nature and consume less oxygen, and may be transported in large quantities. Eel can be transported for a long time even by cooling packaging without water.

However, anchovies are an oily fish, and the oxygen consumption is very high and the nature of the anchovy is high.

The transported anchovies are not immediately released from the vinyl, but are floated in water as it is until the water temperature in the vinyl and the water temperature in the tank are the same, and then the anchovies are released into the tank.

This is to adjust the temperature after leaving it in the tank for a long time in order to be able to adapt to the temperature of the tank in order to prevent the anchovy is not adapted to the sudden change of temperature and death.

The tank is suitable for about 400 to 600 in an elliptical tank or round tank of about 8 to 12 tons because anchovy is an oil. When the amount of anchovies is small compared to the tank, it is difficult to provide sights to visitors because anchovies are not formed.

The oval or circular tank was created because the anchovy's appeasement caused the anchovy to move continuously and it was convenient for many people to observe from different directions.

The water tank is equipped with a pressure filter, a sterilizing skimmer, a bioball, a warmer, and a cooler.

The pressure filter is to prevent the tank from being contaminated by contaminants generated by food or anchovies excreta in the tank to always clean the water in the tank to prevent the anchovy from being killed.

In addition, the use of a pressure filter has a uniform sand in the filter, the biological filtration is performed as the circulating water evenly passed through the sand.

In addition, the pressure filter is backwashed when a lot of pollutants are adsorbed, it is very convenient to instant backwash using a pump. Backwashing refers to washing with continuous filtration of liquids.

The sterilizing skimmer is a device that pushes and removes the residue in the water as a bubble to remove foreign substances in the water as a device to help maintain the water quality without frequent water change.

The bioball has a function of pulverizing foreign substances by creating a strong water flow, and performs biological filtration over time.

The warmer and cooler is a device to maintain the water temperature in order to prevent the anchovy from death due to the temperature decrease in winter or the temperature rises in summer.

Anchovy is turbulent fish, the optimum breeding water temperature is 18 ~ 20 ℃ suitable for the tank, the specific gravity is preferably about 35%.

Anchovy raw feed is suitable for krill, and artificial feed uses early feed for fish seedling production.

Anchovies feed on krill in the sea, but if you give krill in the tank, the water in the tank becomes turbid so that it is difficult to see, so the initial feed, which is the most nutritious and commercially suitable for anchovy, is suitable. .

Therefore, according to the present invention, unlike the prior art can be displayed live breeding anchovies in the tank, children, students, etc. can be seen directly near the live anchovy herd without having to go to the beach and can be used for display There is this.
