Description

Eco-friendly tributary trout fish farm {APPARATUS FOR ACCOMMODATION TO SEA WATER FROM FRESH-WATER IN TROUT FISH}

The present invention relates to a tributary fish farm that is seawater-treatable for farming trout seeded in freshwater in seawater. It is related to tributary trout farming farms that are made of water tanks, which can reduce the stress generated when transferring from freshwater farms to net farm farming.

The trout (松 魚, cherry salmon / masou salmon, Oncorhynchus masou), which is said to be similar to the color of pine joints, is a cold-water fish belonging to the salmon family Salmon family. It is thick, round, slightly flattened, and its snout is blunt.

Body color is dark blue in back of abdomen, silver white in belly, and small dark brown spot on side. The fish is dark greenish yellow with a light gray color from the lateral line to the dorsum. Eye circumference is black with black spots scattered on the eyeballs. The pectoral fin, badge fin, and hind fin of the young fish are light orange, and the soft color of the fin is black gray.

Trout is known as rainbow trout, red trout, and wild trout. Indigenous trout, also known as sea trout (sea trout, and trout), are not cultivated and live near the sea and are often caught on the political network of the east coast. Domestic trout farming began in Pyeongchang, Gangwon-do in 1965, importing 10,000 rainbow trout eggs from Henrycline Schmit, California, USA. In 1982, as the first feed compound for trout farming was developed, the production volume exceeded 100 tons. At the end of 1980, dam cage farming became popular at Chungju Dam, Daecheong Dam, and Soyang River Dam.

However, trout farming has been stagnant due to the economic downturn caused by the IMF, tightening water quality regulations, restrictions on farming areas, productivity declines, and avoidance of mass mortality and seedling production by fish disease, especially in the 1970s. In 1999, the cage farming license, which was prevalent in large lakes, was banned.

Trout farming, which was in recession due to such bad news, is trying to leap again by attempting seawater trout farming, which was first attempted in 2008. In addition to rainbow trout, it is increasing its species such as shima salmon and golden trout.

Trouts live in cold, clean, first-class water, live in rivers after hatching, live down to the sea, return to the rivers, lay eggs, and end their lives. Originally, salmon have a physiological adaptation function to seawater, so it is possible to cultivate it in the sea after a certain period of time, so the trout farming using seawater is naturally possible. The seawater marinating process is a process of moving fish from a fish tank into a breeding tank and using the osmotic pressure control ability of the fish to continuously increase the salinity of water in the breeding tank so that it can survive in the salinity corresponding to the seawater.

In the case of freshwater fish, body fluids are more salty than environmental waters, so water continues to penetrate through the gills, digestive organs, epidermis, and so on. It will keep your body hydrated. At this time, monovalent ions such as Na + discharged with urine are absorbed from the tissue epithelium, such as kidney and bladder, and salts contained in the food are absorbed from the intestinal epithelial cells. In addition, the fresh stools of gills have fresh water-type salt cells, which absorb the salts by the action of vacuole proton ATPase enzymes to maintain the salinity of body fluids. In the case of sea fish, since the body fluid is lower in salinity than environmental water, large amounts of sea water are introduced into the body to prevent physiological dehydration and absorb water from the intestines.

Trouts belonging to the salmon family biologically hatch in freshwater and grow into larvae, then undergo salinity in the brackish waters during the Smolt season. Therefore, freshwater should be supplied from land tanks, brackish water from nets installed in land or sea space, and seawater from sea cages.

Since moving trout used to freshwater to the sea is quite burdensome for fish, it is appropriate to breed the fish in a state that is healthy and able to withstand changes in the environment, and then move it to seawater. When it is raised in (land) and about one year passes, weight is about 200-350g in general.

Therefore, in the conventional inland farms, the intermediate reared fish of about 200g is purchased, and after a certain period of time, seawater cages are stocked in marine cages or onshore tank farms, and they are bred for 6-7 months to be shipped as average 2kg fish. Shipment sizes vary from region to region, ranging from 900g to 3kg, due to differences in regional water temperature, stocking size, shipping time, and aquaculture technology.

However, the mortality rate is high during the process of pure water from the fresh water. Therefore, as a prior art to prevent this, Korean Patent Registration No. 10-0979406 (name of the invention "treatment and farming method of trout and salmon" and Korean Patent Publication No. 10-2015-0055214 ("Rain using water) Trout farming method ”can be mentioned, but the above-mentioned literature focuses only on the process of pure tuna, and it is not mentioned or developed about the farm which is set up to reduce the net stress in accordance with the characteristics of trout. .

In Korean Patent Laid-Open Publication No. 10-2015-0055214, a tank is not used to farm trout without any weight, and after the rainbow trout is grown to a size suitable for salinity in freshwater farms, the salinity is 12 ‰ ~ The river estuary, which is 25 ‰ (per mill), is transferred to a cage in a waterway or channel, where it is cured and then moved to the sea (sea) with rainbow trout for two months to produce 93% or more survival. Disclosed is a rainbow trout farming method used. Korean Patent No. 10-1252620 has a space portion for containing fresh water or sea water is formed, the hull formed to be moved in the water or water; A fresh water injection unit connected to the space unit and configured to supply fresh water; A water gate provided at one side of the hull and formed to allow seawater to enter and exit the space portion; A variable buoyancy body disposed on one side of the hull and formed to provide buoyancy to the hull; And it relates to a mobile maritime device for a salmon or trout farming comprising a buoyancy control unit is formed to adjust the buoyancy of the variable buoyancy body. Korean Patent No. 10-1752177 includes the steps of preparing and screening female fry of trout and fish farmed in fresh water; And quenching the fry in seawater. The present invention relates to a method for reducing mortality in the process of quenching trout. According to the present invention, it is possible to provide a low mortality farming method in the staged seawater level of trout and fish such as rainbow trout, which can increase the efficiency of aquaculture, and contribute to the reduction of operating costs of aquaculture Disclosed are methods for reducing mortality in the process of sea trout in trout and fish.

The present invention, in order to solve the problems caused by the stress caused during the transfer from the land farm to the seawater fish farm in order to patrol sea trout farmed in fresh water, seawater water level and breeding was difficult, the recirculation connected to the initial pure water tank It is intended to provide a channeled tributary pure water tank and a combined culture tank for storing and storing pure trout.

The tributary type pure water tank 20 of the present invention is surrounded by a tank outer wall of a certain height and a space in which breeding water and farmed trout are stocked, and a side portion of the tank outer wall is complex with an initial pure water tank. Aquaculture tanks are connected to each other by a water gate, and form a predetermined gap in parallel with the direction in which the pure water tank and the complex culture tank are installed, and one or more partition walls 21 are installed in a standing space of the tributary pure water tank. The first to fifth sluices are installed in the interspace formed by the partition wall, so that the standing space of the tributary water treatment tank can form a zigzag flow channel having a zigzag shape in the plane.

The partition walls forming the flow channel may be provided with first to fifth water gates, and the tributary water treatment tank may have first to fifth pure water spaces. In each spawning space, the number of salinity of each salinity is filled, and the trout stays for 12 hours in each of the salinity spaces, and moves in accordance with salinity. Aquaculture farm aberration is installed in the water gate, the water flow can be continuously formed in a predetermined direction in the first to fifth punch space.

The initial pure water tank and the tributary pure water tank are separated and connected through the mobile floodgate. In the initial pure water tank, brine adapted to brine for 10 hours with salinity of 6-10 per mill (‰). The trout may be moved to the first pure space formed by the mobile gate of the initial pure water tank and the first gate 22a of the tributary pure water tank, and may be sunk for 12 hours. At the same time, the first water gate is formed with a moving hole through which the farmed trout can move, and at the same time, the aquaculture aberration is installed at an upper portion thereof so that water flow can be formed in a predetermined direction in the first space. While the salinity of the initial pure water bath and the cultured trout in the first pulp space are kept, the breeding water is kept at the same salinity of 10 milliliters as the initial pure water bath.

However, the brine water salinity of the transfer means to be transferred to the initial pure water tank is determined according to the movement time, and when the transfer time is 5 hours or more, the salinity is 5-6 millimeters (‰), and the salinity is 1 to 3 hours. It is controlled by 8 mill mill and is transferred to the initial pure water tank. Therefore, the salinity of the initial pure water tank according to the transport distance can be adjusted to 6 to 10 mill mill (‰).
