Description

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

The present invention relates to a complex culture method with benthic creatures in a trout fish farm, and to an eco-friendly complex farming method that can be a complex culture of attachment organisms, such as trout and abalone or sea cucumber that overcomes the stress of the canon.

Trout live in cold, clean primary water. After hatching, they inhabit the river, then descend to the sea, live as mothers, return to the river, lay eggs, and end their lives. Originally, salmon have a physiological adaptation function to seawater, so they can be grown in the sea after a certain period of time. Due to these characteristics, the trout farming using seawater is naturally possible, but the seawater level must be established to carry out the trout farming.

The seawater marinating process is a step in which fish larvae are moved into a breeding tank and the fish's osmotic pressure regulating ability continuously increases 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 saline cells, which absorb the salts through 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 land 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.

On the other hand, the development of aquaculture technology has recently established a technique for farming target organisms in land tanks, not the sea, and further developing them to produce various fish and shellfish by layer and tank in controlled facilities such as urban areas. Aquaculture methods are also emerging. In general, aquaculture is divided into terrestrial tanks and marine cages, and terrestrial tanks are a method of transferring a target organism from a sea where it is difficult to predict environmental changes to an onshore tank that can artificially control the habitat environment. Sea cages are a way of raising and trapping creatures by placing nets in large ocean spaces.

However, as the cage farming has become large, the water pollution caused by the excreta of farmed fish has risen to a serious level that threatens the ecosystem, and the excreta of farmed fish spilled out to the sea bottom is rapidly decaying or It causes eutrophication and is destroying aquatic ecosystems. In this regard, Korean Patent No. 10-1786188 discloses an energy-saving eco-friendly farm and its installation method, and Korean Patent No. 10-1779835 discloses an eco-friendly circulation farming apparatus, but the preceding document is a trout of the present invention.

And a tributary type water treatment tank stocking step (d) which patrols for 12 hours in each treatment space; Comprised of the (d) step seawater tuna cultured trout and abalone or sea cucumber stocked in a complex aquaculture tank breeding and breeding stage (e) consists of.

Hereinafter, the concrete examples of each step in relation to the eco-friendly complex culture method of the present invention will be described.

(A) Land tank breeding stage

The land tank breeding step (a) of the present invention is to breed the larvae hatched by obtaining the seedlings of one or more selected fish from trout, mountain trout, rainbow trout, red trout, golden trout, and less than 5 per mill (‰) land tank Stock up to 50g of fish for 7 months.

Trout seedlings obtain eggs more artificially than naturally laid eggs and are usually obtained from 3-4 year-old larvae and incubated after artificial insemination by conventional methods. Trout seedlings may include spermatozoa and fertilized monox or triploids of females with xxx chromosomes, in addition to the species described above, that only females have sex-transferred normal female eggs.

The fertilized eggs are hatched in a conventional hatching vessel, and the hatched larvae are transferred to larval rearing containers and tanks for breeding. Larval rearing tanks are reared in glass fiber tanks or concrete tanks, and when the 50% of the larvae enter the swimming stage, they feed the initial feed using an automatic feeder.

When the trout is 8 to 10 cm in length (250 micrograms per kilogram), it is transferred to a land tank containing fresh water, and then raised until the trout grows to 50 g. The trout transferred to the land tank supplies the bellflower extract animal feed additives and feed of the present invention.

The bellflower extract trout feed additive of the present invention was first washed with water the bellflower ground portion including the bellflower stem and leaves, and washed twice with an air bubble washer. Then, after washing twice with an ultra-high pressure jet nozzle washing machine, it was dehydrated with a dehydrator. After adding 10 kg of purified water to 10 kg of the prepared bellflower grounds, the bellflower extract was prepared by heating at 100 ° C. for 10 hours under a pressure of 1.5 kg / cm 2.

In addition, the bellflower trout feed of the present invention spread 10kg of trout feed (product name: gold trout No. 5, suhyup feed) widely on a tray and first spray the 3 liters of the extracted bellflower extract. The trout feed sprayed with the bellflower extract first in the above step is first dried at room temperature for 1-2 hours. In the step, the dried trout feed again sprayed 2 liters of the extracted bellflower extract. In the above step, the trout feed sprayed with the bellflower extract secondarily dried at room temperature for 1 to 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 the cultured fish is greatly improved by feeding the bellflower extract cultured feed additive, and the productivity is improved, and the disease is greatly prevented without the abuse of antibiotics, and mortality can be reduced.

In addition, saponin components are detected in the meat and shells of farmed fish ingested with bellflower extract animal feed additives, and when humans consume the fish, the saponin component is naturally absorbed, thereby improving health and improving health.

(B) Transfer stage

In the transfer step (b) of the present invention, the aquaculture trout passed through the step (a) is stocked on a transfer means equipped with a live fish tank, and then transferred to a pure water culture tank installed on the shore, and the breeding water of the live fish tank in the transfer means is transferred. If the time is more than 5 hours, the salinity is adjusted to 5 to 6 mill mill (‰), and if the transfer time of 1 to 3 hours, the salinity is adjusted to 8 mill mill (‰).

The stock farmed trout of step (b) of the present invention is preferably at least 50g. Since less than 50g of farmed trout is difficult to overcome the net stress, and 50-100g of farmed trout grows in freshwater relatively long, it is appropriate to transfer 50-100g of farmed trout to the net for shorter periods and higher growth.

The transfer step of the present invention has the effect of reducing the occurrence of mortality in the transfer stress and the pure teeth step by adjusting the brine salinity in the process of transporting from the inland land farms where the trout breeding is carried out to the offshore farms before the marinating process.

(C) initial pure water tank stocking stage
