Description

TECHNICAL FIELD The present invention relates to an artificial harvesting apparatus for artificial harvesting,

The present invention relates to the production of artificial seedling seeds, and more particularly, to an artificial seedling artificial seedling production method which comprises a new artificial seedling attachment ratio and a new artificial seedling growth rate Artificial shedding device.

Unlike the west coast and the south coast, the east coast is a clean sea with a steep coastline and steep slopes of the continental shelf, and it is a clean sea without pollution. The turbulent flows between North Korea and Korea are mixed with each other and turbulent fish species such as pollack and squid are mixed. It has abundant fishery resources.

At depths of 200m, deep seawater below 2 ℃ is formed. It has good environmental conditions for deep sea creatures such as cod, hair crab, crab, and red sea crab. However, as the surface water temperature of the East Sea has increased by about 0.6 ℃ for the past 30 years and the productivity of the sea fishery has been lowered due to the increase in the number of shrubs, It is necessary to develop technology for improving productivity.

There are over 360 species of scallops in the world, and it is a world-famous shellfish, as Botticelli, who depicts Venus, the goddess of love and beauty in Greek mythology, paints the birth of Venus on the scallop shell. There is one scallop current commercial species which are the subject of a form or fishing is about 30 or more in Chlamys, Mimachlamys, Aequipecten, Palliolum, Decatopecten, Pecten herd, species belonging to the double Chlamys and Pecten crowd high commercial availability. In Korea, there are Jumunjin scallops, participated Libby, silk scallop, scallops, etc. This year alone format that participate in the distribution of the country east Libby (Patinopecten yessoensis) is Pecten It belongs to the herd, and is a strong species of coastal area. It extends from the coast of the middle east and north coast of the east coast to Okhotsk, Sakhalin and Kuril Islands.

Participation Libia is taxonomic and belongs to Mollusca, Bivalvia, Filibranchia, Plectinidae, and Patinopecten.

Participation Libby is a different species of male and female varieties, mainly in the East Coast region, which lives in fine sandy areas with a depth of 20 ~ 50m. Participation Libby is filtering the floating creatures living in the sea and eating it. When the taste is the best three years, it will grow to 15cm in length and weigh more than 200g.

Participation festivals were started in Gyeongbuk Youngil Bay in the 1980s. However, since the first production of 6.2 tons in 1991, the production area was 605 tons in 1994 and 1,200 tons in 1996. Since the massive death of scallop in 1997, Shoji has shown a decline every year from 536 tons in 1998 to 555 tons in 1999. The scallop aquaculture industry was in crisis due to the difficulty of securing seedlings due to the loss of natural seedlings and the death of natural spoilage as well as the massive deaths in 2001, and the scallop spoilage was maintained in China.

Since 2003, the East Sea Fisheries Research Institute has analyzed the participatory livestock industry as a whole and evaluated that it has a production potential of 30,000 tons in the existing system and 100,000 tons in the case of base construction. As a result of the enlargement policy, we have established a strategy for the development of aquaculture as a 100% import substitution and export strategy product. In order to realize the production potential of participating livestock, the cause of our cause was requested first, and we developed a real - time fishery environment information observation system and confirmed that our cause was "sudden change of water temperature during the day" from 2003 to 2005. In 2005, we developed a technique to mass-produce water-resistant artificial seeds and succeeded in field test at Gangwon-do test site. In order to put the developed technology into practical use, we signed MOU with Gangwon-do Fisheries Resources Institute equipped with artificial seedling production facility. , And succeeded in producing 50 million artificial seedlings (at the time, the total amount required to support the entire participating livestock industry in Korea was 40 million).

Participation of the East Sea Fisheries Research Institute The success of the artificial seedling production of the livestock industry due to the mass loss of scallop farming business to bring back to the scallop industry has brought the opportunity. Participation Libia Water Resistance As artificial seed production technology has been developed originally, the institute has been continuing education / training to transfer technology to the private sector. Finally, from 2011, And 50 million artificial seedlings with fishermen. From 2012, fishermen will continue to train fishermen to produce artificial seedlings directly. Thus, the Donghae Fisheries Research Institute is trying to solve the difficulties of the scallop farmers by developing mature techniques of high quality moth, establishing artificial seed mass production technology, and developing the technique of cultivation such as intermediate fertilization to promote the scallop aquaculture industry.

On the other hand, the participation Liby is a representative high quality shellfish distributed in Korea (including North Korea), Japan, and Russia coast in the East Sea, and large markets are formed internationally in China and Japan, and the market scale of Korea and Russia is gradually increasing. to be.

China, a representative importing country, has succeeded as a result of steady efforts for aquaculture in its coast by importing the livestock of the East Coast since 1982 as the market size has been gradually increasing. However, in the late 2000s, Production is in a state of worrying about imports again. China's participation in livestock form was succeeded in 1982 when the seedlings were transplanted from Japan and succeeded in producing artificial seedlings and then raising rafts in Balhae Bay. Since then, there has been a production of churning and spermatozoa And the whole seed production is done by artificial seedling.

However, in recent years, it is expected that mass production of fish in aquaculture mode will occur due to environmental deterioration of adult fishery farming farms, and production of pelagic animals such as oysters will be severely deteriorated, resulting in a significant decrease in production. Currently, the number of Chinese products imported into Korea is about 3,000 tons per year. Although it may temporarily increase due to Japan's earthquake and radioactive spills, it seems that the Chinese scallop industry is gradually losing its vitality to such an extent that it is never threatening from a long-term point of view.

The participation in the Chinese liby is lower than the quality of the mountain in Gangwon-do. The reason is that first, the libby is not supplied as a main dish, but is sold as an auxiliary dish. Therefore, in order to meet the price, It is being imported.

Second, because the transportation time and the customs procedure of China imported in Korea takes 7 ~ 10 days, there is a problem that the freshness is reduced even if it is stored in the water tank in the state of a flap. In the long run, China can not rule out the possibility of importing from Japan or North Korea, or even from Korea. Unlike China, which is the most aquaculture country in Japan, Japan produces stable 300,000 tons per year and is exporting to China and Korea as well as its own consumption. However, in 2011, As a result of the material outflow, the import of livelihood into the domestic market will be difficult for the time being. Russia's output is about 10,000 tons per year, and most of the participation ribbons in Russia can be regarded as natural, and production is gradually decreasing.

Participation in Russia Liby is reported to have some cultures but it is still only a few hundred tons and scallops are the preferred shellfish in Europe, so Russia has no significant advantages as aquaculture production area. Since it is small and tough, the participation of livestock in Russia will not have a big impact on our country.

The production of livestock in North Korea has not been officially reported, but it is estimated that at least 4 ~ 5,000 tons will be cultivated when the distribution status is judged. North Korea is estimated to have been imported into Korea since 2003, and North Korea's participation style is believed to be produced by Chinese capital and technology. What we are noticing is that North Korea can cultivate the entire East Coast, so the potential for cultivation of North Korea is expected to be up to 50,000 tons on the premise that technology and capital support it.

Currently, the production of livestock is about 300 ~ 400 thousand tons in Japan, 50 ~ 200 thousand tons in China, 10 thousand tons in Russia, 4000 tons in North Korea and about 500 tons in Korea. International prices are in the range of 3 to 5 dollars / The total annual market is in the range of $ 15 billion to $ 2.5 billion, and it is expected that an enormous international market will be formed when the production volume can be increased in the future.

The life of the participant Libby begins with the spermatozoa released from the egg, and the egg is separated from the egg shell by about 80 ㎛ and the egg number is about 3 years (10 ~ 12㎝) It is about 180 million pieces in 6 years (around 15 cm each). Only in males, sperm production begins in the second year.

In Gangwon province, the gonads began to develop from the beginning of March when the lowest temperature of the year (late February) gradually increased. From mid-April to mid-May around 8.0 ~ 11.5 ℃ (scattering critical temperature 8 ℃) Spawning takes place ~ 3 times. Nitzschia , a feeding phytoplankton feeding larvae closterium , Pavlova lutheri , Isochrysis galbana, Chaetoceros calcitrans And Tetraselmis suecica are mixed and supplied.

Participation of Libbye spawning starter is considered to be necessary to manage the motherland by investigating the low temperature of winter water temperature in the management of seedling for the artificial seed production in Korea since the matured seedlings are good at the temperature below 7 ℃.

At a temperature of 16 ℃, embryos begin spiral cleavage, pass through the gastrula stage, and after about 1-2 days they become trochophore larvae, float and swim, and begin feeding.

After 2 to 3 days of fertilization, a hinged D-shaped larva, which is an early veliger with a flagellum, is started and after about 12 days an initial prodissoconch shell is formed, The umbo stage larva is initiated, in which umbones are formed. These larvae were matured, and after about 20 to 22 days, they were largely floated with a size of 240 ~ 280 ㎛ and had a ciliate and a pediveliger period where the foot and eye spots appeared clearly. For 2-3 days. After 23 ~ 25 days after fertilization, it attaches to the substrate such as palm or radial nets, and lives as attached scab.

Therefore, it is ideal to enter the grape harvesting period before the 23 ~ 25 days when the larvae appear 50% of the emergence of the foot. It should be kept indoors for 15 ~ 20 days when the shell is formed and the water should be returned two times a day (1/3 each) for about 2 hours and the water tank should not be moved.

It should be observed under a microscope daily for 15-20 days after sowing. The average height of the scallop must be 450 μm or more, and it should be stable. If microscopic observation confirms shell formation, the graft should be prepared.

After 15 ~ 20 days, the temperature is lowered by 1 ℃ per day by sea water temperature. It should be noted that it is necessary to confirm that the attachment state and the spatula are stable, for example, the skin is formed. The adhered larvae begin to transform, velum disappears, gills appear, and a new shell (dissocch shell) is formed on the apical region. When the size reaches 6 ~ 10mm, I go in.

The purpose of the middle management of the sprouts grown after grafting and grafting is to control the growth rate of juvenile spots adhered to the summer in high temperature, low salt, decrease of dissolved oxygen, increase of chemical oxygen demand (COD) , It is aimed to improve the survival rate of the spore by selecting and managing the spore, and to protect the young spore from the starfish such as the pirate creature and to nurture it as a healthy spore.

It is appropriate that the sponge for dispersing is about 8 ~ 12㎜ in length. If the sponge is not collected at the bandit, the starfish living together in the stunt may grow to a size that can be eaten by the participant. This food competition hinders the growth of the spatula, and the spatula that has been removed from the attachment is accumulated on the bottom of the poor environment, and the dead or the deformed or the growth is decreased.

Growth should be promoted to a healthy middle lard of 3 ~ 5㎝ in size within a short period of time by dispersing and managing low-density rootstock, which is a high growth period. Participation Liby middle paddle is highly resistant to high temperature, air exposure or fresh water, so it is best to start the day early in the day with a cool early dawn and finish the selection before 12:00 am. shall. The juveniles one year old will reach 6cm in length, reach 10 ~ 11cm (weight 100 ~ 150g) after 2 years and 12 ~ 14cm (150 ~ 300g in weight) after 3 years It grows up to 10 years and reaches 20cm (1kg weight).

Consumption increased nationwide due to the success of the riding style on the east coast, and it was popular as a tourist product. However, after 1997, 1,400 tons of production has been reduced to less than 600 tons due to large-scale mortality, This became difficult.

Also, due to lack of the amount of mulching in 1999, the production of sparrows was extremely low to 9,088 thousand compared to 110,000 in 1998, and there was concern about the supply of seedlings by natural seedling.

Participation Liby has contributed greatly to the increase of income sources of aquaculture farmers as a major varieties of East Coast with high value added, especially in Gangwon Province. Recently, due to instability such as marine conditions, cultivation efficiency has been low, to be. Therefore, first of all, it is necessary to secure a good and stable captain by constantly finding out the appropriate environment area that can induce maturation in the domestic farm and concentrating the group of mothers.

And, it is the most important task for participatory breeding industry to develop and distribute efficient seedling production technology to artificially mass-produce and supply quality seedlings by the technology of fishermen by their own techniques utilizing this mother-of-pearl.
