Description

[0001] The present invention relates to a method for breeding of good quality oysters,

The present invention relates to a method of producing high quality oysters, and more particularly, to a method of producing high quality oysters, The present invention relates to a method of producing high quality oysters.

Oysters are widely distributed all over the world and there are many kinds of foods that everyone likes. It is a major target for distribution in all coastal areas in Korea, and it is also attracting attention as a major export item.

This type of oysters is different from farming on land. Rice, barley, and other crops absorb the nutrients of the surrounding land (land) as roots, but when the oysters and sea urchins cultivated in the sea are raised, the food moves along with the birds. .

However, the existing oyster farms often select fisheries without considering the environment of the waters affecting the production of oysters, and the oysters are killed or produced with high quality oysters And the productivity of the oysters is lowered.

≪ Embodiment 1 >

1 is a flow chart showing a method for producing a high quality oyster according to a first embodiment of the present invention.

First, in a first step (S110), the environment of a sea area for culturing oysters is grasped. Specifically, the environment of the sea area is determined by examining at least one of the specific gravity of the sea area, the amount of plankton, and the amount of injected seawater. The specific gravity, amount of plankton, and amount of feed water are closely related to each other. Areas with low specific gravity are areas where there is a lot of infusion of land water on land. Therefore, there are many influx of nutrients. On the other hand, in areas with high specific gravity, inflow of nutrients and inflow of nutrients into the ground is small. Nitrogen content is abundant in the place where the amount of feed water is high, and this is the feed of plankton, meaning that the area with low specific gravity is rich in plankton. The amount of plankton affects the growth of oysters, since plankton is the food of oysters. Therefore, one or more of the amount of plankton, the specific gravity, and the amount of injected water should be investigated in order to identify the sea area capable of producing oysters.

Next, in a second step (S120), a fishing grounded area is selected based on the environment of the sea area examined above. Specifically, the fishery site area for the oyster culture is selected based on the specific gravity of the sea area, the amount of plankton, and the amount of water injected in the first step.

In the present invention, the difference in the specific gravity of the sea area is divided into subdivisions. If the specific gravity exceeds 1.027, it is determined that the specific gravity is high. If the specific gravity is between 1.024 and 1.027, it is determined that the specific gravity is intermediate. If the specific gravity is less than 1.024, When the amount of plankton in the area with high specific gravity is expressed as 1, the amount of plankton is in the range of 6 to 20 times in the area having a specific gravity, and the amount of plankton is 20 to 100 times when it is less than 1.024. The larger the amount of plankton, the better the environment for producing oysters. However, if the amount of plankton is too large, the amount of pirate creatures increases rapidly. Therefore, caution should be exercised in coastal areas where the amount of plankton is more than 50 times.

Next, in a third step (S130), a moving form method is applied according to the environment of the selected fishing ground area. The mobile culture method is a way to produce high quality oysters by giving environmental changes to oysters when culturing oysters. When the oysters undergo environmental changes, they become breeders. In other words, when a large amount of food is consumed and a certain degree of obesity occurs, eggs or semen will be made in the body to cause irritation to achieve the purpose of breeding. The mobile culture method uses the habits of these oysters.

* In areas with low specific gravity, there are many nutrients and plankton, which is good for meat quality obesity. Particularly, when the flow rate is high, each part and meat quality grow at the same time. However, when there are problems such as occurrence of red tide due to high water temperature or low specific gravity in the environment of the sea, the reproduction of the breed occurs suddenly, There is a risk of our death. In areas with moderate specific gravity, the yield depends on the flow rate, but in autumn, the angle is large and the quality of the oysters is also good, producing high quality oysters. In regions with high weight, oyster meat is less obese. Especially, where the flow rate is moderate, the productivity of oyster with high mass is low, and when there is a small amount of egg scattering and low fertilization rate, the oyster health is not greatly deteriorated and it is a good fishing ground.

Table 1 below is attached to compare the growth of oysters with specific gravity.

By sea area (specific gravity) Each growth (year) Meat quality obesity Monthly Waste Forran spawning Above 1.027 7 ~ 8cm 30 to 40% Around 10% 50% 30% 1.024 to 1.027 7 ~ 8cm 40 to 70% Around 30% 70% 50% Less than 1.024 7 ~ 8cm 70 to 90% Around 90% 90% 90%

As shown in Table 1 above, the growth rate of oyster shells is not significantly influenced by the difference in specific gravity, but the degree of fatness of meat varies greatly depending on the specific gravity. Therefore, a mobile culture method is required to meet the growth rate of shell and meat quality.

In the case of the mobile culture method, the oysters which are under obesity are harvested, and the oysters which are large and weak in meat size are harvested and separated into individual lobes and moved to a region with low specific gravity. The oysters moved to areas with low specific gravity are undergoing environmental changes due to differences in specific gravity, food quantity, water temperature, and flow rate, and they start their behavior life of racial breeding. In addition, when the water temperature is around 18 ℃, high quality oysters with over 90% of meat quality are produced. That is, when the oyster is scattered at a temperature of 24 to 26 ° C, oyster does not occur when the water temperature is below 18 ° C, and only obesity of the meat is formed.

It is also referred to as the Shotk cultivation method because it is a method to make the oysters grow by giving a shot to the oysters with these environmental changes.

Therefore, by referring to Table 1, it is possible to improve the productivity and quality of oysters by applying the mobile culture method in accordance with the own fishery environment.

Next, in a fourth step (S140), a concrete format condition for the oyster style is determined. The specific culture conditions are determined by including at least one of the number of days, the number of years of water storage, and the interval of the water bottom. The oysters' seedlings have 2-year-old seedlings suppressed and suppressed in the following year, and early-seedlings dwarfed in June and July. When they are taken together, It is important to recognize that the health of the oyster itself (mulberry) becomes very weak due to the occurrence of the oyster, and massive deaths due to the occurrence of weak red tide. .

In the oyster cultivation, the lower part of the stem refers to the line when the oyster shells are sewn on the strings and placed under the water to grow the seeds. As described above, the number of plankton varies greatly depending on the sea area depending on the specific gravity difference. If there are many plankton, there are many pirate creatures who eat plankton, so if oysters do not form a certain group, they can not be suppressed in survival competition. Therefore, it is important to adjust the spacing between the subsidence and the bottom of the water in the oyster culture.

(100 m X 100 m) according to the specific gravity of the sea area are shown in Table 2 below.

importance Subsidized training per hectare Over 1.027 (high) 3000 ~ 4000 years 1.024 to 1.027 (medium) 4000 to 6000 years Less than 1.024 (low) 6000 ~ 8000 year

As shown in Table 2 above, in the case of a sea area having a high specific gravity, it is preferable to set the number of years of harvesting per hectare from 3000 to 4000. If the number of years of water storage exceeds 4,000 years, the distance between the water bottoms becomes too narrow to inhibit the flow of birds. If the water storage capacity is less than 3,000 years, the amount of water to be harvested will be too small.

In areas with moderate specific gravity, the number of undersea per hectare should be 4,000 to 6,000. Since the number of plankton is higher than that of high density area, it needs to be formed with a group in order to prepare against pirate creatures. At this time, if the loading period exceeds 6000 years, the bird traffic is inhibited. If the loading period is less than 4000 years, it is difficult to form a group to prepare for the pirate creature and the yield is decreased. Therefore, It is recommended to set it from 4000 to 6000 years.

In areas with a low specific gravity, the number of subsea per hectare is adjusted to 6000 to 8000 stations. Since the number of plankton is considerably increased in areas with low specific gravity, oysters should be formed with a group of oysters in order to prepare pirate creatures. At this time, if the water storage period exceeds 8000 years, it will interfere with the flow of birds. If it is only 6000 years old, there will be difficulty in forming the group to prepare for the pirate life and the yield will be lowered. Therefore, Is set to 6,000 to 8,000 years. In areas with low specific gravity, increasing the number of soft-bridges in this way can result in growth and fullness of legs and meat at the same time even if the interval is narrowed.

 In conclusion, in order to cultivate high-quality oysters, it is necessary to grasp the environment of the sea area to cultivate oysters and to determine the spacing between the main and lower hydrangeas according to the specific gravity of seawater and the content of plankton, You can detect success.
