How to farm worms {Method Of Cultivating Lugworm}

The present invention relates to a worm farming method, it is possible to prevent the fertilized egg to be contaminated or dead by spawning and poaching while flowing sea water, and to naturally fertilize without separate process to prevent damage to the fertilized egg during spawning and poaching process It is possible to discharge the protozoa with the seawater during the incubation process, and to the worm farming method to prevent the damage to the breeding environment during the drainage of seawater.

Tidal-flats are places of spawning of marine organisms and are a primary food supplier, and at the same time cleanse various environmental pollutions. However, the random catching of resources, which ignores the potential productivity of resources, causes the tidal flats, which are representative of the tidal flats, to disappear. This is due to the deterioration of the tidal flats, which accelerates environmental pollution and threatens the coastal ecosystems, resulting in red tide occurrences and a decrease in income of fish and shellfish. It is shrinking.

The earthworm is an organism that has excellent tidal-cleaning ability by changing the organic composition of the tidal flats by making habitats in the tidal flats, occupies a very important position in the marine benthic ecosystem, and is used as an indicator organism of marine pollution and at the same time, it is the main food for benthic fish. And fishing bait has become a target of fishermen side business.

The fishing industry in modern Korea is close to the offshore fishing industry, and the main source of income is mainly from fish farming and shellfish farming. Fish farming is in difficult times due to huge facility cost, feed price, labor shortage, and price drop due to the increase of imported fish. And most fish farmers suffer from large debts. Shellfish farming is also very difficult due to the recent decrease in unit productivity due to imports and environmental problems.

However, given the fact that demand for fishing lures is rapidly increasing due to the introduction of a five-day system and a rapid increase in the fishing leisure population, the necessity to cope with the demand with full-scale domestic supply using artificial worm artificial seedlings is raised. In addition, it is expected to increase income of aquaculture farmers and export abroad, and to expect the effect of trillion tides of environment conservation of tidal flats.

And since the future of abalone seedling production industry is not bright, the worm farming method can utilize all the abalone facilities as it is trying to switch to other varieties, and it can be said to be a very useful farming business for aging fish.

Currently, about 80% of the total domestic consumption of lugworms is dependent on imports, mainly from China and Vietnam. In the past, countries with a large fishing population, such as Japan, the United Kingdom, Australia, and France, have few tidal flats, so most of them are imported from Korea, China, and Vietnam. Korea has ceased exports since 1990 due to resource depletion, and China is also in danger of depleting the worms in 2010-2015 due to its heavy fishing population, environmental pollution and industrialization. Therefore, many countries are doing a lot of research to breed worms.

However, the lack of research on aquaculture methods resulted in the death or damage of the worm fertilized egg during the aquaculture process, and the success rate was not very high in the process of growing into an adult.

The method for farming worms according to the present invention proposed to solve the above problems comprises the steps of spawning and spawning, hatching, breeding the hatched larvae as worms, and breeding the worms as adults In lug farming method; In the spawning step, the male and female caterpillars are put into a container filled with seawater, supply air, and maintain the water temperature in the range of 18-25 ° C. Scattering while continuing to drain the seawater by draining, and scattering the worms eggs spawned by the mesh provided to the upper portion of the drain pipe.

The step of hatching is to maintain the water temperature in the range of 18 to 22 ℃, to supply air, to supply the seawater from one side supply pipe and to drain the bottom drain pipe at least once a day, and to the inlet side of the drainage pipe It is characterized in that the size of the eyes of 70 ~ 90㎛ is installed to incubate while washing the fertilized egg.

In the breeding step, the larvae grown and hatched by the worms form a breeding soil layer on the bottom, and maintain the height of the seawater in the range of 3 to 5 cm above the breeding soil layer, and the temperature of the seawater 21 Maintain in the range of ~ 28 ℃ and supply air, the upper part of the breeding soil layer is inclined downward toward the drainage pipe, install a drain pipe extending through the breeding soil layer to the upper part of the breeding soil layer once a day through the drain pipe It is characterized by replacing the sea water by draining the sea water.

In the breeding of the worms in the adult to form a loess layer on the bottom of the breeding tank body, to form a breeding soil layer made of sand to the top of the ocher layer, supplying seawater to the top of the breeding soil layer and supplying air to seawater Maintain the temperature of the seawater in the range of 21 ~ 28 ℃, once per day through the ocher layer and breeding soil layer through the drain pipe installed to extend to the upper part of the breeding soil layer while replacing the larvae and breeding adult It is done.

According to the lugworm farming method according to the present invention, while the male and female caterpillars feed and supply air, while installing the net 107 in the upper portion of the drainage while supplying seawater and draining to the bottom and scattering the seawater while flowing seawater in the container and Because the eggs are laid, the fertilized eggs can be prevented from being contaminated or killed by various protozoa or viruses, and the fertilized eggs can be collected and harvested naturally in the net 107 with the water of the sea. It is possible to prevent the fertilized egg from being damaged, and by installing a mesh with a scale of 70 ~ 90㎛ on the inlet side of the drainage pipe and draining it while supplying seawater, the protists can be discharged together with the seawater during the incubation process. Drainage extends through the breeding soil layers 329 and 429 to the upper part of the breeding soil layers 329 and 429. By installing (331, 451) and draining through the drain pipes (331, 451), it is possible to prevent seawater from passing through the breeding soil layers (329, 429) to damage the holes formed in the breeding soil layers (329, 429), etc. It can be prevented to have an effect that can prevent the breeding environment is damaged by the drainage.
