Description

[0001] Shellfish conditioning and depuration system with closed recirculation type [

The present invention relates to a method for inducing maturation of a gonad and inhibiting scattering of a germ in an indoor environment in order to obtain a fertilized egg necessary for seedling production during maturation or maturation of a target cultivar in the process of producing an artificial seed of biceps, , And a system to manage by circulation filtration system. In order to improve the food hygienic safety of the produced shellfish, it is caused by viruses such as Norovirus and Vibrio, which are likely to be contained in shellfish, and various microorganisms and metabolic processes of shellfish Which is capable of removing various kinds of foreign substances from the flue gas into a purifying device.

In general, the seedling required for shellfish production can be obtained through two methods of natural seedling production and artificial seedling production. Natural seedling production is a method of naturally producing seedling in the natural state, As the production volume is changing and the natural pollution and development of coastal waters has recently been worsened by the global warming, the place of natural pickling is decreasing every year. Therefore, not only is it difficult to secure the absolute demand quantity required, but also the natural seedling method There are also a lot of difficulties.

In order to solve the above problems, artificial seed production techniques capable of producing stable and good seedling have been developed for 30 years and industrialized globally. In the case of Korea, about 50 commercially available seed cultivars The production of artificial seeds such as oysters, eggshells, scallops, etc. is being produced in more than one billion pieces. The annual direct production amount is 20 billion Yuan, and the productivity of related derivative industry is over 100 billion Yuan. The industry is expanding.

The most important factor in the production of artificial seeds of shellfishes is to secure high quality embryos necessary for seedling production. The method of securing embryonic bolls of bivalves is to use natural matured individuals and artificially control the mother shellfish In recent years, techniques have been developed for the production of artificial seedlings during the year, and as the need for early seed production increases, it is common to mature shellfish early in the artificial maneuvering in the room before natural maturity. .

As described above, the management technique for artificially mollusking the shellfish in the room is to maintain the mother shellfish in the low temperature before the natural maturity and to induce the artificial maturation by continuously supplying the phytoplankton and the warm water produced in the room, , But the cost for the management of the shellfish is lower than that of the artificial seedlings because of the inefficient management of the warm sea water and low temperature seawater and food for breeding, It is more than 20% of the total operating expenses of cultivation area.

In other words, the large amount of feed water (warm water or low temperature seawater) used for the management of the mother shellfish and the abandonment of the food creature without being recovered makes it possible to reduce the energy cost required for maintaining the temperature of the rearing water, In order to solve these problems and to support the stable development of the artificial seed production industry as a whole, it is necessary to develop mature management techniques and devices that are more effective and environmentally friendly as well as capable of reducing energy consumption. .

On the other hand, recently, the shellfish produced in Korea has been contaminated with norovirus and the export to the United States has been stopped and the related industry has been seriously damaged. Also, some consumers who ingest domestic shellfish It has been reported that the production and supply of the shellfish which have secured the food hygienic safety has become a very important issue due to the various problems such as diarrhea and enteritis. The most important part is to develop a purification system for edible shellfish.

Until recently, shellfish purification technology has been applied mainly to filtering and disinfection of feed water in a shellfish breeding tank, while continuously removing harmful factors such as foreign substances, A large amount of energy is consumed for pumping and the removed foreign matter may be contained in the effluent to cause secondary environmental pollution in the nearby area. In this purification process, the weight of the shellfish body is reduced by 10% or more , And commercial producers such as mollusk has been a factor that deteriorates the purification process.

The bigger problem is that even if you take all these steps, you can not get stable purification treatment properly. This is a problem that occurs when the purification process is forcibly performed without taking into consideration the physiological condition of the shellfish. The development of a system that can purify the shellfish in a more stable and efficient way is the most important issue in order to ensure the continuous development of the related industries and the safety of the consumers.
