Description

Parasitic ciliary control integrated breeding system for dinoflagellates and shellfish larvae

The present invention relates to an integrated breeding system for parasitic ciliates controlling dinoflagellates and shellfish larvae, and more specifically, to cultivating and supplying dinoflagellates that kill ciliates that damage shellfish larvae and microalgae, which are food organisms for shellfish larvae. and, at the same time, an integrated breeding system for parasitic ciliary control dinoflagellates and shellfish larvae that can produce large quantities of healthy artificial shellfish seeds by rearing them in combination with shellfish larvae.

In shellfish farming, it is very important to secure a stable supply of seeds on a large scale. Methods for stably securing shellfish seeds can be broadly divided into methods using natural seedlings and methods of artificially producing them indoors. However, there are many difficulties in securing seeds through natural seedlings in sufficient quantities for farming due to various reasons such as environmental changes and lack of healthy seedling resources. Therefore, recently, after going through the process of mother rearing, spawning stimulation, and artificial insemination, hatched larvae are raised while continuously supplying appropriate food organisms, and a series of processes to secure seed shells for aquaculture are performed indoors. This indoor artificial seed production method is continuously increasing because it can produce more stably than natural seedlings, which are unstable and dependent on the natural environment.

The method of producing artificial shellfish seeds also has difficulties at each stage of the production process, especially in the mass culture process of microalgae used as food and the process of raising shellfish larvae. Factors that affect the mass culture process of microalgae include physical factors such as light, water temperature, and stirring, chemical factors such as salinity, nutrients, carbon dioxide, and hydrogen ion concentration, and mixing of predators, disease-causing organisms, and other organisms, etc. The same biological factors can be mentioned. These physical, chemical, and biological factors must be adjusted to suit the physiological characteristics of the microalgae to be cultured to successfully obtain a microalgae culture. In addition, in the shellfish larvae rearing process, there are physical factors such as water temperature and light, chemical factors such as salinity and dissolved oxygen, and biological factors such as predators and pathogenic organisms. Each of these factors must also be adjusted to suit the physiological characteristics of the shellfish larvae to be reared. It needs to be adjusted.

Meanwhile, when raising shellfish larvae, various types of diseases such as viruses, bacteria, and parasites occur, and the greatest damage is caused by species belonging to the subclass Scuticociliatia, which are parasitic ciliates. Among these ciliates, about 20 species are known as scuticoiliatosis, which parasitizes and causes damage to fish and crustaceans, and scuticiasis is one of the most damaging diseases among domestic farmed fish. However, not much is known about the ciliate species that infect floating larvae of shellfish and cause disease, but it is known that they occur in large numbers in the summer at many shellfish artificial seed production sites and cause the death of all floating larvae. Even though they are not disease-causing ciliates, species belonging to the Scuticosiliatia are distributed worldwide and include free-swimming species that feed on organic matter and bacteria. If ciliates occur in a floating shellfish larvae breeding tank, they affect the ciliary activity of the floating shellfish larvae, invade the helpless shellfish larvae, feed on the cell contents of the larvae, and reproduce explosively, ultimately leading to the failure of artificial seed production. . In order to reduce damage caused by ciliates, various types of chemical agents, such as formalin for fisheries, were administered at the aquaculture site, but they did not have sufficient effect. Instead, the damage was reduced to some extent by changing the number of animals raised every 2 to 3 days. . However, since it takes a lot of time and money to replace all of the breeding water, it is necessary to find a simple and economical method.

It was confirmed that some species of dinoflagellates living in the ocean are effective in killing scuticosiliatia, a parasitic ciliate (Korean Patent No. 10-1793393). In other words, if a certain amount of dinoflagellate culture or culture medium that kills parasitic ciliates is added to the shellfish larvae rearing tank and cultured, the growth of parasitic ciliates occurs without affecting the shellfish larvae or their prey. The inhibitory effect was confirmed.

Therefore, if shellfish larvae are reared while providing a constant supply of food for dinoflagellates and shellfish larvae, the development of parasitic ciliates can be suppressed and successful artificial seed production is possible. This makes it possible to feed dinoflagellates, plant prey, and shellfish larvae at the same time. There is a need to apply an integrated breeding system that can culture and raise.

The dinoflagellates culture unit 130 according to this embodiment serves to cultivate dinoflagellates by receiving seawater from the seawater storage tank 121. In this example, dinoflagellates include parasitic ciliate-controlling dinoflagellates, such as Alexandrium andersonii and Gambierdiscus jejuensis.

As mentioned above, since dinoflagellates grow slower than their prey organisms, which are microalgae (phytoplankton), contamination by other organisms frequently occurs and culture often fails. For this, sterilization of culture seawater is necessary and contaminants are introduced. You have to block it from happening. In addition, since a certain culture environment must be maintained to cultivate dinoflagellates, the material of the tank, filtration and sterilization of seawater and air, temperature and light intensity, etc. must be taken into consideration.

The dinoflagellate culture unit 130 includes a dinoflagellate culture tank 131 that receives seawater from the seawater storage tank 121 and cultivates dinoflagellates, and a first temperature sensor 132 provided inside the dinoflagellate culture tank 131. ), a first heater 133 provided inside the dinoflagellate culture tank 131, a second air treatment module 134 that filters and sterilizes the air supplied to the dinoflagellate culture tank 131, and a dinoflagellate culture tank 131.

Dinoflagellates cultured in the dinoflagellate culture tank 131 are supplied together with seawater to the shellfish larva rearing tank 151 of the shellfish larva rearing unit 150, which will be described later. Therefore, in order to facilitate the discharge of seawater containing dinoflagellates flowing out of the dinoflagellate culture tank 131, the bottom surface of the dinoflagellate culture tank 131 is formed in a cone shape with a concave center or the bottom surface is oriented from one side to the other. It may be formed to be inclined downward. Additionally, a pipe is installed to communicate with the bottom of the dinoflagellate culture tank (131), and seawater containing dinoflagellates is supplied to the shellfish larvae rearing tank (151) through the pipe.

Meanwhile, a filter tank (139) is installed on the bottom of the dinoflagellate culture tank (131) on the pipe connecting the dinoflagellate culture tank (131) and the shellfish larvae rearing tank (151) so that the dinoflagellate culture or dinoflagellate culture filtrate can be injected. ) is prepared. The mesh size of the filter tank 139 may be 50 ㎛ or 20 ㎛. When using Alexandrium andersonii, a parasitic ciliate-controlling dinoflagellate, a filter tank with a mesh size of 20 ㎛ is used, and when using Gambierdiscus jejuensis, a filter tank with a mesh size of 50 ㎛ is used. By using a phosphorus filter tank, it can be installed so that only the culture filtrate escapes without the cultures escaping.

And in order to cultivate dinoflagellates in the dinoflagellates culture tank 131, a constant culture environment must be maintained. In particular, the temperature, salinity, pH, carbon dioxide, and agitation of seawater must be kept constant.

In order to maintain a constant temperature in the dinoflagellate culture tank 131, the temperature of seawater stored inside the dinoflagellate culture tank 131 is controlled to be measured in real time using the first temperature sensor 132. And when the temperature of the seawater is below the set value, the first heater 133 immersed in the seawater in the dinoflagellate culture tank is operated to control the temperature of the seawater to reach the set value.

In addition, in order to keep the salinity of the seawater in the dinoflagellate culture tank 131 constant, the salinity of the seawater is measured in real time using the first salinity meter 138, and if the salinity of the seawater is below the set value, additional salinity is added. The salinity is supplied to reach the set value, and if the salinity exceeds the set value, seawater is supplied so that the salinity reaches the set value.

In addition, in order to keep the pH of the seawater constant in the dinoflagellate culture tank 131, the hydrogen ion concentration of the seawater is measured in real time using the first pH meter 137, and the pH of the seawater is below the set value or exceeds the set value. If it exceeds, it is controlled to reach the set value.

In addition, air must be supplied into the dinoflagellate culture tank 131 to maintain a constant amount of carbon dioxide supply and agitation. To this end, a first device capable of measuring the flow rate of air inside the dinoflagellate culture tank 131 in real time is required. An air flow meter (135) is provided. The first air flow rate meter 135 determines the air flow rate flowing into the dinoflagellate culture tank 131 through the second air blower 134a and the second air flow rate controller of the second air processing module 134, which will be described later, at a set value. Measures in real time whether it applies. And when the air flow rate supplied to the dinoflagellate culture tank 131 is less than or more than the set value, the dinoflagellate culture tank is adjusted by adjusting the second air blower 134a and the second air flow rate controller of the second air processing module 134. Adjust the supply amount of filtered and sterilized air supplied to (131) again.

In addition, the filtered and sterilized air is provided inside the dinoflagellate culture tank 131 and is sprayed into the seawater in the dinoflagellate culture tank 131 through the second sparger 134d immersed in seawater.

As described above, the air sequentially passes through the second air filter (134b) and the third ultraviolet sterilizer (134c) and then is sprayed into the seawater stored in the dinoflagellate culture tank (131) through the second sparger (134d).

In addition, since illumination light is required to cultivate dinoflagellates in the dinoflagellates culture tank 131, the first light source 136 is provided outside the dinoflagellates culture tank 131 to illuminate the dinoflagellates from the side of the dinoflagellates culture tank 131. Ensure that lighting is evenly illuminated inside the hair culture tank (131). To this end, as described above, the dinoflagellate culture tank 131 is made of transparent materials such as polycarbonate (PC), polyethylene (PE), and acrylic.

The first light source 136 uses an LED or fluorescent lamp to minimize heat generation, and the illuminance of the first light source 136 is set to 3000 Lux or more on the wall of the dinoflagellate culture tank 131. In addition, the illuminance of the illumination light irradiated to the wall of the dinoflagellate culture tank 131 can be measured in real time using the first photometer, and the illumination time of the first light source 136 can be controlled using the first light source controller.

The food culture unit 140 according to this embodiment serves to cultivate food organisms, which are microalgae (phytoplankton), by receiving seawater from the seawater storage tank 121.
