Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to artificially adjusted fish and shell algae that live only in the aquatic sea, using artificially adjusted air and water, and plankton that has been generated and propagated semi-naturally. Performs seedling and cultivation (cultivation) of pearl mussels and other fish and shellfish.
The present invention relates to a method for artificial cultivation of pearl mussels on land using artificial air.

[0002]

2. Description of the Related Art Conventionally, seedlings are collected on land and aquaculture is carried out in the natural sea. However, seedlings are collected by completely filtering seawater and culturing fine plankton for seedlings. However, plankton is a microprotozoan protist, and its artificial cultivation is very cumbersome and difficult, and requires an experienced and technically trained technician.

[0003] And a large amount of culture must be used,
It requires a culture room with special facilities, and a large amount of ordinary expenses including labor costs.

[0004] In addition, the natural sea culture method involves laying a floating ball on a raft or rope in the sea, laying it fixedly with an anchor, and putting shells in a pearl net for aquaculture, thereby preventing disasters such as earthquakes, tsunamis, and heavy rains. There was no way to defend.

[0005] In the natural sea, when the seawater temperature falls below 15 ° C, plankton turns into spores and dives into the mud on the seabed to winter. The period is about six months from November to April of the following year. The pearl oysters are no longer nutritious and the cold has forced them to hibernate.

[0006] In addition, pearl oysters are organisms that do not inhabit unless they are in the aquatic waters of the inner bay, and the inner bay is in an environment that is poorly salted and easily polluted.
It is contaminated by herbicides, etc., and the contamination reaches the limit.
More than a percentage are dying, and the damage is expanding nationwide, from Mie Prefecture, the birthplace of pearl culture, to Uwajima, Shikoku, the largest producing prefecture, to Amakusa, Kyushu. The pearl farming business is now under crisis and the pearl industry, which is said to be a monopoly industry in Japan, is being dyed and the cloud is about to end.

[0007]

[Problems to be Solved] When cultivating plankton, cultivation facilities and equipment and materials, culture chemicals, electricity bills, labor costs, and other large expenses are required, and about 10 types of chemicals are used. Because of cultivation, phytotoxicity remains, and it is difficult to manage the artificial culture technology of plankton,
It requires specialized technicians, and furthermore, plankton has a sensitive condition response, and it cannot be said that it is extremely difficult to cultivate the target quantity completely due to a slight change, and stable supply was not possible.

The pearl oysters are organisms that cannot live without the air of the inner bay, and the inner bay is in an environment that is poorly tidal and easily polluted.
The pollution has reached its limit and more than 50% of the cultured shellfish are now dead.

[0009]

SUMMARY OF THE INVENTION The gist of the present invention is to perform seedling collection and artificial cultivation of pearl mussels and other fish and shellfish on land by air whose water quality is controlled to the same level as that of the natural environment. This is a land-based artificial cultivation method for pearl mussels or the like.

Next, the present invention will be described in detail below. I) Adjust the air quality to the same level as the quality of natural bay water. Today the natural seas are polluted, and with the decline of all fish and shellfish, many different species are cultivated by artificial seedlings and artificial culture. Of particular interest is seed collection, and the living body at the time of seed collection must be finely nutrient because it is very small. At present, seed collection is performed by artificially cultivating about 5μ of plankton. However, cultivation of this plankton is very difficult, and it requires a great deal of cost and labor. Therefore, when searching for a method of cultivating plankton, I found out and looked at the bacteria contained in a large amount in river water. The bacteria have the following characteristics. (A) Bacteria are milk-like nutrients at the time of germination of phytoplankton and seaweeds. (B) Bacteria play a major role in maintaining and preserving ecosystems by decomposing, digesting and absorbing food as intestinal bacteria in animals. (C) Bacteria are purifying the environment. The introduction and adoption of bacteria has completely eliminated the need for nutrients (chemicals) required for culturing plankton. The introduction and adoption of bacteria eliminates the need for any chemicals or the like for cultivation of plankton, and has completely eliminated the risk of phytotoxicity and sequelae. The introduction of bacteria has reduced the special culture room, equipment and materials, all chemicals, and labor costs required for cultivation of plankton. II) About the water regulation tank * (The gas water is the seawater that has been reduced in salt due to the mixing of seawater and freshwater, and the estuary of the inner bay etc.) (a) Approximately 80% of Pacific seawater + approx. % Water taken. (B) Adjust the salt concentration to about 21 ° C. (Pacific seawater is 35 ° C) (c) Set the seawater temperature to 22-23 ° C by means of a heater / cooler (cooling down in summer-heating up in winter). (D) The air and water are well stirred and fluidized to promote oxygen absorption. (E) PH and the sea have been around for over a billion years since the creation of the earth, and they remain unchanged unless they are polluted. PH8 has been sustained by natural providence, so don't worry. (F) However, it shall be measured and recorded daily based on the observation rules. (G) Under conditions close to the natural environment, release water with controlled water quality into the plankton breeding tank. III) Plankton breeding tank * (plankton is divided and propagated by photosynthesis) * (light required for plankton multiplication is sufficient to be propagated by fluorescent light even if it is not sunlight) * (natural sea) * Plankton is a valuable plant that divides and proliferates about 2-3 times a day. * (Phytoplankton is a valuable plant that inhales carbon dioxide in the sea together with seagrass and discharges oxygen.) * The optimal plankton is phytoplankton. (B) Irradiate a light beam of about 10,000 lux day and night.
(10,000 lux is the daytime light on a clear sunny day with no clouds in autumn). (B) The air-water temperature is set to 22-23 ° C. by a warm / cooler. (C) By air blowing, air and water are well stirred and flow to promote oxygen absorption. (Seawater does not absorb oxygen more than about 80% of fresh water.) (D) Set the salt concentration to 21 ° C. (When the salinity is set to 21 ° C, a large amount of plankton called skeletonema, which is optimal for pearl mussels, is generated.) (Tested in our laboratory in artificial culture tests.) (E) PH is as described above. . (F) Bacteria and minerals in river water + All nutrients in seawater and + Qualified environmental conditions are optimal = Optimal mass production of plankton (G) As in the past unpolluted natural sea, no plankton Proliferate. (H) Thoroughly pursued the rules and principles of nature and succeeded in spontaneously growing plankton. (The only difference from nature is the rays of sunlight and fluorescent lights.) (I) After securing the number of pearl mussels × the required number of plankton, release them into the culture tank. * Estimation of the annual growth rate of plankton for the natural sea and this method shows that this method has a high efficiency of 1216%. See Table 5 IV) About aquaculture tanks Omitted this section V) About seedling * Since this facility can control the temperature freely, it is possible to harvest seedlings at any time of the year, regardless of the season. it can. * You can harvest seeds without any medicine or feed. It is the revival of the seedling method in the natural sea. * Seed harvesting method using cedar branches and leaves was developed by Iku in July 1947. * Explain in detail how to harvest seedlings. (A) When the seedlings are to be harvested, the temperature of the mother mussel culture tank should be 1
Raise by about ℃ and raise to about 30 ℃. (B) Observe the state of the eggs of the shellfish every day. (C) The ovaries are spreading on the bread. (D) Prepare cedar branches and leaves. (Don't cut the branch as it is.) (E) The drainage from the mother mussel cultivation tank is returned to the seedling tub. (F) 70% of nutrient air and 30% of drainage from the shellfish tank are fed to the seedling tank. (G) The color of seawater in the mother shellfish culture tank changes to yellow due to ovulation. (H) Confirm ovulation, immediately reach, throw cedar branches and leaves into the seedling tank. (In this case, insert the cedar leaves so that the bottom of the tub is not visible.) (Sperm and eggs are instinctively floating in the sea in search of dark places.) The temperature is gradually returned to 23 ° C. (Nu) After about 10 days, the attachment of juvenile shellfish to the underside of the cedar leaves can be visually confirmed. (R) Stop water supply from the drainage basin. (E) Switch to total nutrient water. (W) The attached juvenile shellfish crawls on the upper surface of the cedar leaves in search of light. (This is an instinctual action.) (F) When the larvae reach about 1 cm, collect them and house them in lanterns for aquaculture. (G) If the expected number of juvenile shellfish has not been collected, repeat after 2 months. * Successfully harvested seeds without any medicine, no feed, and no harm by properly adjusted air and water. It is a restoration and reconstruction of the past unpolluted aquatic sea area. VI) About Pacific Seawater Seawater is composed of all the elements that are necessary for the reproduction of animals and plants, in which every element of the earth is dissolved. VII) River water River water contains a large amount of bacteria and minerals which are basically required for the reproduction of animals and plants. VIII) Annual aquaculture efficiency When the annual aquaculture efficiency of the natural sea culture method and this method is estimated, this method shows a high efficiency of 362%. See Table 6

[Table 1]

[0011] Seawater is taken in by the seawater intake pump of
The river water is taken in by the river water intake pump, and the water is adjusted by sending it to the air water adjustment tank. The water is supplied to the plankton breeding tank to measure the growth of plankton. Water supply and aquaculture.

[Table 7]

A photograph of a pearl mussel that has been cultured in air water with a 10 mm nucleus inserted. Plankton artificially cultivated with no medicine and no feed using fluorescent light rays * By completely converting the facility to a factory on land, it is possible to take all possible measures against disasters. * When cultivating fish and shellfish in an aquarium, the biggest problem is the removal of manure, but as shown in Table 3, it is made so that manure can easily accumulate. , Preventing the oxidation of seawater. In this method, the amount of excrement collected is small because the system is automatically drained as the seawater flows in, and the degree of metabolism is high, so that the oxidation of seawater can be completely protected. * The root of the growth of living things is intestinal bacteria (bacteria). If the intestinal bacteria do not work properly, no matter how much nutrients are given, the shellfish will not grow or grow and the pearls will not roll. With the introduction of river water, abundant bacteria are secured and the shellfish grows and grows soundly and well, the pearls roll faster and the shellfish do not die. * The natural sea has been artificially contaminated, and more than 50% of cultured shellfish have died. * Living things are not easy to die if environmental conditions and nutritional conditions are good. The mortality rate of Japanese is 6% because of good environment and nutritional condition. (Excluding traffic accident deaths, accident deaths, and senescence deaths) (Ministry of Health and Welfare data) In the 1950s, when the sea was not polluted, the mortality rate was less than 10%, even if growth was poor. * Indoor temperature, seawater temperature, salt concentration, dissolved oxygen, PH,
It is farmed under computer control with thorough consideration of thorough adjustments such as the degree of water exchange, seawater flow, and the flow near plankton. * The shellfish grows 365 days without hibernation because of the room temperature facility. * Introduced Pacific seawater and unpolluted river water, and succeeded in regulating air quality exactly the same as natural sea air, making it drug-free. Large amounts of plankton spontaneously developed and proliferated without feed. * In addition, the fact that seedlings can be collected without any medicine or feed is a big harvest and a step forward. * As a result of the successful seed collection, all the raw materials required for production, except for the core, became self-sufficient. * Since this facility is at room temperature, all pearl culture processes can be carried out systematically at any time, regardless of the season or season. * The larvae and mother oysters have good environment, good nutrition, good growth and growth, and 20-25 momme 40-50 hooks (the hook means the number of shells per pier) 10mm nucleus can be inserted easily. The 11-12mm large ball was completed in 5 months and succeeded in the double cropping of the large ball. (It takes 1-2 years for the natural sea culture method.) (The use of the shakukan method is permitted for pearls.) * The profitability is outstanding, and the ordinary expenses should be within 30%. * With this aquaculture method, long-term aquaculture business can be continued as long as the rivers withdrawing water are not contaminated.

[0018]

According to the present invention, since the present invention is completely the same in quality as the natural sea water, seedling and cultivation of fish and shellfish such as pearl mussels can be performed without any medicine, no feed, and no harm, resulting in large cost savings. Periodical,
It is a great place to contribute to the industry.

The present invention also provides a complete plantation on land, which accurately generates and proliferates defense plankton against oxygen supply and a decrease in PH, and provides thorough management of environmental water and proper feeding of shellfish to achieve healthy growth of shellfish. And helped reduce mortality.

* In addition, since the onshore aquaculture method of the present invention is completely factory-based on land, defense and defense such as natural disasters are perfect,
Because of the normal temperature (22-23 ° C) throughout the year, hibernation of the shellfish was eliminated for about 6 months, and the shellfish grew and grew throughout the year.

Next, the present invention will be described in detail below. * Nature's Providence and Principles (Hints) Seawater and river water (including lakes and ponds) on the earth are eternal and immutable since the creation of the earth, without the involvement of human beings. The environment necessary for the reproduction of tens of thousands of valuable aquatic plants and animals, the pH 8 conditions, etc., and the basic nutrients such as plankton are spontaneously and stably bred. It is nature's providence and principles that have sustained our natural environment. (If humanity does not pollute,
(The natural environment was eternal and immortal.) 1, In seawater, every element on the earth is dissolved,
Optimum conditions are maintained for the maintenance of aquatic ecosystems. 2. River water also contains nutrients similar to seawater,
In particular, it contains about 300,000 bacteria per ml (1 CC) and a large amount of minerals. B. Bacteria are a valuable milk nutrient at the time of germination and growth of plankton. B. Bacteria are purifying the environment. C. Bacteria exist as intestinal bacteria in all animals and play a tremendous role in the maintenance and preservation of living organisms by decomposing, digesting and absorbing food. D and minerals are basic elements necessary for the maintenance and preservation of animal ecosystems. 1) Artificial aquaculture method This aquaculture method is a system that precisely pursues and applies the principles and principles of nature, and artificially mixes and mixes external seawater and river water on land to produce natural seawater water. The artificial cultivation of all seafood algae inhabiting the aquatic sea area is performed on land by artificial air of the same quality. I. Plankton naturally occurs in large quantities due to normal temperature and light irradiation throughout the year. II and PH are the same quality as natural seawater, so they maintain and maintain a stable environment. III. It is a non-medicated and no-feed artificial terrestrial aquaculture method. 2) Location conditions I. It must be a junction between the open sea and the river. II. Avoid areas around large cities and large industrial areas. III. Aquatic flora and fauna inhabit the river from which water is taken. 3) Water intake By pumping up, water is taken into the air-conditioning tank of the onshore facility. I, about 80% of outside seawater (not contaminated) II, about 20% of river water (each) 4) Steam control tank (adjustment of specific gravity) Steam water is low due to mixing of seawater and fresh water. Seawater from salted inner bays and estuaries. I. In this tank, the mixing of outside seawater and river water is adjusted, and the specific gravity of air water adapted to the culture is adjusted. II. There are many seafood algae that live only in aquatic fishing grounds. III, pearl mussels are representative of those that live only in aquatic fishing grounds. 5) Plankton breeding tank Plankton divides and proliferates by photosynthesis, so it emits a light beam of about 10,000 lux day and night. (10,000 lux is the daytime light on a fine autumn day) b. Plankton in this breeding tank repeats about ten times in 24 hours, dividing and growing throughout the year. B. Plankton in the natural sea is dividing and proliferating about two to three times a day. (However, for about 6 months per year) 6) Plankton optimal for pearl mussels The type and quantity of plankton greatly depends on salinity, seawater temperature, nutrients, etc. I. In the sea area near the bay mouth where seawater specific gravity and seawater temperature are high, the occurrence of plankton of the keitocellos type occupies the mainstream. II, When the temperature of air and water is 23 ° C and the specific gravity is about 21 ° C,
The predominance of skeletons is plankton, which is most suitable for pearl mussels. III. Pearl pearls vary greatly in the color, luster and value of the pearls that are born depending on the type of plankton they eat. If the former is eaten, many golden pearls are born. If the latter is eaten, high quality white / pink pearls are produced. IV, These facts are based on the origin of cultured pearls, the type of plankton that occurs at the mouth of the agogo bay in Mie Prefecture,
It is actually proved by the results such as the difference of pearls. 7) Culture tank (tub) 5) In the plankton breeding tank of 5), the multiplied nutrient water is released into the culture tub, and cultivation of pearl mussels and seedling are performed. 8) Nutrition (plankton) I. The daily amount of plankton released is about 100 million or more per adult shellfish. 9) Tidal current (metabolism) I. Tidal current in the aquaculture method according to this method is a one-way system.
All air is exchanged for fresh air in about 8 hours. II. The daily amount of tidal current (nutritive water) passing through the culture tub is
Approximately 70 l per adult clam. III. As mentioned above, the metabolism is sufficient and the environment is almost perfect. 10) Specific gravity (salinity) I, the specific gravity of seawater is measured while keeping the seawater temperature at 15 ° C. II, specific gravity varies with its temperature relative to water. III, the specific gravity is measured with a Baume meter and read with an Akanuma conversion table. The optimum air temperature and specific gravity for IV and pearl oysters may be generally as follows. Air-water temperature Baume measurement specific gravity Converted specific gravity 23, 00 ° C 21.00 ° C 22.79 ° C V, the water-water specific gravity adapted to the type of aquaculture is adjusted in the air-water adjusting tank by adjusting the mixing ratio of river water. I do. 11) PH The aquaculture method according to this method is based on the uncontaminated natural sea (open sea).
Seawater and river water are artificially air-conditioned on land, and as a tide flow path, the land is only detoured by the bypass,
It is completely the same quality as the clean air of the natural sea.
H is about 8, which constitutes an optimum condition. 12) Set temperature of air water The air temperature of all facilities is set to about 23 ° C at normal temperature by heating and cooling in a high temperature season and heating in a cold season by a hot / cooling machine. I. However, the following cases are dealt with by a necessary appropriate temperature. B. Tailoring (egg removal) 23-33 ° C b. Seedling 23-33 ° C c. Cosmetic winding (finishing) 10-23 ° C 13) Supply of oxygen (stirring and flow of air) I. Seawater is fresh water 80 % Do not absorb oxygen. II. An air blower is installed in all tanks to supply oxygen strongly. III. The facility is designed so that the steam and water of all facilities are stirred and flowed universally so as not to stay or stagnate. 14) Indoor temperature In each room, an air conditioner is installed to prevent the water temperature from changing, and the room is adapted to the adaptive temperature. 15) Filtration of air I, pearl mussels have no teeth and tongue, so even if they are nutritional, they cannot be eaten. II. Therefore, it is necessary to remove large sludge and dust. III. Adults usually eat 15-30μ of plankton. IV, place a filtration device within 50μ. V. By the above, it is possible to promote the growth and growth of the shellfish and improve the culturing efficiency. 16) Water quality Artificial steam according to the present method ranks higher than natural seawater. I, air and water are clean. II. At room temperature, pearl mussels do not hibernate and grow year-round. III. Plankton grows all day and night by irradiation of room temperature and light. IV. The tidal current is a one-way system. The whole amount of air is exchanged with fresh water in about 8 hours, and the metabolism is good. Aquaculture efficiency has been doubled. 17) Shellfish cleaning I. In the current natural sea culture method, bad bacteria are abnormally generated due to contamination, contributing to soiling of the shellfish, and foreign substances not seen in the past adhere to the entire surface of the shellfish. It is so dirty that it cannot breathe, it inhibits the growth of shellfish and induces death. B) In recent years, shellfish will die unless they are cleaned in about seven days. B. Therefore, a lot of extra labor costs are required. II. In the culture method according to the present method, the shellfish is little stained due to clean air, and cleaning of the shellfish may be performed once every two to three months. B. It returned to the exact same state as the natural sea culture method of the 1955s. III. Aquatic organisms are usually not very dirty if the water environment is clean. A. In the 1950s, a diver dived to a depth of about 10 meters below sea level. IV, pearl mussels are strongly attached to rocks and the like by the feet of ground hair, and if the environment and the nutritional state are good, they will spend their entire lives as they are. When cleaning shellfish, do not cut the ground hair as much as possible. B. Because you need extra energy to get the ground hair back. 18) Facility cleaning Carefully observe each facility for dirt and clean it appropriately. B. Clean the culture tub especially patiently. (2) The sludge and dust are removed from the air-conditioning tank and the plankton breeding tank by a tank bottom cleaner as needed. (C) Open and close the valve of the sludge reservoir to remove sludge. 19) Elimination of hibernation I. Plankton, when the seawater temperature is below 15 ℃
As spores, they dive into the mud on the sea floor and winter. B) The pearl mussel hibernates constantly due to the lack of nutrition and the cold temperature. B. Hibernation period, about 6 from November to April of the following year
In months, the shellfish have stopped growing. II. In this method, the shellfish grows well due to the normal temperature throughout the year, and has achieved more than 300% of the results compared to the natural sea culture method. III. Normally, animals do not hibernate if the environment and nutritional state are good. (At Higashiyama Zoo, Nagoya) 20) Deterring I. Under the current natural sea culture method, the sea is polluted on a nationwide scale and more than 50% of shellfish are killed. II. Animals usually do not easily die if the environment and nutrition balance are good. III In the present method, the mortality rate including poor growth is about 8%. IV, about the same level as natural sea cultivation around 1955, it is a revival of clean air fishery. V. Incidentally, the mortality rate of Japanese is 6%. (According to the Ministry of Health and Welfare statistics) (Excluding accidental death and senescence) 21) Production of golden pearls I. In the past, golden pearls have no value as pearls.
It was treated like a junk ball and it was a cat straddle. II. The pearls are in the spotlight these days, are gold rushed and are traded at high prices as excellent products. III. Improvement of pearl processing technology has made it possible to perform decolorization and dyeing, and in particular to be able to process pearls of excellent quality. If you want to produce IV, golden pearls, this method can do it easily. B. If the air temperature is high and the specific gravity is high, golden pearls can be produced. (Refer to the plankton that is most suitable for the 6 pearl oysters.) 22) Installation of spare equipment In anticipation that the function will be stopped due to failure of main equipment, etc., be sure to install spare equipment for the following equipment. Corresponding. B) Intake pump b, air blower, heating / cooling unit, filter e, air conditioner 23) Emergency response I, pearl mussels have the strongest vitality among seafood. II. Even if there is no seawater, about 50 hours will not die unless the body surface is dried. III. If the operation of machinery is stopped due to an accident or the like, the equipment will be responded to by private power generation. IV In the event of an accident, shut off the stop valve to stop the inflow of air from the aquaculture tank. V. The air blowers in all facilities are operated by private power generation, and an emergency can be avoided if oxygen is supplied and steam and water are well stirred and flown. VI, disasters and accidents cannot be predicted, so a start-up operation test of the private power generator is performed at least twice in the morning and evening each day. VII In the current electricity situation, the power outage will recover in 5 hours unless a catastrophe occurs. VIII, Response to long-term power outages. B) If a power outage is expected for more than 5 hours, drain all the water from the culture tub. B. Every 3 hours after draining the water, remove the water from the water adjustment tank or plankton breeding tank using a watering hose. If you moisten the surface of the shellfish, the shellfish will not die for about 50 hours, so wait for the accident to recover. 24) Current artificial seed collection method I. The living body at the time of seed collection is very small and needs fine nutrition. II. In the current method, seedlings are collected by culturing about 5μ of plankton. III. Culture of microplankton is sensitive to the conditioned reaction, and cultivation of the desired quantity is a very difficult technique. IV, Plankton cultivation is very difficult and requires a specially trained technician. V, and a large number of chemicals and large equipment and labor costs. VI, the drawback of this method is that it has to be shipped in about 3mm. VII, raising more than 3mm is impossible under the current law. VIII, weaning meals are not prepared, and the number of juveniles attached to them is so large that it largely depends on the permissible limit of the bulk density of the seedling tub. IX, because artificial feeding is used, the water exchange is insufficient, and if the degree of water exchange is increased, the feed at an angle will be washed away. X Since the living body at the time of shipment is fine, the mortality during transportation is high. 25) Onshore Natural Seedling Method Using Artificial Water I. In this method, natural onshore seedling can be artificially harvested with no chemicals and no feed. II. Since this facility is at room temperature all year round, regardless of the seasons,
You can always harvest seeds as planned. III. Reproduction and restoration of the natural sea harvesting method. There is no need for IV, medicine, culture facility costs, special technicians, etc. V. The method of collecting seedlings using cedar branches and leaves was developed by Iku in July 1947. The method of collecting seedlings will be described below in detail. A. From about 30 days before the date and time when the seeds are to be collected, the temperature of the mother mussel culture tank is increased by about 1 ° C. per day, and gradually raised to about 33 ° C. B. After about 20 days, the ovaries are yellow and stick to the bread. C, prepare cedar branches and leaves. (Don't cut it into small branches.) D. Drain the mother mussel culture tub back from the drainage basin. E. About 70% of the nutrient water and about 30% of the drainage of the shellfish cultivation tub are sent to the seedling tub. F. With the zero return water machine, the flow rate of air water was slightly reduced,
(Approximately 30% less than normal aquaculture) Slow down the tide speed. G, the color of the air of the shellfish tub changes to yellow by ovulation. H, confirm ovulation, immediately cedar branches and leaves 30c below the surface of the seedling tub
(In this case, insert cedar leaves so that the bottom of the tub is not visible.) (Sperm and eggs are instinctively floating in search of dark places.) Is gradually returned to 23 ° C (about 1 ° C per day). On the 7th day, the attachment of juvenile shellfish to the underside of the dark cedar leaves can be visually confirmed. And water supply from the drainage basin is stopped. E, switch to water supply with total nutrient water. W, 0 Return amount Return the flow rate of the water machine to normal. Mosquitoes and the attached larvae crawl splendidly on the upper surface of the cedar leaves in search of light. (This is an instinctive behavior.) Yo, when the larvae grow to about 1 cm, collect them and cultivate them in a culture tub. (In this method, as in the natural sea, the colostrum meal [5μ
Degree) Weaning food [about 10μ] Juvenile shellfish food [20-30μ
), A large amount of useful plankton is generated in the mixture, so that the larvae grow and grow immediately in response to the larvae. I do.
