In April 2022, the prefectural university will open a new department, the Advanced Aquaculture Science Department, where you can learn practical theories for sustainably increasing the production of high-quality marine products and providing them safely and securely. The new department will start with 12 faculty members, strengthening the existing Department of Marine Bioresources related to aquaculture (fish diseases, biological production, fisheries economics), and the new fields of feed nutrition, breeding, and information science. .

Currently, we are aiming to determine the optimal feeding schedule for minimizing leftover food and training to the target size by AI analysis. In general, fish farms are raised based on a certain amount of feed (percentage to body weight, etc.). Therefore, if the total food intake fluctuates due to growth or death during the rearing period, it becomes difficult to set an appropriate feeding schedule. If we can control the actual amount of food consumed by considering the size and number of fish we keep, we can solve the problems mentioned above.

Therefore, as the first step, we have been developing a leftover food counting system that monitors the amount of food consumed during the breeding period using a land-based closed circulation tank. Although it is a simple system that combines an automatic feeder, a large funnel and an optical fiber sensor, it is possible to change the amount of leftover food in a day just by slightly changing the amount of reward when the feeder operates once. I understand. We are also trying to estimate the size and number of fish in a land-based tank using a fish finder. We are not even halfway there yet, but we would like to make efforts to develop a “feeding navigation” system that is useful for aquaculture sites. The Department of Advanced Aquaculture Science specializes in breeding technology based on genome science, smart aquaculture using AI and IoT technology, scientific aquaculture technology, land-based aquaculture technology, and environmentally friendly aquaculture farms and their surroundings. We have put together a curriculum that allows students to systematically study production techniques, as well as feed development for producing delicious fish demanded by the market. We hope that students will gain a scientific understanding of the current state and problems of aquaculture, and acquire the ability to put cutting-edge technologies into practice. In addition to developing the domestic aquaculture industry and creating local industries, we also aim to develop human resources who will play an active role in the field of aquaculture with international leadership.

The capacity of the new department is 30 people, and education will be carried out in small groups. In the first year, students mainly take general education courses at the Eiheiji Campus, where other faculties are located. increase. Katsumi Campus is a campus for advanced aquaculture science, and will be developed on the same premises as the University's Marine Bioresources Coastal Research Center and the Fukui Prefectural Fisheries Center. Obama Bay spreads right in front of you, and you can enjoy the beautiful scenery. In and around Obama Bay, not only marine fish farming but also non-feed farming of wakame seaweed, Pacific oysters, and pearls is practiced. Taking advantage of this location, after mastering the basics and theory of aquaculture technology at the Katsumi Campus, you can conduct applied experiments, as well as empirical training and exercises on the nearby sea surface. In addition, through the Fukui Fisheries Promotion Center, which was established on August 1, 2019, we have built a network with prefectures, municipalities, private companies, and research and development institutes, and are working with aquaculture groups and research in Fukui Prefecture. It is possible to smoothly promote cooperation with institutions in lectures, experiments, and practical training. In the new department, we have introduced a specially-appointed lecturer system, inviting producers, people active in community activities, and people from testing and research institutions as instructors to teach us practical initiatives. It is supposed to be Taking advantage of these advantages, we will conduct education and research with an emphasis on practical experiments and training in the field after acquiring the basic skills of applied aquaculture.

The other day, I attended an entrance examination briefing session held at a coeducational school in Fukui Prefecture. After the university-wide explanation, each department was supposed to give an explanation. More than 20 students participated in the explanation of Advanced Aquaculture, and all of them were boys. I strongly felt that there is a gender bias in the image of aquaculture. It is necessary for people to understand that aquaculture science is not only food production, but also interdisciplinary fields such as genome science, environmental science, and regional revitalization, and is directly connected to society. We hope that the new department will change the image of aquaculture, and play a role in motivating young people with new ideas and sensibilities to show interest in this field.

Three years ago, I made a presentation on the development status of glass eel production technology at this study group. This time, in response to a request to contribute to the newsletter, I would like to introduce the status of our efforts and future prospects.

At present, we have reached the technical stage where we can raise about 10,000 glass eels per year in breeding facilities at research institutes. On the other hand, the number of glass eels required for eel farms in Japan is approximately 100 million. Of course, it is not necessary to produce all of them at one place, but in order for glass eel production technology to be implemented in society, we believe that it is necessary to build a technology that can stably produce at least 100,000 eels per year. Also, according to our calculations, the current production cost for one glass eel is about 3,000 yen. The distribution price fluctuates greatly, but it is about 10 times the price. We believe that we have finally found the way to mass production and commercialization, and in order to realize this, it is essential to introduce various new technologies, including land-based aquaculture technology, which has been progressing in recent years.

The important technologies required for mass production and cost reduction of glass eels are as follows.
water purification. Since an excessive amount of slurry feed is put into the breeding tank as food, a large amount of seawater is poured over it to maintain the water quality in the tank. Water purification technology is important for reducing the cost of producing a large amount of heated seawater, reducing the environmental impact of wastewater, and increasing the degree of freedom in setting up seedling production facilities. We are also considering circulating breeding, but the hurdles to establish a completely closed circulating breeding system are high.

Promote growth. In captivity, it takes about 200 to 300 days from hatching to the start of metamorphosis into a glass eel. On the other hand, it is known that metamorphosis begins in about half the number of days in nature. The length of the breeding period directly affects the cost, and a shorter breeding period can be expected to improve the survival rate. In addition to improving feed and breeding methods, we are also working to introduce the latest breeding technology to create strains with a short larval period.

mass production system. Eel larvae cannot be reared on the scale of large concrete tanks like other fish species for which seedling production techniques have been established. Therefore, it is necessary to develop a system for mass production by installing many small-scale water tanks. Recently, I've seen articles about the development of large-scale land-based aquaculture facilities, but for glass eel production facilities as well, comprehensive development of systems such as water tanks, water quality monitoring, and automatic feeding is required assuming the scale of the production facilities. will become

In addition to these, we are working on multifaceted efforts to establish glass eel production technology, such as egg collection technology and disease control. The recently announced "Green Food System Strategy" aims to replace 100% artificial seedlings by 2050. Achieving this goal requires an all-Japan effort.

History and current state of complete aquaculture - Focusing on the efforts of Kindai Research Institute of Fisheries Science -
Full aquaculture is an aquaculture that repeats the process of retrieving artificial seedlings as parent fish, raising the eggs and hatched larvae, cultivating them based on the raised seedlings, and shipping them. As translated, the life history of farmed fish is "perfectly" cyclical under artificial conditions. The Fisheries Research Institute of Kinki University (Kindai Fisheries Research Institute) believed that the production technology of artificial seedlings was important for the stabilization of the aquaculture business, and since 1960, the Taiyo Fishery (at that time) was established on Mejima Island in the Nagasaki Prefecture Men and Women Archipelago. Attempted artificial insemination using mature yellowtail caught in Japan, and started research on production technology for artificial seedlings for aquaculture. At the same time, we started breeding parent fish using cultured yellowtail, and in 1967, we succeeded in retrieving eggs from the cultivated yellowtail parent fish by hormone treatment and artificial insemination, and in 1969, we succeeded in producing mojako from the cultivated yellowtail - complete aquaculture. was achieved in 2012. Beginning with flounder and parrotfish (1969), we have achieved complete farming of red sea bream (1971), striped jack (1983), stonefish (1991), and bluefin tuna in 2002. To date, we have cultivated more than 20 species of fish. achieved with

Complete aquaculture achieves planned and efficient aquaculture because it does not rely on natural seedlings. Furthermore, as an application of complete aquaculture technology, a group of individuals with excellent traits (here, growth traits) is selected from the produced seedlings, and by repeating complete aquaculture with the selected group as the parent, the superior traits are fixed. You can go. Kinda University Research Institute has succeeded in selective breeding of red sea bream, which it has been working on since the latter half of the 1960s. With artificial seedlings from natural parents, it takes about 3 years to grow to 1 kg in weight, but Kindai red sea bream grows in about 1.5 years, which is half the time. This achievement had a great impact on the red sea bream farming industry. Domestic aquaculture production of red sea bream is second only to yellowtail. Even now, it is the main fish species in Kindai's seed business (seedling sales). Kindai red sea bream is also famous as a successful example of breeding for marine fish.

In recent years, efforts toward the sustainable use of resources and the fisheries eco-label certification system that guarantees such efforts have expanded worldwide. The 14th goal of the SDGs (Sustainable Development Goals), “Let’s protect the abundance of the sea,” is closely related to the aquaculture industry. Among them, there are mainly problems of seedlings and feed for aquaculture that does not depend on natural resources, and complete aquaculture technology is essential to solve these problems. It is hoped that full aquaculture and the utilization of certification systems such as SCSA (Seedling Certification Council for Sustainable Aquaculture) certification that guarantees full aquaculture will become an appealing force for expanding domestic production and exports. increase.

About 10 years ago, I pondered the usefulness of land-based aquaculture and wondered what the basic requirements were for efficiency. If you dare to reprint it here

1) How to select target organisms
2) How to design the system
3) How to secure water for use
4) Where to get seeds
5) Which feed is better?
6) How to prevent disease and wastage
7) where, when and through where to sell the product
8) Where do you go for help when you have a problem?
9) How to advertise the goodness of the product
10) What are the relevant legislations?

In other words, I intended to point out that the point is to accumulate basic know-how such as (1) improving the technology that allows breeding, and (2) creating demand and establishing supply technology. Under the leadership of Professor Hirono of the University of Marine Science and Technology, this "Land Aquaculture Study Group" was supported by the dedicated support of the secretaries who had already been working hard at the site, and Exhibition Technology Co., Ltd., etc. I have heard that the association has grown to 800 members, and I am very pleased to publish the information media. It is expected that the number of people in the field who agree with the purpose of the association will increase in the future, but if possible, we should (1) diversify the target species and (2) incorporate "breeding (genetic manipulation)" into the technical aspect. I would like to recommend that you incorporate these as issues to be addressed. As an example, I would like to mention a small Nishikigoi that can be kept in a corner of the living room. The world is the space age! How about a pet fish breeding system that can be placed on the windowsill looking at the earth? Of course, water-saving and non-feeding types will be required, so the circle of infrastructure technology will also expand. However, since it is nothing more than the nonsense of an old man living in isolation, there may be little need to raise a meeting and work on it. Looking forward to the further development of the Society and to meet the demand.

Recently, we often see news about the development of large-scale land-based farming of salmon and trout by foreign capital in Japan. It is carried out by law, and land-based aquaculture is limited to a small number of fish species such as flounder. The main reason for this is that both the initial cost and the running cost of land-based aquaculture are higher than net-ikesu aquaculture. In other words, the key to the success of land-based aquaculture is how to raise fish with a high unit price and how to reduce the cost. In the case of net fish farming, feed costs account for the highest percentage of the production cost, so it is important to keep the meat gain factor low. The fat gain factor of salmon and trout in seawater farming is low, around 1.2 for Atlantic salmon and around 1.5 for coho salmon farming in Japan, which is about half that of yellowtail and red sea bream farming, which have a fat gain factor of around 3. One of the major factors is that the large-scale land-based salmon and trout farming business mentioned at the beginning was planned for fish species with low feed costs.
　
The Fisheries Research Institute of Kinki University is also working on cultivating cherry salmon as land-based salmon trout farming at the Toyama Experiment Station. Toyama Prefecture is famous for trout sushi. In the past, trout sushi was made using cherry salmon, but now almost no cherry salmon are caught, so imported farmed salmon trout are used. At the Toyama Proving Ground, water is taken from a depth of 100 m, and seawater below 20°C can be used even in summer. Taking advantage of this characteristic, we are proceeding with land-based aquaculture research on cherry salmon, aiming to increase the size of the salmon through full-scale aquaculture and selective breeding within Toyama Prefecture. Fish weighing up to 2.5 kg, which can be used for trout sushi, can now be farmed. Furthermore, we are also working on farming all-female triploid cherry salmon with the aim of increasing the size and shipping year-round.

The Kinki University Fisheries Research Institute is focusing on conger myriaster as a land-based aquaculture fish other than salmon and trout. According to the Ministry of Agriculture, Forestry and Fisheries' fisheries and aquaculture production statistics, the catch (conger eels) fell to about one-fourth nationwide from 1995, when statistics were first collected, to 2019. The unit price tends to rise as the catch decreases. When we tried breeding after juvenile conger eels, we found that food consumption decreased significantly at high water temperatures above 25°C, and that they began to die at temperatures above 27°C. It was found that the juvenile fish grew to the shipping size of 200 g in about half a year. In order to reduce running costs in land-based aquaculture, it is important to select fish species with a short farming period, and I believe that conger eels can be expected as a target species for land-based aquaculture.
　
Reducing production costs is a major issue in land-based aquaculture, but I am conducting research with the hope that this issue can be overcome through the selection of appropriate fish species and the introduction of selective breeding that applies new technology.

The technical bottleneck in completely closed circulation land-based aquaculture was in the process of removing nitric acid and water-soluble organic matter accumulated in the breeding water. By developing an aerobic denitrification device and introducing a shearing foam separator, we were able to solve these problems and complete a high-performance completely closed circulation land-based aquaculture system. As a result, the replacement of water, which was essential for land-based aquaculture, is no longer necessary, and land-based aquaculture of fish and shellfish can be safely and securely carried out with ease anywhere without worrying about fishing rights or environmental pollution associated with water intake and drainage. I was. Under a completely closed circulating aquaculture system, fish health is improved, growth and feed efficiency are improved, mortality rate is reduced, and invertebrates such as abalone and sea urchin can be kept for a long time without water exchange, which was not possible until now. Now possible. In addition, there is no unpleasant smell of geosmin in the breeding water even after long-term breeding, and there is no smell of geosmin in the flesh of fish and shellfish. It is being used in various fields, but it was an unexpected pleasure to be able to propose another collaboration between fisheries and welfare using this system (Suifuku collaboration).

Since the enactment of the Act on Comprehensive Support for Persons with Disabilities, employment of persons with disabilities has progressed in various fields of society. In the agriculture, forestry and fisheries industry, collaboration with welfare is active, especially in the field of agriculture, and it can be seen from the fact that many activities are hits when searching on the Internet. On the other hand, Mizufuku cooperation hits only a few activities. The reason for such a large difference is that fishing is dangerous and heavy work, the work place is in a remote area, and it is not possible to earn money. However, aquaculture using a completely closed circulation land-based aquaculture system has the advantages of being free from danger, easy to work, and being able to be carried out in cities. I was able to open it. An example of this is the activities to support people with disabilities by NPO Donguri no Kai (Tsu City, Representative: Fumi Ikeda), which began last year with the support of the prefecture and the local community. At the beginning of learning the technique, filefish, which grows quickly and is easy to keep, was farmed on land without changing the water, but in about four months, they were big enough to be tasted and delicious. has increased further. I hope that this kind of Mizufuku collaboration will spread more and more, leading to regional revitalization and the revitalization of the fishery. Also, seeing the children who attend the Donguri no Kai delight in watching the fish grow and swim, we may be able to contribute to school education, such as environmental education through the breeding of seafood and fireflies. I think.

How to adapt to Wiz Corona? With the start of vaccination against the new coronavirus infection, the "new normal" has entered a more practical phase, and further changes are required in our daily lives. On the other hand, corona or not, the problem of global population growth and food security has not changed. Rather, the importance of domestic production has been reassessed as a result of restrictions on transportation due to measures against corona infection, and I feel that the role of the aquaculture industry is increasing day by day. Therefore, this time, I would like to introduce the trends in the aquaculture industry in recent years.

"Aquaculture Business", which has been in business for 58 years, has 13 monthly magazines and 1 additional issue, providing the latest information. underwater drone” and “AI/IoT”. As you can see, only the first one is a new fish species, the rest are all new technology. These fields are also called “smart aquaculture,” and new entrants from various industries such as major trading companies and venture companies are increasing.

One of the key words, “terrestrial aquaculture,” is currently said to be in the third boom, and development competition is taking place in countries around the world. In the October 2013 issue of our magazine, we carried out a special feature titled "The Road to Commercialization of Closed Recirculating Land-Based Aquaculture", and then started a serial project with the same title. We continue to hold special feature projects every year, and in April 2017, we published a book titled "Circulating land-based aquaculture: the latest technology and industrialization seen in case examples <domestic and overseas> by breeding stage". From 2018 onwards, we will continue special projects, and from August 2019, we will start a new bimonthly series, “The Road to Industrialization of New Closed Recirculating Land-based Aquaculture”. It has been published up to the present day. We are preparing a special feature for this year as well, so please look forward to it.

The general image of drones has been that they fly in the sky, but another keyword that is expected to be the next frontier is "underwater drones." Industry groups have predicted that the Japanese underwater drone market will expand from 2 billion yen in 2020 to 3.9 billion yen in 2023. In addition to being used for infrastructure development, ship bottom surveys, and seabed surveys, its applications are expanding to include growth surveys for farmed fish and shellfish, inspection of fishing gear, and collection of dead fish in the aquaculture industry. This technology is attracting attention not only from a cost perspective but also from a safety perspective, as it can support divers in these tasks that were essential to them. In the January 2020 issue, we planned a special feature "Introduction to Underwater Drones for Aquaculture" as an introductory edition, and in the May issue of this year, we plan to feature "Drones for Aquaculture in Japan and the World (Tentative)". We have included the latest information from around the world, so please take a look.

Finally, the 18th Seafood Show Osaka, which had been postponed due to the corona crisis, will be held from March 17th to 18th. The "Land Aquaculture Seminar" will be held on the first day, and the "Aquaponics Seminar" will be held on the second day. When the future is uncertain, we need a guideline. In this study group, we will continue to provide a place where people and companies interested in land-based aquaculture can interact and work towards the development of the industry.

From last year to this year, I was reminded once again how important health management is due to the influence of corona. Health management is also very important in the aquaculture business. In this article, we will use shrimp farming as an example to demonstrate how to ensure proper health management.

Shrimp diseases and production problems are different at each stage of development. Shrimp mortality, slow growth rates, and low yields due to high feed conversion rates take an economic toll on shrimp production facilities. Diseases such as taura syndrome virus (TSV), white spot disease (WSSV), vibriosis, and acute hepatopancreatic necrosis (AHPND) cause substantial losses in many aquaculture areas worldwide.

Effective control measures to prevent disease outbreaks and spreads are associated with appropriate production control systems. In poorly managed environments, growth and survival rates decline. This is true whether aquaculture takes place in large saltwater ponds or in intensive land-based aquaculture facilities in freshwater canals. Moving to a high density production management environment will increase stress factors. Good management practices need to be developed and implemented to ensure that the stress on the shrimp remains within certain limits. Seasonal changes are also known to affect shrimp health, with disease problems often occurring in hot summer weather.

Maintaining biosecurity and preventing disease outbreaks is the goal of all farm managers. Biosecurity is defined as preventing disease, preventing the transmission and spread of that disease, and protecting shrimp from other health problems. The best way to prevent the disease in its early stages is to purchase juvenile shrimp from SPF facilities (Specific Pathogen Free Facilities) or from a high health shrimp supplier. When bringing shrimp purchased from a new supplier into the facility, quarantine the shrimp at the time of purchase or at the farm, and check the health certificate issued by the partner country's government.

In addition, when employees handle shrimp that have arrived from other places, please wash and disinfect their hands before starting work. Even doing something as simple as moving a box of frozen shrimp from the grocery store can result in bringing frozen bacteria to your farm. Movement of people can also carry pathogens from one farm to another. After visiting other farms and before working at your own farm, please disinfect your hands and feet, take a shower, and change your clothes and shoes.

These principles are three. "Cannot enter", "Cannot wear", "Cannot take out".
"Do not enter" is a precaution to prevent pathogens from entering from the outside, such as introducing SPF young shrimp and disinfecting when people come and go. "Non-wearing" means to properly control the breeding environment and reduce the occurrence of pathogenic bacteria there as much as possible. "Do not put out" means that the facility that has finished training must be disinfected once and do not release dangerous things outside the facility. If you can follow these basics, you can safely produce shrimp. I think land-based aquaculture technology will continue to develop and new technologies will be born, but I don't think the principles of breeding will change that much. In the future, I would like to keep in mind the careful upbringing.

Happy New Year to all the members of the "Land Aquaculture Study Group".

Since the beginning of last year, the new coronavirus infection has been raging around the world, and the way we work and the form of food have changed significantly. We are forced to adapt to various changes in our lives that are somewhat inconvenient. Many occupations have been affected. I just pray for the end of viral infections due to the advancement of medical care such as vaccine development in the future. I also think that attention will be paid to how society will revive after the end of the world. It is conceivable that new methods and technologies born out of this uneasy lifestyle will be used in various places even after the end of viral infections, creating diversity.

Diversity is also required in the marine industry, and the production and supply of safe marine products and their increase are always desired. Among them, the development of aquaculture is also expected, and it can be said that land-based aquaculture plays a part of it. Land-based aquaculture incurs costs for facility construction and energy, but it is possible to produce in a stable environment, and it is relatively easy for new entrants to enter the market, as well as the use of surplus energy and links with related industries such as cooperation with tourism. It has the advantage of being able to directly generate Based on various technologies and ideas, a wide variety of rearing systems have been developed, ranging from very small ones with a few tons of water to large facilities with tens of thousands of tons of water, and optimized production forms according to conditions such as climate, water supply, and location. has been realized.

Land-based aquaculture is the form of aquaculture that can realize the widest variety of production methods among aquaculture. In recent years, aquaponics, which combines fish farming and hydroponics, has also been attracting attention. Aquaponics can produce organic vegetables by suppressing the discharge of water pollutants from the aquaculture system by performing hydroponics using substances discharged from aquaculture as fertilizer. Recently, some companies that specialize in aquaponics have started commercial production in Japan as well. In addition, small-scale systems are used for education at fisheries and marine high schools, and systems that combine ornamental fish and foliage plants are being sold in the world of hobbies. At the land-based aquaculture study group, we launched an aquaponics subcommittee as a sub-organization for the purpose of exchanges between industry, academia, and government centered on aquaponics, and held a seminar at the "Japan International Seafood Show" at the end of September last year. I was. We plan to hold seminars on a regular basis in the future.

Finally, food production, distribution and sales in the future will be affected by the global spread of COVID-19, and it is expected that “diversification and selection” will progress based on needs. The land-based aquaculture study group will continue to provide information related to land-based aquaculture and related fisheries. We will continue to plan seminars and lectures based on the needs of our members. It is expected that the tough situation will continue for a while, but we will continue our activities from what we can do.

Thank you for your continued support in the year.

At the "Land Aquaculture Study Group", information will be distributed from the study group secretaries and lecturers to the members for the purpose of interacting with the members. As the first step, I would like to introduce the “Land Aquaculture Study Group” again.

The predecessor of the "Land Aquaculture Study Group" was a group that held seminars on aquaculture mainly at the "Japan International Seafood Show" led by Professor Emeritus Fumio Takashima of Tokyo University of Marine Science and Technology. When I started the seminars, there were only a few people in the audience, but since I started holding seminars on the theme of land-based aquaculture, the number of attendees has increased year by year, so I decided to hold a land-based aquaculture study group. ”, and the purpose of the “Land-based Aquaculture Study Group” is to “conduct various studies to spread the land-based aquaculture business as one of the ways to revitalize the aquaculture industry in Japan. At the end of March 2013, the first "Land Aquaculture Study Group" was held at the Tokyo University of Marine Science and Technology Shinagawa Campus in conjunction with the Spring Meeting of the Japanese Society of Fisheries Science.

There were more than 100 participants in the 1st "Land Aquaculture Study Group". The participants are not only companies related to the so-called fishery industry, but also many participants from fields unrelated to the fishery industry so far, and we would like to recognize that there are many people who are interested in land-based aquaculture. It was a meeting to be done. Since then, we have held four seminars on land-based aquaculture study sessions every year. In 2020, due to the influence of the new corona, the "Land Aquaculture Study Group" seminar was held twice, but so far we have held 29 seminars. The number of members has increased with each seminar, and as of November 2020, the number of members exceeds 700.

In the future, the “Land Aquaculture Study Group” seminar will be held in midwinter at the “Seafood Show” in Osaka, and in early summer at the “Agricultural and Fishery Industry Support Technology Exhibition” in Okinawa (2020 will be postponed to March 2021 due to the influence of the new corona). The Japan International Seafood Show will be held in Tokyo in midsummer, and will be held at Tokyo University of Marine Science and Technology in late autumn. In addition, a seminar specializing in aquaponics combining land-based aquaculture and vegetable factories was started at this year's Japan International Seafood Show led by Professor Masato Endo of Tokyo University of Marine Science and Technology.

A get-together is also held when holding a seminar on land-based aquaculture at Tokyo University of Marine Science and Technology. We would like to continue to provide a place where people and companies interested in land-based aquaculture can interact. We hope that industries related to land-based aquaculture will continue to develop.

Lastly, although it may not have much to do with land-based aquaculture, I would like to introduce that Japanese universities are nurturing many excellent international students. In 2008, the Japanese government launched a plan for 300,000 international students, and by 2018 the target of 300,000 was achieved, including those enrolled in vocational schools. Universities are also educating international students and producing excellent researchers who are pro-Japanese. Most of these international students have returned to their home countries and are active in various fields in industry, government, and academia. Unfortunately, however, many people in the private sector do not seem to know that there are many excellent researchers and business people raised in Japan, mainly in Southeast Asia. If you are thinking about doing business overseas (especially in Southeast Asia), relying on a former international student who obtained a degree from a Japanese university may help you go abroad with peace of mind.

It's not easy to go abroad if the new corona infection doesn't subside, but I can only pray that the new corona infection will be contained soon, or a highly safe and effective vaccine will be available.

Lastly, although it may not have much to do with land-based aquaculture, I would like to introduce that Japanese universities are nurturing many excellent international students. In 2008, the Japanese government launched a plan for 300,000 international students, and by 2018 the target of 300,000 was achieved, including those enrolled in vocational schools. Universities are also educating international students and producing excellent researchers who are pro-Japanese. Most of these international students have returned to their home countries and are active in various fields in industry, government, and academia. Unfortunately, however, many people in the private sector do not seem to know that there are many excellent researchers and business people raised in Japan, mainly in Southeast Asia. If you are thinking about doing business overseas (especially in Southeast Asia), relying on a former international student who obtained a degree from a Japanese university may help you go abroad with peace of mind.

It's not easy to go abroad if the new corona infection doesn't subside, but I can only pray that the new corona infection will be contained soon, or a highly safe and effective vaccine will be available.

"Land aquaculture study group" bulletin distribution begins

At the "Land Aquaculture Study Group", information will be distributed from the study group secretaries and lecturers to the members for the purpose of interacting with the members. As the first step, I would like to introduce the “Land Aquaculture Study Group” again.

The predecessor of the "Land Aquaculture Study Group" was a group that held seminars on aquaculture mainly at the "Japan International Seafood Show" led by Professor Emeritus Fumio Takashima of Tokyo University of Marine Science and Technology. When I started the seminars, there were only a few people in the audience, but since I started holding seminars on the theme of land-based aquaculture, the number of attendees has increased year by year, so I decided to hold a land-based aquaculture study group. ”, and the purpose of the “Land-based Aquaculture Study Group” is to “conduct various studies to spread the land-based aquaculture business as one of the ways to revitalize the aquaculture industry in Japan. At the end of March 2013, the first "Land Aquaculture Study Group" was held at the Tokyo University of Marine Science and Technology Shinagawa Campus in conjunction with the Spring Meeting of the Japanese Society of Fisheries Science.

There were more than 100 participants in the 1st "Land Aquaculture Study Group". The participants are not only companies related to the so-called fishery industry, but also many participants from fields unrelated to the fishery industry so far, and we would like to recognize that there are many people who are interested in land-based aquaculture. It was a meeting to be done. Since then, we have held four seminars on land-based aquaculture study sessions every year. In 2020, due to the influence of the new corona, the "Land Aquaculture Study Group" seminar was held twice, but so far we have held 29 seminars. The number of members has increased with each seminar, and as of November 2020, the number of members exceeds 700.

In the future, the “Land Aquaculture Study Group” seminar will be held in midwinter at the “Seafood Show” in Osaka, and in early summer at the “Agricultural and Fishery Industry Support Technology Exhibition” in Okinawa (2020 will be postponed to March 2021 due to the influence of the new corona). The Japan International Seafood Show will be held in Tokyo in midsummer, and will be held at Tokyo University of Marine Science and Technology in late autumn. In addition, a seminar specializing in aquaponics combining land-based aquaculture and vegetable factories was started at this year's Japan International Seafood Show led by Professor Masato Endo of Tokyo University of Marine Science and Technology.

A get-together is also held when holding a seminar on land-based aquaculture at Tokyo University of Marine Science and Technology. We would like to continue to provide a place where people and companies interested in land-based aquaculture can interact. We hope that industries related to land-based aquaculture will continue to develop.

Lastly, although it may not have much to do with land-based aquaculture, I would like to introduce that Japanese universities are nurturing many excellent international students. In 2008, the Japanese government launched a plan for 300,000 international students, and by 2018 the target of 300,000 was achieved, including those enrolled in vocational schools.
