Kinki University successfully completes eel farming

Kinki University has succeeded in completely cultivating edible eel. Previously, I was surprised to hear that eels had been successfully hatched artificially, but this time it will be completely farmed. The ecology of eels is not well known, and it was thought that eel fry hatched in the Philippines or near China, grew up, and circulated throughout the Japanese archipelago, but eels are now being farmed within Japan, including these areas.
Originally, eel was a delicate species that reproduced through wide-area circulation, and was rare and expensive, but due to the cost of aquaculture, it may soon become a food that can be easily eaten. What is noteworthy is the eel protein. Eel has more protein per １００g than beef.

The Japanese archipelago is poor in protein sources.

Originally, there were no large animals living in Japan, so people ingested protein from tofu, miso, and fish. Whaling was largely a cultural aspect and was a source of food for large animals and high protein content. If it were possible to farm eel in large quantities, it would be more efficient than other edible meats, and the result would be omega-３ fat, which is good for the body instead of animal fat.
Japan's food self-sufficiency rate is announced to be ６６% on a monetary basis, but the low level of ３８% on a calorie basis is largely due to protein deficiency. If edible eel were easily available on the table, the calorie self-sufficiency rate would rise dramatically.

World's largest rare earth mining

Recently, it was announced that rare earth mining will begin in ２０２４ in the deep sea of Minamitorishima, Japan's Ogasawara Islands. The amount of rare earths buried in this sea area is said to be the largest in the world, and is said to be enough to meet the entire world's demand for several hundred years. The underground oil reserves of the Ibaraki Prefecture Goura coast are estimated to be one of the largest in the world, based on the amount and area of gas generated on the seabed surface.

The only one in the world? Japan eats raw eggs. Why are raw eggs safe in Japan? Egg rice is a soul food in Japan. Japan seems to be the only country in the world that eats raw eggs. Japan is known as a country where tap water is drinkable, but you might think it's a similar story, but it's not. In Japan, tap water is drinkable because it is soft and sanitary water is thoroughly controlled, and eggs are only born from chickens, so there is no difference in countries around the world. Even if you explain it as a food culture, eggs are probably eaten all over the world, so why did Japan come to eat eggs raw? You might think it's a matter of Japanese tastes, but foreigners say that sukiyaki is delicious, and even simple rice with egg is delicious. Could it be that only Japanese people noticed the taste of raw eggs? If you ask foreigners, they will tell you that raw eggs are dangerous. Then, I wondered why Japanese eggs were so safe, and when I looked into it, I found out that Salmonella bacteria is contained in the parent hens' feces and urine and seems to penetrate through the egg shells. Alternatively, if the parent chicken is infected with Salmonella, eggs infected with Salmonella will be born. Current Japanese poultry farms take thorough measures to prevent Salmonella, which is why they can even be eaten as raw eggs. Then, when did Japan start eating raw eggs? When I researched it, I found that before the Edo period, food derived from animals was avoided due to the influence of Buddhism, and there seems to be a mention of raw eggs in the Edo period. Later, there was a mention of tamago kakigohan (egg-dried rice) in the Meiji period, and it is said that Ogai Mori also liked eating it. When I researched Salmonella, I discovered that it was named after Daniel Salmon, a bacteriologist who discovered the type strain of the Salmonella genus, Hog cholera, in the United States in 1885. It became. In the Edo period, there would have been no recognition of Salmonella. In summary, Japanese people did not have any biological knowledge about Salmonella, but they did know that if parent chickens were kept in an unsanitary environment, the baby eggs would have fatal problems if eaten by humans. On the other hand, they knew that if they thoroughly managed and cleaned the chickens, this problem would not occur.

Possibility of world's largest oil field

Japan has not made any progress in marine resource development. Despite the fact that there was a lack of resources as a reflection of the defeat in the war, Japan continued to engage in resource diplomacy by relying on foreign sources, and these became a conduit to oil-producing and other resource-rich countries. However, when the world becomes this unstable, it is impossible to say such things.

Japan has the ６th largest area in the world, including the EEZ.
