What is the oyster countermeasures that occur in the Umi Forest Suitoshi Stadium Course Column Tokyo Olympics?/ What happened to that problem No.1 --Nikkan Olympic One -Oggi OH! Olympic

Can't you eat oysters at the Olympics (Olympics) venue?The Sea Morizui Stadium (Koto -ku) is a newly established boat of the Tokyo Olympics and a canoe venue.It was about five months ago that a large amount of oyster had occurred on the wavy device installed on the course.At the venue, a battle with a boat Olympic ticket starts on the 6th.What happened to oyster measures?Can't use oysters as ingredients?I asked Tokyo and oyster experts.

Oysters are also called "sea milk" because they contain a rich nutrient with milky white body.It is a high -quality ingredient with the scent of the shore, and is one of the charms of the unique texture.

Such oysters have become a hindrance in the Olympics.The place to discover the problem is the Sea Morizui Stadium, which was newly established as the Tokyo Olympics venue.A large amount of oyster adheres to the wavy device installed on the water surface.The weight sinks the device and hinders the function to prevent waves.

According to the Tokyo Olympic and Paralympic Preparatory Bureau, the presence of oysters was found in August 2009 after being pointed out during the international competition for boat competitions.After that, the situation became more serious as the oysters were "seasonal" in winter.Tokyo temporarily removed a total of about 14 tons of oysters from December 2019 to March 2019.The cost was about 140 million yen.

Why did a large amount of oysters occur?The surveyed capital presumed that the water quality containing many plant plankton and the salt concentration in which seawater and freshwater are mixed is suitable for the growth of oysters.As of January this year, the person in charge acknowledged the unexpected situation, but said, "I am not holding my head. We are considering future measures while listening to the opinions of experts."

About six months have passed, and has the solution prospect?When I hit the person in charge again, "There is no major progress at this time ...".Nevertheless, the wavy device, such as the north side of the course, where oysters were noticeable, seemed to have been fried on land for a while, and there was no spread.

At the venue, the Tokyo Olympics Asia and Oceania Continental Qualifiers will begin on the 6th just one day late after repartitions due to strong winds.As of late April, when the wavy device had been re -installed, the person in charge asserted that "it has no effect on the competition."He said that he would not be able to conclude quickly to solve oyster problems, saying, "The most important thing is that this stadium will be used for a long time after the Tokyo Olympics. The most efficient and effective effects are taken into account.I'm looking for a method. "

A large amount of magaki is used, and is used for raw food, pots and fries.The capital was incinerated as a waste, but can't it be used as an ingredient?Daisuke Mimura (38) of the Japan Oyster Association Oyster's Japan (38) pointed out that there is a great deal of concern about hygiene in Tokyo Bay, where sewage flows."If heated, it is unlikely that you will become food poisoning immediately," he said, "If you talk about oysters that grew up in an environment where you do not know what is included, you may die."

Almost all of the magaki distributed in Japan is aquaculture and natural things are close to zero.It is common to say that there is a difference in taste and quality as well as safety.Wouldn't it be a profit if the one was sold as a "Tokyo Olympics oyster"?Mimura's representative, "I can't sell it first," smiled.The reporter's shallow ideas disappeared with sea algae.[Mikihiro Okuoka]

◆ Magaki is a typical type of oyster.The spawning period is June -September, and the season is winter.The meat quality is thick and has a rich taste.Most of the market on the market are cultured and produced.The seasonal season in the summer is Iwagaki, the grain is large, the body is thick and juicy.This is mainly natural catch, but it also distributes aquaculture and production.There are other suminoe gaki, glutinous kids, etc.

◆ As a competition for the Sea of the Morizui Stadium Boat and Canoe Sprint, a waterway in the coastal area of Tokyo was developed, and a completion ceremony was held in June 2009.During the review of construction maintenance costs at each Olympics, it was reduced from about 49.1 billion yen to about 30.8 billion yen.Most of the temporary viewing seats were omitted.The annual deficit estimation of about 160 million yen is about 160 million yen, depending on the control cost of the sluice gate.The characteristic of the course is that there are many people who say that it is not uncommon for strong winds to blow, and the waves are likely to increase.
