Understanding Aquamimicry Better Series 1 - 6th Republic of Vibrio

The Egyptian team, which returned from a 10-day indoor shrimp farming training session on the 10th of last week (Oct. 2016), consisted of one vegetarian and two halal food eaters.

Even before I left Egypt, I asked for halal and vegetarian food, so I gladly answered, "I would do so." When I searched the Internet, vegetarian restaurants and halal restaurants were not quite common in Korea.

Last summer, a Saudi Arabian friend visited Halal Food at the top of Hannam-dong, and I thought it was too late to remember that there was no parking lot, and I couldn't communicate with the restaurant owner in Korean, but it was too late.

Because our farm is located at the northern end of the west coast, which takes 1 to 2 hours from Seoul, there are few restaurants because it is usually not crowded.

As I learned through this opportunity, there are six vegetarian classes.

From full vegetarian to fish-eating class, to milk-eating class, etc.

It is said that the name is different depending on the class.

• Vegan: Only 10% of vegetarians are vegans who don't eat meat at all. They get all the nutrients from fruits and vegetables, bread, grains, and nuts (peanuts, beans, etc.). They are those who thoroughly study and practice plant nutritional ingredients that can replace them because they cannot consume any round nutrients.
• Lacto-ovo Vegetarian: In fact, it's safe to say that this is the case for almost all vegetarians. They don't allow meat and fish, but they supplement protein with milk and eggs. These include those who are mainly vegetarians for their health rather than their beliefs.
• Lacto Vegetarian: A slightly more stringent category than Lacto Ovo vegetarians. They eat milk, but they don't eat eggs that can be turned into life. Even if you eat whipped cream cake, you eat the cream part made of milk, but you don't eat the castella with eggs.
• Pesco Vegan and Semi Vegan: Pesco Vegan means people who eat eggs and milk as well as fish. Usually, it can be seen as a step chosen by those who enter a vegetarian diet. Semi-vegetarians even eat chicken.
• Fruitarian: Even if you eat vegetables, some people refrain from eating the roots or leaves that produce life and take only fruits. These people are only 10% of all vegetarians. Usually, most people are from a religious belief or biological standpoint.

By the way, have you heard that vannamei, the white-legged shrimp that we raise, is also Vegan?

We're entering the Sixth Republic of Vibrio.

Do you remember the doubling time?

The time it takes for one germ to become two and two to become four.

In terms of human beings, the average time it takes for a generation to have a child is called generation time, and bacteria also refer to the time it takes for a child to be made.

I told you then that there was a bacterium that could rival Vibrio. Do you remember? We use the same principles as the results of the experiments above.

Vibrio's doubling time is about 20 minutes, lactobacillus is about 20 minutes, and Bacillus is about 20 minutes. So it's also a way to control pathogenic vibrio by inoculating it with bacteria that we call probiotics that can be used for various purposes.

It induces bacteria to compete against each other in laboratories and fish farms.

At the end of the Vibrio Republic, we'll have a chance to say this again when you describe how to fight Vibrio.

But the diseases that these vibrio causes are so incredibly huge and so vicious that it drives not only the aquaculture people around the world but also all the research institutes, schools, and governments involved.

First of all, the past white spot virus (although it still occurs) has been caused by early death syndrome, or EMS, or vibrio, which has frightened fish farms around the world since 2009 in China.

Until the '80s, Taiwan was the country that dominated shrimp farming technology around the world.

The ease of management of farms and excessive greed caused environmental pollution and disease spread disaster, and eventually handed over shrimp power to Thailand, and Taiwan became a ruin of shrimp farming as if a tsunami had swept through it.

Now Thailand, which has enjoyed 20 years of glory, is going through the same process. Thailand's eastern shrimp farm, which uses the water of influent and effluent as culture source water in every farm, is now suffering from measles, and production has declined by one-third over the years. The area of the fish farm, which used to be over 44.000 hectares, is now 5,000 hectares closed and the shrimp farm, which is still in place, is moving to the east coast of the south.

This is because shrimp is no longer available near Bangkok due to marine pollution. In a few years, more than 5,000 hectares of fish farms will be reduced.

And this kind of energy is moving to Indonesia, India, Central America, South America, etc.

However, the problem is that Thailand has been alone so far, but now the number of countries that can replace Thailand's losses is rapidly increasing.

Vietnam, Indonesia, India, Myanmar, Bangladesh, Ecuador, Mexico, Peru, Brazil, Saudi Arabia, Iran...It's increasing the shrimp farming industry a lot.

And the day before yesterday, Egypt is about to start a new vannamei species. So far, they are raising Fenneropenaeus indicus, India white shrimp.

In 2015, I read an article about duty-free shrimp imports from Vietnam.

However, not all shrimp are produced in Vietnam.

A significant amount of shrimp exported from Thailand or Vietnam is actually imported from other countries.

It is imported from Indonesia, India, Ecuador, Columbia, etc., processed and exported from Thailand and Vietnam. Of course, it is also exported to Korea.

Looking at it that way, it is no different from exporting shrimp from all over the world to Korea.

It is time to change the paradigm of shrimp farming.

With more advanced technology and healthier shrimp, high productivity will be required to survive the competition.

It seems that what needs to be done now and, in the future, has already been decided.

There are about 12 strains of Vibrio bastards, which are known to cause human disease, most of them food poisoning, caused by enteritis and septicemia.

The sea is home to Vibrio bastards, so Vibrio infection is naturally transmitted from seafood to humans.

When we raise shrimp, we have to fight these Vibrio bastards to keep shrimp well, but there is a possibility of infecting people, which is why we need to be careful about post-harvest treatment.

In Korea, most of the shrimp are sold live and fresh, so they don't seem to pay much attention to it.

However, if you look at the contents so far, since they are opportunists, there is still room for lowering the product quality at any time during the post-harvest movement process and the subsequent distribution process. This is because they can cause diseases such as food poisoning in humans and lower product quality.

Therefore, it is necessary to thoroughly sterilize and manage not only the health of the pond or tank just before harvest, but also the sanitary conditions of harvesters, mobile vehicles, and various equipment used for transportation. You have to pay attention.

Toxins originally produced by bacteria are not intended to harm other living things, but contain the nutrients of bacteria in the first place. However, it is a deadly poison to other animals and bacteria.

The following is the Vibrio bacteria strains that cause disease in humans among 100 species of marine Vibrio bacteria.

Well, there is no reason or need to know this, but I still need to know a bit about the bacteria that are suffering from measles worldwide, so I did some research to study.

1. Vibrio cholerae,
2. Vibrio parahaemolyticus,
3. Vibrio vulnificus,
4. Vibrio streptococcus
5. Vibrio alginolyticus,
6. Vibrio fluvialis,
7. Vibrio metschnikovii,
8. Vibrio damsela,
9. Vibrio hollisae,
10. Vibrio mimicus,
11. Vibrio furnissii,
12. Vibrio cincinnatiensis,
13. Vibrio carchariae

There is a copy of this in our country's advertising copy.

A moment's choice determines the coming 10 years.

How you start shrimp farming is the key to success or failure.

If you stick to the basics initially, it will be convenient later.

Thorough preparation will make the treatment easier or simpler later on.

More or less CAPEX or OPEX is not a good or bad criterion for culture methods.
