"To go too far is not enough, to go too far without thinking." - "The Analects of Confucius"

There is a kind of shrimp called Luo Shi shrimp, which is a large shrimp living in fresh water. Economic shrimp, known as the king of freshwater shrimps. Romanian shrimps are cultivated in many provinces in southern China and are a favorite delicacy of our people. However, this kind of prawns is overrun in Vietnam. The Vietnamese are still unable to solve the piles of Romanian shrimps by opening the Mekong River for free shrimp fishing. , what's going on?

First of all, let’s talk about the Mekong River. Many Chinese people probably know the name of the Mekong River from the movie "Operation Mekong River". In fact, in addition to the movie "Operation Mekong River", the Mekong River also has a lot of connections with our country. The source of the Mekong River is the Tanggula Mountains in my country. In China, the Mekong River is what we often call the Lancang River.

The Mekong River is a large river that spans many countries. Laos, Myanmar, Thailand, Cambodia and Vietnam are all nourished by the Mekong River. The water quality of such a large river that spans many countries is actually quite good under the protection of many countries. The good water quality has nurtured farmland vegetation along the coast and also raised shrimps. The shrimp is big. An adult shrimp is as big as an adult's palm, weighing about a pound. It grows very fast. This is second to none. The most important thing is that the shrimp has a very wide food habit. In layman's terms, it eats everything. Can be eaten. It can be eaten, grows, and reproduces quickly. In addition, it tastes delicious. The large shrimp heads have a taste similar to crab roe. The shrimp is still very popular in our country.

It is cultured in many places in southern my country, but Romanian shrimp is not a native species to us. Most of the Romanian shrimp introduced into our country come from Thailand and Myanmar. Since the Mekong River in Vietnam is overrun with Romanian shrimp, why was it not imported from Vietnam? What about Roche shrimp? Because Vietnam is not the origin of the shrimp, the shrimp in the Mekong River in Vietnam is an alien species, which is what we often call biological invasion. The consequences of biological invasion are very serious. Famous cases include the introduction of rabbits into Australia to facilitate hunting. As a result, farmland vegetation throughout Australia was destroyed by rabbits. Rabbits are not native to Australia. When rabbits were introduced, Australia had no natural enemies of rabbits. Rabbits reproduce very rapidly, leading to an epidemic of rabbits.

Australia once tried to build 1,000 kilometers of fences to prevent rabbits from reaching Western Australia, but all failed. Grassland crops in most areas were destroyed by rabbits and even caused soil erosion. In the 20th century, Australia has been In the midst of a rabbit eradication campaign.

The famous invasion of alien species in my country is the invasion of water hyacinth. my country's water hyacinth once grew everywhere in rivers in many provinces, destroying the water quality of my country's lakes and rivers and affecting the growth of native aquatic organisms. Our country has also thought of many ways to manage water hyacinth, such as using it as traditional Chinese medicine, feed, fuel, fertilizer, and also making water hyacinth into a drink. After a multi-pronged approach, the biological invasion of water hyacinth in my country was finally controlled and resolved.

However, Vietnam has no effective solution to the flooding of shrimps. First of all, although shrimps are a delicacy for our people, Vietnam does not have many suitable cooking methods. , Vietnamese people are not very keen on eating shrimp. Secondly, the shrimps reproduce and grow very fast, and no matter how much they are hunted and killed in Vietnam, they cannot keep up with the reproduction and growth rate of shrimps. Although people are allowed to fish for shrimps for free, it is really a drop in the bucket for the shrimps in the river.

Someone once suggested that we Chinese foodies should eat the shrimps that are flooding in the Mekong River, but I am afraid that not many Chinese people dare to taste them. Why is this? We must know that one of the reasons why water hyacinth floods rivers and lakes in our country is due to the indiscriminate discharge of industrial wastewater in our country. So besides the lack of natural enemies for the reproduction of shrimp in the Mekong River, is there also a problem with the water of the Mekong River? Secondly, although the Mekong River is a transnational river that spans many countries, most of the Mekong River basins are filled with waterfalls and rapids, which are not suitable for ships to travel, which is naturally not conducive to the transportation of shrimps.

In addition, the transportation requirements for shrimps are relatively strict. If the temperature is too high during transportation, shrimps will die or rot quickly. And in comparison, crayfish has a bigger market in my country, and people love the taste of crayfish more. Therefore, few Chinese people are willing to eat the shrimp that is so prevalent in Vietnam. And if the Chinese people were asked to go to the dangerous Golden Triangle of the Mekong River to eat a meal of shrimp, I am afraid many people would not dare. This is why even though there are many shrimps, few people eat them. Everything should be done in moderation. Although there are also farmed shrimps in our country for people to enjoy, it is too much and not enough to cause biological invasion without checks and balances.
