In the face of the "invasion" of alien species, each country in the world has a different performance, because some of these alien species enter unintentionally, and some are actively introduced.
For our country, some exotic species have also been introduced, and their arrival not only enriches our table, but also provides us with a certain economic reward.
Recently, some netizens sent a photo of the fish to the editor, which is not the common freshwater fish such as crucian carp, carp, grass carp, etc., but a fat freshwater shrimp, and the weight of this shrimp is almost close to 1 catty.
As the saying goes: "Big fish eat small fish, small fish eat shrimp and shrimp", the shrimp living in freshwater is a relatively small creature, this body size is close to 1 pound of freshwater shrimp, Xiaobian is also the first time to see, so it is also the first time to check the relevant literature, and it was found that the origin of this shrimp is not simple.
Relevant literature shows that the scientific name of this freshwater shrimp is giant river prawn, which is native to the Mekong River, so the locals also call it Mekong river shrimp, this shrimp belongs to a large shrimp species, which can reach the length of an arm when it is an adult, and the weight of a single one can reach more than 1 catty, and its meat is firm and delicious, which is very popular with the majority of diners.
This kind of Mekong shrimp is compared with our native freshwater shrimp, these freshwater shrimp in our country can be described as veritable small shrimp, as for this Mekong shrimp can grow to such a big size, in addition to the species, and their living environment should also be directly related.
Geographically, the Mekong River originates on the northeastern slope of China's Tanggula Mountains and is called the Lancang Jiang or Lan-ts'ang Chiang in China, and the section of the river that flows into the Indochina Peninsula is called the Mekong River.
The Mekong River covers a wide area, spanning many countries in Asia, and at the same time serves as the main artery of other tributaries, with abundant food and suitable ambient temperatures, so that Mekong shrimp have a suitable living space and a great opportunity to grow.
Thanks to the unique resource conditions of the Mekong River, Southeast Asian countries such as Myanmar have added shrimp fishing as an entertainment project while developing their tourism economy, and tourists will go to these Southeast Asian countries every year to experience the charm of shrimp fishing.
In the Guangdong area of the mainland, there are also many local shrimp fishing restaurants, which use this kind of Mekong shrimp, and there are also related breeding bases in the southern part of the mainland.
In addition to the Mekong shrimp that can be seen in captive farming and shrimp fishing houses, in recent years, there have been frequent catches of this Mekong shrimp in some natural waters on the mainland.
In July 2019, Mr. Zhang, a fisherman who traveled to Hainan, caught a "prawn" about seven taels of "prawns", which was recognized by netizens as Mekong shrimp after being posted on the Internet.
In late October 2021, Mr. Wang from Sheyang County, Yancheng City, Jiangsu Province, was fishing for crucian carp in the small river in front of his house when he accidentally caught a Mekong shrimp about 3 taels, and the shrimp had shrimp eggs in its abdomen.
We can learn a lot about Mekong shrimp on the Internet, and in recent years, they have been found in many waters of the mainland.
In this regard, some netizens expressed concern, because everyone knows the harm of "invasion" of alien species, will such a size of Mekong shrimp cause damage to natural waters?
As far as the current situation is concerned, although the Mekong River has been discovered one after another, they are mainly caught by some anglers by accident, and the overall number is not huge, which may be related to the escape of aquaculture, but whether they have been able to thrive in the natural waters of the mainland, there is no relevant evidence at present.
At the same time, this Mekong shrimp has a high economic value, the selling price in the aquaculture production area is about 30 yuan/catty, and the selling price was once as high as 50 yuan/jin after being transported to other places, in the face of such a high economic return, farmers are often trying to prevent them from escaping, as for the Mekong shrimp that flow into natural waters, once it is found, it is difficult to escape.
However, some netizens are full of expectations for Mekong shrimp, looking forward to them being able to "flood" in natural waters as soon as possible, because they can enjoy the fun of fishing for prawns, and at the same time eat "cheap" prawns.
I don't know if you have seen or eaten Mekong shrimp, do you think they have a chance to "flood" for the "invasion" of this alien species?
