Introduction: Thick as an arm, the "giant shrimp" flooded abroad has been found in the wild many times, and anglers have caught several fishes in a row
Speaking of shrimp, it is a kind of river fresh that many people love to eat.
In recent years, crayfish can be said to have done their best, and when the summer crayfish is on the market, the streets and alleys are full of clamoring for crayfish, or crayfish-based delicacies, and even the supper stalls have occupied the C position for a long time.
But in recent years, a giant shrimp has also followed suit and invaded our country, it is as thick as an arm, up to a meter long, and a single weight can grow to more than 1 kilogram.
It has already been flooded abroad, and now it has appeared in many waters in the south of Our country, and many anglers have caught this giant shrimp one after another.
Is this giant shrimp going to grab the limelight of "crayfish"? Netizens said: This is all here to deliver dishes!
<h1 class="pgc-h-arrow-right" data-track="43" > Giant river shrimp invaded the Pearl River and other water systems</h1>
This giant shrimp that wants to grab the limelight of crayfish is the Giant River Prawn from Southeast Asia, also known as Thai shrimp, freshwater long-arm prawns, Malaysian prawns and so on.
This is a relatively large shrimp of the genus Macrobrachia in the family Long-armed shrimp family and giant river shrimp. It has been introduced abroad for many years and is a notorious shrimp in the Mekong region, only because the local Giant River prawn has been flooded for many years.
In recent years, wild giant river prawns have also appeared in many provinces in southern China, which are concentrated in some wild rivers and reservoirs in Guangdong, Guangxi, Fujian and other provinces.
In the past two years, some anglers have reported that a giant shrimp was caught in the wild, which weighed nearly a pound and was as thick as an arm.
However, its body color is bluish blue with brownish-yellow stripes, and it is mostly azure blue, which is quite different from the river shrimp usually seen in China, both in terms of body shape and body color.
And these giant shrimp are the giant shrimp that flooded abroad in the early years - Giant river prawns.
<h1 class="pgc-h-arrow-right" data-track="44" > where does giant shrimp roche in the wild come from? </h1>
In the northern region, it may be difficult to see giant river prawn, but it is still relatively common in the aquatic markets of many southern cities.
It is also a popular freshwater shrimp.
In fact, as early as the 1960s, many countries in Europe and the United States have begun to introduce and cultivate Giant River Prawn.
China also introduced Giant River Prawn from Japan in 1976 and tried to cultivate it in Guangdong, Fujian and Guangxi provinces in the south.
The reason is because of the rapid growth rate of Giant River Prawn, the meat is delicious, the nutrition is also delicious, and it is a shrimp with high economic value.
In recent years, with the continuous maturity of technology, the number of farmers who cultivate Giant River Prawn is also increasing, and the scope of farming is also expanding. At present, the price of giant shrimp in the market is also considerable, generally sold to a price of 40-60 yuan a catty.
Since some people are farming, some will escape to the wild, and when the water rises, or the typhoon comes, a large number of Giant River Prawns will escape to the wild environment.
The Giant River Prawn has been farmed in China for nearly 50 years, and has long been adapted to the growth environment of our country, when the farm's Giant River Prawn escapes to the wild, they can continue to grow if they are suitable for the wild environment.
It is not difficult to understand why there are anglers who have caught such large "giant shrimp".
<h1 class="pgc-h-arrow-right" data-track="45" will > follow in the footsteps of crayfish? </h1>
For many anglers who have caught wild Giant River Prawns in the wild, and even some people have caught Giant River Prawns full of shrimp eggs, does that mean that they have adapted to the wild environment, and then like abroad, Giant River Prawns will also flood in China?
In fact, this is unlikely, and giant river prawns are unlikely to flood like crayfish in China.
First, Giant river prawns are less adaptable than crayfish.
Although they are all invasive species, but the adaptability of Giant River Prawns is not too strong, especially sensitive to water temperature, the temperature is high they can not survive, and the temperature is low is also difficult to survive, so even if they escape to the wild, but in the winter survival is worrying.
However, crayfish can naturally overwinter in the wild in the south.
Secondly, it is difficult to reproduce naturally in china. The reproductive ability of crayfish is amazing, and they can reproduce naturally in the wild.
However, giant river prawns are far worse than crayfish in this regard, and the currently farmed giant shrimp are also bred by artificial intervention, and it is still difficult for them to reproduce naturally in China's environment.
Even if there are some Giant River P. rochaemonii eggs in the wild now, it is very likely that the farm has escaped from the breeding of Giant River Prawns. In the wild, they are not yet able to reproduce naturally.
Finally, Giant River Prawns are delicious and attractively priced. Giant river prawns farmed in the market have always been very popular, even if they sell for more than 40 yuan a catty, but many people still like to eat it very much.
Since it is so delicious, will it have the opportunity to flood in the wild? As some netizens commented: these Giant river prawns are all here to deliver vegetables.
Some netizens said bluntly that such delicious shrimp can also be flooded.
Of course, this is a joke.
<h1 class="pgc-h-arrow-right" data-track="46" > concluding remarks</h1>
Giant river prawns must crush the shrimp native to China in terms of size and predation. If it is really flooded, it will also have a great impact on the ecological environment of our country.
However, as far as the current situation is concerned, the Giant River prawn that floods in the Mekong River has a very slim chance of flooding in China, but it still needs to be paid attention to.
Friends, have you ever fished for wild Giant River Prawns? Do you have people in the local area who breed this giant shrimp, do you like to eat this shrimp? Welcome to leave a message to discuss.
