What's the situation?
Is It not cruel enough for Chinese foodies?
Or are crayfish more ruthless than Chinese foodies?
Obviously this season's circle of friends,
It has become the circle of friends of crayfish
On May 21, Yunnan released the List of Invasive Alien Species in Yunnan Province (2019 Edition) (hereinafter referred to as the "List"), which is the first provincial invasive alien species list in China.
The so-called invasive alien species refer to alien species that have formed self-regenerative ability in local natural or semi-natural ecosystems, and may or have caused obvious damage or adverse effects to the ecological environment, production or life.
The "List" released by Yunnan this time divides invasive species into 5 categories, including grade I malignant invasive species, grade II. severe invasive class, grade III local invasion class, IV. general invasive class, and V. class to be observed.
Among them, the grade I malignant invasion class includes micro-chamomile, hyacinth blue (water hyacinth), brown cloud agate snail, small tube Fushou snail and so on. American cockroach (giant cockroach), protocellfish (crayfish), bullfrog, etc. belong to the class II serious invasive class.
Crayfish, bullfrogs...
Level II Critical Intrusion Class?
Are you kidding!
It's all about it
Chinese delicious on the table!
Netizens have something to say about this:
One person kills a few pounds at a time,
Not a problem at all!
Crayfish on the list,
It is an "insult" to our foodies!
The reason it's not gone extinct yet is it too expensive?
Maybe they were eaten as "second-class"!
Maybe it's more ways to eat
It hasn't been developed yet.
And the publicity is not in place?
Of course, some netizens realized that
Species invasions are serious indeed.
And at the moment,
Crayfish that can be Chinese table,
It is still mainly based on aquaculture.
Is it the experts who are making a fuss?

Crayfish are more than delicious
The scientific name of crayfish is protocellfish, also known as red crawfish or freshwater crayfish. Professor Cai Shengli of the School of Fisheries of Shanghai Fisheries University introduced that crayfish are native to North America, and at the beginning of the last century, Japan introduced crayfish from the United States as a bait for raising bullfrogs.
Later, crayfish were introduced to China from Japan and have now become an important resource in China's freshwater shrimp, widely distributed in the provinces and cities in the middle and lower reaches of the Yangtze River.
In life, most people only know that crayfish are delicious, but they do not know that crayfish have lung flukes, which is easy to cause "rhabdomyolysis".
In general, animals such as crayfish and crabs carry lung flukes, and roasting, stir-frying or pickling does not guarantee the killing of lung fluke larvae. Therefore, eating crayfish must be cooked thoroughly.
In addition, astaxanthin in the crayfish is an antioxidant, and the darker the color, the higher the astaxanthin content. Astaxanthin is widely used in cosmetics, food additives and pharmaceuticals, which can be described as a wide range of uses. As a result, crayfish have been introduced to some countries and bred in large numbers, ignoring the harm caused by invasive alien species.

"Eating" cannot be solved
Invasion of alien species
In recent years, Asian carp have been breeding wildly in the United States, threatening the local ecological balance. However, as a material for Chinese cooking, carp is deeply loved by the Chinese people. After learning of the flood of carp in the United States, many netizens said, "Let domestic foodies solve it."
Coincidentally, the alien species crayfish that invaded China is also a delicacy on the Chinese table. This makes many netizens believe that the reason why invasive species are flooded is mainly because they have not developed a "way to eat".
This view is clearly biased. Liao Wanjin, a professor at the School of Life Sciences of Beijing Normal University, said that "foodies" can solve all problems?

China's customs have seized it many times this year
Invasive species
The tricky situation facing Yunnan is a microcosm of the situation of species invasion in China. China is one of the countries most affected by invasive alien species, and customs often detect invasive species during inspections, with many cases occurring this year alone.
In March this year, when the customs officers of Guangzhou Baiyun Airport under Guangzhou Customs inspected the inbound baggage carried by an African student, they found two live African snails in his bag. The African giant snail is known as the "pastoral killer", and the person concerned said that he wanted to declare customs as a pet.
In April, when inspectors at the Qianjiang Customs Post Office under Hangzhou Customs conducted a routine inspection of incoming mail, they found an abnormality in a piece of mail from Spain. After opening the box, it was found that there were 8 small boxes containing more than 200 live rat women.
In the same month, Chengdu Customs seized eight live scorpions. This batch of scorpions came from the United Kingdom's undeclared product name entry mail, the image was abnormal when passing the X-ray machine, and when it was opened, it was found that there was a scorpion in each of the 8 storage boxes. After testing and identification, it belongs to the South African flat stone scorpion, native to South Africa, with weak toxicity, gentle temperament and slightly neuroticism.
Although the crayfish taste delicious,
But I would like to remind you:
Face up to the seriousness of the "species invasion" problem!
