<h1 class="pgc-h-arrow-right" >1, the event passed</h1>
Recently, the Public Security Bureau of Nenjiang City, Heilongjiang Province, successfully cracked a case of illegal fishing of aquatic products, seized more than 370 jin of illegally caught aquatic products on the spot, and then returned to nature with the cooperation of the staff of the Nenjiang Fisheries Bureau.
It turned out that Li, Jiang and Hou had discussed with each other and wanted to catch the cockroaches in the waters of the Machang River to earn some extra income, so they got a van and purchased more than 50 flower nets for crime.
In order to effectively protect the safety of the people's lives, health and property safety, the three people were taken criminal compulsory measures in accordance with the law, and after interrogation, the three criminal suspects confessed to the illegal and criminal acts of illegal fishing for aquatic products and slugs.
Article 340 of the Criminal Law of the People's Republic of China, the crime of illegal fishing for aquatic products refers to the violation of laws and regulations on the protection of aquatic resources by fishing aquatic products in a prohibited fishing area, during the fishing ban period, or using prohibited tools or methods, and if the circumstances are serious, shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention, public surveillance or a fine. At present, the case is still being further handled.
< h1 class="pgc-h-arrow-right" >2, why were you caught? </h1>
The main target of these 3 people is the cockroach, which is what we call the Northeast Crayfish, also known as the big head shrimp, the shrimp, there is a geographical restriction, that is, the crayfish living in the northeast, we must not think that it is the kind of spicy crayfish we usually eat!
Although the cockroach is also an aquatic crustacean, the appearance and size are very similar to the crayfish we usually eat, but it is the representative of China's "freshwater lobster", there are currently 4 species of cockroaches, of which 3 species only live in the mountain streams or rivers and lakes in the northeast region.
They are very demanding on the environment of the waters they live in, and the slightest pollution can lead to death, based on the large-scale use of pesticides and the deterioration of the environment in some areas, and there is no trace of the cockroach in many rivers.
Although the population of the cockroach has declined sharply, it is not currently included in the scope of protected animals, but this is not a reason to catch them at will, and the three people use prohibited fishing gear for extinct fishing, which will certainly cause serious harm to the existing population of cockroaches.
< h1 class= "pgc-h-arrow-right" >3, how to distinguish between native shrimp and invasive shrimp? </h1>
In fact, in the end, the two are related, the same belongs to the animal line - arthropod phylum - crustacean - decanter day - abdominal embryo suborder - crawfish family, but the cockroach is the genus of cockroaches, orthogonal crawfish family, Crawfish is the genus of protoceps, crawfish family.
It is said that ginseng, mink skin, deer antler horn is the three treasures of the northeast, but from the above introduction, it can be seen that the northeast crayfish is actually a small treasure, the appearance can be roughly referred to the spicy crayfish held in the hand, but the essential difference is that the cockroach is a native lobster, and what you have in your hand is an invading crayfish.
How to distinguish is the key, otherwise in case you see crayfish in the wild, is it fishing or not fishing? Of course, the most essential difference is that the Northeast crayfish is generally not seen or eaten, and although the price of the crayfish you hold in your hand is increasing year by year, you can often eat it with a little effort.
Northeast crayfish live in the northeast, and Crawfish native to North America, is an important species of freshwater shrimp farming in the United States, in 1918, Japan introduced from the United States as bullfrog feed, since then crayfish have gained a foothold in Japan, and led to the disappearance of black crawfish native to Japan. During the Japanese invasion of China, the Crawfish was brought to China, and since then Pandora's magic box has been opened, and the invasion of crayfish is deeply rooted and is now widely distributed in the middle and lower reaches of the Yangtze River in China.

How to distinguish between two shrimps whose origin is unknown? The quickest and most direct way is to look at the shell! The shell of Crawfish is brownish red with distinct nail spines and protrusions, with short, thick parapods and large heads. The shell of the northeast crayfish is blue-green, the appearance is smooth and there are no obvious bumps and nails, the parapods are slender, and the tail is large.
After eating it, you will find that the pain really comes from the comparison, because the earthy taste of the Crawfish is rich and fishy, while the Northeast Crayfish tastes delicious and slightly sweet. This is mainly related to the living environment of the two, and rural people know that Crawfish is very adaptable to water quality, even if the fertilizer and pesticide are so popular, they still crawl in the field. The northeast crayfish specialize in eating water worms, small fish, aquatic plants and plant grains in the mud of rivers and streams, which is more delicate, and any pollution will lead to death.
< h1 class = "pgc-h-arrow-right" >4, there is still a long way to go to protect native shrimp</h1>
People get the horn for nothing more than to satisfy the appetite, it is rich in nutrients, rich in magnesium, can protect the cardiovascular system. The flesh is soft, easy to digest, and very friendly to people after physical weakness. It has a strong lactation effect, is rich in phosphorus and calcium, and has obvious tonic effect on children and pregnant women. Recently, scientists at Osaka University in Japan have also found that astaxanthin in the body of the lath helps eliminate the "jet lag" caused by the jet lag reaction.
So in ancient times, the latch was provided as a superior tribute to the imperial palace, in recent years people continue to pursue green and healthy food, and the northeast crayfish is gradually favored by many foodies, there is a demand in the market, some local mountain people for economic benefits, but also constantly ask for latches from nature.
In the process of buying and selling, some people are carried away by the interests, change the method to catch more hornworms, in order to get more in the short term, they use drugs to detoxify, not only let the original non-polluted horns remain toxins, but also destroy the environment for the breeding and breeding of hornflies, we do not want the horns to be listed as a national protection activity like giant pandas, but the actual situation is that the horns are on the verge of extinction.
The reason why it is not included in the list of protected animals is because it has not yet met the corresponding standards, according to the relevant provisions of China's Wildlife Protection Law, even if the hornworm is counted as a precious and endangered wild animal, its ecological, scientific and social value has not yet been assessed in a statutory amount. Most of the wildlife protection list in China are larger animals, which may be updated slowly, and small animals such as shrimp and crabs are basically not covered at present.
The Northeast crayfish all live in streams or rivers in inaccessible primary forests, inhabiting rock crevices or vegetation, extremely hidden, and timid, once found will quickly flee, so in the short term to assess the number of wild populations, it is a great challenge.
In 2017, China ate 979,500 tons of crayfish (crayfish), even if the crayfish industry in 2020 fell by 15.06% year-on-year, its total industrial output value was also 349.07 billion yuan. There is a market for aquaculture, of which rice field aquaculture has the largest output, 1.1865 million tons, and the aquaculture area reaches 12.61 million mu.
So many artificially farmed crayfish, it is certainly unrealistic to say that there is no escape, and after a flood, the crayfish can flood in the wild, or even eradicate, and now the crayfish has been widely distributed in 19 provinces and municipalities in China, including the northeast region. And all this, many foodies have an unshirkable responsibility!
These invasive crayfish are inherently viable, and with their super-fast reproduction rates, they are a threat to native shrimp. The native northeast crayfish is caught by humans and attacked by foreign invading crayfish, the living space is shrinking day by day, and the population is seriously reduced, so it is a long way to protect the native freshwater crayfish.
