A "strange fish" stirs many chaos: buy online and offline, the invasion list is not there

On August 27th, more than a month, Ruzhou, Henan, took off the water of Yunzen Lake, and finally captured the "strange fish" -the crocodile bird. The huge pumping operation has attracted widespread attention. In Qingdao and Jiangsu Nantong in Shandong, the trace of crocodile crickets has also been found recently.

Crusadus is native to North America. It is a giant carnivorous fish in freshwater. It has strong fertility and lacks natural enemies in my country, which is in line with the basic characteristics of foreign invasion species. In recent years, this "uninvited guest" has frequently caused trouble, repeatedly settling, and sounding the alarm for the prevention and control of foreign species invasion.

In order to catch a fish, take dry a lake, and move the Gan Ge to ask: Who cares about foreign species? How to improve identification and processing capabilities in the face of foreign invasion species? Xinhua Daily · Jiaojiao reporter launched an investigation.

A piece of crocodile cats seedlings nine pieces and nine free shipping

"Praise, let's eat it in the tank for a while!" "Yes, the fish is active." Comment. In Taobao's "Fishfish Water Fisheries Store", more than 400 people pay for more than 400 people. 5 to 7 cm of fish fry, the price is only 9.9 yuan, and it can also be shipped.

According to the store, the scientific name of the crocodile is crocodile, and reminded: "This fish grows fast, the longest in the fish tank can grow to more than one meter. The fish that is smaller than it may be eaten. The mixer is quite or larger than its body. "

Not only is it easy to buy online, but also "walking" everywhere. On August 29, Nantong's Agricultural Comprehensive Administrative Law Enforcement Detachment seized 5 and 18 crocodile crickets in the Dragon Hair Zhongnan Store and Guanyin Shan Store. In these two stores, all of them were sold as ornamental fish. In the Nanjing Qiqiao, flowers, birds, fish and insect markets, reporters visited a number of aquariums selling tropical fish and found that almost every store had crocodile crickets on sale, and the fish was about 200 yuan in length of about 40 cm. A shop saw that the reporter stayed in front of the crocodile catfish tank, and immediately stepped forward to recruit enthusiastically.

The reporter's investigation found that crocodile crickets are only the "corner of the iceberg" of living trading of foreign species. In May of this year, based on the survey of the biological diversity of the province's county, the Provincial Department of Agriculture and Rural Affairs, through risk assessment and screening, jointly compiled the "List of Foreign Invasion of Jiangsu Province (First Batch)" There are 32 types of invasive species, 8 key species I control and control, and 24 general management and control species. Among them, some foreign invasive species are clearly included in the list of Jiangsu Province, such as Brazil's red ear turtle, depending on the size, ranging from 10 to 30 yuan on the e -commerce platform; The price of fish seedlings of 1.5 cm is only 12.8 yuan; there is a year of fluffy, and it is mostly "packaged" for flying grass, and a pot is about 18 yuan. The reporter asked a shop privately: "Why can Brazil's red -ear turtles be sold as foreign invasion species?" The store replied: "It can be sold on the shelves.

Dai Weimin, deputy director of the Department of Botanicals of the School of Life Sciences of Nanjing Agricultural University, participated in the preparation of the first batch of foreign invasion species in Jiangsu Province. He introduced that in the past, foreign species entered the country through international trade and viewing. In recent years, with the rise of cross -border e -commerce and international express delivery industries, foreign species have entered more channels. Foreign species are also used as "alternative pets" to benefit the interests, which exacerbates the risk of spreading and diffusion of foreign species.

"The wrong release is killing"

Foreign species spread widely in the wild, the root cause is people.

Tang Zhebin, 56, is the captain of the three detachments of the Law Enforcement Corps of the Nanjing Agricultural and Rural Bureau. He has been engaged in fishery administration law enforcement work for many years. Residents' release behavior is also common, and there are crocodiles. "

"I thought that release can accumulate virtue and good, and resolve disasters is actually an act of affecting the ecology." A member of the Nanjing Suiyuan Release Protection Group told reporters. A number of civil groups such as the Kunshan Reanning Alliance in Jiangsu Province, the Yangzhou Chou Aishe Nights Group, and the Heart of Xuzhou Bodhi will regularly organize release behavior. The reporter randomly asked some members. Lack of cognition for foreign species.

According to the analysis of the associate researcher of the Pearl River Aquatic Research Institute of the Chinese Academy of Aquatic Sciences, from the perspective of the current distribution of the point -shaped distribution of the place where the crocodile is found, the probability of the crocodile crickets in the natural waters is more likely to release. After breeding, because the growth rate is too fast, the aquarium cannot accommodate or is unable to bear the cost of breeding and is artificially released or discarded.

The disorderly release has become an important part of the invasion of the local environment. In June last year, Nanjing started a systematic biological diversity ontology survey for the first time. Among them, it was found that an algae that had never occurred in Nanjing in the past, expanded rapidly, and inhibited local creatures. Dai Weimin's team survey found that the algae grows in tropical areas and is sold in some aquariums. It is speculated that the tropical algae in Nanjing's natural waters is discarded after manping.

"Dozens of dead fish drifting in Wuxi Lake, suspected of being blindly released" "disaster", "Shanghai Suzhou River frequently discharged a large number of dead fish because of blind release." Zhao Xumao, a youth researcher at the School of Ecology, Lanzhou University, analyzed that after humans intentionally or unintentionally brought foreign species into the scope that does not belong to its natural distribution, it may achieve breeding and establishing species, leading to local species of genetic pollution, decreased population, local extinction or extinction. For example, as a year of sale of ornamental plants, an e -commerce platform can produce an average of 10,000 to 50,000 seeds per planting period of each plant. The strong reproduction capabilities make it occupy the living space of local plants. "The wrong release is killing." Tang Zhebin said that some people often asked during the law enforcement process, why the officials often proliferated and released, but they were not allowed to release them. The Yangtze River proliferation release is a systematic science. How many fish, what fish, the size, size, quality, etc. also have certain requirements. Experts need to formulate a proliferative release plan based on the investigation. The citizens are likely to have unintentionally released foreign invasion species due to the lack of professional knowledge. For example, many field snails are mixed with invasive species Fu Shou snails.

It can be based on the law but illegal

In fact, there is a law to rely on foreign species. In the past two years, my country has promulgated the "Biological Safety Law of the People's Republic of China" and the "Administrative Measures for Migraphic Invasion Species", which provisions on source prevention, monitoring and early warning, and reimbursement of governance. However, people in the industry believe that a small crocodile crickets have exposed issues such as relevant regulations that need to be implemented in detail.

"Although the law stipulates that any units and individuals shall not be introduced, released or discarded by foreign species without approval, they do not clearly prohibit the introduction, purchase and sales of foreign species. Selling information of foreign species. "Chen Bin, a lawyer of Jiangsu Taihe Law Firm, believes that the cash control of foreign species is currently very strict, but it still needs to be further standardized in breeding and sales. The supervision and management of related markets such as the aquarium, pet market, and breeding market should be strengthened. E -commerce platforms also need to establish an audit system urgently. Personal breeding of foreign species should register real -name systems.

From the perspective of the professor of the law school of Nanjing University, the punishment of foreign species operators has not yet been clarified, but when the trading behavior directly trigger or promotes illegal introduction, release or discarding Essence In order to effectively curb the threat of such acts on biological safety, legislation needs to further improve the relevant system and regulatory measures.

At the implementation level of relevant regulations, there are many "blind spots". The "Regulations on the Management of the Yangtze River Aquatic Biological Protection" implemented from February 1 this year prohibit the opening of waters in the Yangtze River Basin to breed, put on foreign species or other non -local species. However, the relevant person in charge of Nanjing Binjiang Park Management Co., Ltd. admits that the Yangtze River Bank Line is very long, and it is difficult for the staff to find out who released or discard foreign species without authorization. The illegal cost is almost zero.

In the process of handling the case in Taizhou Procuratorate

"Because foreign species invasion invasion is wide, the latent period is long, and the difficulty of tracing the source is difficult. It is difficult to find a specific infringement subject, or the infringement subject is difficult to determine the defendant's identification. Liu Yan, a full -time member of the Procuratorate of the People's Procuratorate, said that in response to the situation of threatening local biological safety such as a yellow flower and Fushou snail in Canada, the Taizhou People's Procuratorate organized seven grassroots institutions in the city to carry out special inspections of biological safety public interest litigation, and timely to the functional departments and the functional departments and the The local government issued a pre -procuratorial proposal to issue a public interest lawsuit to urge them to organize effective prevention and elimination work in a timely manner to avoid the rapid spread of foreign invasion species.

Foreign species governance "should be tight or not loose"

During the survey, the reporter found a surprising fact -as of now, the Ministry of Ecology and Environment and the Chinese Academy of Sciences have announced a total of four batch of foreign invasion species. Although crocodiles are foreign species, they are not in the list of invasive species.

"Whether foreign species have invasion attributes need long -term scientific assessment." Dai Weimin said, for example, the water gourd introduced as pig feed was flooded in Jiangsu and even the country. Due to the rapid breeding and expansion of the interoperable rice grass introduced on the coast of Jiangsu, it has affected the wetland beach coating and obstructing the vessel road, bringing huge economic losses. Although the academic community has not given authoritative conclusions whether some foreign species will constitute biological invasion risks, he suggested that the governance of foreign species should be tight or not. To establish an early warning mechanism, a forward -looking assessment of the risk consequences of possible invasion of foreign species. Because once the invasion of invasion in the future, the destruction of the ecosystem will be irreversible.

"The influence of foreign species on the local ecology can not be judged overnight, so whether the invasion of the invasion should be updated dynamically." Wang Beixin, director of the Insect Department of Nanjing Agricultural University School of Protection. This year, the Ministry of Agriculture and Rural Affairs and other relevant departments formulated the "Notice on Printing and Distributing the General Plan for Foreign Invasion Species Census", and 10 major migrant aquatic creatures conducted national census, including crocodile crickets. The "Administrative Measures for Foreign Invasion Species", which have been implemented in August this year, also clearly stipulates that the establishment and monitoring system of foreign invasion species will be established, and the national census will be organized every ten years to build a national foreign invasion monitoring network.

Clarifying the boundaries between "foreign" and "invasion", Jiangsu relevant departments have launched actions.At present, the Jiangsu Provincial Institute of Freshwater and Aquatic Products is conducting a census of foreign invasion of aquatic animals.Li Dahu, deputy director of the resource and environmental research office of the institute, introduced that the research team went to Lake Lake from August 11th to 13th to carry out a census survey of aquatic animal invasion.Investigating points, focusing on 10 foreign aquatic animals such as Qi Luo Fei fish, crocodile bird, mosquito fish, Fushou snail, and bullfrog.Xu Tianjiao, director of the soil and ecological department of the Nanjing Ecological and Environment Bureau, reminded that in the face of foreign species, the whole society must be vigilant. Everyone should start from themselves, establish a sense of ecological protection, strictly abide by relevant laws and regulations, and do not buy foreign "different" differences."Pet", do not bring in the country from overseas, and those who have already purchased can not be released at will, and jointly build a line of defense to maintain ecological security.
