In June, the Guiping Agricultural Comprehensive Administration Law Enforcement Brigade Fisheries Administration Squadron went to the site for verification and confirmed that the fish was a crocodile gar, and initially formulated a catch plan. However, the local rainfall in June and July is relatively large, and the lotus pond in the scenic spot is connected to the water source on the top of the mountain, so it is impossible to drain the pond water for fishing.
On the morning of August 25, after the pool was drained, two ferocious alligator gars were caught, weighing 7.02 kg and 8.32 kg respectively.
On the morning of the same day, the Fishery Squadron of Guiping Agricultural Comprehensive Administration and Law Enforcement Brigade processed alligator gars as specimens.
There are a lot of alligator gars in the local aquarium
On August 27th, in a large aquarium shop in Nanning Flower and Bird Market , the reporter found alligator gars sold as ornamental fish .
The alligator gar has a strong predation ability and can eat fish smaller than it in one bite.
Later, when the reporter visited the flower and bird market in Guangxi, he found that almost every aquarium store was selling alligator gar, and the price was 25-40 yuan per piece according to different specifications. The merchant said that the crocodile gar can grow up to 3 meters. When selling it, he will remind consumers to "don't let children reach into the fish tank" and "don't release them, otherwise it will be a sin."
In an aquarium store in Nanning Flower and Bird Market, citizens are choosing pet fish, and alligator gars are also sold in the store.

Be vigilant! These invasive alien species
In recent years, the number of invasive alien species in my country has been on the rise, becoming one of the countries most seriously affected by the invasion of alien species in the world. According to the "2020 China Ecological Environment Status Bulletin": more than 660 invasive alien species have been discovered in my country.

water hyacinth is native to South America. It was introduced to my country as an ornamental plant in the early 20th century, and was later popularized and planted as pig feed. Because of its mass reproduction, it often spreads all over the rivers and lakes, resulting in a large number of aquatic plants. Organisms die due to lack of oxygen and sunlight, destroying the ecological balance in the water.
02 " Goldenrod "
"Canadian Goldenrod" is an ornamental plant introduced from North America in the 1930s in Shanghai and other places. , destroying the ecological balance of vegetation in the invasive land.

RIFA is my country's agriculture, forestry and imported phytosanitary pests, and it is also one of the 100 most dangerous invasive species recognized globally. RIFA can directly eat the seeds, fruits and buds of crops, which will reduce the yield of crops and affect the growth and reproduction of some animals. At the same time, incidents of RIFA injuries also occur from time to time.
05 Fushou snail
Fushou snail, also known as large bottle snail , apple snail , originated in the Amazon River Basin of South America. Introduced to China as edible snails in the early 1980s, it has become an invasive alien species with great harm due to its strong adaptability and rapid reproduction.
06 Spodoptera frugiperda
Spodoptera frugiperda is a migratory pest warned by the Food and Agriculture Organization of the United Nations (FAO) globally. Serious harm to the growth of crops such as corn. In 2019, Spodoptera frugiperda invaded my country for the first time.

Cannibal pomfret
In July 2012, Zhang Kaibo, a citizen of Liuzhou , was bathing his puppy in the section of the Liujiang River when he was attacked by three ferocious fish, and his palm was bitten and bleeding. After the fish was caught, the expert team identified the fish as the mulberry carp native to South America. It is a kind of man-eating pomfret and a ferocious carnivore.
Regarding the issue of invasive alien species, my country's management system is constantly improving. " Administrative Measures for Invasive Alien Species " will come into force on August 1, 2022.
The method is clear, the Ministry of Agriculture and Rural Affairs will establish a census system for invasive alien species together with relevant departments, and organize a national census every ten years; establish a monitoring system for invasive alien species, and build a national invasive alien species monitoring network; establish a information release system for invasive alien species .
The solution to this problem also depends on the efforts of society and individuals to prevent the invasion of alien species, and it is everyone's responsibility. The "Biosafety Law of the People's Republic of China" stipulates that: no unit or individual may introduce, release or discard alien species without approval. Don't think that the invasion of alien species has nothing to do with you
