In March, Wuhan residents released 40 trucks of fish to the Yangtze River at a time.

Brazilian tortoise, Russian Sturgeon, scavenger fish. Fish species that used to belong to foreign countries can now be salvaged in the Yangtze River, and even the freshwater white Pomfret, which is closely related to the piranha, has been salvaged in the Wuhan section of the Yangtze River.

Changbaojun also learned that the most amazing one was that in March this year, Wuhan citizens organized 40 trucks of fish to be released into the river.

"releasing raw fish fry is as important to me as eating." This is what a loving citizen in Wuhan said who volunteered to help set free.

But is the kindness of citizens good for the ecology of the Yangtze River?

Maybe he did something bad with good intentions.

"the commercial fish they buy in the market will not only be difficult to survive in the Yangtze River, but will also cause damage to the original species of the Yangtze River and affect the purity of the species." The person in charge of Wuhan Agricultural Comprehensive Law Enforcement Supervision Brigade told Changbaojun that loving release must be truly effective in order to be meaningful, otherwise it would be good intentions to do bad things.

On the 22nd, at the scene of the 2016 multiplication and release event in Wuhan, Changbaojun learned from the Wuhan Agricultural Comprehensive Law Enforcement Supervision Brigade that many citizens have been released blindly in recent years, causing damage to the aquatic resources of the Yangtze River to a certain extent.

Dozens of "foreign fish" appear in the Yangtze River.

Law enforcement officials are cracking down on ecstasy placed by fishermen

Not long ago, in a campaign to crack down on illegal fishing, the Wuhan Comprehensive Agricultural Law Enforcement Supervision Brigade found Brazilian turtles in the "ecstasy" placed by fishermen.

Brazilian tortoise, crocodile tortoise, longevity snail, freshwater white Pomfret, leatherbeard catfish, Russian Sturgeon, spoon-nosed Sturgeon, hybrid Sturgeon, African crucian carp, these fish species that do not exist in the Yangtze River fish resources, in recent years, personnel of the comprehensive agricultural law enforcement inspection brigade have fished from the Yangtze River in the process of law enforcement.

Brazilian turtles caught from the Yangtze River

"Brazilian turtles find the most. The year before last, the citizens caught the scavenger fish in the Han River. " According to the army, the scavenger fish is known as the 'killer of freshwater fish' because it has no natural enemies in China and grows savagely, so it will devour the eggs of other fish, causing great damage to the original species of the Yangtze River. Gehu catfish has also been found in the Yangtze River, which is so lethal to green shrimp that fishermen report that shrimp can no longer be caught in the Yangtze River.

Freshwater Pomfret data map source network

In September 2014, fishermen caught freshwater Pomfret near Yangluo Power Plant. Freshwater Pomfret is a tropical fish species, which has a living space because the water temperature of the waste water discharged from Yangluo Power Plant is too high. The freshwater Pomfret is closely related to the so-called "piranha". It has many sharp teeth in its mouth and is aggressive to people.

Thousands of caring groups in Wuhan buy fish and release them every week.

At the scene of multiplication and release, Changbao Jun saw several loving citizens who volunteered to help release. They said that they knew that there was a proliferation and release activity today, so they made an appointment in the WeChat group to volunteer to help release.

Mr. Wang, 47, is the leader of the WeChat group, with more than 190 Wechat members. He told reporters that he had been engaged in the release of fish fry for more than three years and would organize a release activity once a week. "releasing raw fish fry is as important to me as eating."

He said that every week, donations will be organized in the group, and then go to the South China Seafood Market and Baishazhou Market to buy fish, and then put them into the Yangtze River.

It is understood that there are about a thousand caring groups like this in Wuhan. In March this year, 40 truckloads of fish were organized to be released into the river.

"the commercial fish they buy in the market will not only be difficult to survive in the Yangtze River, but will also cause damage to the original species of the Yangtze River and affect the purity of the species." Xiang Jun told reporters that loving release must be truly effective in order to be meaningful, otherwise it is good intentions to do bad things.

Release should also be carried out in accordance with regulations and released scientifically.

Law enforcement officers are releasing carmine fish.

"at present, there are no statistics on the number of invasive exotic fish species, but the trend is increasing." The city's comprehensive agricultural law enforcement inspector brigade said that the release of citizens is mostly personal behavior, there is no fixed place, there are two rivers and four banks, often take advantage of people unprepared, can only be dissuaded. "

In the regulations on the Administration of Proliferation and release of Aquatic organisms in China, it is forbidden to use alien species, hybrids, transgenic species and other aquatic species that do not meet the ecological requirements for proliferation and release. Units and individuals that carry out large-scale activities of proliferation and release of aquatic organisms on their own shall report to the local fishery administrative department 15 days in advance on the types, quantity, specifications, time and place of proliferation and release, and accept supervision and inspection.

For how to release scientifically, the municipal agricultural comprehensive law enforcement supervision brigade also gave reasonable suggestions.

01

First of all, to choose the fish of the original seed generation of the Yangtze River, members of the public can go to professional original fishing grounds to buy fish fry. The fry in the original fishing grounds have been quarantined, pregnant and up to a certain standard. This kind of fish fry has a high survival rate and can effectively achieve the purpose of release. In addition, the brigade also suggested that four major domestic fish, green, grass, silver carp and bighead carp, should be selected during release, and exotic species are prohibited.

"you can't release animals blindly," he said. "protected animals should be released in national and provincial protected areas in order to achieve the goal of release. We can install electronic chips for releasing precious fish species to understand the dynamics of releasing fish species in real time. " Xiang Jun, head of the municipal comprehensive agricultural law enforcement supervision brigade, said that if citizens are willing to do good, they can contact the original seed farm through the municipal agricultural comprehensive law enforcement supervision brigade to purchase the correct release species, or participate in artificial multiplication and release activities. In peacetime, if members of the public find strange species, please report to the city agricultural comprehensive law enforcement inspector brigade in time.

Changbaojun learned that the Wuhan Agricultural Comprehensive Law Enforcement Corps intends to provide a special release area at the newly built wharf on the Hankou beach to guide everyone to release scientifically.
