Huangpu River Crocodile: It may be released!

Recently, some netizens posted, "The Mid -Autumn Festival went to the Huangpu River to take the crocodile. At that time, I did not expect to call the police, because the security guard at the ductive pier said that it had been there for a while, and the terrain could not climb ashore."

After that, there was a video shot. On the beach on the beach of the Huangpu River on the north of the port, a crocodile of seventy to eighty centimeters was basically in the sun. In response, Shanghai Port and Airlines public security responded that the netizens did have something to do and are still arrested this crocodile.

Regarding the origin of this crocodile, netizens have speculated, "If it is not for the crocodile, it means that either the farm sneaks away or someone is 'release'" "look like an Siamese crocodile. The farm escape or pets are released "" indicates that the Huangpu River ecology is getting better and better? "...

So what kind of variety is this? Relevant departments said that according to the online video materials, the crocodile was initially judged as an Siamese crocodile. In Shanghai, there is no natural distribution of crocodiles. The crocodile appeared in the Huangpu River, which was basically artificially discarded, released or escaped. The probability of release on the Internet is high, and it has nothing to do with the environment.

At present, the only types of local crocodiles in my country are preacher, and other crocodiles are foreign species. Siamese crocodile generally does not harm humans, but when they think they are attacked, they will also attack humans and affect social public safety. The Law Enforcement Corps of the Municipal Agricultural and Rural Commission will actively assist the public security department to carry out capture and disposal.

It is worth noting that, just last month, the same smelling crocodile crickets appeared in a river bang in Hongkou District. According to the residents, this crocodile can be released after a nearby shop was raised.

This is a freshwater giant carnivore native to North America, with sharp teeth and a "heavy armor". It predates Chinese species in my country, especially fish in the waters. The algae that is used as food will be flooded in large areas. Aquatic plants form a single species of advantages, which may lead to hypoxia and cause ecological disasters within a certain range. It is called "freshwater killer".

In this regard, relevant departments remind the public that unscientific and irregular releases will have a negative impact on the ecological environment. Especially in recent years, the spontaneous organizational activities of citizens and social groups have continued to increase, and the effects of some activities are counterproductive.

For example, some citizens release foreign species such as Brazilian turtles, bullfrogs, and Qingdaofu, which may break the original ecological balance of the local area. Taking Qingdao Fish as an example, their habits are to absorb algae, benthic animals, etc. If they reproduce a large amount in the wild, they may devour other fish eggs, and even cause the local native fish of the water system to extinct.又如，放生杂交种如锦鲤、异育银鲫等，可能造成自然水域鱼类基因混杂、本地种退化；放生凶猛鱼类如黑鱼、雀鳝等，可能破坏原有的生物链，影响其他The survival of fish.

In addition, the selected waters are not suitable for the survival, release time of release, the quality of the release, the quality of the seedlings that do not meet the requirements, and the unscientific release method, etc., will cause the death of the release fish. Affect urban landscape.
