Experts say that it is harmful, and it is recommended to be included in key management

Gu Dang En is a scientist of invasion and control positions of foreign species in the national large freshwater fish industry technology system. The research direction is that fish intrusion ecology. He pays more attention to crocodile crickets.

On August 24th, Gu Dang En told Jimu Journalists that the largest can be more than 200 pounds of crocodile crickets, and there have been records in China that have been caught by ninety pounds of crocodile crickets. The crocodile can be killed in the natural waters. In the case of insufficient food, even the same type is disabled. Under normal circumstances, crocodiles will not actively attack people, but they do not rule out extreme situations. In addition, crocodile tubes are not suitable for consumption, and the eggs are poisonous, which is almost a high -risk foreign aquatic creature that is almost harmful and has no benefit. He recommends that it will be included in the national key management invasion of species.

Gu Dangen introduced that the crocodile bird's body was weird and fierce, and it was in line with the psychology of people's curiosity. Therefore, it was introduced as an ornamental fish breeding object to my country for breeding. Because its growth rate is too fast, it is artificially released or discarded by the aquarium tank that cannot be accommodated or unable to bear the cost of breeding. Therefore, there are often wild individuals in lakes and river channels in some urban areas. The crocodile crickets grow fast and the fertility is amazing. It can reach sexual maturity in three years under breeding conditions. The crocodile crickets can overwinter and reach sexual maturity in many areas of southern my country. Once the consequences of natural population are established, it will be unimaginable.

The important object of predation in the water is local fish, which may cause the original food chain of the waters to the water chain. Broken chain. "If a large number of local fish prey on crocodiles, it may lead to a large number of algae breeding, which will bring a series of serious consequences to the water ecosystem, such as water stench." Li Chang said.

For whether the crocodile crickets that netizens care about can be eaten, Li Changshi said that crocodile crickets are a large kind of carnivorous freshwater fish. What impact will it affect the human body. "Eating is not the best way to solve the problem. I suggest that you send it to the aquarium after the arrest. As a negative textbook for everyone, let everyone know foreign invasion species, popularize its harm to natural water bodies, which will attract people's attention." Li Chang watched it. It is said that after catching the crocodile, it can also be sent to the zoo as a meal for carnivorous animals, or buried for harmless treatment.
