    The main reasons why piranhas are not rampant in China are as follows:

    1.Biological habits: Piranhas live mainly in the Amazon River basin in South America, where they have specific requirements for water temperature, water quality, and food. In China, due to the different climatic conditions and ecological environment, piranhas cannot survive and reproduce.

    2.Ecological environment: The climate of China is quite different from that of South America, which makes it difficult for piranhas to adapt to the living conditions in China. In addition, many of China's rivers, lakes, and marine ecosystems do not have native populations of piranhas, which prevents them from flooding in China.

    3.Human activities: Since piranhas have specific water temperature requirements, human activities such as the construction of hydropower stations and changes in river channels may affect the living environment of piranhas, thus limiting their spread.

    4.Entry restrictions: China has strict regulations on the import and export of animals and plants to prevent the invasion of pests. If piranhas attempt to enter China through illegal means, they will be investigated and intercepted by customs.

    5.Citizenship: The public in China has a high level of awareness about biological protection and will immediately report illegal releases of piranhas, which can also help prevent the proliferation of piranhas.

    In summary, due to many reasons such as biological habits, ecological environment, human activities, entry restrictions and civic awareness, piranhas cannot be rampant in China.

    Piranha in China: Invasive species, causing local ecological damage.

    Piranhas were first introduced to China as ornamental fish. Their gorgeous appearance, especially their resounding reputation, are attractive to some fish lovers with a curious mind. Piranhas in natural water bodies are almost always pets or commodities abandoned by owners and traders.

    As a tropical fish, piranhas have rigid requirements for water temperature. The climate of the southern part of our country, especially the Liangguang region, is similar to that of its place of origin, which makes it possible for piranhas to survive. Piranhas are highly reproductive, and can lay hundreds or even thousands of eggs at a time.

    It is known that they lack natural predators in China, and once they reproduce in large numbers, it is very likely to deal a heavy blow to China's national security, water biodiversity and fishery production in Qingyuan.

    In fact, the name "piranha" does not refer to a specific type of fish, but is a general term for freshwater fish with carnivorous habits that live in the tropical regions of South America and the Amazon River basin. In the local indigenous dialect, this type of fish is called piranha, which means "fish with teeth". In China, people often refer to these fish as piranas and man-eating pomfrets.
