Shenzhen Special Economic Zone News (reporter Wu Xuanling) Recently, some Shenzhen netizens said that they found scavenger fish in Xiangmi Lake and were worried that local fish would be infringed. The relevant departments immediately released a microblog saying that Shenzhen has not been affected at present, and reminded the public not to release scavenger fish.
According to Wang Bing, a visiting professor at the School of Life and Marine Sciences of Shenzhen University, the scientific name of the scavenger is catfish, and there are 50 genera of catfish in the family Catfish in the world, and most of the Chinese scavengers belong to the wild winged catfish and leopard winged catfish of the genus Winged Catfish, which are native to the Amazon River Basin in South America and were later introduced into China as ornamental fish. Aquarium enthusiasts mainly use it to remove algae that are attached to glass fish tanks, which is directly related to what is called scavenger. "Some aquarium enthusiasts later stopped keeping fish, so they were released into wild waters at will, because they could live in dirty water, use suction cup-shaped mouthparts to scrape the algae that epidid to the bottom pebbles, and have no natural enemies in the country, and now they inhabit small rivers, small ponds and ponds, becoming part of invasive organisms."
Shenzhen Municipal Water Bureau recently released a Microblog to remind the public that scavenger fish has strong viability, as an alien species has no natural enemies, but also will prey on the eggs of native fish, once released may lead to the difficulty of native fish to reproduce, until extinction, the local water ecology has a greater impact. At present, Shenzhen has not been affected, and the public should pay attention not to release scavenger fish.
