Invasive Nile Tilapia Discovered in Dalian Reservoir, Threatening Local Ecosystem
A group of large, black fish were spotted in the Dalian Xishan Reservoir by a local resident on May 6th, later confirmed to be the invasive Egyptian mouthbrooder species, which poses significant threats to the local water ecosystem due to its survival capabilities in polluted waters and potential to outcompete native species. The fish, which can grow up to one meter in length, were identified by experts from the Dalian Natural History Museum as Nile tilapia, a species native to the Nile River basin in Africa, known for its strong adaptability and high reproductive capabilities.
