Abstract: Based on field surveys between 2002 and 2010, and fish collections in the National Zoological Museum, Institute of Zoology, Chinese Academy of Sciences, a total of 93 wild fish species including 12 introduced species had been recorded in Beijing and adjacent areas. Eighty five of these species, including some migratory and estuarine fishes, are native to the region. Only 43 native wild species were collected in our field work from 2002 to 2010. Compared with the historical records, nearly 50% of native fish species may have extirpated during the last over 30 years. Major reasons for these losses may include continuous natural drought, anthropogenic water use, aquatic environmental changes associated with rapid city expansion and overpopulation, and overexploitation of wild fish. In order to recover and ensure sustainable use of regional wild fish resources, measures such as systematic and thorough investigation of fish resources, enhanced management of aquatic protected areas, construction of a fish germplasm bank, and legislation on local protection of species are urgently needed.
