The fish in Doupeng Mountain

Four preliminary surveys or the fish resources in Doupeng Mountain were conducted from 1991 to 1992. 450 samples of fishes were collected, belonging to 4 orders, 9 families, 30 genera and 32 species. There are 3 species newly discovered in the Changjang River system. They are Hemimyzon macroptera, Parasilurus cochinennisis and Ctenogbius brunneus. The 32 species make up 15 61% of the total fish in Guizhou province. Among them there are 18 species of Cyprinidae, accounting for 56 25% of the total fish in Doupeng Mountain. Other 14 species are 3 of Cobitidae,4 of Homalopterdae, 2 of Serranidae, each one of bagridae, siluridae, Synbanchidae, Gobiidae and Channidae. Doupeng Mountain is abound in species of fish resources, but the quantity is now declining. The main reason for this is the bad way of killing fish used by toxicant or electricity.
