The Southwestern Naturalist, 35(1):32-46 Mar-1990


" Between March and June 1986, we sampled fish at 22 stations on 17 streams in and adjacent to the newly established Sierra de Manantlán Biosphere Reserve, Jalisco and Colima, México. Our sampling included both mountain headwaters and lowland rivers in three separate Pacific Ocean drainages: Purificación, Marabasco, and Ayuquila-Armeria. We captured a total of 3,191 fish in 15 species (13 native) and 8 families; all but two of the stations contained fish. The most abundant and widespread species are in the families Goodeidae and Poeciliidae. Compared to other parts of North and Central America, the fish fauna of the Sierra de Manantlán is depauperate and has a high proportion of endemics. Diversion of streams for irrigation and unrestricted land use (agriculture, forestry, and mining) in stream watersheds threaten fish populations in and around the Sierra de Manantlán "
