R. S. (J. E. Williams et al. S. had the seeming distinction of causing the only “known” lamprey extinction. The Miller Lake lamprey, L. 1), the world’s smallest parasitic lamprey, was poisoned into apparent extinction in 1958 because it parasitized introduced trout at its only known locale, Miller Lake, Oregon (Bond and Kan 1973; R. R. Miller et al. 1989). Fortunately, a few remnant populations went unnoticed and were rediscovered in the region in 1992 and thereafter (Lorion et al. These populations occurred in headwaters of an adjoining river and a tributary to Miller Lake; the lake itself was not recolonized.

South African Cyprinids South Africa has an active conservation community that emphasizes the country’s unique biodiversity and biogeography. All 33 temperate freshwater species in South Africa are regional endemics, half occurring in a single river system (Skelton 2002). Cyprinids dominate, constituting 81% of the temperate species. Because of isolation, small average size, and a general lack of native piscivores, the fauna is 28 Part II. Imperiled Fishes inordinately at risk. Sixteen of the 27 cyprinids had IUCN (2004) CR, EN, or VU status.

Given such diversity, it is understandable that many species appear on national and international red data lists. The Congo blind barb, Caecobarbus geertsi, a cave-dwelling cyprinid from the lower Congo basin, is one of only two freshwater teleosts listed in Appendix II of CITES. IUCN (2004) listed 254 cyprinid species with international conservation status, the largest number among fish families.
