ERADICATION OF SPOTTED JEWELFISH, HEMICHROMIS GUTTATUS, FROM POZA SAN JOSÉ DEL ANTEOJO, CUATRO CIÉNEGAS BOLSÓN, COAHUILA, MEXICO

Abstract We report an apparently successful effort to restore native fishes to a pool in the Cuatro Cienegas Bolson, Coahuila, Mexico. The results demonstrate the feasibility, in small, confined systems, of eliminating a recently introduced nonnative fish, the spotted jewelfish (Hemichromis guttatus), and transplanting a native fish assemblage from nearby areas. We recommend that similar removal and restoration activities be conducted to protect the unique, highly endemic Cuatro Cienegas fish fauna.
