Abstract in English:

ABSTRACT.- Mancini M., Rodriguez C., Prosperi C., Salinas V. & Bucco C. 2006. Main diseases of pejerrey (Odontesthes bonariensis) in central Argentina. Pesquisa Veterinária Brasileira 26(4):205-210. Facultad de Agronomía y Veterinaria. Universidad Nacional de Río Cuarto, Ruta Nac. 36 Km 601, Río Cuarto (5800) Córdoba, Argentina. E-mail: mmancini@ayv.unrc.edu.ar Argentina’s central region includes an important area covered by shallow pampean lakes and dams. In these environments, fishing of pejerrey Odontesthes bonariensis Valenciennes, 1835 (Pisces, Atherinopsidae), the most important fresh-water fish of the country, is a relevant social activity and also a considerable economic resource. The main diseases found in this species were studied from 1992 to 2003 in the provinces of Córdoba, La Rioja and Santa Fe (30° and 35° S, 61° and 67° W). Most cases were registered in high temperature months. Lernaea sp and Aeromonas hydrophila were the etiological agents most frequently found. The trophic characteristics of the aquatic environments enhanced disease processes and caused massive death of O. bonariensis, due to complex hydrochemical interactions.
