Several ecological and climatic factors, especially those related to human activities, have been contributing to the disappearance of natural populations of piracanjuba ( Brycon orbignyanus ). Due to the importance of these fi sh to the ecosystems in which they are located and their qualities of fast growth and ability to adapt to controlled environments, producers have expressed increased interest in recent years in using this species, with particular aims of increasing production, and participation in conservation programs. In this study, strategies for the sustainable management of B. orbignyanus are idealized and discussed, with the goals of perfecting the reproductive, genetic, environmental and sanitary management of this species and suggestions for improving monitoring stocks maintained in captivity and natural populations. These strategies can be used as models for other migratory species threatened with extinction. Diversos factores ecologicos y climaticos y especialmente aquellos relacionados con acciones humanas, han llevado a la desaparicion de poblaciones naturales de piracanjuba ( Brycon orbignyanus ). Por la importancia en los ecosistemas en los cuales esta ubicada y por sus cualidades de crecimiento rapido y adecuada adaptacion a ambientes controlados, en los ultimos anos el interes de los productores en la utilizacion de esa especie ha aumentado, con el objetivo de la produccion, la mejora economica y la participacion en programas de conservacion. Con el objetivo de perfeccionar el manejo e monitoreo reproductivo, genetico, ambiental y de sanidad de lotes mantenidos en cautiverio y de poblaciones naturales de B. orbignyanus, estrategias de manejo sustentable de esa especie son idealizados y discutidos, pudiendo ser usados como modelo para otras especies migratorias amenazadas de extincion.
