Factores que afectan la distribución de salmónidos en Argentina

The introductions of salmonids in Argentina can be considered as successfull. The have become established as reproducing populations in southern and middle-western lakes and reservoirs. An extensive sampling programme on 112 lakes and reservoirs was carried out during the summers of 1984 to 1987. Environmental features that determine their present distribution were analyzed. The hypothesis, which we used as starting-point, is that it has been attempted to introduce at least once and least one species of salmonids in all lakes and reservoirs of Argentina.
