Resumen:
The expression of anadromy in fishes triggers profound changes in growth, maturation and survival, with important consequences for the adaptation to new environments, for population dynamics, and the interaction with receiving communities. Within this general view, our research program looks at exotic anadromous salmonids from three different, albeit complementary perspectives: a) as a natural experiment in adaptation and microevolution, b) as agents of ecological impacts, and c) as valuable commercial and recreational species. In this presentation we review our past research and present our main results. We emphasize those studies in which we included the use of molecular techniques and approaches. We then analyze what we consider to be the most critical management questions regarding exotic salmon in Patagonia, and outline our research plan for coming years.
