Resumen:
The list of “most wanted” aquatic alien species is dominated by accidentally introduced organisms that have already taken over large areas of the world, producing millions of dollars in damages. Naturally, the introduction of such pest species is condemned without a trial, and science and management efforts are geared towards elimination, containment, and prevention of future infestations. Meanwhile, an alternative list of aquatic organisms is actively traded around the World, for food, fun, or aesthetic reasons. The introduction of such commercial species divides the waters, providing text book examples of the conflicts between human development and nature conservation, and straining the limits of sustainable development. Questions arise: Are there win-win situations to be found between production and the integrity of nature? How can science and management promote such win-win situations?   In this conference I attempt to provide some answers to those questions by analyzing three case studies of exotic Salmonids in Patagonia: trout aquaculture in shallow fishless lakes, trout recreational fisheries in lakes and rivers, and marine net pen salmon aquaculture. For each case study, I will review our current state of knowledge, identifying major uncertainties. I will also analyze the positive and negative impacts brought about by exotic Salmonids, discussing the prospects for finding win-win situations. In the end, I will propose that three interrelated properties of these case studies, scale, connectivity, and incentives for conservation, determine our ability to identify and promote such win-win situations. I will present my views on how science and management can help to promote such situations.
