Resumen:
Several accidentally introduced species have taken over large areas of the world, producing millions of dollars in damages. The introduction of such pest species is universally condemned, while science and management efforts are geared towards eradication, containment, or prevention of future infestations. Meanwhile, another list of organisms is actively traded around the world, for food, fun, or aesthetic reasons, providing examples of the conflict between human development and conservation. When dealing with such species, are there ways to balance the competing goals of economic production and protection of nature? How can science help to identify suitable compromises? We attempt to answer these questions by analyzing three case studies dealing with exotic salmonids in Patagonia: trout aquaculture in shallow fishless lakes, trout recreational fisheries, and marine net pen salmon aquaculture. We propose that three interrelated properties of these case studies, scale, connectivity, and incentives for conservation, determine opportunities to reverse damaging situations and our ability to identify and promote situations that balance production and the integrity of nature.
