Scale, connectivity, and incentives in the introduction and management of non‐native species: the case of exotic salmonids in Patagonia

Abstract: Many introduced species have become established throughout large areas of the world, causing millions of dollars in damages. The introduction of such pest species is universally condemned, and science and management efforts are geared toward eradication, containment, or prevention of future infestations. Meanwhile, other organisms are actively traded around the world for consumption, as well as recreational and aesthetic purposes, providing examples of the conflict between human development and conservation.

“…These regions similarly experience very high precipitation and levels of sedimentation (Silva and Prego 2002;Nuwer and Keil 2005;Sepú lveda et al 2009), although to the best of our knowledge similar studies of OM flux through infaunal communities have not been conducted to date. Such knowledge would be particularly relevant given the exploitation of higher trophic level species in these regions that are likely supported by such macroinfaunal communities, and potential changes to sediment chemistry caused by the dramatic increase in aquaculture developments in the Chilean fjords (Pascual et al 2009). …”

“…Among freshwater introductions, salmonids are considered to be among the most pervasive exotic species in the world (Pascual et al 2009). In Chile, the environmental concerns from salmonid escapes have focused on shortterm predatory effects upon native fish, long-term effects linked to the probability of farmed salmon establishing self-sustainable populations, and disease and pathogen transfer (Young et al 2010, Arismendi et al 2012, Niklitschek et al 2013).…”

“…Therefore, the case of South America might be considered as a shifting baseline in the form of generational amnesia, where knowledge extinction occurs because younger generations are not aware of past biological conditions (Papworth et al 2009). Moreover, non-native species are often much valued and protected by local people, in part, because they represent an income (Pascual et al 2009;Lambertucci and Speziale 2011). They are hunted or fished, restaurants advertise them as traditional dishes, and souvenir shops sell souvenirs with their likeness represented (Fig.…”
