“…Eels have also been a large part of the freshwater animal biomass in a wide variety of freshwater habitats, including coastal estuaries, lakes, wetlands, rivers, mountain streams, and alpine tarns, and can penetrate large distances inland (McDowall 2011). Adult eels are often the top http://www.ecologyandsociety.org/vol21/iss2/art22/ predators in freshwater ecosystems and are opportunistic feeders consuming a diverse range of food, including stream insects, terrestrial insects, snails, freshwater crayfish, fish, and even small birds (Haro et al 2000, McDowall 2011, Jellyman 2012.

ABSTRACT. Indigenous peoples of North America, Australia, and New Zealand have a long tradition of harvesting freshwater animals. Over generations of reliance and subsistence harvesting, Indigenous peoples have acquired a profound understanding of these freshwater animals and ecosystems that have become embedded within their cultural identity. We have identified trans-Pacific parallels in the cultural significance of several freshwater animal groups, such as eels, other finfish, bivalves, and crayfish, to Indigenous peoples and their understanding and respect for the freshwater ecosystems on which their community survival depends. In recognizing such cultural connections, we found that non-Indigenous peoples can appreciate the deep significance of freshwater animals to Indigenous peoples and integrate Indigenous stewardship and Indigenous ecological knowledge into effective comanagement strategies for sustainable freshwater fisheries, such as Indigenous rangers, research partnerships, and Indigenous Protected Areas. Given that many of these culturally significant freshwater species also play key ecological roles in freshwater ecosystems, their recognition and prioritization in management and monitoring approaches should help sustain the health and well-being of both the social and ecological components of freshwater ecosystems.

ABSTRACT1. European eel (Anguilla anguilla) is recognized as a critically endangered species in the northern hemisphere. Threats such as overfishing or pollution are well known as risks for eel populations. However, much less is known about the impact of introduced fish on European eels. In particular, introduced large-bodied predators could become new predators to eels.2. The potential impact of European catfish (Silurus glanis L) on an eel population in the Camargue, southern France was studied using a combination of stable isotope and gut content analyses.3. Only large-bodied catfish (4500 mm) can consume numerous fish prey. However, catfish mostly consumed crayfish (Procambarus clarkii), these prey items being found in 79% of the guts of the largest individuals. Eel was absent from the dissected catfish guts. A mixing model based on Bayesian inference revealed that catfish diet included only 5% (0-8.5%) of marine sources (both eel and mullet).4. While local economic interests prompted ecological studies to assess whether catfish exerted a new and strong predatory pressure on eel, this study found that European catfish behaved as an opportunistic omnivore, and as such was not a direct threat as a predator on eel populations in the Camargue.
