Fishing for resilience

Management approaches that focus on social–ecological systems—systems comprised of ecosystems, landscapes, and humans—are needed to secure the sustainability of inland recreational fisheries without jeopardizing the integrity of the underlying social and ecological components. Resilience management can be useful because it focuses on providing recreational capacity for fishermen under a variety of conditions while assuring that the social–ecological system is not pushed to a critical threshold that would result in a new, undesired system regime. Resilience management is based on a system perspective that accounts for the possible regimes a system could manifest. It aims to enhance system properties that allow continued maintenance of the system in a desired regime in which multiple goods and services, including recreational capacity, are provided. In this forum paper, we provide an overview of the potential of a resilience approach to the management of recreational fisheries and highlight the scientific and administrative challenges to its successful implementation.

Saliendo del circulo vicioso: Gestiones alternativas para garantizar la sostenibilidad de la pesca

The management of fisheries has historically focused on maintaining maximum sustained yields of single species. This approach generally ignored the broader social-ecological context that consists of coupled systems of people and nature, and resulted in the overexploitation of many fisheries globally, including many in Latin America. There are severe negative repercussion of overfishing, on both ecosystems and humans that rely on food and income provided by fisheries. Traditional management schemes based on maximizing should be replaced with approaches that explicitly recognize the coupling of social and ecological systems. We suggest a resilience approach that focuses on tradeoffs as a means of guaranteeing outputs over a broad range of conditions and avoiding undesirable thresholds. Resilience approaches may on average produce lower annual yields, but are more likely to allow the continued provision of multiple goods and services. A resilience approach requires scientifically derived data and consistent monitoring, and will not be successful if feedbacks between ecosystems and humans are ignored. The words "Fisheries" and "Sustainability" do not comprise an oxymoron but a logical partnership in resilience management. People and institutions engaged in Latin-American fisheries management have an opportunity to lead in the development of sustainable fisheries management with a resilience-based approach. Here we describe such an approach, and the steps necessary to ensure success.
