Sustainability Analysis of the Benthic Fisheries Managed in the TURF System in Chile

Overview
Territorial use rights in fisheries (TURF) are considered to aid to the sustainability of small-scale fisheries, because they remove the perverse incentives, which sustain the tragedy of the commons. Nevertheless, a comprehensive evaluation of the implementation of TURFs is lacking. Chile offers a unique opportunity, because an extensive system for benthic fisheries has been implemented, with at present hundreds of TURFs along the coast. This study analyzes the sustainability of all the TURFs (109) along a stretch of 800 Km of coast, using population, productive, economic, social and institutional indicators. The information was obtained from the technical reports and monitoring each TURF has to prepare for the authority each year, databases the authority has and interviews with artisanal fishermen. Three states of TURFs were identified: unsustainable, poorly sustainable and sustainable. The resources exploited in the analyzed TURFs are the chilean abalon or “loco” (Concholepas concholepas), the key hole limpets “lapa negra” (Fissurella latimarginata), and “lapa rosada” (Fissurella cumingi), the kelps “huiro negro” (Lessonia berteroana), and “huiro palo” (Lessonia trabeculata), the surf clam “Macha” (Mesodesma donacium), the scallop “ostión del norte” (Argopecten purpuratus) and the seaurchin “erizo rojo” (Loxechinus albus). Results show general low performance for population, production and economic indicators, but good performance for social and institutional indicators. Overall the system shows a poor sustainability, which principally means unstable populations, landings and income in most of the TURFs. This result, which differs from most published analyses of the system, is explained mainly by the impossibility to reach a stable fishery through management of so small areas, given the natural variability of the species and the general environment. The good performance of some TURFs cannot be explained by a single factor, which is consistent with the complexity of the system, which makes it little amenable for proper management.
