Resumen
Illegal fishing poses a major threat for the conservation of marine resources worldwide. However,
there is still limited empirical research that quantifies illegal catch levels. This study uses the
Randomized Response Technique to estimate the proportion of divers, and the quantities extracted of
illegal "loco" (Concholepas concholepas, an endemic gastropod) managed through a Territorial User
Rights for Fisheries system (TURFs) in Chile. Results show that illegal fishing is widespread along the
TURFs system, with official reported landings accounting for only 14- 31% of the total loco extraction.
Quantitative estimates suggest that ignoring the magnitude of illegal fishing and only considering
official landings statistics can conduct to serious misleading conclusions about the status and trends
of a TURFs managed fishery. We found evidence of unions authorizing their members to poach inside
TURFs, highlighting the need to design TURFs system in a way that government and fishers"
incentives and objectives are continually adapting to be in line and not at odds. In the same way,
government support for enforcement is key for the TURFs system to secure the rights that are in place.
This study provides insights on how to improve governance of TURFs in Chile and around the world. FONDECYT FONDECYT
