Resumen: "This work reports on how bene?ts are distributed among the owners of ?shing grounds in the spiny lobster (Panulirus argus) ?shery of Punta Allen, Mexico. This MSC certi?ed (2012) small-scale ?shery, has been comanaged as a Territorial Use Rights Fishery (TURF) since 1969. Members of the local ?shing cooperative, have exclusive access to individual ?shing grounds. The ?shery is based on the use of arti?cial shelters. These bottom devices provide refuges for lobsters, reduce predation mortality, and facilitate harvesting by free diving and the use of hand nets. Data from the ?shing cooperative logbooks were used to calculate ?shing incomes indicators per ?sher (revenues, quasi-pro?ts of the variable costs, pro?ts, and resource rent) achieved in seven lobster ?shing seasons (2007–2014). Distributions statistics (shape parameters and log transformations), and inequality metrics (Lorenz curve and Gini index G) were applied to the income indicators. The analysis was complemented with a ?shers’ perceptions survey about the e?ectiveness of joint Government and cooperative regulations. The G index of the ?shing revenues distributions showedlow values (0.387 ± 0.017) anda stable trend inthe seven lobsterseasons analyzed.Thecalculated Gvaluesofthe ?shingincomeindicatorsincreasedfrom0.387to0.490.
