Abstract: Fish resources are important sources of income and protein to traditional inhabitants of coastal zones. In Garapuá village, the shellfish Lucina pectinata is the main resource exploited in mangroves. This study tests whether if in less explored areas (far from the village) L. pectinata individuals have higher densities and greater lengths, and if there was a decrease in cpue's over the last years. Samples were taken monthly in two habitats (mangrove channels and mangrove roots) in six mangrove areas by random squares. The results indicated that closer areas showed significantly lower densities than areas far from the village. Densities were significantly higher in mangrove roots (quizangas) than at channels. There was a significant increase in monthly L. pectinata cpue, from 18.2 dz./shellfish gatherers/day in 2001 to 19.3 in 2007, showing that this stock does not seem to be overexploited. However, (i) a long-term monitoring of Garapuá shellfish gatherers to evaluate if the stock will support an increasing pressure and (ii) several manipulative experiments to better understand ecological processes are suggested.
