Abstract

The Local Ecological Knowledge of shellfish harvesters in a Northern Brazil estuary was recorded to provide socio-ecological information for the development of a co-management system. The research was carried out in the community of Acau, Paraiba state, from January to October 2015, and involved 120 shellfish harvesters (average age 44 years). Participant observations, interviews, questionnaires, free lists, and participatory mapping were used. Shellfishes were mostly collected by women as their main source of income. Most shellfish extraction sites were closest to the community and provided easy access to the resource. Twelve species of mollusks are collected, with Anomalocardia flexuosa being the most targeted species, with the highest Cognitive Salience Index—it stood out due to its relevance in terms of economic and cultural importance. The fishers stated that their main difficulties were transporting shellfish, health problems, low price and lack of buyers during winter. They would like to see the implementation of a fishery closure subsidized by unemployment insurance. We suggest that implementing management measures in conjunction with fishers’ input would be more effective than decisions based on scientific evidence alone.
