English abstract The Mamanguape estuary, located in the Paraíba State (Brazil), hosts many traditional fishing communities and Amerindian villages whose use of the regional natural resources is fundamental to their cultural and physical survival. The aim was to register the traditional local knowledge about the different fish techniques, the influence of the dynamics of the natural environment on the activities of the blue land crab, and the relationships between the sizes of their dens and the sizes of the animals themselves. The only technique used to capture blue land crab is a trap called ‘mousetrap’. It was recorded different materials such as PET bottles, to build the traps. The fishermen stated that fruits are used as bait as well as sugar-cane and onions. The phases of the moon and the different tides do not significantly influence their activities as the crabs inhabit higher lands beyond the influence of normal tides. The knowledge documented here concerning the blue land crab demonstrated that these shell fish harvesters have a detailed understanding of their environment based on observations and empiricism that allows them to determine which techniques and strategies will increase their chances of capturing their prey and consequently guaranteeing their income
Portuguese abstract O estuário do Rio Mamanguape, localizado no Estado da Paraíba (Brasil), é residência de diversas comunidades de pescadores tradicionais e povos indígenas que dependem dos recursos naturais para a sobrevivência física e cultural. O objetivo foi registrar o conhecimento tradicional local sobre as diferentes técnicas de captura do goiamum, a influência dos diferentes fatores ambientais sobre a atividade de captura, e outros fatores diversos como diferença entre machos e fêmeas e o tamanho das tocas. A técnica utilizada que permite a captura é a ratoeira, construída com diferentes materiais. As iscas são frutas, cana-de-açúcar ou cebola. As fases da lua não influenciam diretamente a atividade, já que o goiamum habita áreas acima da preamar. O conhecimento dos catadores registrado neste trabalho mostra um entendimento detalhado do ambiente e do animal, construído em empiricismo e observações, que permite determinar a melhor estratégia e técnica para aumentar o sucesso de captura do goiamum, consequentemente garantindo a renda familiar
