This study focuses on the empirical knowledge and environmental perceptions of Uçá crab (Ucides
cordatus) fishermen from the Tamatateua region, municipality of Bragança, northeast of Pará. The
main objective is to describe the fishermen's traditional knowledge on this resource focusing on the
ecological knowledge from their perceptions and close relationship with the mangrove ecosystem.
used the qualitative research approach, in which the technique and the research instrument were
carried out using interviews from a questionnaire designed with semi-structured questions,
respectively. Data collection took place between 2017 and 2018, with 14 (fourteen) fishermen of Uçá
crab, aged between 22 and 62 years, in which the analytical process made use of content analysis. The
results demonstrate that the fishermen have elaborated ecological knowledge about the Uçá crab
specimen, as well as the natural and environmental phenomena. They perceive the connection between
the human being and the mangrove as a synonym of food, marketing, culture, religiosity, among
others, which, in some way, directly influence the knowledge passed on from generation to generation
through non-formal and informal education. It was also found that the management of the Uçá crab
resource is due to the learning process that occurs daily between kinship (father, son, grandson, uncles
and others), as well as in the process and socialization (sharing) between friends of the “ mangrove".
On the other hand, it was identified that even using predatory practices and arts, such as the hook, the
fishermen recognize them as such, but reveal the idea of maintaining the resource when arguing about
the respect in the reproduction periods of the specimen.
