The fishery handmade in the estuary-mangrove complex is the main protein source and cost of many coastal communities, which acquired and accumulated knowledge over generations, the fruit esxperience. Studies about knowledge of the local people about nature and how natural resources are exploited are so important for the enhancement of ethnobiological knowledge the same and the management of natural resources appropriately. Aiming to analyze the ethnobiological knowledge the fishers of estuary mangrove Vaza-Barris, Sergipe have about the swimming crabs and descrive the activity of catching this feature, there were 20 semi-structured and structured interviews, participant observations and informal conversations with experts fishers in the São Cristóvão city. The specific folk were identified by: "siri-de-mangue" (Callinectes exasperatus), "siri-de-ponta", "siria-de-cumidia" and "siria-nica" (Callinectes danae), "siri-pimenta" and "siri-cachorro" (Callinectes larvatus), "siri-cagão" (Callinectes bocourti), "siri-patola" (Calappa sulcata" and "siri-de-viveiro" (Callinectes sapidus and Callinectes bocourti). Morphological, ecological and behavioral criteria were used in the identification, naming and classification of specific folk. Fishers associate the happening, spatial and temporal distribution and reproductive aspectes of crabs to tidal movemente, lunar cycle and the seasons. The trophic ecology of crabs is known by fishers, featuring many correspondences with scientific information and the process of molting crabs is know in detail. Knowledge of this feature were acquired through cultural transmission (vertically and horizontally), beyond individual leraning afforded by practical experience (fishing). The techniques used to catch the crabs are the traps, line, gaff, knife, torch and fishnet. The fishery regime and the choice of the techinque vary in relation to the target species, the movement of the tide, the lunar cycle and the seasonal period and, consequently, in relation to the distribution patterns of the species of crabs. Women use the line in catching the crabs, which is known as "woman's fishery". The "siri-de-mangue" is sold alive and "siri-de-ponta" undergo a processing, which are cooked and broken retained for the flesh. The monthly income just by selling crabs varies from R$150 to R$ 1000 depending on the species of crab which is marketed, of the seasonal period and the presence of the illegal seller in the marketing process. It is necessary to researches, starting from the information of the fishers, to test hypotheses, and enrich the scientific knowledge about species of crabs, particularly on C. exasperatus, which is the most important cultural and economic species.
