Pesca artesanal e morfometria do siri-vermelho Callinectes bocourti A. Milne-Edwards, 1879 [in A. Milne-Edwards, 1873-1880] em um estuário amazônico.

Abstract

Crustaceans compose the groups of fishing resources that stand out most in mangrove habitats and that generate a source of food and income for artisanal fishermen from different Brazilian regions. Thus, the objective was to characterize the socioeconomic and structural aspects of swimming crab fishing performed in São Caetano de Odivelas city - Pará. For this purpose, monitoring was carried out in swimming crab fisheries, as well as interviews with fishermen in two periods (February to May 2014 and August 2019), using semi-structured questionnaires taking into account the snowball sampling method. With the data obtained, a descriptive analysis was performed, CPUE was calculated, as well as the data correlations. In addition, the weight-length ratio of “juveniles and adults specimens was compared. All fishermen interviewed were men (between 19 and 73 years old), they come from the region and have been fishing since childhood. They have basic education, receive government benefits (fishing ban insurance and family allowance). The results indicate that the soft-shell crab fishing is carried out in small boats, made by the fishermen themselves. During fishing, a selection process is carried out, with only large males are sold. It was also found that the "small" swimming crab has a proportional weight greater in relation to their length than the "larger". Crab fishing in São Caetano de Odivelas is similar and with the same peculiarities as the next estuaries. In addition, fishermen demonstrate experience in the activity in terms of knowledge about the morphology, reproduction, habitat of the species, period of abundance and tidal dynamics and the relationship of this fishing resource with the abiotic factors of the mangrove ecosystem. Fishermen understand the importance of continuing fishing activity as well as the environment in which they live and reproduce.
