Estudo preliminar da caracterização sócioeconómica da pesca do caranguejo de mangal (Scylla serrata Forskal 1755) no estuário dos Bons Sinais em Quelimane

Abstract

This preliminary study on the socioeconomic characterization of Scylla serrata fishing in the Good Signs estuary was carried out with the main objective of assessing the contribution of this activity to improving the social and economic prospects of fishermen's families. Data collection was done for two (2) months (August and September). The sampling techniques used for information gathering were observation and semi-structured interviews with fishermen in the affected communities (Inhangulue, Carungo and Mucupia) along of Bons sinais Estuary. Observation was used to characterize fishing activity and thus consisted of understanding the type of fishing gear used, the age group of fishermen. Catches were estimated based on the sum of the average quantities caught daily by each fisherman; fishing effort was assumed to be a standard 7 fishing days / week by most; On the other hand, the socioeconomic profile of fishermen based on acquired goods categorized by groups as indicators of the development of social and economic perspectives was also analyzed. Observations made during the collection of information found that excavation and hook fishing are the main fishing gear operating in a resource-oriented manner. The activity is performed by fishermen of all age groups, but with greater expressiveness for adolescents and young people. The estimated daily average catch is 3.5kg / day per fisherman, and with an average daily yield of over 400.00 Mts. Estimates of monthly catches are in the order of approximately 100 kg and an estimated income of approximately 12000,00Mt. On the other hand, the results show that most fishermen (59%) rely solely on this activity for income to meet their needs within their families. The defined socio-economic indicators show a low contribution of this activity to the growth of the social and economic prospects of fishermen's families. Due to the opening of more channels of demand and demand for the resource, it is noticeable the tendency of increasing supply by the communities.
