The Para State, which coast limits from Cabo do Norte to Gurupi, is the most important fishing state in North of Brazil. According the economic importance, of the Acoupa weakfish Cynoscion acoupa and Spanish mackerel Scomberomorus brasiliensis are main species, captured mostly in Augusto Corrêa, Bragança, Curuçá, São Caetano de Odivelas, São João de Pirabas and Vigia towns. This study aim to describe the fishing systems of these towns in an approam social, technological, economic and ecological, in order to establishi policy tools, that support the development of a management plan for the sustainability of these fisheries. To describe the fishery systems, 45 attributes, were considered in a categorical scale or percentages, classified according the established dimensions. A ´study case´, aiming to better describe the fishing systems, was analised in Bragança. To identify groups and similarities betweem fishery systems and town. Multivariate analysis were applied this analysis reported two distinct groups of fishery systems. When analyzed by dimension, the fishery systems were similar for both social and ecological dimensions. In relation to technological and economical dimensions, was concluded that Bragança and Vigia (Acoupa weakfish system) were different specially by the boats operates, net size, production and profits. The spanish mackerel system, it was compore by a float of small boats (´Barcos de Pequeno Porte´). The case study showed that, although the low importance in acoupa weakfish commercialization are rather important, with a high commercialization value, the value of the meat is responsible for most of the profit. The Spanish mackerel case study reported that the fishery in Bragança ocorrin three different regions: coast Amapá, coast Salinas and coast Bragança. According these a management plan, based in a social dimension, must include actions that favors citizenship, health, education, job and qualification. In relation to the ecological dimension, considering that both fishery were stocks exploited at the maximum level, management measures must be implemented. Finally, with regard to technological and economic aspects, it was observed that in Bragança and in Vigia, the acoupa weakfish fishing systems were "sustainable". The increase in catches with a decreasing trend in the production should be considered be carefull specially whem new financings are to be released to the fisherman.
