O Estado do Par?, cujo litoral se estende do Cabo do Norte ? foz do rio Gurupi, representa o principal p?lo pesqueiro da regi?o. Dentre as esp?cies de import?ncia econ?mica no estado, destaca-se a pescada amarela Cynoscion acoupa e serra Scomberomorus brasiliensis, capturadas principalmente nos munic?pios de Augusto Corr?a, Bragan?a, Curu??, S?o Caetano de Odivelas, S?o Jo?o de Pirabas e Vigia. Este trabalho teve o objetivo de descrever estes sistemas pesqueiros segundo as dimens?es sociais, tecnol?gicas, econ?micas e ecol?gicos visando estabelecer linhas de a??o que auxiliem na estrutura??o de um plano de manejo que garanta a sustentabilidade das pescarias. Para descrever os sistemas de pesca, uma lista de 45 atributos, na forma de valores num?ricos absolutos ou porcentagens, classificados de acordo com cada dimens?o supracitada. Um estudo mais aprofundado (Estudo de Caso) foi efetuado em Bragan?a, para ambos sistemas. An?lise multivariada de agrupamento e ordena??o (MDS), comparando os sistemas pesqueiros e considerando os diferentes munic?pios, foram aplicadas, visando identificar os agrupamentos e as poss?veis causas da semelhan?a entre os sistemas de pesca por munic?pio. A an?lise dos sistemas da pescada amarela e serra juntas, mostraram a forma??o de dois grupos. Quando analisados por dimens?o separadamente, registrou-se similaridade entre ambos os sistemas nas dimens?es social e ecol?gica. Com rela??o ?s dimens?es tecnol?gica e econ?mica notou-se que os munic?pios de Bragan?a e Vigia (sistema pescada amarela) destacaram-se, sobretudo pelas embarca??es utilizadas, tamanho das redes de pesca, produ??o por pescaria e lucro l?quido obtido nas pescarias. Para a serra registrou-se, entre os munic?pios do sistema, a predomin?ncia de barcos de pequeno porte nas capturas. O estudo de caso em Bragan?a indicou que apesar da import?ncia do grude (bexiga natat?ria) na cadeia de comercializa??o da pescada amarela, com elevado valor de comercializa??o, a venda da carne constituiu a principal fonte de lucro l?quido. O estudo de caso da serra revelou que as suas pescarias em Bragan?a ocorreram em tr?s ?reas distintas: costa do Amap?, costa de Salinas e costa de Bragan?a. Considerando o exposto, pressup?e-se que um plano de manejo no ?mbito social deve prover a??es em prol da cidadania, sa?de, educa??o, emprego e capacita??o. Numa abordagem ecol?gica, considerando que ambos os estoques se encontram no limite m?ximo sustent?vel, medidas de manejo devem ser implementadas. Finalmente, com rela??o aos aspectos tecnol?gicos e econ?micos observou-se que as pescarias em Bragan?a e Vigia foram visualmente ?sustent?veis?. Entretanto, os acentuados aumentos nas capturas com evidentes tend?ncias de queda na produ??o, devem ser observados com cautela no que diz respeito ? libera??o de novos financiamentos. ; ABSTRACT: 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 Corr?a, Bragan?a, Curu??, S?o Caetano de Odivelas, S?o Jo?o 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 Bragan?a. 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 Bragan?a 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 Bragan?a ocorrin three different regions: coast Amap?, coast Salinas and coast Bragan?a. 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 Bragan?a 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.
