It was used landing information, capture estimates and data reconstruction of octopus catches between 1994 and 2010 to evaluate the capture of O. insularis in RN. These information was provided by the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA) and the Sea Around Us Institute. All analyzes of temporal series for octopus catches in RN were performed with the median values of CPUE (kg/Day*Nº Fishermen). It also tested models of maximum sustainable catch of Schaefer and Fox from data of capture and effort. The RN State was the fourth largest octopus producer in Brazil during the years 2001 to 2007 and, among these is the only State where fishing is carried out by artisanal way exclusively. Catch records in RN started in 1994 (199.4 tons), and since then have increased with catches over 100 tons, reaching a peak of 478.5 tons in year 2006. Among the cities that capture octopus in RN, Rio do Fogo (RF) stands out as the main producer with the highest median value of CPUE (4.67 kg/Day*Nº Fishermen). The CPUE has a slight decrease at the beginning of the temporal series, increases significantly until year 2009 and then, has a expressive drop in 2010. The analysis of O. insularis catches suggest that this resource is still at sustainable levels in Rio Grande do Norte, since the catch and effort observed in the analyzed period are lower than the maximum sustainable yield showed by the fishing models. There was an increase in number of small boats over the years. In 2005 the small boats were 41.9% of the total fleet, while in 2010 they already accounted for 82.7% of the municipal fleet. There was no significant variation in fishing effort in the analyzed years and the increased ofcatches are not related to increased efforts or even to appearance of new technologies because the fishing methods have not changed over the years.Acesso AbertoCapturasSérie temporalModelos de produção excedenteManejoEstratégias de exploração e comércio da pesca artesanal de polvodoctoralThesisCNPQ::CIENCIAS BIOLOGICAS::ECOLOGIA
