To generate scientific knowledge of these fisheries, the researchers have used increasingly, the local ecological knowledge. The great advantage in using the LEC for evaluation of small-scale fishing is able to access past information not reported in the literature and require considerable investment in time and financial resources to be sampled. In this dissertation sought to increase information available on small-scale fishing in Rio Grande do Norte. In the first article we use information of the fishers to estimate the CPUE of current catches of 10 and 20 years ago and identify the species most captured in the same period and compare this information with landing records and data obtained from expert fishers. In the second article we analyze the information of the boats used in artisanal fisheries to check for a fleet operating on the same species exploited or are different fleets operating on different species. In the first article as stated by fishers, the results do not suggest any change in CPUE between 2003 and 2013. In addition to being good informants to establish ranks of species abundance for the target species, fishers also provided accurate estimates for the CPUE of the best catches in the current period (2013).The approach used in this study showed, once again, that fishers have an important and sometimes unique information. However, when this knowledge was compared with formal data, showed major differences. This heterogeneity of informants and data sources (data of fishermen and official data) may be the single best source of information for fishing in areas where there lack of scientific data and abundance of skilled fishers. In the second article, the results indicate that there are two different fleet acting on the same species. The division between small and large boats showed that small boats are the best option for small-scale fishers. Since there is no difference in the amount of captured species and obtained income and expenses of the vessels these categories are much smaller, generating more profits than the big boats.porAcesso AbertoPesca de pequena escalaSérie temporalReconstrução dadosConhecimento ecológico dos pescadoresEficiência tecnológica barcosVulnerabilidade espéciesmasterThesisCNPQ::CIENCIAS BIOLOGICAS: DESENVOLVIMENTO E MEIO AMBIENTE - PRODEMA
