Analysis of Brazilian fishers' classifications of 24 marine (Atlantic coast) and 24 freshwater (Amazon) fish species reveals that fishers from the Atlantic coast identify fish mainly through generic names (primary lexemes), while riverine Amazonian fishers typically identify them through binomials. The similarity of Amazonian fish species seems to contribute to the detailed folk taxonomy used by riverine fishers. Highranking groups called "relatives" or "cousins" are sorted by fishers in terms of similarities of habitat, diet, and morphology and, secondarily, behavior. The general correspondence between the folk and scientific taxonomies reinforces the reality of both the supracategories used by these fishers and the biological groups as discontinuities in nature. Given the urgency of biological inventories and the lack of knowledge of high-biodiversity environments such as the Atlantic Forest and the Amazon, these results suggest that fisher knowledge and experience could contribute to scientific research. The reality of species has been the subject of debate since the early days of evolutionary biology. Darwin defined species as varieties that are well demarcated and defined and actually exist at a certain point in time, but his analysis left open the possibility that species might be arbitrary constructions of the human mind (Darwin 1859a [1982], 1859b; Coyne and Orr 2004). The term "species" is vague because it includes both

We compared fish abundance, diversity and species composition between lakes open (fished) and closed (no-take) to fishing activities in Mamirauá Sustainable Development Reserve in the Central Brazilian Amazon, in order to investigate potential influences of the common-based management. We sampled 1483 fishes from 70 species through gillnet fishing during the low-water season, in seven fished and seven no-take lakes. Contrary to expected, the mean values for abundance, size, diversity and species-richness of fish did not differ between fished and no-take lakes. There was no difference between fished and no-take lakes considering only the abundance of the 14 fish species more intensely targeted by fishermen. However, the abundance of an important commercial fish, the tambaqui (Colossoma macropomum) was higher in no-take lakes. Such data from a rapid assessment may be useful to monitor this and other fishery co-management schemes.

Recreational fisheries in Brazil have increased in importance and attracted many foreign recreational fishers. The objectives of this article were to summarise the available data on Brazilian recreational fisheries, to discuss some of their features and to analyse how they are performing in different regions compared with international trends. A review of published and unpublished sources together with data from recreational fishing licences was used. The participation rate was low (0.9%). Overall, there was a high diversity of fish species, with the following species/group of species repeatedly reported: Menticirrhus spp., Centropomus spp., Cynoscion spp., and Micropogonias furnieri (marine/estuarine water), and Cichla spp., Hoplias malabaricus, and Piaractus mesopotamicus, together with the introduced Oreochromis niloticus and Coptodon rendalli (fresh water). The north‐eastern region differs from the other regions: fishing occurs mostly in marine waters and fishers acquire mainly shore‐based licences, have minimum fishing expenditures and rarely release fishes. There is no estimate of the total harvest or economic value. Conflicts include catch‐and‐release‐oriented freshwater and marine recreational fishers vs consumption‐oriented coastal fishers, tournament participants vs non‐participants, commercial fishers and other leisure activities, pollution, ports, species introductions and translocations, protected areas, and federal and state laws. Cases of smooth shifts from artisanal to recreational fishing were detected, possibly associated with changes in the societal relationship with natural resources.

In this study we compare the dynamics of artisanal fishery in two adjacent reserves located in the Brazilian Amazon, Mamirauá (being managed for more than 12 years) and Amanã (initiating a management process), through the record of 485 fish landings in one fishing community in each reserve during high and low water seasons in 2003. Our goals were, first, to make a rapid and comparative assessment of some main aspects of fisheries in these two communities (fish species caught, CPUE, fishing gear and habitats exploited). Second, we used such data to evaluate if management strategies already in place in Mamirauá would be also valid for Amanã . Third, we compared fishing CPUE between the two communities, in order to check if co-management measures have contributed, at least partially, to preclude over-fishing, maintaining a higher fishing reward in Mamirauá reserve. We analyzed fisheries directed to the two most important marketable fishes in the region: the pirarucu (Arapaimas gigas) and the tambaqui (Colossoma macropomum), besides those fisheries aimed to subsistence and lower valued fishes. Our results indicated that the tambaqui was intensively fished year-round in Mamirauá , while Amanã fishers caught a higher variety of fishes, including catfishes and migratory scale fishes. Such differences might reflect differences in gear used and habitat exploited by fishers during the high water season. Mamirauá fishers caught a higher fish biomass considering both marketable and all fishes. Differences in gear used, habitats exploited and fishes caught during high water season indicate that distinct management initiatives might apply for each reserve. Notwithstanding their differences, both communities exploited the commercial fishes (tambaqui and pirarucu) in a similar way during the low water season. Therefore, the higher mean fishing yield (CPUE) observed in Mamirauá may be partially Handling editor: S. M. Thomaz attributable to co-management measures, considering that Mamirauá has possibly been experiencing a higher fishing intensity than Amanã . Fishing related data are seldom available in Brazil and other tropical developing countries. We thus provided a framework of fast assessment of fishing dynamics, which may represent a first and useful step for management initiatives in the absence of more detailed data.

BackgroundData derived from studies of fishers’ local ecological knowledge (LEK) can be invaluable to the proposal of new studies and more appropriate management strategies. This study analyzed the fisher’s LEK about trophic relationships of fishes in the southeastern Brazilian coast, comparing fishers’ LEK with scientific knowledge to provide new hypotheses.MethodsThe initial contacts with fishers were made through informal visits in their residences, to explain the research goals, meet fishers and their families, check the number of resident fishers and ask for fishers’ consent to participate in the research. After this initial contact, fishers were selected to be included in the interviews through the technique of snowball sampling. The fishers indicated by others who attended the criteria to be included in the research were interviewed by using a semi-structured standard questionnaire.ResultsThere were interviewed 26 artisanal fishers from three communities of the Ilhabela: Jabaquara, Fome and Serraria. The interviewed fishers showed a detailed knowledge about the trophic interactions of the studied coastal fishes, as fishers mentioned 17 food items for these fishes and six fish and three mammals as fish predators. The most mentioned food items were small fish, shrimps and crabs, while the most mentioned predators were large reef fishes. Fishers also mentioned some predators, such as sea otters, that have not been reported by the biological literature and are poorly known.ConclusionsThe LEK of the studied fishers showed a high degree of concordance with the scientific literature regarding fish diet. This study evidenced the value of fishers’ LEK to improve fisheries research and management, as well as the needy to increase the collaboration among managers, biologists and fishers.

RESUMOA pesca artesanal é uma das principais atividades econômicas de comunidades pesqueiras brasileiras e importante fonte de proteína animal para muitas famílias. Estas comunidades que vivem em contato direto com o ambiente natural e dependem economicamente dos recursos naturais podem fornecer informações importantes para o delineamento de propostas de conservação e manejo visando à sustentabilidade. Desta forma, o objetivo deste trabalho foi caracterizar a pesca artesanal e os aspectos socioeconômicos dos pescadores artesanais de Fernando de Noronha/PE. Os dados foram coletados através de entrevistas semiestruturadas e analisados qualitativa e quantitativamente. Foram entrevistados 62 pescadores e os resultados demonstraram que a pesca artesanal é realizada para consumo próprio ou como fonte de renda. Em função das áreas prioritárias para conservação, a área de pesca é um dos maiores conflitos verificados no arquipélago. Na busca pela complementação da renda, atividades paralelas, principalmente ligadas ao turismo, vêm sendo desenvolvidas. O "corrico" é o petrecho mais utilizado e tem baixo impacto ambiental, sendo a albacora (Thunnus albacares) e o xaréu-preto (Caranx lugubris) as espécies mais capturadas. Embarcações maiores e mais potentes permitem a pesca em locais mais afastados, e o não uso de gelo na conservação do pescado foi evidenciado. Os dados indicam a importância da elaboração de um plano para gestão compartilhada dos recursos, resultando na valorização do pescador artesanal e a sustentabilidade da atividade pesqueira.

These communities living in direct contact with the natural environment and economically dependent on natural resources can provide important information for the design of conservation and management proposals aimed at sustainability. Thus, the aim of this study was to characterize artisanal fisheries and socio-economic aspects of artisanal fishermen of Fernando de Noronha/PE. Data were collected through semi-structured interviews and analyzed qualitatively and quantitatively. 62 fishermen were interviewed and the results showed that artisanal fishing is practiced for own consumption or as a source of income. epending on the priority areas for conservation, fishing area is one of the biggest conflicts recorded in the archipelago. In the search for supplementary income, parallel activities, especially related to tourism, has been developed. The "corrico" is the most used gear and has low environmental impact, and yellowfin tuna (Thunnus albacares) and the black jack (Caranx lugubris) are the species more caught species. Larger and more powerful vessels allow fishing in more remote locations, and not using ice on fish conservation was evident. Data indicate the importance of developing a plan for...

This article investigates the folk taxonomy of four artisanal fisheries communities in Ilhabela/SP. The local folk taxonomy shows how these fishermen identify, name and classify fish resources in the environment exploited by them. Forty-two fishermen from four different local communities of Ilhabela were interviewed through a structured questionnaire and photographs of fish species with occurrence for the southeast region of Brazil. Respondents identified the 24 species listed as 50 generic names and 27 binominal specific names, mainly related to aspects of fish species morphology such as color, shape and size. These fish were classified into eight groups according to local criteria related to the morphology, ecology and fishing forms associated with the capture of species. The morphological aspect was identified as the most used feature by respondents to name and classify local fish, followed by ecological aspects such as behavior, diet and habitat. The comparison of local criteria used for the groups was similar to the scientific taxonomy criteria, showing a detailed local ecological knowledge by this group of fishers. Resumo: Este artigo investiga a etnotaxonomia de quatro comunidades de pescadores artesanais de Ilhabela/SP. A etnotaxonomia mostra como esses pescadores, identificam, nomeam e classificam os recursos pesqueiros no ambiente explorado por eles. Quarenta e dois pescadores de quatro diferentes comunidades locais de Ilhabela foram entrevistados através de um questionário estruturado e fotografias de espécies de peixes de ocorrência para a região sudeste do Brasil. Os entrevistados identificaram as 24 espécies listadas através de 50 nomes genéricos e 27 nomes específicos binomiais, principalmente relacionados com aspectos morfológicos como forma, cor e tamanho. Estes peixes foram classificados em oito grupos de acordo com critérios locais relacionados com a morfologia, ecologia e técnicas de pesca associados à captura de tais espécies. O aspecto morfológico foi identificado como o fator mais utilizado pelos entrevistados para nomear e classificar as espécies de peixes, seguidos por critérios relacionados à ecologia das espécies tais como, dieta, comportamento e habitat. A comparação dos critérios locais utilizados para os grupos foi semelhante aos critérios científicos de taxonomia, mostrando um detalhado conhecimento ecológico local deste grupo de pescadores.

This study was conducted in three communities of artisanal fishermen from Ilhabela, located on the northern coast of São Paulo, Brazil. The objective was to analyze the preferences, taboos and medicinal indications of fish and thus representing one of the interactions of fishermen with fish stocks. Data collection was conducted through interviews with the aid of semi-structured questionnaires. We interviewed 25 families, 29 residents in three communities studied during our fieldwork for data collection. Five interviews were done in Jabaquara Beach, 6 in Fome Beach and 14 Serraria Beach. During the interviews, 18 species were cited as preferred for consumption, 11 species considered to be taboo (food prohibited), 5 species were cited as avoided as food, and 4 species indicated in case of illness. The families of fishermen prefer to consume finfish and do not consume puffer fish, the latter probably due to its toxic characteristic. Fish such as little tunny, largehead hairtail, shark, serra mackerel and king mackerel are avoided by unhealthy people and in cases of wounds, inflammation, pregnancy and postpartum. Other fish, such as sea chubs, silver porgy, bluefish and grouper are reported as medicinal in these situations. Aspects related to fish consumption are part of the knowledge of fishermen and their families and provide a wealth of information that combined to biological information is useful for the conservation of fishery resources. Data such as those presented in this study, regarding the use of aquatic animals for treatment of diseases, could serve as a basis for future studies on substances that contain active elements in curing diseases. Resumo: Este trabalho foi realizado em três comunidades de pescadores artesanais de Ilhabela, localizadas no litoral norte do Estado de São Paulo, Brasil. O objetivo foi analisar as preferências, os tabus e as indicações medicinais dos peixes e, desta forma, representar as interações dos pescadores com os recursos pesqueiros, visando entender os aspectos biológicos e culturais envolvidos. A coleta dos dados foi realizada através de entrevistas com o auxílio de questionários semi-estruturados. Foram entrevistadas 25 famílias, das 29 residentes nas três comunidades estudadas durante a coleta de dados, sendo que 5 delas foram realizadas na Praia do Jabaquara, 6 na Praia da Fome e 14 na Praia da Serraria. Foram citadas 18 consideradas preferidas para o consumo, 11 espécies consideradas como tabus, 5 espécies evitadas e 4 indicadas no caso de doenças. As famílias de pescadores preferem consumir peixes de escama e não consomem o baiacu, este último provavelmente devido a sua característica tóxica. Peixes como bonito, espada, cação, sororoca e cavala são evitados em casos como feridas, inflamações, gravidez e pós parto e outros como pirajica, marimba, anchova e garoupa são indicados como peixes medicinais nestas situações. Aspectos relativos ao consumo de pescado fazem parte do corpo de conhecimento dos pescadores e suas famílias e constituem um acervo rico de infor...
