“…Clearly, understanding the preferential habitats of species and their trophic relationships, especially of apex predators like dolphins, is important to identify and predict potential threats as a precursor to both species conservation and fishery-resource management (e.g. fishing effort) in the PEC (Bisi et al, 2013;Hardt et al, 2013;Sedrez, Branco, Freitas Junior, Moteiro, & Barbieri, 2013).…”

1. Estuaries are critical to the life histories and development of many marine species, and support some of the most productive aquatic ecosystems. But, owing to their geographic accessibility, many estuaries face considerable anthropogenic threats, which can be exacerbated in developing nations. 2. Understanding the ecological implications of anthropogenic activities as a precursor to dedicated conservation activities requires comprehensive assessments of baseline trophic relationships. This study addresses a shortfall in such information for two tropical, coastal ecosystems globally identified as priority areas for biodiversity conservation: the Paranaguá estuarine complex and Cananéia-Iguape estuarine lagoon system in southern Brazil. 3. Ecological relationships were investigated through carbon and nitrogen stable isotope (δ 13 C and δ 15 N) determination in sediments, plant fragments and the muscle tissues of marine species occupying different trophic levels, including benthic invertebrates, This article is protected by copyright.

“…Trawling with motorized traction for catching shrimp is performed with fine mesh nets that are powered by engines. These nets drag the ocean floor and capture developing species and maritime flora, with no selective processes, and are therefore able to change the structure of the coastal ecosystem, thereby endangering the sustainability of target species, the accompanying fauna and the entire surrounding biological community (Sedrez et al, 2013).…”

Artisanal marine fishing is practiced throughout all the coastal cities in the southern region of the State of Bahia (Brazil); it provides an economic and cultural base of support for local families. Using action-research as an investigatory method while treating traditional knowledge from the actors in the region as an indispensable information source, this study aimed to identify the main socio-environmental conflicts that exist in an artisanal fishing community located in the south of Bahia, Brazil. The research methods used in this article, starting with the action-research that allows the researcher to have access to the community with a view to jointly look for solutions to specific problems, following a cycle where there is systematic oscillation between actions in the field of practice and its investigation. In this way, it was possible for the authors to provide educational assistance which included performing diagnostics, training initiatives, productive structuring, introducing new income sources and searching for markets for the fishermen's products, and at the same time, undertaking socioeconomic and environmental research at the heart of the community. Thus, the authors were able to verify that the local fishing environment is considered, by local fishermen and those from other regions, as one of the major fishing areas in southern Bahia. This characteristic means that the situation is dichotomous, because on the one side it is a matter of interest for artisanal fishermen in the local community, on the other hand, other fishermen from different regions of the country end up being attracted in order to catch fish, thereby generating conflict among local artisanal fishermen. The action-research method made it possible to verify six types of conflict: i) conflict with recreational amateur anglers; (ii) trawl fishing on the beach; (iii) using the net method for catching shellfish; (iv) picking up shellfish while they walk on the surface; (v) reluctance to using safety equipment; (vi) closed season for snook fishing. When focusing on the relationship with amateur fishermen it is possible to see, according to native fishermen, that these individuals can contribute to the local stock depletion due to the practices adopted by these fishermen; which therefore makes this conflict of primary importance among all the others that were analyzed. It was noticed that supervision and law enforcement by competent bodies is a rare thing in this analyzed fishing environment and thus, the fishermen seek partnerships through their association with various regional actors in order to find solutions to conflicts and to encourage community development.

“…Também não há definição de parâmetros para a fauna acompanhante, representada por mais de 70 espécies (BRANCO, 2005;BRANCO e FRACASSO, 2005;CATTANI et al, 2011;SEDREZ et al, 2012). Não há legislação específica, salvo para as espécies de interesse comercial que possuem medidas de ordenamento próprias.…”

RESUMODispositivos para a redução da captura da fauna acompanhante (BRD) são modificações tecnológicas instaladas em redes de arrasto a fim de evitar ou reduzir a mortalidade indesejada oriunda da pesca. Foram examinadas as perspectivas para o uso de BRD na pesca artesanal de arrasto na costa sul brasileira a partir de uma revisão em três níveis. A primeira tratou de uma breve descrição da gestão pesqueira no Brasil (GP). A seguir, foram revisados conceitos a partir do enfoque ecossistêmico aplicado à pesca (EAF) e da cogestão adaptativa (ACM). Por fim, os resultados dos experimentos com o uso de BRDs na pesca artesanal do litoral do Paraná foram sintetizados e analisados com base em três critérios provenientes do EAF e ACM (potencial para processos participativos, diálogo de saberes e gestão adaptativa). Foram identificados quatro ciclos institucionais que demonstram condições limitadas para a adoção de novas abordagens da gestão, especialmente a adoção de BRD além de uma modificação técnica. Contudo, partindo de uma perspectiva ampliada de gestão, torna-se importante testar os BRDs em diferentes contextos, a partir da compreensão avançada da dinâmica dos sistemas pesqueiros artesanais, da participação efetiva dos pescadores, do uso de abordagens participativas de pesquisa e de gestão, do envolvimento gradativo dos gestores nos experimentos e de uma comunicação contínua sobre resultados dos experimentos para os diferentes espaços de gestão pesqueira. Palavras chave: Xiphopenaeus kroyeri; gestão ecossistêmica; modificações tecnológicas; cogestão adaptativa STRATEGIES FOR BYCATCH REDUCTION AT SMALL-SCALE SHRIMP TRAWL FISHING: PERSPECTIVES FOR FISHERIES MANAGEMENT ABSTRACTBycatch reduction devices (BRD) are technical modifications installed in trawl nets in order to avoid or to reduce unwanted fishing mortality. We examined the perspectives of use of BRD on the Southern Brazilian artisanal trawl fishery at three levels. Firstly, we briefly described Brazilian Fisheries Management (BFM) from the past 50 years. Secondly, we reviewed concepts in Ecosystem Approach to Fisheries (EAF) and Adaptive Co-Management (ACM) approach. Finally, we summarized some of the findings from experiments with the use of BRD on a small-scale fishing boat at the coast of Paraná based on three criteria from EAF and ACM (potential for participatory approach, knowledge bridging and adaptive management). We identified four institutional cycles, which showed limited conditions to the adoption of new fisheries management approaches, especially in terms of the adoption of BRD beyond a technical modification. However, from a wider fisheries management perspective, it's important to experience BRDs in different scenarios, through comprehension of dynamic of fisheries systems, participation of fishers, use of participatory approaches on research an management, engagement of decision makers, and the continued communication between experiments and fisheries management arenas.
