“…MPAs may trigger redistribution and concentration of fishing effort in adjacent areas, potentially leading to overexploitation. As a consequence, MPAs may need to be supplemented with additional measures outside their boundaries (Murray et al 1999) [27]. The socio-economic benefits of MPAs are difficult to predict in advance due to the limited predictability of the biological responses (Farrow 1996) [28], and because non-market values, such as biodiversity, are difficult to assess (Carter 2003) [29].…”

Painting the floor with a hammer: Technical fixes in fisheries management

Fisheries management benefits from the contribution of several academic disciplines, each with their own perspectives, concerns and solutions. In this essay we argue that the contribution of biology, economics, sociology and other relevant disciplines to fisheries would be improved if they originated from broader, more integrated analytical perspectives that are attuned to the empirical realities of fisheries management. Today, disciplinary boundaries narrow the perspectives of fisheries management, creating tunnel vision and standardized technical fixes to complex and diverse management problems. Having worked separately and together for a number of years in fisheries research and consultancy in many parts of the world we, as a group of biologists, economists and sociologists, feel that the time to rid ourselves from disciplinary dogmatism is long overdue. We claim that improvements in fisheries management will be realized not through the promotion of technical fixes but instead by embracing and responding to the complexity of the management problem.2

“…Essa conectividade de habitats tem sido considerada como um aspecto chave na concepção de redes integradas de áreas marinhas protegidas para a conservação da biodiversidade (MURRAY et al, 1999;FRIEDLANDER et al, 2003). Embora muitos estudos tenham se concentrado na identificação de habitats essenciais para a manutenção do ciclo de vida das espécies (STONER, 2006), ainda se conhece pouco sobre a importância e a conectividade entre habitats costeiros, seja esta com estuários adjacentes (ABLE, 2005) ou com outros habitats próximos, como a zona de arrebentação de praias arenosas e ambientes recifais.…”

ABSTRACT. Associations of fishes in the coastal region of Itaipu, Niterói. The coastal region of Itaipu, Rio de Janeiro forms a partially sheltered sound, protected by three islands, but still maintaining full communication with the open sea. The sound also receives fresh water input from the Itaipu-Piratininga lagoon system, constituting an area of intense artisanal fisheries. Using data from monthly monitoring of the artisanal fisheries (beach seining, gill netting and hand lining), experimental surf zone beach seine surveys, underwater visual census (Menina, Mãe, and Pai islands), and a multisampling experiment at Itaipu Lagoon, we elaborated a list of fish species occurring in the region, observing their connectivity with different local habitats, including the sound, rocky reefs, the surf zone and Itaipu Lagoon. We identified 183 species including 26 Elasmobranchii, grouped in 13 families, and 157 Actinopterygii grouped in 63 families. The artisanal beach seining caught the greatest number of species (112), followed by the gill netting (94) and hand lining (35). The surf zone beach seining ("picaré") yielded 49 species (8 exclusive) represented mostly by juvenile fish and species of little economic importance. Visual censuses resulted in 41 species identified, with 21 exclusive and most of them cryptic. Within the Itaipu lagoon, 46 species were recorded, 18 exclusive and of occasional occurrence. Cluster analysis including 106 non exclusive species resulted in the formation of eight different groups. Groups A and B were composed by species captured exclusively by the artisanal fisheries within the sound, and included species of commercial interest. Group C included species occurring in the fisheries whose juveniles are found in the surf zone. Group D classified species of common occurrence in the fisheries and the islands. Group E was represented by species shared by the fisheries and Itaipu lagoon (mullets, mojarras, herrings). Species from group F were absent in the islands, those from group G in the lagoon, and those from group H were common to all areas considered. Compared with other coastal areas in southeastern Brazil, Itaipu represents an important concentration area for fish biological diversity and biomass, yielding species associations and connectivity between the different local habitats. KEYWORDS.Itaipu, species list, fishes, artisanal fisheries, habitat connectivity. RESUMO.A região costeira de Itaipu, Rio de Janeiro é guarnecida por três ilhas, formando uma enseada semi-abrigada porém com ampla comunicação com o mar. Esta enseada recebe o aporte de águas do complexo lagunar Itaipu-Piratininga, além da influência de massas d'água oceânicas, constituindo uma área de intensa atividade pesqueira artesanal.

“…MPAs are promoted globally as a tool for managing fisheries, conserving species and habitats, maintaining ecosystem functioning and resilience, preserving biodiversity, and protecting the myriad of human values associated with the ocean [2][3][4][5]. Ecologically, MPAs have been shown to be effective at protecting or reducing degradation of habitats and ecosystems [4,6,7] and increasing biomass and species diversity, richness, and numbers [8,9].…”

From measuring outcomes to providing inputs: Governance, management, and local development for more effective marine protected areas

Marine protected areas (MPAs) have the potential to conserve marine resources as well as provide social and economic benefits to local communities. Yet the percentage of MPAs that might be considered “successful” or effective on ecological and/or socio-economic accounts is debatable. Measurement of biophysical and socio-economic outcome indicators has become de rigeur for examining MPA management effectiveness so that adaptive feedback loops can stimulate new management actions. Scholars and practitioners alike have suggested that more attention should be given to the inputs that are likely to lead to successful MPA outcomes. This paper briefly discusses the potential ecological and socio-economic outcomes of MPAs then reviews the literature on three categories of inputs – governance, management, and local development – that lead to effective MPAs. In conclusion, the paper presents a novel inputs framework that incorporates indicators for governance, management and development to be used in the design and analysis of MPAs.
