A future for marine fisheries in Europe (Manifesto of the Association Francaise d'Halieumetrie) ArchiMer
Gascuel, D.; Bez, Nicolas; Forest, Andre; Guillotreau, P.; Laloe, F.; Lobry, Jeremy; Mahevas, Stephanie; Mesnil, Benoit; Rivot, Etienne; Rochette, S.; Trenkel, Verena.
We, members of the Association Francaise d'Halieumetrie, share the conviction that European fisheries have a future. It is time to get off the wrong track. Radical change is required to embark on the path of sustainable development and truly implement the ecosystem approach to fisheries. Today, high fishing pressure is deployed to catch a rare resource, which in return is responsible for the rarity. We must reverse the situation: an abundant resource that affords high catches applying moderate fishing pressure. All management tools and especially all actors must be mobilized. The transition is not simple, and European solidarity must accompany the changes. It is well worth the effort. By reducing fishing pressure, it will be possible in the medium term to...

Achieving maximum sustainable yield in mixed fisheries: a management approach for the North Sea demersal fisheries ArchiMer
Ulrich, Clara; Vermard, Youen; Dolder, Paul J.; Brunel, Thomas; Jardim, Ernesto; Holmes, Steven J.; Kempf, Alexander; Mortensen, Lars O.; Poos, Jan-jaap; Rindorf, Anna.
Achieving single species maximum sustainable yield (MSY) in complex and dynamic fisheries targeting multiple species (mixed fisheries) is challenging because achieving the objective for one species may mean missing the objective for another. The North Sea mixed fisheries are a representative example of an issue that is generic across most demersal fisheries worldwide, with the diversity of species and fisheries inducing numerous biological and technical interactions. Building on a rich knowledge base for the understanding and quantification of these interactions, new approaches have emerged. Recent paths towards operationalizing MSY at the regional scale have suggested the expansion of the concept into a desirable area of “pretty good yield”, implemented...

Cobertura vegetal do Parque Estadual Pantanal do Rio Negro (PEPRN) - MS. Repositório Alice
ABDON, M. de M.; SILVA, J. dos S. V. da; POTT, A.; POTT, V. J.; SILVA, M. P. da; MENGATTO JÚNIOR, E. A..
Este trabalho tem por objetivo a elaboração do mapa da cobertura vegetal na escala de 1:50.000 do Parque Estadual Pantanal do Rio Negro, MS, para fins de plano de manejo. A legenda do mapeamento da cobertura vegetal foi baseada no sistema fisionômico-ecológico do IBGE, seguida das denominações regionais. A seguinte seqüência metodológica foi seguida: a) georreferenciamento, realce e mosaico das imagens, b) aplicação de segmentação por crescimento da região, c) interpretação visual de imagens digitais obtidas pelo satélite Landsat-TM, ano 2002, d) informações georreferenciadas (foto e identificação fisionômica) com GPS obtidas em trabalho de campo, e) análise e comparação com trabalhos já existentes, f) elaboração de mapas preliminares, g) correção dos...

Environmental and ecological architects: Guidelines for the Chilean temperate rainforest management derived from the monito del monte (Dromiciops gliroides) conservation RChHN
FONTÚRBEL,FRANCISCO E; JIMÉNEZ,JAIME E.
Land use change is one of the main biodiversity threats. Due to this change, natural habitats such as the South American temperate rainforests have been rapidly degraded, fragmented, and lost. Consequently, the management and conservation of the remaining forest is a priority and having an appropriate environmental policy is mandatory for this purpose. Conservation actions in the temperate rainforest have been addressed from an individual species perspective, giving less attention to the ecosystem level conservation. Moreover, conservation-related information has not reflected yet on environmental policy development. We used the case study of the monito del monte (Dromiciops gliroides) to illustrate how our current ecological and conservation knowledge of...

Integration of biological, economic and sociological knowledge by Bayesian belief networks: the interdisciplinary evaluation of potential Baltic salmon management plan AgEcon
Levontin, Polina; Kulmala, Soile; Haapasaari, Paivi; Kuikka, Sakari.
There is a growing need to evaluate fisheries management plans in a comprehensive interdisciplinary context involving stakeholders. In this paper we demonstrate a probabilistic management model to evaluate potential management plans for Baltic salmon fisheries. The analysis is based on several studies carried out by scientists from respective disciplines. The main part consisted of biological and ecological stock assessment with integrated economic analysis of the commercial fisheries. Recreational fisheries were evaluated separately. Finally, a sociological study was conducted aimed at understanding stakeholder perspectives and potential commitment to alternative management plans. In order to synthesize the findings from these disparate studies a Bayesian...
