Creator:: Gasalla, Maria A., Rodrigues, Amanda R., Duarte, Luis F. A., and Sumaila, U. Rashid
Abstract:: A comparative multi-fleet rationale of socioeconomic indicators is described aiming a potential incorporation into fishery management advice at an ecosystem scale. A set of performance indicators, based on a survey of different industrial fishing fleets in São Paulo (SE Brazil) which investigated investment, fixed, effort, labour and sailingrelated costs and...
Resource Type:: Research Paper

Creator:: Ngoc, Quach Thi Khanh and Flaaten, Ola
Abstract:: This paper investigates interactions between recreational and commercial fisheries. It introduces the idea of a protected area for recreational fisheries, as a way to reduce conflicts between the two sectors and to preserve the natural resource. It is demonstrated that without a protected area for recreational fisheries, open access may...
Resource Type:: Research Paper

Creator:: Harte, Michael, Rosenberger, Randall, Sylvia, Gil, and Heppell, Selina
Abstract:: Existing research on the effectiveness of marine protected areas narrowly focuses on developing sets of management indicators tied to outcomes described in management plans or on the achievement of a single objective such as an increase in the size or number of older, more fecund female fish in a protected...
Resource Type:: Research Paper

Creator:: Aanesen, Margrethe, Armstrong, Claire, and Kahui, Viktoria
Abstract:: The push for ecosystem based management has opened up not only for including more of the natural systems when managing fish resources, but also a broader perspective on the human systems, and the diverse activities in the sea. This is reflected for instance in the EU Maritime Policy where fisheries...
Resource Type:: Research Paper

Creator:: Curtin, Richard and Martinet, Vincent
Abstract:: This paper examines the viability of the management of a transboundary resource, the Bay of Biscay anchovy (Engraulis encrasicolus L.). A deterministic model is used to simulate the anchovy dynamics, with the fish stock consisting of two age groups, “young" and “old", while recruitment follows a Beverton Holt pattern. Two...
Resource Type:: Research Paper

Creator:: Long, Le Kim and Flaaten, Ola
Abstract:: To ensure the long-term conservation and sustainable use of straddling fish stocks, the 1995 United Nations Fish Stock Agreement calls for the establishment of regional fisheries management organizations to manage such stocks. This paper studies the potential for cooperation in straddling stock fisheries when the cooperative coalition of countries acts...
Resource Type:: Research Paper

Creator:: Van Dijk, Diana, Costello, Christopher, Van Dijk, David, Groeneveld, Rolf, and Van Ierland, Ekko
Abstract:: Yearly revisions of Total Allowable Catch under EU policies for the management of North Sea fisheries come at high management costs and capital adjustment costs. It is unclear whether current EU fisheries policy strikes the right balance between the need to regularly adjust fish quota to new information on one...
Resource Type:: Research Paper

Creator:: De Lara, Michel, Ocana, Eladio, Oliveros-Ramos, Ricardo, and Tam, Jorge
Abstract:: We define the notion of sustainable yields for ecosystem, with particular emphasis on long-run consistency between ecological and economic conflicting objectives. We provide a way to compute sustainable yields by means of a viability analysis of generic ecosystem models with harvesting. We apply our approach to a Lotka–Volterra model of...
Resource Type:: Research Paper

Creator:: Martinet, Vincent, De Lara, Michel, Peña-Torres, Julio, and Ramirez, Héctor
Abstract:: This paper develops a theoretical framework to assess resources management procedures from a sustainability perspective, when resource dynamics is marked by uncertainty. Using stochastic viability, management procedures are ranked according to their probability to achieve economic and ecological constraints over time. This framework is applied to a fishery case-study, facing...
Resource Type:: Research Paper

Creator:: McLeod, Paul, Lindner, Bob, McElroy, James Kevin, and Nicholls, John
Abstract:: Australia’s western rock lobster fishery is its most valuable and hence from a biological perspective most tightly managed major commercial fishery, yet it has been beset by problems of miniscule recruitment over the past 3 years. This coming year 2010-11 is little better. It was the joint first Marine Stewardship...
