Fish Stock Assessment: an Inductive Science with the Logical Form of “Primitive Magic”: Replacing an Inductive View with a Critical Rational One

Creator:: Corkett, C. J.
Abstract:: A logical analysis of the common fisheries models used in stock assessment has shown that they produce specific predictions with the logical form of existential statements, fail Karl Popper’s falsifiability criterion, and so cannot be falsified or tested by the empirical evidence. By contrast, the theoretical models of fisheries economics...

From the shore or from the water? Enforcement of resource rights under discrete enforcement technologies

Creator:: Enriquez, Aaron J, Albers, H. J., Finnoft, D. C., Dresdner, J. C., and Chavez, C. A.
Abstract:: Poaching is a major problem under the Chilean system of territorial use rights in fisheries (TURFs). Organizations of artisanal fishers that are granted spatial property rights through TURFs combat poaching by establishing their own enforcement. Although an organization must protect its benthic resources against poachers from both within the organization...

Rights-Based Fishery Management Systems in Marine Fisheries off Alaska

Creator:: Ginter, Jay J. C. and Muse, Ben
Abstract:: Rights-based management in federally managed fisheries off Alaska has evolved rapidly over the past decade. While license limited entry and individual quotas (with rights assignments to vessel owners) were the principle tools under consideration in the early 1990s, in 2002 a wider range of programs and program options are under...

A precautionary approach to aquaculture: the incorporation of risk and incertainty in the feasibility analysis of shrimp hatchery in Mexico

Creator:: Martinez-Cordero, F. J., Seijo, J. C., and Juarez, L. M.
Abstract:: Sustainable aquaculture can be achieved when risk and uncertainly are incorporated in the analysis of the activity. This paper presents a precautionary approach to the feasibility analysis of a project for a commercial hatchery, applying decision theory. Two production scenarios were assessed, continuous and periodic, the later a combination of...

Biological and economic consequences of alternative SP-ALB stock recovery trajectories

Creator:: Skirtun, Maggie, Pilling, G. M., Reid, C., and Hampton, J.
Abstract:: South Pacific albacore is a species of primary importance in the longline fishery of a number of Small Island Developing States in the Western and Central Pacific Ocean. Despite the fact that the stock is assessed as not being subject to overfishing, nor overfished, economic returns have declined significantly over...

Advancing assessment methods for data-limited fish stocks

Creator:: Mildenberger, Tobias, Berg, C. W., Kokkalis, A., Pedersen, M. W., and Mielsen, J. R.
Abstract:: The assessment of data-limited fish stocks is crucial for the sustainable management of marine living resources. Dependent on the scope and type of available data, a range of assessment methods are available, such as catch-only, length-based, or catch and survey-based methods. However, these methods suffer from several shortcomings, such as...

Racing for Crabs: Difficult Management Options in California's Commercial Dungeness Crab Fishery

Creator:: Dewees, Christopher M., Sortais, Kristen, Krachey, Matthew J., Hackett, Steven C., and Hankin, David G.
Abstract:: Dungeness crab (Cancer magister) supports a valuable commercial fishery along the Pacific coast of North America. In recent decades the fishery has intensified significantly, with most crab landed during the first six weeks of the seven-month season. Management approaches to slow this intensifying and dangerous race have been elusive. This...

Demand for Organic Salmon in the European Union

Creator:: Tvetaras, R., Aarset, B., Beckmann, S., Bigne, J., Beveridge, M., Bjorndal, T., McDonagh, P., Mariojouls, C., Muir, J. F., Prothero, A., Reithe, S., Smith, A. P., Tveteras, S., and Young, J. A.
Abstract:: This paper provides an analysis of the market potential for organic salmon, primarily in the European Union. There has been a substantial growth in the demand for organic food products in industrialised countries in the course of the past decade. Legislation for organic production is now being extended to aquaculture,...

Modelling spatial interactions among fish communities, fishers and other marine activities: comparing five European case-studies

Creator:: Bastardie, Francois, Rufener, M. C., Nielsen, J. R., Maina, I., Kavadas, S., Vassilopoulou, C., Alexandrov, L. M., Niculescu, D., Spinu, A., Nicolaev, A., Rosca, M., Hoffle, H., Farnsworth, K. D., Pedreschi, D., Reid, D., Bolognini, L., Martinelli, M., Grati, F., and Fuga, F.
Abstract:: Sophisticated computer simulations can support effective science-based evaluations to facilitate better governance of the marine space. We developed a range of spatial fisheries models, integrating biological with fisher decision-making dynamics and management for assessing management of multiple activities. We present the outcomes of case-specific evaluations with different ecological and socio-economic...
