La cuenca del Salado: uso y posibilidades de sus recursos pesqueros.

The fishing resources of the Salado Basin are extraordinary important in the context of the inland waters of Argentina. However, the diversity of landscapes in the basin and the lack of continuity in the regional planning , have made difficult a proper management of the fishing resources. This paper has a general overview of the main aspects related to the fishing fauna of the region, with a natural point of view of the processes and mechanisms of the management. A description of the fishes basin community and the identification of the species with commercial and game interests is included . We describe the different fishing gears used in the province for game, commercial and scientific fishing. We review the criteria of diagnosis of the silver side population as a main resource of fishing interest and under this point of view we propose new outlooks to promote a proper management of the resources and its sustainable use. We identify the different kinds of fisheries that are common in the basin and we make a survey of the related socioeconomic aspects. Moreover, we analyze the development of a new institutional and regulatory frame in order to optimize the management of the fishing resources. Finally, we define criteria for ordering and conserving such resources and identify conflict points and requirements for its sustainable use in the context of new proposals for the public policies.

Economics and management strategies for restocking sandfish in Vietnam

This paper assesses the costs and benefits of a proposed project for restocking sandfish (Holothuria scabra) in Khanh Hoa Province, Vietnam. It identifies the key stakeholders, institutional framework, management and financing required for its implementation. The recommended management strategy includes a 50 percent harvest at optimum size. Limiting the number of boats fishing an area, possibly through licensing, can control the number of sandfish removed. The easiest way to prevent harvesting of undersized sandfish is to control the size of processed sandfish from processors. The potential benefits of restocking are shown by the rapid changes in selected indicators, particularly the net present value, the internal rate of return, and the benefit-cost ratio. Probability analysis is used to estimate the uncertainties in the project calculations. Based on a conservative estimate, the restocking of sandfish is expected to be profitable, although cost-benefit analyses are sensitive to the survival of restocked sandfish and their progeny, and the number of boats fishing for sandfish in the release area.

Economics and Hawaii's Marine Fisheries

This paper reviews economic research conducted on Hawaii's marine fisheries over the past ten years. The fisheries development and fisheries management context for this research is also considered. The paper finds that new approaches are required for marine fisheries research in Hawaii: A wider scope to include other marine resource and coastal zone issues, and increased and closer collaboration between researchers and the fishing community.
