Abstract:: Reducing harvesting capacity in fisheries is of international importance. In 1999, member nations of the United Nations Food and Agricultural Organization (FAO) agreed to an International Plan of Action to reduce fishing capacity. Two initial concerns were the acceptance of a workable definition of capacity and the development of methods...

Creator:: Fare, Rolf, Grosskopf, Shawna, Kirkley, James L., and Squires, Dale
Abstract:: The Sustainable Fisheries Act (SFA) and Code of Conduct for Responsible Fisheries Management require restoration of fishery resources and a matching of capacity to desired resource levels. There is, thus, a need to reduce harvesting capacity throughout many of the fisheries of the world. Yet, even the term capacity is...

Creator:: Kirkley, James, Walden, John, and Färe, Rolf
Abstract:: Interest in ecosystem-based management or the ecosystem-based approach to fisheries management has rapidly increased on a global basis. Most options for ecosystem-based management have emphasized some type of biological and natural conservation or non-use, and minimal attention has been given to assessing the social and economic ramifications of ecosystem-based management....

Creator:: Groeneveld, Rolf and Poos, Jan-Jaap
Abstract:: Discard rates in marine fisheries have been estimated at more than 80% for some individual fisheries, with an average global discard rate of 8%. Discarding of catch can be problematic for three main reasons: (1) in the absence of accurate and precise discards estimates, unreliable catch data distort estimation of...

Creator:: Arnason, Ragnar and Willmann, Rolf
Abstract:: According to conventional economic wisdom the economically more efficient technology will always outcompete the less efficient. This hypothesis has usually been taken to hold for the exploitation of common pool renewable natural resources such as fish stocks. This paper claims that, while this is not necessarily false, it may be...

Creator:: Klepper, Rainer and Lasch, Rolf
Abstract:: The very restrictive quotas of cod in the Baltic Sea are a strong force for searching alternatives. Since 1996 for instance, the cod quota for the German fishery was reduced from 22 000 t to 13 000 t in the year 2001. And further cuts took place in 2002. However,...

Creator:: Bosma, Roel, Groeneveld, Rolf, and Hakim, Lugas
Abstract:: Large areas along Java’s north coast are threatened by subsidence and abrasion. Subsidence is even faster than sea level rise. Although forbidden by law, farmers have cleared the mangrove forest almost up to the coastline, thus reducing sedimentation and increasing exposure to coastal abrasion. Four interventions are needed: reduce groundwater'...

Creator:: Guettler, Stefan and Mueller, Rolf A. E.
Abstract:: Aquaculture is increasingly important for the future supply of fish because of steadily increasing demand while supply from fisheries is stagnating. In the EU aquaculture production has grown strongly in some countries, such as Spain and Greece, but was flat at a low level in others, such as in Germany,...

Abstract:: Indonesian tuna fisheries are complex due to variation in the scale of fleet in the fisheries, their multi-species nature and problems with data collection. Moreover, like many developing-country fisheries, their management needs to take into account many other goals besides rents maximization, such as the distribution of rents and the...

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...
