Creator:: Arnason, Ragnar
Abstract:: When fishers can avoid detection and/or sanctions for violating fisheries management rules, the fisheries enforcement problem becomes substantially more complicated. A number of issues immediately pop up. First, the effectiveness of enforcement effort is reduced. This, ceteris paribus, reduces the optimal enforcement effort. Second, the impact on the fishery of...

Creator:: Arnason, Ragnar
Abstract:: The sustainable yield function is a favoured tool in fisheries policy making. Normally, this function is drawn as a continuous curve in effort-yield space. This means that sustainable yield (harvest) is gradually reduced to zero as fishing effort increases. This, however, does not have to be the case. The sustainable...

Creator:: Arnason, Ragnar
Abstract:: This paper estimates current resource rents being generated in the Icelandic cod fishery and compares them to the maximum sustainable attainable ones. For this purpose a simple aggregative model of the cod fishery is specified and empirically estimated. It is found that in spite of the cod stock being in...

Creator:: Arnason, Ragnar
Abstract:: Weitzman's paper is useful because it provides the fisheries economics profession with a reason to re-examine certain elements of the currently accepted fisheries management theory. As a result, this contribution may lead to a more solid theoretical foundation for fisheries management. This, of course, is the way any science is...

Creator:: Arnason, Ragnar
Abstract:: This paper considers the costs of fisheries management. It starts by reviewing the costs of fisheries management in Iceland, Newfoundland and Norway. The outcome of this study, as well as information from other countries, indicates that fisheries management costs are generally quite substantial relative to the value of landed catch....

Abstract:: The hilsa shad (Tenualosa ilisha) fishery is the largest single species fishery of Bangladesh managed under open access system was chosen for the study. The purpose of the study was to develop optimal policy to assess the optimal exploitation of the fishery. The objective was to maximize the net benefit...

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...

Abstract:: Rising consumer concern over intensive food production issues has resulted in an increase in demand for organic alternatives to a wide variety of foods including fruit and vegetables, meat and poultry. More recently, there has also been considerable interest in the marketing of more environmentally-friendly supplies of fish, including those...

Creator:: Mome, Masud Ara and Arnason, Ragnar
Abstract:: The hilsa shad (Tenualosa ilisha) fishery is by far the largest single species fishery in Bangladesh. In this paper, a simple bio-economic year-class based model is developed to describe the fishery and examine its properties. With the help of this model, the optimum sustainable yield of the fishery is calculated...

Creator:: Heimisson, Asgeir Fridrik, Arnason, Ragnar, and Olafsdottir, Gudrun
Abstract:: Fish farming has grown very rabidly during the past few decades. One component of this expansion is the introduction of new species, previously unknown to most consumers, to world markets. Arctic char, a cold water salmonid, is one of these species. In 1987, the total commercial supply only amounted to...
