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:: This paper deals with the application of a dynamic model, combining Transaction Cost Economics (TCE) and Penrose’s theory of the growth of firms, under the New Institutional Economics (NIE) terms, to analyze and manage the “Agribusiness Innovation System” (SIE) coordinated by an agricultural research-development (R&D) organization in Brazil – Embrapa....

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...

Abstract:: This paper analyzes spatial patterns of exploitation in the California sea urchin fishery using two different econometric approaches: a Poisson/SUR model of monthly observations and a micro-level Nested Logit model of individual harvester daily decisions. Each model is used to simulate the spatial distribution of fishing effort. The models are...

Abstract:: The purpose of this study is aimed at developing a simple bioeconomic model of the Namibian rock lobster fishery, with the main objective being to incorporate economics into fisheries management in order to estimate the potential economic benefits that could accrue to the fishery given efficient management. The complex nature...

Creator:: Cairns, Robert D.
Abstract:: The theory of extensions to the national accounts is expressed in models in which wealth is being explicitly maximized. For the fishery, the central issue is such valuation when the policy being followed is inefficient. We begin the task of making such valuations for commercial products of a fishery. Capacity...

Abstract:: Many Fraser River sockeye salmon stocks show large cycles in abundance from year to year, but the causes of these cycles are not clear. As a result, these stocks have historically been managed under the hypothesis of cyclic dominance, i.e., maintaining the cyclic behaviour of the stocks. Biological studies and...

Creator:: Huang, Ling, Nichols, Lauren A. B., Craig, J. Kevin, and Smith, Martin D.
Abstract:: While environmental stressors such as hypoxia (low dissolved oxygen) are perceived as a threat to the productivity of coastal ecosystems, policy makers have little information about the economic consequences for fisheries. Prior studies based on data aggregated at relatively large spatial (e.g.,1000s km) and temporal (e.g., annual) scales have typically...

Abstract:: While the focus of Lake Victoria Nile-perch fishery is to serve the global market and tilapia is mainly for domestic market in Tanzania; Dagaa has a great potential for small scale trade in regional markets. In 2006 a survey was conducted to assess the regional fish marketing channel for the...

Abstract:: This paper analyzes optimal fishery management in the presence of an endangered predator that competes with humans for a commercially viable prey. Because traditional predator controls are not possible when the predator is endangered, we focus on harvest effort controls over the prey’s habitat as a means to maintain the...
