Abstract:: In this study, we tried to develop a theoretical framework based on the Schaefer model and establish bioeconometric models to estimate the index of fishery resources using cross-country macro data. The characteristics of our model are that we consider the effect of natural fluctuations of fishery resources over time (in...

Creator:: Seidel-Lass, Linda
Abstract:: The security of world fish supply from wild fisheries and from aquaculture is an increasing concern due to dwindling yields from wild catch and undesirable ecological impacts of aquaculture. The extent to which aquaculture can substitute for fish from wild catch will depend on the productivity of aquaculture, which in...

Creator:: Mikkelsen, Eirik
Abstract:: Assuming externalities from aquaculture to fisheries, we use a Verhulst-Schaefer model of fish population-dynamics and production, coupled with an aquaculture production model, to investigate effects on open-access and rent-maximising fisheries. Externalities are modelled by letting carrying capacity, intrinsic growth rate or catchability coefficient in the fishery depend on aquaculture production....

Creator:: Perez Agundez, José A. and Mongruel, Rémi
Abstract:: This paper sets out an evaluation of profitability differentials within shellfish farming activities of the Mont-Saint-Michel Bay. The objective is to examine whether profitability differentials have consequences in terms of economic dynamics and of management arrangements. The paper divides into four parts. The first part presents a retrospective analysis of...

Abstract:: The advent of scientific shrimp farming in India during 1990-91 was a turning point of shrimp production in the country. Though scientific shrimp farming system renders higher level of production than the existing traditional farming system, it is subject to certain criticisms especially for generating negative environmental externalities. The conversion...

Creator:: Mohammad-Rezaei, Rassul
Abstract:: In natural resource economics, we sometimes observe a situation in which producers and consumers have direct access to the factors of production or can use some consumable products with little or no transformation. These goods are commonly referred to as “gifts of nature”. A factor of production is considered a...

Creator:: Pyo, Hee-Dong and Lee, Sang-Go
Abstract:: The success or failure of aquaculture heavily depends on how effectively to manage aquatic animal diseases. In order to analyze the economic effects of aquatic animal disease control, the specific factors and magnitudes of benefits and costs are identified with and without the proposed project for the disease control. These...

Abstract:: A bio-economic model, based on Faustmann rotation, was developed to analyze the relevance of removing thinning activities which are part of the dominant technology used in blue mussel production in Canada. Removing these density control activities (thinning) seemed a profitable option to producers. It was thought that this collector line...

Creator:: Fell, Harrison
Abstract:: Economists have generated numerous studies analyzing how a move to rights-based fishery management from open-access management affects fish harvesters' behavior. Conversely, the impacts that such a change in management can have on fish processors has received relatively little attention. This paper presents a simple two-product processor supply model to show...

Abstract:: Wholesale demand systems for live reef food fish in Hong Kong are analysed using the Linear Approximate Almost Ideal Demand System (LA/AIDS). Results suggest that price elasticities of demand are inelastic, with relatively high-valued species exhibiting greater elasticity than relatively low-valued species. Cross price elasticities are negative suggesting that different...
