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...

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...

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...

Abstract:: Shrimp farming in Iran is one of the fast growing segments of the economy. In 1994, around 1% of Iranian shrimp production was farmed and by 2003 the share of shrimp farming increased to 60%. In spite of the fact that shrimp culture had relatively rapid growth in last decade,...

Abstract:: Global aquaculture production increased with an average rate of 10% per year since 1990 and 90% of aquaculture production comes from developing countries thus providing livelihood and income especially to marginal groups who have limited access to resources such as agricultural land and financial capital.
