Abstract:: In marine resource management, spatial policy instruments, including Marine Protected Areas, are becoming increasingly important. The economic motivation for spatially explicit policy is that renewable resources generate, in addition to the conventionally recognized incentives to over-harvest in the face of insecure property rights, spatial externalities that distort the spatial distribution...

Abstract:: Ecologists warn that the rapid evolution occurring as a result of high-intensity commercial fishing could have potentially disastrous economic and ecological effects. The evolution of economically relevant life-history traits in fish, which can occur due to the harvesting pressure from commercial fisheries, can irreversibly diminish fisheries yields and ecological services....

Creator:: Steenkamp, Z. D.
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...

Abstract:: Le but de cette communication est de démontrer que le recrutement et le membership au sein d'unités de production qui se consacrent à la pêche côtière ne sont pas uniquement conditionnés par des modifications dans la technologie. Ils s'insèrent aussi dans des chartes cognitives et sociales qui, en plus d'intégrer...

Abstract:: Pacific whiting (Merluccius productus) is one of the most commercially valuable fish species in the Pacific coast groundfish fishery, experiences extreme variability in annual recruitment. This variability causes fluctuations in stock abundance and subsequent catch and economic benefits. This study develops a stochastic bioeconomic model of the Pacific whiting fishery...

Abstract:: Uganda’s fisheries sub-sector is predominantly supported by traditional small-scale fisheries which plays a vital role in food security and livelihoods of at least 5.3 million Ugandans. Nonetheless, this role has not been adequately characterized and quantified. Here, we report part of the work undertaken between June 2010 and December 2013...

Creator:: Schrank, William E.
Abstract:: Fisheries is not the only discipline where models have been used in attempts to fine tune an aspect of the economy. Such fine tuning can prove ineffective because of the uncertainties in the scientific underpinnings of the models and because of the omission of critical elements. In fisheries, the biological...

Creator:: Zhang, Junjie and Smith, Martin D.
Abstract:: This paper proposes a two-stage method to estimate a generalized Gordon-Schaefer model, using heterogeneous fishing data in the logbook. A Cobb-Douglas production function is consistently estimated in the first stage by means of the ‘within period estimator’. A stock index is constructed and used to estimate the logistic growth model...

Abstract:: Stakeholders of the Taal Lake fish cage industry face the challenge of producing fish in a situation of frequent fish kill occurrences, which have been attributed to the deteriorating water quality due to nutrient pollution from fish cages. This study estimates the cost-effectiveness of nutrient pollution reduction options. Fifty operators...
