Creator:: Tomberlin, David
Abstract:: When weak and strong fish stocks are caught in the same fishery, managing for the protection of the weak stock may result in foregone economic benefits from harvest of the strong stock, while managing for the strong stock may result in overfishing of the weak stock. A particular complication arises...

Creator:: Abbott, Joshua and Wilen, James
Abstract:: A canvass of the resource economics literature of the last thirty years yields a limited number of applications of economic theory to the problems of recreational fishing. This neglect may be linked to the short shrift given to the control of recreational fisheries (relative to commercial fisheries) by fisheries managers...

Abstract:: Stock assessment techniques currently used in the United States are extremely costly to implement, involve significant data requirements, and are inaccessible to all but a few stock assessment scientists. A systematic decrease in fishery yields and the designation of several species as overfished on the west coast of the United...

Abstract:: This paper discusses the use of resource assessment surveys as the basis for effective fisheries management drawing on the resource assessment survey of the Arabian Sea coast of Oman. This survey, completed in 2009, has been undertaken in the context of the primary aim of the Oman Ministry of Fisheries...

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:: This study proposes three methods for technical efficiency (TE) estimation using three different fish stock proxy measures while applying the stochastic production frontier (SPF) approach. We apply these methods to two Vietnamese offshore fisheries, gillnet and hand-line, for which measures of stock abundance are unavailable. Based on the assumption of...

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...

Abstract:: The coastal ecosystem of the Pearl River Estuary (PRE) has been overfished and received a high level of combined pollution in the past decades. The fisheries stock assessments have shown a declining population and have led to a number of management measures, including fishing moratorium. This study evaluated the effect...

Abstract:: Structural time series methods are applied to modeling endogenous fishing effort in the German North Sea shrimp fishery. The effects on fishing effort of shrimp price, catch per unit effort and environmental variation are examined. Preliminary results suggest that fishing firms do not respond much to price changes but they...
