    An analysis of the effects of institutional, biological and economic forces on the Virginia oyster fishery
    March, Richard Alan (Virginia Polytechnic Institute and State University, 1986)
    The Virginia oyster industry changed markedly in the period between 1950 and the present. This change has been the result of a variety of forces which can be conveniently classified as economic, biological and institutional. In general, biological forces initiated a series of changes in the fishery which have had economic impacts and impacts on the institutional structure of the fishery. The biological forces have had a much more severe impact on the seed-planting, or private grounds, sector than on the public grounds sector. The dependence of the seed planting sector on public seed beds and the different regulatory regimes applicable to the public and private grounds makes it difficult to draw firm conclusions on the relative merits of alternative tenure structures. The magnitudes of economic, biological and public policy forces as contributing factors to the decline of the oyster fishery are estimated and it is concluded that the biological forces have played the dominant role in the decline of the Virginia oyster fishery. It is suggested that attention be focused on the physical and management inputs to the production of oysters and on methods for bringing forth an appropriate resource mix. It is argued that either a predominantly private grounds fishery, a predominantly public grounds ‘' fishery, with appropriate institutional modifications to allow efficient harvest technologies to be used without threatening the viability of the resource base, or a mixed tenure system could be used and with appropriate management could result in substantial revitalization of the Virginia oyster industry. However, because of the biological changes which have occurred, management, whether public or private, takes on a much more important role in determining the future of the Virginia oyster fishery.
