Modeling The Role Of No-Take Marine Reserves In Fisheries Management, Deidre F. Gilbert
Modeling The Role Of No-Take Marine Reserves In Fisheries Management, Deidre F. Gilbert
Electronic Theses and Dissertations
In recent years there has been increasing interest in the potential of no-take marine reserves to benefit fisheries management. Scientific reviews have shown that reserves often lead to substantial increases in the density, biomass, size and diversity of marine fishes inside their boundaries. However, little empirical work has been done to determine the effect of reserves on the fisheries outside their boundaries, such as potential changes in yield, size of fleet, or variability in catch. In order to explore the interaction between the biological growth and dispersion processes of the harvested stock and the changing economic incentives of harvesters created …
Numerical Wave Simulations On Different Oceanic Scales, Khalid M. Zubier
Numerical Wave Simulations On Different Oceanic Scales, Khalid M. Zubier
Electronic Theses and Dissertations
In practical applications, numerical wave models are used as reliable tools to provide near future wave predictions and wave climatology for specific region. Obviously models first should go through extensive validation/verification procedures. Once validated, models can be used in scientific applications to investigate methods for improving performance and to develop better understanding of wave associated physical mechanisms and their interactions in specific field experiments. Two wave transformation models, SWAN and CGWAVE, are used to simulate wave conditions at the Field Research Facility, Duck (North Carolina). The motivation is to examine how well these models reproduce observations and to determine the …
Marine Protected Areas In The Gulf Of Maine: Policy For A Common Resource, Carolyn F. Skinder
Marine Protected Areas In The Gulf Of Maine: Policy For A Common Resource, Carolyn F. Skinder
Electronic Theses and Dissertations
In the wake of 25 years of unsuccessful single-fisheries management in the Gulf of Maine, there has been growing support for reform. Ecosystem management has been proposed as one alternative, but the information needed to manage whole ecosystems is greatly lacking. Implementing fully-protected marine protected areas (MPAs) is one way to preserve habitat while at the same time acquiring data for future ecosystem management. Under the current institutional arrangement in the Gulf, engineering agreement for MPAs is difficult due to the differing goals of varied user groups. The situation is reflective of a common property resource problem in that there …
