The implementation of ecosystem-based fisheries management (EBFM) requires the development of new analytic tools to integrate environmental, ecological, and socio-economic data from various sources; to capture explicit interactions among ecosystem components; and to simulate and evaluate the effects of alternative management options. We are developing a computable general equilibrium (CGE)...
The activity of commercial whaling is contentious, drawing the ire of animal rights and conservation groups who threaten boycotts of whaling nations' products. Whaling also has opportunity costs: in addition to existence value, whales provide nonextractive use values, i.e. whale watching. On the other hand, proponents of whaling argue many...
Many experts have argued that the traditional management of commercial fish stocks as single-species is short-sighted, wasteful, and ineffective. Ecosystem-based fisheries management (EBFM) now is being promoted as a potential solution to the problem. While much attention has been directed recently at the potential benefits of implementing EBFM for commercial...
In many estuarine and ocean areas, aquaculture is seen as an alternative to traditional commercial fish harvesting practices. A significant problem hindering the emergence or the continuing growth of aquaculture in many areas is the conflict that arises among it and other competing ocean uses. Real world examples include the...
We present the outlines of an integrated economic-ecological framework
designed to help assess the implementation of the ecosystem-based
management (EBM) of fisheries in New England. We develop the
framework by linking a computable general equilibrium (CGE) model of a
coastal economy to a bottom-up model of a marine food web...
Coastal and marine spatial planning (CMSP) is a process for improving the management of ocean resources in order to promote their sustainable development. One of the most challenging spatial planning issues in New England now concerns the siting of offshore renewable energy facilities, mainly wind farms. Commercial fishermen are among...
The upper Eocene to lower Oligocene Oswald West mudstone is
the oldest formation (informal) in the Green Mountain-Young's
River area. This 1,663 meter thick hemipelagic sequence was deposited
in a low-energy lower to upper slope environment in the Coast
Range forearc basin. The formation ranges from the late Narizian
to...

lation supports the Beeson et al. (1979) hypothesis that
Ecosystem based fishery management has moved beyond rhetorical statements calling for a more holistic approach to resource management, to implementing decisions on resource use that are compatible with goals of maintaining ecosystem health and resilience. Coupled economic-ecological models are a primary tool for informing these decisions. Recognizing the importance of...
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....
