Although the ocean provides living space for about 97 percent of life on Earth, less than 5 percent of the ocean below the surface has actually been seen, let alone explored. Now, using the geographic information system (GIS), marine scientists are gaining new insights into a once-mysterious world. A technologically...

There is considerable debate in the literature about the usefulness of Marine Protected Areas as fishery management tools. While most economists have found that it is unlikely that marine reserves will improve steady-state yields, some biologists have shown that protected areas have the potential to reduce uncertainty. Most of the...
In agriculture there has been a long history of using a levy or an insurance premium to create mutual funds to mediate economic risks to growers due to environmental variability and quarantine pests. In the United States the federal government, through the USDA, continues to underwrite funds (collected by private...
A principle U.S. fisheries management concern is ensuring compliance with Endangered Species Act requirements to limit incidental takes of listed species to levels which do not result in potential jeopardy to existing population stocks. Part of the risk assessment process involves an analysis of historic takes (bycatch) of ESA-listed species...
Under the reauthorized Magnuson-Stevens Act (MSRA), US fisheries management councils must specify an annual catch limit (ACL) for each managed species and institute accountability measures (AMs) to ensure that actual harvest will not cause the stock to be overfished. While the details of implementation are still being developed, a set...
Many futures contracts for food commodities have been introduced; however, most of them have been withdrawn from the market due to poor liquidity. In this paper, various known success factors for futures contracts with regards to a proposed futures contract for salmon are discussed. Based on the various criteria from...
Great efforts have been made in order to manage the fisheries more sustainably, but so far, most of these efforts have failed. This is putting the welfare of current and future generations at risk. The fishing fleets have catching capacity that well exceeds the rate at which ecosystems can produce...
Marine reserves have increasingly been recognised for their potential to address the pervasive problem of unsustainable harvest of fisheries worldwide. Abalone catch around Stewart Island has been in decline since the turn of the century despite being managed under NZ's quota system. A nested logit model is applied to spatially...
