The introduction of Individual Transferable Quota (ITQ) fisheries management is controversial as it
typically results in fewer active vessels, fewer vessel jobs, and the remaining vessel crew earning a lower
share of vessel revenues with capital interests, including the new interest "quota ownership", increasing
their revenue share. However, the move...
The British Columbia Seafood industry has witnessed fundamental and unprecedented changes to its business environment since the early 1990's. These changes include worldwide phenomena such as changes in consumer tastes and world economies, globalization, the growth of aquaculture, the growing and influential environmental movement, and the need for greater traceability...
Chinook salmon returns to the Columbia River basin have declined due to impacts of a growing human population, despite significant mitigation expenditures. Consequently, fisheries managers have become focused on recovery and long-term viability of at-risk populations. A viable population depends, in part, on the connectivity and quality of diverse habitat...
The basaltic landscapes of the Oregon High Cascades form a natural laboratory for examining how geologic setting and history influence groundwater flowpaths, streamflow sensitivity to climate, and landscape evolution. In the High Cascades, highly permeable young basaltic lavas form extensive aquifers. These aquifers are the dominant sources of summer streamflow...
A hierarchical classification system of Iceland's
watersheds and rivers is presented. The classification
is based on Iceland's substrate, climate, water, biota,
and human cultural influences. The geological formations
of Iceland are very different in character depending on
their age and formation history. Three major types of
formations occur: Tertiary, Plio-Pleistocene,...
Using a two-stage harvesting game, I model the political and economic incentives to overfish in a regulated, restricted access common property fishery with income supplements. As variable fishing effort is regulated and effort caps appear to be binding, I argue that social choice of political lobbying effort becomes the principal...
Marine reserves are known to directly replenish overfished species. However, the
community-wide effects of reserves are less clear. I examined the community of coralreef
fishes in a large, fully protected marine reserve in The Bahamas: the Exuma Cays
Land and Sea Park. Visual-transect surveys provided estimates and comparisons of the...
Many Fraser River sockeye salmon stocks show large cycles in abundance from year to year, but the causes of these
cycles are not clear. As a result, these stocks have historically been managed under the hypothesis of cyclic dominance,
i.e., maintaining the cyclic behaviour of the stocks. Biological studies and...
Changes in ownership of limited entry permits by “local” residents of the region where a fishery occurs
may have significant economic and social implications for fishery-dependent regions. This paper
examines changes in local permit ownership in Alaska salmon fisheries, for which a long-term decline in
rural local permit ownership is...
