Riparian areas in the Pacific Northwest have traditionally been a source of natural resources, such as timber and grazing, and have been used as transportation corridors and homestead sites. A primary impact of use has been the removal of riparian trees, the crowns and roots of which provide shade and...
A serious impediment blocks advancement of individual transferable quota (ITQ) policy in the United States, particularly in North Pacific fisheries being considered for ITQ management. The traditional ITQ design, that allocates rights to only the harvesting sector, unintentionally expropriates wealth/property interests from the co-dependent-processing sector. This regulatory expropriation is a...
The state of the world at the beginning of 21 century is terribly bad from all points of views such as environment, food supply, resources, economy and security essential for human survival. Our civilization based on technological development and mass consumption has been using up all resources on land and...
Fisheries management has been carried out on the assumption that a fish population is in equilibrium with the fishing effort under the average environmental conditions and hence there must be a maximum sustainable yield (MSY). However, since the simultaneous rise and fall of the interdecadal and global scale of sardine...
The inclusion of ecosystem considerations in fisheries management implies two changes with extensive institutional repercussions: the uncertainties about states and outcomes rise dramatically and a multiplicity of new stakeholders, interests and objectives must be accommodated in the management institutions. The first change may potentially add immense costs to the management...
There is increasing awareness of and concern about the actual and potential adverse effects of fishing on the aquatic environment. New Zealand, like many other countries, has developed a range of initiatives to address specific issues related to the effects of fishing, including establishing marine reserves, fishing method restrictions, observer...
As the British Columbia salmon fishery developed, the Canadian government, with constitutional responsibility for the resource, faced a number of critical turning points in management policy. In early years, partly for expediency, the allocation of fishing privileges often resulted in efficient levels of effort but little attempt was made to...
Setting aside the traditional simplistic “tragedy of the commons” notion, fisheries crises observed in the Northern Atlantic may be seen as the result of “mismatches” in the decision making process. The collapse of two fisheries, Atlantic Cod (Gadus morhua) in Canada and European Hake (Merluccius merluccius) in Europe, illustrate the...
Norway has for years managed its coastal fisheries through a regime that for all practical purposes has acted as open access, that is, open for bona fide fishers. The trawling sector was closed already in the 1930s, and the large offshore fleet was regulated through limited entry licensing from the...
