Un Etat moderne signifie-t-il une pêche moderne? l'exemple de la Martinique

Creator:: Failler, Pierre
Abstract:: La pêcherie martiniquaise se trouve aujourd'hui dans une situation paradoxale : d'un côte elle se veut résolument moderne de par 1) les embarcations et des outils de production de plus en plus sophistiqués (coques rapides sur-motorisées, GPS, etc.) que les pêcheurs acquièrent a grands frais; de l'autre, elle reste séculaire...

Policy Conundrum: Restoring Wild Salmon to the Pacific Northwest

Creator:: Lackey, Robert T.
Abstract:: Restoring wild salmon runs to the Pacific Northwest is technically challenging, politically nasty, and socially divisive. Past restoration efforts have been largely unsuccessful. Society’s failure to reverse the continuing decline of wild salmon has the characteristics of a policy conundrum: nearly everyone supports, abstractly at least, restoring salmon runs; considerable...

The death rattle of open access and the advent of property rights regimes in fisheries

Creator:: Christy, Francis T.
Abstract:: In considering fisheries regulation in the next decade, I make a concluding point that may become a major theme. This is that individual permanent catch quotas of a regulator-determined TAC are only a stage in the development of management from licensing to private rights (Scott 1989). The condition of open...
