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...
The typical coho salmon life history has been characterized by juvenile fish that spend their entire first year in freshwater habitats before migrating into estuaries as smolts. However, reports of early migrating coho fry (age 0), including migration downstream to estuarine habitats, date back to the 1960s. Until a few...
Project CROOS, Collaborative Research on Oregon Ocean Salmon, is a unique partnership of scientists and commercial fishermen that combines catch location data with stock assignments obtained from genetic micro-satellite analysis to investigate the distribution of Oregon Chinook across multiple spatial scales. Using catch data collected by collaborating Oregon troll fishermen,...

Chinook salmon: fish, people and the fishery
The bycatch problem has remained troubling and persistent, even in
fisheries that have rationalized their target fisheries. The Alaskan Pollock
fishery is an example of a fishery struggling to contain the bycatch of
salmon in spite of a transformation of incentives associated with a
harvester coop system in the target...
The West Coast salmon fishery presents several complexities that have received little attention in the fisheries economics literature. Two of those complexities are reviewed and analyzed in this dissertation. The first, salmon fishermen participate in alternative fisheries within a season demonstrating a complex switching behavior between different species. Second, the...
Bycatch is repeatedly noted as a primary problem of fisheries management
and as the foremost negative impact of commercial fishing. In the Bering
Sea pollock fishery, salmon bycatch reduction measures have included gear
modifications but have principally consisted of area closures. Bycatch
levels of chum and Chinook salmon have risen...
After salmon bycatch levels reached record levels in 2006 and 2007 in the
Bering Sea pollock fishery, the North Pacific Fishery Management Council
(NPFMC) began consideration of a hard cap that would close the fishery if
it were reached. The NPFMC asked for input from economists at the
National Marine...
Releasing hatchery reared salmon and steelhead to supplement threatened and endangered populations is a widely used conservation tool. One issue with this strategy is hatchery fish have lower reproductive fitness than wild fish when spawning in the wild. One of the drivers of fitness loss in steelhead is adaptation to...
