Annual recruitment of the New Zealand longfin eel (Anguilla dieffenbachii) has decreased by around 75 percent since heavy levels of commercial fishing began in the early 1970s. Given the unsustainability of existing regulatory policy, a deterministic multiple-cohort bioeconomic model is developed and applied to this system to gain insight into...
From merely being cod liver oil taken for vitamins A and D, fish oils have moved into the center stage of fatty acids in nutrition. The analytical work starting in 1950 provided the means to recognize the long-chain and truly essential n-3 polyunsaturated fatty acids vital for retinal, neurological and...
Stated preference (SP) methods such as contingent valuation and choice experiments are often used to estimate values associated with marine and coastal ecosystem services. However, applications do not always apply best practices, leading to questions regarding the validity and relevance of welfare estimates. This presentation outlines contemporary best-practice recommendations for...
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 theory of extensions to the national accounts is expressed in models in which wealth is being explicitly maximized. For the fishery, the central issue is such valuation when the policy being followed is inefficient. We begin the task of making such valuations for commercial products of a fishery. Capacity...

Frank Asche is professor in the Department of Economics at the University of Stavanger, Norway. Funding for this project was provided by...
Enhancement of British-Columbia-to-Alaska Transboundary Rivers is a vast potential prize to all concerned. However, despite funding commitments in the Pacific Salmon Treaty, that program is at great risk of always being more potential than real. The cooperation needed to make this program work has been and continues to be grievously...
Increased attention is being given to the promise of co-management as a means of achieving sustainable
fish stocks while at the same time providing benefits to those dependent on the fishery. At the same time,
the view that co-management represents a continuum between state or user control is being replaced...
Since 1979, the United States has been collecting data on marine recreational angling with the Marine Recreational Fisheries Statistical Survey (MRFSS). To enable the estimation of travel cost models of recreational demand the base MRFSS survey has been amended to include necessary data elements. Additionally, data is collected that will...
The saltwater aquarium hobby has increased dramatically in the last decade due to improvements in the technologies and knowledge needed to sustain mini-reef ecosystems. With this increased demand comes increased pressure on natural reef ecosystems that supply the vast majority of the live organisms for the commercial market. To combat...
