In industries that are characterized by frequent innovations and high productivity growth, substantial variation in both produced quantity and input use may occur and lead to increased cost. As both excessive input use and misallocation of inputs are costly for the producer, firm-specific measures of both technical and allocative inefficiency...
In many situation, fishing activity adversely impacts the state of the marine ecosystem, impacts which feed back to affect fish stocks. Some ecosystems appear to have multiple equilibria and exhibit hysteresis, whereby they can become stuck in low productivity states. We show how adding ecosystem dynamics to a classic fisheries...
Age and size at maturity are key life-history traits in a fish stock. At the individual level, age and size at maturity affect fecundity, growth and survival. At the population level these factors interact to affect the age and size distribution, the population dynamics and the productivity of the stock....
Over the last four decades, the aquaculture sector especially in developing countries has experienced dramatic growth. The increase in aquaculture production is a combination of area expansion and technological change (enhanced strains, input of feed and fertilizer, and improved management). One example of such technological change is the selective breeding...
When attempting to mitigate the environmental impacts of a fishery there are typically multiple criteria
against which the performance of any measures can be assessed. If the gains are non-commercial (i.e.
non-market) in nature, formally determining how well measures perform becomes more difficult. This study applies the analytic hierarchy process...
Our paper aims to study the image of the European fisheries sector, as perceived by European citizens. To
our knowledge, no approach has focused on the perceived impact of fishing on the halieutic resources. More precisely, we seek to analyze the perceived impact on the marine environment of fishing activities...
After decades of decline, real salmon prices paid to California fishermen have rebounded in the past few years. This recent price recovery is probably due in part to reduced availability of fresh salmon in local
markets, but anecdotal evidence suggests increased product differentiation by consumers is also an important part...
The impacts of fishery management actions on shore-based fishing and fishing related infrastructure have received increased attention in the Northeast region of the United States. However, analyses of these impacts have generally focused on directly affected fisheries, ignoring changes in other fisheries and on other sea and land-based activities. Developing...
Increasingly fishery managers are expected to take an ecosystem approach to fisheries management that accounts for the interrelationships of target species as well as non-target species and habitat. Fishery managers would benefit from coupled ecological-economic models that includes both the human and ecological aspects of the fishery and incorporates them...
