Creator:: Andreasson, Stefan and Flaaten, Ola
Abstract:: Gear technologists have, in recent years, developed rigid sorting grids, Sort-X, in bottom trawls, to improve the size selectivity of this type of gear. Experiments with the Sort-X system in the aft sections of trawls were carried out aboard Norwegian and Russian trawlers along the coast of Northern Norway and...

Abstract:: Game-theoretic fisheries models typically consider cases where some n countries harvest a common fish stock x. For this common resource they attempt to achieve an agreement that would be beneficial to all countries. The present paper considers cases where the countries may be involved in several coexisting agreements. We identify...

Abstract:: The study investigated fresh fish characteristics that determine consumers' preference for fresh fish in rural and urban households. Primary data were collected from a total of 192 fresh fish consumers using multi-stage sampling procedure. The data were analyzed using descriptive statistics, regression analysis and Relative Attribute Model (RAM). The results...

Abstract:: 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...

Abstract:: Consumer-facing traceability systems are emerging in the global seafood sector as a way for companies to reduce their reputational risk, access certain markets, and to generally communicate production practices to downstream actors. What are the characteristics of these systems, what benefits do they bring to different value chain actors, and...

Abstract:: As fisheries management becomes more collaborative by seeking input and involvement from stakeholders, it is important to understand and address the diversity of those stakeholders. Gulf Coast fisheries communities include diverse racial and ethnic groups, particularly a large number of Vietnamese Americans involved in all aspects of the seafood industry....

Abstract:: The potential economic impact of a fully developed mariculture industry in Alaska is not well understood by industry or policy makers. It is also not entirely clear what is needed to move from Alaska’s current micro industry (approximately $500,000 in annual sales) to a fully developed industry. In general, the...

Abstract:: Several factors currently threaten blue crab (Callinectes sapidus) in the Chesapeake Bay. In addition to poor water quality, degraded habitat, and shifting environmental conditions, derelict gear has recently been recognized as a significant source of mortality for this economically and culturally significant species. From 2008 through 2014, commercial watermen in...

Abstract:: The main instrument used in fishery management is the total allowable catch (TAC). Fishery management often fails because TACs are set too high and do not sufficiently restrict fisheries. The question we address in this paper is why do decision makers choose inefficiently high TACs? Our approach is to model...

Abstract:: This paper examines the tradeoffs between the production of crops and habitat for juvenile salmon, through flood events, on the Yolo Bypass floodplain. I investigate how changes in the fishery management institution affect the economic returns to fish habitat. To understand how habitat provision affects the economic surplus of the...
