There is increasing concern among fisheries scientists and managers over
the ecosystem effects of fisheries exploitation. This concern has been
motivated by several publications inferring that the structure of marine
ecosystems has been dramatically altered by historical patterns of fishing.
Among the most cited studies is the paper by Pauly...
In the 1950s the Pacific sardine collapsed, and the fishery declined from a
historical peak of over 600,000 metric tons in 1936 to less than 100,000
tons after 1951 and was virtually nonexistent for 25 years (1965-90).
Despite this, the landings of sardine predators increased after the sardine
collapse and...
This paper deals with the sustainable management of a renewable resource
based on individual and transferable quotas (ITQs) when agents differ in terms of
harvesting costs or catchability. In a dynamic bio-economic model, we determine
the conditions under which the manager of an ITQ system can achieve sustainability
objectives which...
Employing an experimental approach, we examine whether the efficiency of fishery management
can be achieved under Individual Transferable Quotas regimes. We analyze the situation in
which subjects can choose one from two vessel types: a large-scale or a small-scale. The fixed
cost for the large-scale is higher than that for...
In Japan, common fishery rights are granted by prefectural governor only to local fisheries cooperative associations (FCAs). Coastal resources like abalones are utilized by local fishers as members of FCAs. Fishery rights are deemed to be real rights and any person encroaching upon this right is subject to fine. Therefore,...
The US Magnuson-Stevens Act authorizes the use of onboard observers to
monitor commercial fisheries catch and bycatch (PFMC 2003). A question
of concern in implementing an observer program is that of the appropriate
level of observer coverage. Current practice varies by fishery; for example,
the California-Oregon drift gillnet fishery for...
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...
The paper explores to what extent escaped farmed salmon from fish farms affect the willingness-to-pay for recreational fishing of Atlantic salmon in Norwegian rivers. The aim is to quantify the potential externality from escaped farmed species working through the demand for the natural stock of congeners. While the biological and...
It is often taken for granted that taxation of rents is economically nondistortive. In certain areas of natural resource use, e.g. oil extraction and fisheries, this nondistortion principle has been used to justify taxation of what is regarded as resource rents. This paper challenges the view that such taxation is...
