Pacific sardine (Sardinops sagax), which is a transboundary resource
targeted by Mexican, U.S. and Canadian fisheries, has exhibited extreme
decadal variability in its abundance and geographic distribution
corresponding to water temperature regime shifts within the California
Current Ecosystem. Our study develops a three-agent bioeconomic
framework that incorporates environmental effects on...
The UN Law of the Sea of 1982 assigned rights and responsibilities to the
fishery resources within 200 nautical miles of the coast (i.e.,the Exclusive
Economic Zones: EEZs) to the adjacent maritime countries. A key
responsibility is the requirement that these countries manage their marine
living resources sustainably through time...
The Patagonian marine ecosystem is one of the most productive
ecosystems in the world, with important commercial shared/straddling
stocks. One of the highest mobility resources is the Argentine shortfin
squid (Illex argentinus). Its distribution is limited to the area of influence of
the warm-cold waters of sub-Antarctic origin, particularly of...
Some attempts have been made in the past to provide estimates of the value
of global fisheries. For example, catch values from marine fisheries have
been reported by the FAO (2008) and Sumaila et al. (2007). The World
Bank (2008) estimated that current economic rent from the worlds fisheries
is...
I begin my talk by identifying the fish species that inhabit the California
Current Large Marine ecosystem (CCLME). Next, I categorize these
species into predator-prey and forage and non-forage fishes. I then present
the current catches, landed values, payment to labour (wages), capital
(profit) and payment to the resource owners...
Recent articles in the multidisciplinary fisheries literature have been critical
of fisheries economics concepts and literature. For example, a paper by
Bromley (2009) entitled Abdicating Responsibility: The Deceits of
Fisheries Policy: Fisheries 34(6):280-302, provides a critical review of
fisheries economics. I explore the main issues raised in this paper and...
Fisheries economics theory suggests that weak fishery management
institutions, such as an open access regime, provide the motivation for
fishers to act as if they have infinite discount rates. This theory has serious
implications for the management of small-scale reef based fisheries in
developing countries, many of which are open...
We combine information from several global fisheries databases including
those from the Sea Around Us Project (www.seaaroundus.org) and the
Fisheries Economics Research Unit (http://feru.org) to project the future
potential gains in human welfare under the assumption that (i) global
fisheries continue the current declining trend observed over the last several...
