Climate and marine ecosystem research informs us that marine fish resources would come under increasing stress over the course of the 21st century as global climate change, ocean acidification and de-oxygenation combine with other stresses on the ocean, including heavy fishing pressure and marine pollution, to change the primary productivity...
Collaborative management is essential in fisheries with multiple users, where different fishing groups compete to exploit a shared stock, often using unsustainable practices. This is the case in the Coral Triangle, an ecosystem increasingly coveted by conservation organizations for its high biodiversity, and heavily exploited by fishing groups from the...
We present a bottom-up analysis of the proportion of global marine fisheries subsidies to small-scale fisheries (SSF). Using existing data, we split the reported national subsidy amounts into the fraction that goes to small- compared to large-scale fishing sectors. Results reveal a major imbalance in subsidy distribution, with SSF receiving...
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...
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...
Women's contributions to fisheries are often overlooked in fisheries management, economic analyses, and consequently, in policy decisions. Fortunately, women's contributions are gaining recognition despite a lack of quantitative data describing the scope and scale of their participation in the sector. While there are numerous studies describing the role of women...
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...
Salmon aquaculture generates good output (i.e. salmon) and bad output (e.g., pollution). A joint production function approach is applied to model both outputs simultaneously. Two environmental production
technologies are proposed, namely, regulated and unregulated technologies. Two production function models with different mapping rules in the analysis are used. Pollution abatement...
Even in the absence of commercial fishing, Coho salmon (Onchorhynchus kisutch) originating from the Interior Fraser River (IFR) watershed have yet to recover from the low returns experienced since 1992. Coho are in a low productivity regime in which the number of recruits per spawner (R/S) averages around one, coupled...
This paper is drawn from a project report that was sponsored by the United Nations through the Benguela Current Large Marine Ecosystem Programme. We analyze the economics of fishery management in the Benguela Current Large Marine Ecosystem (BCLME), reviewing the case for and against regional co-operation in managing the BCLME....
