Strategies for increasing production of goods from working and natural systems have raised concerns that the diversity of species on which these services depend may be eroding. This loss of natural capital threatens to homogenize global food supplies and compromise the stability of human welfare. We assess the trade-off between...
Fishers exploit populations that are heterogeneously distributed in space and time without full knowledge of species distributions and with fishing gear that is not fully selective. The ability to change catch composition is limited by species mix at a particular location and time and the capture characteristics of the fishing...
Catch shares are being increasingly adopted worldwide to halt overfishing and improve ecosystem outcomes. Rights-based fisheries management generates economic efficiency, and fishers with a financial stake in the fisheries are believed to have the incentive to become ecological stewards. However, the empirical evidence shows no significant impact of catch share...
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...
Lake Michigan is the only Great Lake that supports an economically viable salmonid population, but a collapse may be on the horizon. Biomass of Chinook Salmon, the most popular sportfish in the region, decreased by 70 percent between 2013 and 2015. The decline is thought to be irreversible. Managers must...
Almost all recent empirical literatures that study the subjective wellbeing of fishers lack of relevant control as they are only based on surveys among fishers. Therefore, they cannot really answer whether being a fisher generate higher or lower life satisfaction, after controlling for other aspects of life. This study is...
In this paper we discuss dynamic adjustment paths towards economic optimal steady-state equilibrium in a fishery where two species interact through a traditional predator-prey relation. We set-up a general bio-economic predator-prey model based on the assumption that fishing effort is a public input applied when exploiting the fish stocks. By...
There are a range of smaller-scale fish farms operating in Ghana producing mainly tilapia and catfish based on extensive (stocking of small reserviours), intensive and semi-intensive (earthen ponds & tanks) techniques. Aquaculture production in Ghana plays a significant role in the economic development of livelihoods of fish farmers and contributes...

The status of fishing industry participants and fishing communities is an increasingly important consideration in marine ecosystem models and in fisheries management. Metrics that reliably measure economic, health, and other dimensions of human well-being are required to analyze the impacts of changes in marine ecosystems and policy. To date, most...
Feedbacks between the ecosystem and the economy are important to consider when measuring impacts from a disturbance but are often missed in representations of the economy and the food web. Moreover, regional general equilibrium models often focus on how humans respond to ecological changes and do not consider that in...
Fisheries products are the worlds most widely traded foods. Despite the fact that global demand for fish and fishery products continues to rise every year, fish export from the developing world have faced many limitation from non-conformity with international standards to inadequate product certification. As international fisheries trade grows, governments,...
Managing internationally-shared fish stocks, those that migrate from one country’s coast to another is incredibly difficult and requires international cooperation. The International Commission for the Conservation of Atlantic Tunas (ICCAT) is the regulatory body responsible for managing tuna and tuna-like species in Atlantic and adjacent seas fisheries. Although ICCAT has...
In France, the absence of further development of marine fish farming over the last 20 years has been attributed to regulatory constraints, and to the difficult access to new farming sites, due to high competition between different uses in the coastal zone. The Regional schemes for the development of marine...
Based on stochastic frontier analysis, this paper estimates the technical efficiency of aquaculture in 29 provinces and cities in China from 2007 to 2015. Based on this, the output elasticity of each input factor and the influencing factors of technical efficiency are analyzed. The results show that the whole of...
Lake Chapala’s fisheries have been the support of an important economic activity for hundreds of years. At the end of the XIX century, in addition to the fishers, the processing industry employed hundreds of families in the drying and salting of fish. The later introduction of carpe and tilapia forced...
Birds, mammals, and fish eat Atlantic Herring. For the first time, fisheries managers in New England are explicitly considering these, and other, predators when setting harvest control rules for the Atlantic Herring fishery. Based on single-species biological reference points, the herring stock is currently well above MSY levels. However, management...
The large lakes (Victoria, Albert, Kyoga, George, and Edward), covering 75% of Uganda’s surface area under contribute up to 90% of the capture based fisheries production. Until the late 2000s, the commercial fisheries in these lakes was largely based on species that grow to large sizes (> 20 cm) including;...
Stated choice random utility frameworks are a valuable tool for eliciting the preferences of fishermen. In typical applications, choice outcomes are known prior to choice selection, which may confound results when outcomes are uncertain. To evaluate the importance of uncertainty in decision making, we applied a contingent sequential stated choice...
The welfare gains from incorporating ecosystem considerations into fisheries management are unclear and can vary widely between systems. Additionally, welfare gains depend on how ecosystem considerations are adopted. This paper uses an empirically parameterized bioeconomic model to explore the welfare implications of two definitions of ecosystem-based fisheries management (EBFM). We...
The assessment of data-limited fish stocks is crucial for the sustainable management of marine living resources. Dependent on the scope and type of available data, a range of assessment methods are available, such as catch-only, length-based, or catch and survey-based methods. However, these methods suffer from several shortcomings, such as...
South Pacific albacore is a species of primary importance in the longline fishery of a number of Small Island Developing States in the Western and Central Pacific Ocean. Despite the fact that the stock is assessed as not being subject to overfishing, nor overfished, economic returns have declined significantly over...
Scarcity of wild-caught seafood has incentivized innovation and growth in aquaculture, especially for species that compete directly with wild alternatives. In the global tuna industry, the most pronounced scarcity is associated with bluefin tuna species (Atlantic, Pacific, and Southern, which serve similar markets). Supply-side factors including overfishing and governance challenges...
This work is part of the SUCCESS project (Work Package 4: Competitiveness and sustainability of European fisheries and Aquaculture sectors) funded by the EC (H2020, GA 635188). The dynamics of the value chain in eight different species at the Spanish market has been studied using price integration methodologies. Cases of...
Safety outcomes are one measure of the performance of a commercial fishery. Catch share management, which allocates fishing quota to individual vessels or entities, may reduce economic incentives to engage in risky behavior in the “race to fish”. The Multispecies Fishery in the Northeast region of U.S. is considered the...
Complex social–ecological systems such as small-scale fisheries require the inclusion of human dimensions in fisheries management and planning for simultaneously preserving human health and habitat health. However, linkages between ecological, social, political and economic subsystems have been largely ignored in conventional fisheries management, in Nigeria in particular. Hence, the weak...
