Fisheries development projects are undertaken ever year in recognition of the important role fisheries play in many coastal communities. The objectives vary, but typically go beyond a limited focus on fisheries management and the ecosystem. This makes it difficult to evaluate the contribution of a project, particularly in data poor...
We present the results of integrating the fisheries sector into an existing computable partial-equilibrium global model of agriculture, livestock, bioenergy, forestry, and land use. The model is constructed by reconciling publicly available global datasets from the FAO as well as the literature. The model of the fish sector represents capture...
While buybacks don’t have the cache of rights-based programs they are often pre-cursors to longer-term management solutions. The authors assess a proposed buyback program in Eastern Pacific (EPO) purse seine fishery that has the potential to increase post-buyback profitability, and which could also provide the means to alleviate long-standing internecine...
As fisheries management is increasingly required to consider the full impacts of their operations, this work seeks to define the relationship between fishing effort and interactions with listed endangered species. The study employs logbook data containing over 64,000 sets, matched with observer data from 2008 to 2015 in an undisclosed...
In 2015, baseline expenditure and trip behavior information about angler activity across a 14-county region of California’s Central Valley was collected. The motivation for this study was twofold: to learn about existing recreational fishing levels in the Sacramento River system, and to understand how these levels might change if fishing...
Poaching is a major problem under the Chilean system of territorial use rights in fisheries (TURFs). Organizations of artisanal fishers that are granted spatial property rights through TURFs combat poaching by establishing their own enforcement. Although an organization must protect its benthic resources against poachers from both within the organization...
A growing practice in fisheries management is the allocation access rights to marine fisheries through individual transferable quota (ITQs) – limits on the amount of fish allocated to individual licences as transferable permits. By establishing an ownership claim over the right to fish and a market for exchange, ITQs are...
Climate projections indicate that ocean temperatures will continue increasing, potentially shifting the distribution of marine fish species and affecting the economics of the fishing industry and fishing communities. In this study, an integrated ecological-economic framework is used to evaluate the economic impacts of climate-driven species changes and assesses the value...
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...
In the European Union (EU), marine resource management policies and legislation include not only environmental objectives but also a broad range of explicitly stated economic, social and institutional (ESI) goals, objectives and priorities. Although the environmental objectives often guide scientific assessments, the ESI objectives are often the primary drivers of...
This paper discusses the importance of the fishing industry – fishing fleet and processing industry – for the development of coastal communities. Statistical analysis is performed to analyze the importance of development in the fisheries sector (catch, landings, employment et.c) and how and to what degree this explains the growth...
The focus of this study is the development of the Icelandic trawler fleet and the drivers behind the changes. The first stern trawlers began operation in 1970, five years later there were 58 fishing in the EEZ and in 1982 their number reached above 100. Excess capacity and overcapitalization characterized...
The Florida reef ecosystem is a highly valuable resource managed by multiple federal and state agencies with many stakeholders. Over half of the $75 million annual dockside value of finfish landings in Florida is comprised of snappers and groupers, but this resource is threatened by overfishing. Current management strategies include...
In Norway, structuring of the fishing fleet has been an ongoing process since the start of the 1960'ies. Since then, both the number of vessels in Norwegian fisheries and fishers have been reduced by roughly 85 %. For decades, the fisheries industry has been considered a mean to employment and...
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,...
The feed conversion ratio (FCR) or its reciprocal, the feed efficiency ratio (FER) is currently used to estimate the feed requirements in aquaculture. This has a serious disadvantage. The FCR is a function of feeding rate, initial and final mass at fattening, temperature and quality of feed. Therefore the FCR...
How well at fishery management regime perform is closely related both to vessel performance (i.e. return on investments) and if the species at stake are harvested in sustainable manner. However, ROI do not capture important dimensions of vessel performance. In addition, sustainability also includes social, economic and institutional dimensions. In...
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...
A primary objective of fishery management is profit maximization, accomplished by managing externalities associated with catching fish, while acknowledging that some margins of fishing fall beyond regulatory bounds. Regulation often does not address the larger economy of which the fishery is a part, focusing instead on the cost--benefit structure of...
Fisheries economics has recently earned a seat at the global fisheries governance table, with everything from subsidies, to high seas fisheries, to Indigenous rights, food security, and human rights now being open for global assessment. The papers in which these studies are housed are in high impact journals, are highly...
This paper examines the regulatory decision problem facing fishery managers tasked with balancing desirable fish catch with undesirable bycatch. I approach the problem using Bayesian decision analysis. I first estimate a model of production, accounting for the fishery’s joint production of desirable and undesirable outputs. I then use the estimated...
Iceland had several disputes with its neighboring countries during the fifties, sixties and seventies over expansions of sovereign waters and control of fishing rights, known as the cod wars. Iceland was successful in securing exclusive fishing rights for its people. However, the problem of overexploitation, which lay at the heart...
Socio-economic analysis of seafood production is important for the conservation of aquatic ecosystems and the management of fisheries and aquaculture activities. Understanding how the livelihoods of people, dependent on the exploitation of aquatic resources, are affected by various changes is essential for decision making. The two main seafood production sectors,...
Based on a simple model of firm profit maximisation in a multispecies ITQ fishery, market clearing quota lease prices are modelled as a system of linear equations with dimensions dependent upon the number of quota species in the fishery and the number of different harvesting technologies.
