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...
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...
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...
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...

The Abalone Fishery is one of Victoria's most valuable commercial fisheries and almost all of the catch is exported to international markets, predominately in Asia. An outbreak of a virus called the Abalone Viral Ganglioneuritis (AVG) decimated one third of Australia’s abalone, starting in 2005. However, there has been little...
The Abalone Fishery in one of Victoria’s most valuable commercial fisheries and most of the catch is exported to international markets in Asia (Japan, Hong Kong, Singapore, China). Target species consist of blacklip abalone and greenly abalone (<1% of total catch). The fishery is quota managed, and the total allowable...
Research on small-scale fisheries has largely focused on men’s fishing practices and perceptions and considerably discounted the important contributions by women to household food security and economies (Harper et al. 2013). Studies in most West African countries confirm that post- harvest activities is gendered in nature and revolves around traditional...
While there has been a global proliferation of marine certification schemes aiming to incentivize sustainable fishing in the last decade, the uptake has been comparatively slow in Japan. Suggested reasons include difficulties assessing Japanese fisheries co-management institutions, and reduced profitability from complex seafood distribution networks and mismatched consumer preferences. However,...

Decision-making in aquaculture is becoming increasingly complex due to the need of taking into account large volumes of data, and to consider other aspects besides the economic ones, such as product quality or the environmental sustainability, which are sometimes opposing and difficult to integrate. However, the development of simulation and...
Although aquaculture is the food-production industry that has grown the most in recent years, its companies inherently face more variability in their results than companies from other industries This can be explained by the increasing complexity in their decision-making processes, due to the large number of, external and internal, influencing...
Fishing systems provide employment, income generation, poverty alleviation, and food security. The coexistence of small-scale fisheries (SSFs) and large-scale fisheries (LSFs) increases management complexity. Management actions have ecological and social implications that must be addressed carefully. We applied a bioeconomic game-theoretical model to the four-gear mullet fishery in southern Brazil—one...
Fishing systems provide employment, income generation, poverty alleviation, and food security. Management actions have ecological, economic and social implications that must be addressed carefully. The coexistence of small-scale fisheries (SSFs) and large-scale fisheries (LSFs) increases management complexity. Game-theoretical bioeconomic models empower management decisions in such complex systems.

Introduction: The issue of the economic relations between major fishing countries (EU and Asian countries) if of major concern: Overt and tacit vessel subsidies, the asymmetry in the benefits for lower income and higher income countries from fishing and fish processing, LDC EEZs account for around 11 per cent of...
The valuation marine ecosystem services have been receiving increasing attention in scientific literature, however most of the research is focused in marketed services and does not consider the part of the total economic value. Some services like cultural services that are not direct (touristically) or indirectly marketed as part of...
One pressing economic, societal and environmental issue affecting commercial fisheries is the production of undesirable outputs. In fisheries, undesirable outputs often arise because of economic or regulatory discarding of commercial species and/or the incidentally caught or ‘take’ of protected species, such as sea turtles and marine mammals. In fisheries, undesirable...
The EU framework for the collection and management of fisheries data (EU Reg. 1004/2017) requires estimates of four variables related to capital value and capital cost of fishing fleets, i.e. Consumption of fixed capital, Value of physical capital, Value of quota and other fishing rights, Investments in tangible assets. The...
Marine recreational fishing (MRF) is a leisure activity and a cultural ecosystem service that, beyond the welfare obtained by its practitioners, has an interesting potential to boost maritime economies. However, it does not represent a formal sector on the national accounts and, in Europe, it lacks a systematic and common...
First-sale prices of fish respond to both local and global drivers, and artisanal fishermen are often considered as price-acceptors due to their limited capacity to influence them, a key issue for their survival and value added creation. However, in artisanal fisheries, the frequent lack of data hinders us from understanding...
Introduction:
SSFs → Own characteristics that often affect prices. First‐sale prices are key for the sustainability of SSF,often price‐acceptors → influence of supra‐local factors (exports, imports, value‐chain forces) and industrial fisheries. Certain local/regional SSF management measures also aim to have effects on this price: fisheries regulation, commercial strategies, labelling, etc....
Context and objective: Beyond leisure and food (sea ES) → MRF boosts maritime economies, but not a formal industry in our economic accounts. EU DCF → increasing focus on MRF, to be considered in commercial fisheries management decisions (CFP). Limitations of traditional approaches (aggregated expenditures,non‐market microeconomics) to assess MRF economic...
The Cíes Islands show an extremely rich biodiversity, making them the core element of Galicia’s Atlantic Islands, and are an extremely attractive area for the development of small-scale fishing, as well as for tourism and recreational activities, which could constitute a priori a potential risk insofar as maintaining the natural...
Diversification of fishery revenue can reduce interannual variation in revenue and thereby lower financial risk (e.g., Kasperski and Holland, 2013; Cline, Schindler, and Hilborn, 2017; Sethi, Reimer and Knapp 2014; Anderson, Ward and Shelton 2017), Average fishery diversification levels on the US West Coast have been declining over time –...
