This report assesses how current management actions are adhering to the original mandate set by the Wilderness Act of 1964 by monitoring the five qualities of Wilderness character (untrammeled, natural, undeveloped, opportunities for solitude/unconfined recreation, and other features of value) as they pertain to this specific Wilderness area.
This collection houses the proceedings of the 20th biennial conference of the International Institute of Fisheries Economics & Trade (IIFET), entitled Managing a Changing Environment. The conference took place at Auditorio Mar de Vigo in Vigo, Galicia, Spain, from 18-22 July 2022. Conference organizers were M. Dolores Garza-Gil (University of...
Policy makers must ensure that regulatory frameworks contribute to the maintenance of resilient marine ecosystems. Recreational fishers add additional pressure on worldwide fish stocks to that exerted by commercial fishing, especially in coastal areas. Fishing tourism have an increasingly stronger presence in areas with growing numbers of permanent residents. Marine...
Iceland adopted an ITQ system for all of its fisheries more than three decades ago. The system has worked well in increasing the economic performance of the fisheries and, at least seemingly, the enforcement of the TACs. The Fisheries Directorate (FD) is aware of the potential problem of discards and...
In this paper, we analyze how public monitoring and enforcement (M\&E) efforts affect the success of a collective property right. We develop a bioeconomic model to generate several theoretical predictions, which we test empirically by assembling and analyzing novel data on public patrolling and fishing activity in the Chilean abalone...
Artificial reefs (AR) were created not only to enhance biodiversity (namely by stimulating the increase of fish stocks), but also to attract diving tourism or sport fishing enthusiasts. Industry 4.0 tools – e.g., mobile technologies and cloud computing – can be used for AR monitoring purposes and can serve as...
Artificial reefs (AR) were created not only to protect sea bottoms (Lee et al., 2018) and enhance biodiversity namely by stimulating the enhancement of fish stocks (Pioch et al., 2020), but also to attract diving tourism (Shani et al., 2012) or sport fishing enthusiasts (Radonski et al., 2018). In order...
Global Trends: Foreign and transnational ownership (& ownership interests), Complex structures: vertical integration, flags of convenience, joint ventures, etc., Concentration: a handful of corporations controlling global fisheries (Österblom et al. 2015,Carmine et al. 2020). Why Regulate?: Risk of monopolies and market failure, Governance of corporations (i.e., compliance, enforcement), Who captures...
Over recent decades, the EU aquaculture sector has been implementing actions towards the minimization of waste as a strategy for increasing the circular attributes of the management system. In this context, it is relevant to develop methodologies to quantify and assess the circularity that will ultimately be achieved by new...

There is no doubt that policy makers must ensure that the different regulation frameworks contribute to the maintenance of resilient ecosystems that sustain healthy resources for commercial fishers, contributing to the economies that depend on their activity and supply markets with healthy products. However, marine recreational fishing also contributes significantly...
The European Union, under the European Maritime and Fisheries Fund, implement the Community-Led Local Development (CLLD). This programme is designed to address the main challenges faced in the fisheries areas by proposing and testing new solutions by the coastal population. In this sense, Spain plays a key role due to...
This is an empirical analysis of the Malindi Ungwana Bay prawn fishery in the coast of Kenya. A resource allocation problem is at the heart of the conflict between artisanal fishers and commercial trawlers exploiting the prawn fishery in the bay. The Prawn Fishery Management plan by the government has...
Bermeo is a small town in the north of the Iberian Peninsula, cradle of a purse seiner of undisputed global relevance. Since the time of the Romans, it was recognized for its port, which led it to be one of the first three villages that were founded in the former...
Region policy instruments that transfer funds between jurisdictions are popular tools for mitigating spatial economic disparities. Given the regional aspect of fishing activity, these policy tools often benefit fisheries firms. In this paper, I study the effect of the regional policy area in Norway- a geographical area that is, among...
The small-scale coastal fisheries of Virginia account for a significant portion of the state’s total annual landings and employ thousands of individuals. Despite the value of these fisheries, the number of commercial licenses sold has declined more than 15% since 1994. Declines are attributed to various factors, but indicate potential...
This paper identifies the effect of Mauritian regulation changes on EU industrial vessels’ fishing activities and their implications for food security. The rich resources of Mauritanian waters have historically been utilized by large foreign trawlers, creating small ripple effects and jobs in Mauritania. However, in 2012, Mauritanian authorities introduced new...

Low-value fish/ fishery by-products are potential economic resources for developing animal feeds. Accordingly, fish protein hydrolyzed technology is an excellent way to provide protein sources for animal nutrition. However, the nutritional quality and applying this new feed supplement are severely related to the production stages and next characteristics of agricultural...
Myctophid/lanternfish is one of the major fish stocks in the Oman Sea. The commercial utilization of lanternfish in the Persian side of the Oman Sea began in 2007. The vessels catching the lanternfish have not been specifically designed and equipped for this fishing operation. In addition, the lack of purposeful...
Why did I write a novel? Fisheries operate in complex adaptive systems. A novel can better illustrate the dominant role of system complexity in sector governance. A book may last longer than a paper. I like writing a story, even if it is an illusion within reality.
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...
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...
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...
Nigeria with an annual potential of 2.5 million tonnes of fish from aquaculture produced only 316,727 tonnes in 2015 out of the domestic production of 1.027 million tonnes and total fish demand of 3.25 million tonnes. The government has put in place a lot of initiatives to increase aquaculture production...
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.
The estimation of production frontiers using revenue as the dependent variable is very common in fisheries research since in multi-species fisheries boats catch several species and their output must be aggregated somehow. The objective of this paper is to decompose revenue efficiency into two components, one due to quantities and...
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...
Iran is among the pioneers in the farming of rainbow trout that is mostly up to 1 kg with a production of 173,000 tonnes in 2018, principally used for domestic consumption. Farmers use labour-intensive hand feeding and counting eggs by hand. Imported trout eggs are preferred to domestic eggs as...
This contribution aims to provide an economic assessment of the seabream and seabass industry in the Mediterranean, in order to describe the recent development and current situation of the economy and markets of this industry. It focuses on analyzing the economic and financial structure at different levels of aggregation (industry,...
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 main objective of this study is to assess seafood marketing and pathway in Nigerian coastline (the case of Lagos and Ondo States in the South West, Nigeria).
The specific objectives were to determine the: demographic characteristics of seafood marketers in the study area; gender pathway involved in seafood marketing...
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 –...
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...
Southwest Atlantic (SWA), corresponding to FAO Area 41, covers a total surface area of 17.65 million square kilometres. It spans from 5°N latitude off the coast of Brazil, to 60°S latitude off the coast of Argentina. Most of the area is classified as High-Seas, defined by the Convention of the...
We apply the Fishery Performance Indicators (FPIs) methodology to the Southeast Pacific Anchoveta Fishery off southern Peru and northern Chile. Our basic model of analysis is a production function framework, where the performance outcomes are a result of the available inputs. We measured all FPI categories (outcomes and input metrics)...
This paper studies the price volatility transmission between the different markets along the value chain of fresh anchovy (Engraulis encrasicolus) in Spain. For this purpose, the prices at the ex-vessel market, the wholesale market and the retail market are considered. As a methodology, a Vector Autoregressive Model (VAR) and an...
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...
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,...
