The EU-27 fishing fleet consumed 2.02 billion liters of fuel to catch 4.48 million tons of fish, valued at €6.7 billion in 2018. The profitability of the EU fishing fleet shows an increasing trend, partly due to the improvements in the energy efficiency and recovery of fish stocks in the North-east Atlantic. Fuel is one of the main expenses fishing fleets have, and therefore, their economic performance remains highly dependent on the fuel price, even if they benefit from a fuel tax exemption. The adoption of the European Green Deal, the revision of the Energy Taxation Directive (ETD), the ongoing World Trade Organization (WTO) negotiation to prohibit harmful fisheries subsidies, and general public opinion are putting pressure to eliminate this tax exemption. This analysis investigates the impacts of the potential elimination of the fuel tax exemption across the different EU fishing fleets and it is discussed to what extent the small-scale, large-scale and distant-water fleets could be affected. This analysis is useful to inform policy-makers and stakeholders on the consequences of the potential elimination of the fuel tax exemption, as well as to discuss potential measures to mitigate the socioeconomic impacts arising from this eventual change in the current regulatory framework.

Fisheries management is about the steering and supervision of the exploitation of a common-property natural renewable resource. Costs inherent to fisheries management have been too often ignored, even if management expenditure represents a significant share of the landings value. This omission occurs in part because often taxpayers are the ones who bear the costs while the benefits of fisheries management are mostly reaped by the fishing industry. This has crucial implications when estimating the net economic benefits for the society, which differ from the private profits of the sector. In this study, we estimate the economic performance of the EU fishing fleet in the Northeast Atlantic in relation to management objectives and taking into account the cost of management. Results not only highlight the importance to account for management costs in order to differentiate between private profits and benefits for the society but also raise awareness on the management expenditure and who pays for it.

In contrast to the increasing aquaculture production of mussels worldwide, production in the European Union (EU) has shown a decreasing trend over the last two decades. Aquaculture production of mussels in the EU peaked in the late 1990s at more than 600 000 tonnes; by 2016, production volume had dropped by 20% to 480 000 tonnes. As mussel production represents more than ⅓ of EU aquaculture production, this decrease is an important contributor to the stagnation of EU aquaculture. Previous studies have suggested diseases, lack of mussel seed (spat), and low profitability as the main causes of the EU mussel production decrease. In this study, we investigate how economic and environmental factors have contributed. Moreover, we examine if the different mussel production techniques (raft, longline, on‐bottom, and ‘bouchot’) have been differently affected, by analysing the economic performance and cost structure evolution for the period 2010–2016. We complement these results with a SWOT (strengths, weaknesses, opportunities, and threats) analysis of the EU mussel sector based on expert knowledge.

In most economic sectors, increases in capital (i.e., investments) are often considered virtuous, indicating confidence in the future and expected growth. In fisheries, however, investments are often harmful, as they may lead to increases in fleet capacity, which is not desirable considering the fully exploited or overexploited status of most fish stocks (natural capital), and the dissipation of the resource rent (overcapitalisation). In the EU, the number of fishing vessels have been decreasing for many years, but the fishing capacity is often claimed to have increased. In other words, there are less vessels, but the remaining ones have a higher fishing capacity. In this study, we analyse the evolution of the EU fishing industry’s investments for the period 2008–2016, and whether these investments have been beneficial. Results show that despite the overall decrease in the number of vessels and their average value, investments in some fleets have increased. Moreover, investment decisions (i.e., whether to invest or disinvest) have been more accurate in recent years, leading to a better economic performance. However, results vary by the scale of the fishing activity (small-scale and large scale fleets) and sea basin (Northeast Atlantic Ocean and Mediterranean Sea).

Through its structural funds the European Union (EU) has invested €1.17 billion in the aquaculture sector over the period 2000–2014. In addition, the EU plans to spend a further €1.72 billion on the sector over the period 2014–2020 through the European Maritime and Fisheries Fund (EMFF). Despite this support, EU aquaculture production has not taken off. Indeed, EU production volume in 2016 was 8% less than in 2000, while global production increased by more than 150%. These investments aim to make the EU aquaculture sector more successful and competitive by focusing on quality, health and safety, as well as, eco-friendly production to provide consumers with high-quality, highly nutritional and trustworthy products. This study provides the first comprehensive overview on the allocation of the different structural funds in the aquaculture sector and across EU Member States from the year 2000–2020. The importance of these subsidies is put into perspective by comparing their evolution within and across the development of the different EU countries’ aquaculture sectors.

Evidence from DNA‐analysis is commonplace in human criminal investigations, and while it is increasingly being used in wildlife crime, to date, its application to control and enforcement activities in fisheries and aquaculture has only been sporadic. Contemporary DNA‐analysis tools are capable of addressing a broad range of compliance issues, species identification, mislabelling of fish products, determining the origin of catches and the farm of origin of aquaculture escapees. Such applications have the potential to ensure traceability along the fish product supply chain and to combat consumer fraud and Illegal, Unreported and Unregulated fishing. Nevertheless, DNA‐analysis is not yet used routinely in investigations into compliance with fisheries and aquaculture legislation. One potential reason for this is that DNA‐analysis techniques may have been regarded as too expensive. However, costs have plummeted over the past decade prompting us to objectively assess whether the costs associated with routine use of DNA‐analysis techniques for fisheries and aquaculture control and enforcement activities do constitute an impediment. Based on a number of recent fisheries and aquaculture compliance investigations that incorporated DNA‐analysis, our results indicate that the use of genetic analysis was justified and worthwhile in all cases examined. We therefore conclude that the costs associated with DNA‐analysis do not represent a barrier to the routine adoption of DNA‐analysis techniques in fisheries and aquaculture compliance investigations. Thus, control and enforcement agencies should be encouraged to use such techniques routinely.

To ensure food security and nutritional quality for a growing world population in the face of climate change, stagnant capture fisheries production, increasing aquaculture production and competition for natural resources, countries must be accountable for what they consume rather than what they produce. To investigate the sustainability of seafood consumption, we propose a methodology to examine the impact of seafood supply chains across national boundaries: the seafood consumption footprint. The seafood consumption footprint is expressed as the biomass of domestic and imported seafood production required to satisfy national seafood consumption, and is estimated using a multi-regional input output model. Thus, we reconstruct for the first time the global fish biomass flows in national supply chains to estimate consumption footprints at the global, country and sector levels (capture fisheries, aquaculture, distribution and processing, and reduction into fishmeal and fish oil) taking into account the biomass supply from beyond national borders.

Discarding is a common practice in fisheries. Total discards are estimated to be about 30 million tons, representing around 23% of worldwide catches. Discarding is an undesirable practice, not only because of the waste of resources, but also because of its contribution to the overexploitation of fish stocks. Several countries have already established discard bans, to different extents (e.g., Norway, Iceland, Chile, New Zealand). The EU’s landing obligation (discard ban) is a major measure of the latest reform of the Common Fisheries Policy for EU fisheries. It aims to reduce unwanted catches in EU fisheries, by incentivizing improved selectivity and restoring fish stocks to levels that can sustain the maximum production over time without harming the biodiversity and the capacity of future generations to obtain fish. However, banning discards will inevitably induce diverse short- and long-term ecological, economic, and social impacts, which may determine whether the landing obligation’s objectives will be achieved.

Marine ecosystems evolve under many interconnected and area‐specific pressures. To fulfil society's intensifying and diversifying needs while ensuring ecologically sustainable development, more effective marine spatial planning and broader‐scope management of marine resources is necessary. Integrated ecological–economic fisheries models (IEEFMs) of marine systems are needed to evaluate impacts and sustainability of potential management actions and understand, and anticipate ecological, economic and social dynamics at a range of scales from local to national and regional. To make these models most effective, it is important to determine how model characteristics and methods of communicating results influence the model implementation, the nature of the advice that can be provided and the impact on decisions taken by managers. This article presents a global review and comparative evaluation of 35 IEEFMs applied to marine fisheries and marine ecosystem resources to identify the characteristics that determine their usefulness, effectiveness and implementation. The focus is on fully integrated models that allow for feedbacks between ecological and human processes although not all the models reviewed achieve that. Modellers must invest more time to make models user friendly and to participate in management fora where models and model results can be explained and discussed. Such involvement is beneficial to all parties, leading to improvement of mo‐dels and more effective implementation of advice, but demands substantial resources which must be built into the governance process. It takes time to develop effective processes for using IEEFMs requiring a long‐term commitment to integrating multidisciplinary modelling advice into management decision‐making.

The main objective of this paper is to investigate the existence of an economic crisis-induced demand shift in the Spanish fish market. This is performed by endogenously examining whether the existence of a structural break in fish price trends around 2008, corresponding to the collapse of the Spanish economy, together with an asymmetric and specific price behavior regarding the sign and magnitude of the expected income elasticities of three staple fish species (i.e., sardine, anchovy and hake). Our data corroborate not only the structural break hypothesis for rooted luxury and inferior fish species in the Spanish market but also an opposite price response after the break, which explains the increasing pressure on cheap fish demand and conversely the lower demand for expensive fish products. Results show consistency for all market levels analyzed (i.e., origin, wholesale and retail). [EconLit citations: C22, Q31].

Gilthead seabream (Sparus aurata) and European seabass (Dicentrarchus labrax) production from aquaculture has been increasing since the 1990s. Nowadays, about 95% of their production comes from aquaculture. In this study, we analyse if the rapid growth in the aquaculture production of both species has affected the capture fisheries prices of both species. In other words, we investigate if there is market integration between wild and farmed gilthead seabream and European seabass. In order to do this analysis, we use data from the main gilthead seabream and European seabass markets in Spain. The results show that there is no market integration between wild and farmed gilthead seabream and European seabass. This implies that capture fisheries are not affected by increases in the aquaculture production of both species. But gilthead seabream and European seabass aquaculture producers face a smaller demand that explains the difficulties this aquaculture segment is facing.

Despite the growing importance and high priority assigned by the EU policy makers to the development of aquaculture, little attention has been given to analyze the economic performance of the sector at EU level. Recently, the profitability of the EU aquaculture sector has been estimated by the European Commission’s Scientific, Technical and Economic Committee for Fisheries (STECF). However, the few studies that have estimated the profitability of the EU aquaculture sector show sometimes divergent results. In this paper, the economic performance of the EU aquaculture sector is analyzed by country, segment and main species for the years 2006, 2009 and 2010 using financial and accounting data extracted from the Amadeus database and results are compared to other studies. This analysis helps to understand the methodological differences between the diverse sources. Moreover, this alternative methodology offers a simpler and faster alternative to the STECF’s profitability estimates of the aquaculture sector. The analysis indicates that after the economic downturn, companies started to recover profits in 2010 in almost all segments and countries, and that the highest profitability is recorded by companies in the marine segment as compared to freshwater and shellfish.

MSY objectives are being adopted as major fisheries management targets worldwide. However, in fisheries where discards account for an important share of the catches, the yield, effort, and biomass at MSY can be significantly different when accounting or not for discards and thus when, basing the yield estimations on landings or catches. Also whether accounting for a certain survival rate, of discards can lead to different MSY targets estimates. Hence, both decisions have important, implications on catch and effort reduction recommendations, and consequently on the quota, calculations for fisheries managed by quotas. Results from the Bay of Biscay nephrops fishery confirm, that the optimal exploitation level can vary significantly when optimising for catches or landings, and, by assuming a certain survival rate of the discards. By doing this, the present study also allows to, explore the basis to clarify the definition of MSY in fisheries where discarding takes place.

5 pages, 3 figures, 2 tablesThe importance of temporal (such as the day of the week, month and year) and spatial (port of origin, distance to main market) factors are measured in the price determination of a luxury seafood item, the red shrimp (Aristeus antennatus), using a hedonic price function. In hedonic analysis the price of a product is specified as a function of the attributes and factors that characterize the product, such as quality or origin. In this analysis there are used the daily ex-vessel data of red shrimp caught by the deep-water trawl fishery for the main fishing ports in Catalonia (North-West Mediterranean) for the period 2000-2012. Results show the importance of port of origin, seasonality, volume of landings and a decrease in price since 2008 due probably to the current world financial crisis. The day of the week, although of relatively lower importance in the models, shows that red shrimp prices are lower in Tuesdays and Wednesdays (14% lower than on Fridays). Management measures based on effort reduction in this input-controlled fishery could target these days when red shrimp price is lower in order to minimize the short-term adverse economic effect of effort reduction on the trawl fleet. © 2014 Elsevier Ltd.Peer Reviewe

This paper analyzes the impact of applying vessel detection technology using satellite images (vessel detection system, VDS) to complement air patrols for fisheries enforcement and control. Due to limited fisheries enforcement budgets there is the need to allocate costs efficiently among competing control tools. This paper focuses on assessing the benefits of using VDS jointly with VMS (vessel monitoring system) and air patrol surveillance to improve effectiveness of controls. A statistical model to estimate the number of inspections was developed and was used with enforcement costs data as reported by a number of EU countries. The result of applying VDS in fisheries enforcement is presented in one of the most demanding fisheries enforcement contexts: the Mediterranean bluefin tuna (BFT) fishery.
