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).

The different types of fishing operations may vary significantly in their ability to meet policy goals and hence, in order to plan for optimal resource use, knowledge of the overall performance of the different segments in a fishing fleet is essential. This study compares small and large-scale fishing operations in the Azores Archipelago, an outermost region of Portugal consisting of 9 islands situated in the NE Atlantic. The fishing sector, although traditionally characterised by a fleet composed of low capacity and unsophisticated small boats and vessels operating in near-shore waters, underwent a rapid development in the mid-eighties and now offers more sophisticated, offshore fishing vessels. Many fisheries, however, continue to be essentially artisanal, playing a significant role in the regional economy by providing an important source of employment, income and trading opportunities. This study attempts to quantify some of the differences between the small and large-scale fishing sectors in the Azores and examines how the two compare in a number of policy-relevant variables, including employment, total landings, number of individual fishing units, fuel consumption and the amount of catch used for direct human consumption. The analysis is based on socioeconomic surveys of the fishing communities in the Region, as well as, several databases on landings and fleet characteristics. The fishing fleet was divided into small and large-scale according to a set of criteria based on vessel size, gear type, target species and catch value.

Since that time, EU data collection regulation has undergone 2 revisions in response to evolving policy needs. The European Commission's Joint Research Centre (JRC) is responsible for conducting research and providing advice on fisheries management under the CFP, and since 2005 has worked closely with the Scientific, Technical and Economic Committee for Fisheries (STECF). JRC and STECF have an open data policy, and aggregated data submitted by EU member states in response to data calls issued under the provisions of the data collection regulation are published via the website of the STECF. This paper provides an overview of the fisheries data activities carried out by the JRC in support of and in collaboration with the STECF and discusses some of the benefits and drawbacks of such activities.

In 2022, the EU fishing sector paid on average about EUR 0.93 per liter of fuel; at the peak of the crisis in June, it paid EUR 1.2 per liter, around three times the normal average price. High fuel prices jeopardize the viability of the fishing sector, which is largely fuel-intensive and particularly vulnerable to fuel price increases. The European Commission responded with emergency measures, adopting a Temporary Framework for State aid rules and activating the crisis mechanism foreseen under the European Maritime, Fisheries and Aquaculture Fund (EMFAF). This communication aims to examine the economic impact of the high fuel prices and the financial support available to the EU fishing sector to assess the short-term and long-term sustainability of the EU fishing sector.

This paper provides an analysis of the COVID-19 impacts on the profitability of the EU fishing fleets. Nowcasting techniques were used to estimate the impact of the COVID-19 pandemic on the economic performance for the EU fishing fleet in 2020 and 2021. Our results show that the economic impact of COVID-19 on this sector was smaller than initially expected and overall profits remained positive. This was in part due to low fuel prices that reduced operating costs of fishing, and the early response from governments to support the sector. The results vary by fishing fleet, revealing that small-scale fleets and the fleets in the Mediterranean and Black seas have been more impacted than large-scale fleets and the fleets in the Northeast Atlantic.

Based on data submitted by Member States under the EU MAP, there were 65 567 active vessels in 2017. Direct employment generated by the fleet amounted to 151 981 fishers, corresponding to 107 807 FTEs; on average earning EUR 28 362 in wages annually. The EU fleet* spent 4.8 million days-at-sea and consumed 2.2 billion litres of fuel to land 5.3 million tonnes of seafood with a reported value of EUR 7.6 billion. Revenue (income from landings plus other income), as reported amounted to EUR 7.7 billion while costs incurred by the fleet amounted to EUR 6.4 billion (excludes fishing rights), 11% of which consisted of capital costs and 89% of operating costs. The latter mainly consisted of labour and fuel costs (39% and 16% of costs, respectively). The Gross Value Added (GVA) and gross profit (all excl. subsidies and fishing rights) was estimated at EUR 4.5 billion and almost EUR 2.0 billion, respectively. GVA as a proportion of revenue was estimated at 58% and gross profit margin at 26%. With a total net profit of EUR 1.3 billion in 2017, 17% of the revenue was retained as profit. This publication includes: 1) An structural and economic overview of the EU fishing fleet in 2017, with nowcasts for 2018-2019, and trend analyses for the years 2008-2017/18; 2) A regional analysis of the EU fishing fleet by major sea basin: North Sea & Eastern Arctic, Baltic Sea, North Western Waters, South Western Waters, Mediterranean Sea, Black Sea, as well as, fleets operating in Other Fishing Regions, covering the EU Outermost Regions and fishing areas outside EU waters and in Areas Beyond National Jurisdiction, covered by Regional Fisheries Bodies (e.g. NAFO and ICCAT); 3) A detailed structural and economic overview of each EU Member State fishing fleet, including qualitative economic performance assessments for 2017 and nowcasts for 2018 and 2019.JRC.D.2-Water and Marine Resource

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 obligatio...

The current study lists verified records of non-indigenous species (NIS) in European marine waters until 2020, with the purpose of establishing a baseline, assessing trends, and discussing appropriate threshold values for good environmental status (GES) according to the relevant European legislation. All NIS records were verified by national experts and trends are presented in six-year assessment periods from 1970 to 2020 according to the European Union Marine Strategy Framework Directive. Altogether, 874 NIS have been introduced to European marine waters until 2020 with the Mediterranean Sea and North-East Atlantic Ocean hosting most of the introductions. Overall, the number of new introductions has steadily increased since 2000. The annual rate of new introductions reached 21 new NIS in European seas within the last six-year assessment period (2012–2017). This increase is likely due to increased human acti...
