Inter-species quota flexibility (IQF) is a new management tool made available to fishery managers in the reformed European Common Fisheries Policy (CFP) launched in 2013. IQF regulates a limited transfer between stockspecific total allowable catches (TAC), the main measure of stock conservation in CFP set in accordance with precautionary or, where possible, analytically estimated levels of maximum sustainable yield (MSY). IQF is intended to mitigate the various potential conflicts in the management of multi-species fisheries resulting from stricter catch limitations, which, in turn, are due to the newly-introduced landing obligation for all catches of TAC-regulated stocks. In this paper, the management implications of inter-species flexibility are evaluated by modelling various scenarios of individual and multiple multi-species fisheries exploiting virtual stocks of different sizes and productivity. The results reveal that IQF is rather ineffectual if sustainable stock-specific management goals are similar in terms of exploitation rate. However, if these goals are modified in response to potential ecological conservation needs or market considerations – which would reflect reality more closely – IQF may offer a frequently applicable and effective tool. Simulations carried out in this study demonstrate that IQF may support the use of quotas by increasing fishing opportunities of by-catch species, which are then subtracted from the target stock allowances. However, multiple and jointly managed multi-species fisheries frequently appear limited due to reduced fishing opportunities of target stocks, which may prevent the progressive application of IQF. As such, IQF is helpful for certain specific fisheries management, rather than as a tool for broader management approaches jointly applied to different fishing strategies. It is concluded that the application of IQF may undermine the politically-agreed and fixed quota-sharing rule among European member states (i.e. the "relative stability") and also lacks a reference to FMSY; i.e., it remains to be clarified whether the application of IQF would result in tolerable levels of short term overfishing of by-catch stocks with regard to MSY.

[EN] Lipid reserves are a particularly important attribute of fishes because they have a large influence on growth, reproduction and survival. This study analyses the lipid content of red mullet (Mullus barbatus) pre-spawners in three different areas of the northwestern Mediterranean in relation to trawling activities and river runoff. The muscle lipid was considered as an indicator of the somatic condition of individuals whilst the gonad lipid was used as a proxy of the energy invested in reproduction. The results show that fish with the highest muscle lipid levels inhabited the area where fishing impact was lowest. Since the abundance and biomass of polychaetes, which represent the main food source for red mullet, were found to be lower in trawled zones than in unfished ones, we suggest that differences in the muscle lipid levels between areas might be attributed to variation in prey abundance in relation to fishing impact. However, no impact of river runoff on lipid reserves of red mullet was observed. The results also show that muscle and gonad lipid reserves are not related to each other during pre-spawning ; [ES] Las reservas lipídicas constituyen un importante atributo de los peces porque juegan un papel destacado en su crecimiento, reproducción y supervivencia. Este estudio analiza las reservas lipídicas del salmonete de fango (Mullus barbatus) durante la prepuesta en tres áreas diferentes del Mediterráneo noroccidental en relación a la actividad pesquera y las descargas fluviales. Se ha considerado el contenido lipídico en el músculo y en la gónada como indicadores de la condición somática y de la energía invertida en la reproducción de los individuos respectivamente. Los resultados muestran cómo los peces con una cantidad mayor de lípidos en el músculo habitan el área donde el impacto pesquero es menor. Puesto que la abundancia y la biomasa de poliquetos, que constituyen la principal fuente de alimento del salmonete de fango, son inferiores en las zonas afectadas por el arrastre que en las zonas donde no se practica este tipo de pesca, se sugiere que las diferencias en la cantidad de lípidos en el músculo entre las distintas áreas podrían atribuirse a las diferencias en la abundancia de presas, lo cual podría guardar relación con la actividad pesquera. Sin embargo, no se observa impacto alguno de las descargas fluviales sobre las reservas de lípidos del salmonete de fango. Los resultados también muestran cómo los contenidos lipídicos en el músculo y en la gónada de los ejemplares no están relacionados entre sí durante la prepuesta de la especie ; This research was funded by a Marie Curie European Reintegration Grant (MERG) of the European Commission and a C-RED Fellowship from the Government of Catalonia (Spain) ; Peer reviewed

Under the 2013 Reform of the European Union's Common Fisheries Policy (CFP), fisheries management aims to ensure that, within a reasonable time frame, the exploitation of marine biological resources restores and maintains populations of harvested stocks above levels that can produce the maximum sustainable yield (MSY). The CFP also calls for the implementation of an ecosystem-based approach to fisheries management (EBFM). In this paper, we present the concept of maximum sustainable dead biomass (MSDB) and its associated management reference points for fishing mortality and spawning-stock biomass as alternatives to those associated with MSY. The concept of MSDB is illustrated by a dynamic pool production model of a virtual fish stock which takes into account variations in natural mortality (M), fishing mortality (F), and exploitation pattern. Our approach implies a compensatory mechanism whereby survivors may benefit from compensatory density dependence and is implemented through progressive substitution ofMwith F for varying rates of total mortality (Z). We demonstrate that the reference points for fishing mortality and spawning-stock biomass associated with MSDB are less sensitive to increasing compensation ofMwith F than those associated with MSY and more sensitive to changes in selection pattern. MSDB-based reference points, which are consistent with maximum stock productivity, are also associated with lower fishing mortality rates and higher stock biomasses than their MSY-based counterparts. Given that selection pattern can be influenced through fishery input measures (e.g. technical gear measures, decisions on areas, and/or times of fishing), whereas variations of Min response to F are not controllable (indeed poorly understood), that the results of many fish stock assessments are imprecise, that maximum stock productivity corresponds to MSDB and that MSY-based reference points may best be considered as limits, we propose that MSDB-based reference points provide a more appropriate basis for management under an EBFM.

This manuscript is the result of an AZTI's Summer School, celebrated in San Sebastian (Spain), from 5th to 7th June, 2019.-- 19 pages, 3 figures, 2 tables, 1 box ; The integrated study of ocean health and human health is an emerging area of increasing global importance. Growing evidences demonstrate that the health of the ocean and the health of humans have always been and will continue to be, inextricably linked. Our actions toward the oceans will significantly influence the future of the whole planet and, in turn, our own health. The current review of these issues arose from a summer school in San Sebastian (Spain), from 5th to 7th June, 2019. An interdisciplinary group of researchers discussed key risks (e.g., microbial pollution, pharmaceuticals, harmful algal blooms, plastic pollution) and benefits (e.g., bathing waters, recreation, tourism) of the seas and global ocean for humanity; and debated the future priorities and potential actions for a joint Oceans and Human Health research and governance programme in Europe. The aim of this review is to contribute to the emerging scientific agenda on ocean health and human health, as well as coordinate efforts with stakeholders, policy makers and the general public. This agenda operates within the larger context of the upcoming United Nations Decade of Ocean Science for Sustainable Development: 2021–2030, which strives to achieve the Sustainable Development Goals (SDG), including healthy (human) lives and well-being (SDG3) and conserving and sustainably using the oceans (SDG14), among others. In addition to summarizing some of the key risks and benefits, therefore, we describe the governance of oceans and health interactions (especially in Europe), and we finish by proposing a list of elements for potential future research priorities on oceans and human health ; This manuscript is the result of an AZTI's Summer School, celebrated in San Sebastian (Spain), from 5th to 7th June, 2019, funded by AZTI (www.azti.es), the Aquarium of San Sebastian, European Union's Horizon 2020, Grant/Award Number: 774567 (SOPHIE Project https://sophie2020.eu) and 666773 (BlueHealth Project https://bluehealth2020.eu); SCOR and IOC/UNESCO GlobalHAB program (http://www.globalhab.info); the Oceans and Human Health Chair/University of Girona (www.oceanshealth.udg.edu); and the European Environment Agency (EEA). AB was supported through a convention between AZTI and the Basque Water Agency, for monitoring and assess marine waters.

Este artículo contiene 14 páginas, 4 figuras. ; The European Parliament is concerned about the lack of information on the relevance of nine million Europeans engaged in marine recreational fishing (MRF), committing Member States to encourage environmental and socioeconomic sustainability of the sector. The objective of this paper is to provide recommendations to guide research actions and management policies, based on the case of Spain, a key country because its complex administrative regimen and the intensive use of its coasts, including 900,000 recreational fishers. A review of the state of the knowledge was performed to identify research gaps, while governance challenges were identified in an International Symposium on MRF. In the last two decades research on MRF was remarkable (139 publications). However, public investment in research (€2.44 million in the same period) should be improved to cover knowledge gaps on socioeconomic relevance, on impacts on vulnerable species and on implications of global warming. The license system should be standardized to allow estimation of effort, catch and expenditure. Social networks, mobile applications, fisher ecological knowledge, and citizen science programs could help to develop cost-effective research and management. Sciencebased, adaptive policies should improve the allocation of resources between MRF and other stakeholders, introducing co-management to reduce conflicts. ; This work received funds from the Xunta de Galicia under the modality of Grupos de Referencia Competitiva (Grant ED431C2019/11), RECREGES I and II projects under Grants ED481B2014/034-0 and ED481B2018/017, and SICORE project, funded by the Fundación Biodiversidad, Ministerio para la Transición Ecológica, Gobierno de España, Pleamar program, which is cofounded by the European Maritime and Fisheries Fund.

Special issue Oceans and Human Health: The Importance of Marine Ecosystems on Human Health and Wellbeing.-- 17 pages, 5 figures, 1 table, supplementary material https://doi.org/10.3390/ijerph17145078 ; Involving and engaging stakeholders is crucial for studying and managing the complex interactions between marine ecosystems and human health and wellbeing. The Oceans and Human Health Chair was founded in the town of Roses (Catalonia, Spain, NW Mediterranean) in 2018, the fruit of a regional partnership between various stakeholders, and for the purpose of leading the way to better health and wellbeing through ocean research and conservation. The Chair is located in an area of the Mediterranean with a notable fishing, tourist, and seafaring tradition and is close to a marine reserve, providing the opportunity to observe diverse environmental conditions and coastal and maritime activities. The Chair is a case study demonstrating that local, collaborative, transdisciplinary, trans-sector, and bottom-up approaches offer tremendous opportunities for engaging coastal communities to help support long-lasting solutions that benefit everyone, and especially those living by the sea or making their living from the goods and services provided by the sea. Furthermore, the Chair has successfully integrated most of its experts in oceans and human health from the most prestigious institutions in Catalonia. The Chair focuses on three main topics identified by local stakeholders: Fish and Health; Leisure, Health, and Wellbeing; and Medicines from the Sea. Led by stakeholder engagement, the Chair can serve as a novel approach within the oceans and human health field of study to tackle a variety of environmental and public health challenges related to both communicable and non-communicable diseases, within the context of sociocultural issues. Drawing on the example provided by the Chair, four principles are established to encourage improved participatory processes in the oceans and human health field: bottom-up, "think local", transdisciplinary and trans-sectorial, and "balance the many voices" ; The Chair is supported by the Town Council of Roses, the Fisher's Association of Roses, the Fishmongers Guild of Catalonia, and the University of Girona.

This paper provides an overview of the last 40 years of use, and in many cases abuse, of the natural resources in Catalonia, a country that is representative of European countries in general, and especially those in the Mediterranean region. It analyses the use of natural resources made by mining, agriculture, livestock, logging, fishing, nature tourism, and energy production and consumption. This use results in an ecological footprint, i.e., the productive land and sea surface required to generate the consumed resources and absorb the resulting waste, which is about seven times the amount available, a very high number but very similar to other European countries. This overexploitation of natural resources has a huge impact on land and its different forms of cover, air, and water. For the last 25 years, forests and urban areas have each gained almost 3% more of the territory at the expense of agricultural land; those municipalities bordering the sea have increased their number of inhabitants and activity, and although they only occupy 6.7% of the total surface area, they account for 43.3% of the population; air quality has stabilized since the turn of the century, and there has been some improvement in the state of aquatic ecosystems, but still only 36% are in good condition, while the remainder have suffered morphological changes and different forms of nonpoint source pollution; meanwhile the biodiversity of flora and fauna remains still under threat. Environmental policies do not go far enough so there is a need for revision of the legislation related to environmental impact and the protection of natural areas, flora, and fauna. The promotion of environmental research must be accompanied by environmental education to foster a society which is more knowledgeable, has more control and influence over the decisions that deeply affect it. Indeed, nature conservation goes hand in hand with other social and economic challenges that require a more sustainable vision. Today's problems with nature derive from the ...

In late 2019, an outbreak caused by a novel coronavirus started in China (Graham and Baric, 2020; Hu et al., 2020; Maxmen, 2021). A global pandemic was declared in March 2020, as COVID-19, the disease caused by the coronavirus (World Health Organization, 2020b), escalated outside China (World Health Organization, 2020a). In mid-2021, when vaccination campaigns began to show positive effects on the control of the disease in several countries (Kaur and Gupta, 2020), the COVID-19 pandemic caused millions of deaths and hundreds of millions of infections (Dong et al., 2020). To fight the pandemic, governments reacted with measures designed to contain the spread of the virus, especially through measures aimed to reduce social interactions, including lockdowns (Wilder-Smith and Freedman, 2020), travel restrictions (Chinazzi et al., 2020), and limiting people's access to non-essential activities (Storr et al., 2021). Humanity suffered a notable impact as a result of the pandemic, including losses of jobs and an abrupt disruption in global demand of goods and services (Barua, 2020; McKibbin and Fernando, 2020; Nicola et al., 2020). The pandemic further degraded the quality of life of the most vulnerable people, particularly those with mental health problems (Brooks et al., 2020), victims of domestic violence (Usher et al., 2020), children (Singh et al., 2020), or indigenous populations (Lane, 2020). As a result, an increase in economic inequality and worldwide poverty is expected, especially in developing countries (World Bank, 2020), and a peak in the suicide rate (Kawohl and Nordt, 2020). On the other hand, global reduction of human activities has had some positive effects on the global environment, especially for air and water quality (Rutz et al., 2020), and noise reduction (Zambrano-Monserrate et al., 2020). Marine ecosystems for example experienced less impacts derived from commercial fishing due to disruptions in large markets such as the United States (White et al., 2021a) or the European Union (Prellezo and ...
