- First assessment of the Impacts of the COVID-19 pandemic on global marine recreational fisheriesPublication . Pita, Pablo; Ainsworth, Gillian B.; Alba, Bernardino; Anderson, Antônio B.; Antelo, Manel; Alós, Josep; Artetxe, Iñaki; Baudrier, Jérôme; Castro, José J.; Chicharro, Belén; Erzini, K; Ferter, Keno; Freitas, Mafalda; García-de-la-Fuente, Laura; García-Charton, José A.; Giménez-Casalduero, María; Grau, Antoni M.; Diogo, Hugo; Gordoa, Ana; Henriques, Filipe; Hyder, Kieran; Jiménez-Alvarado, David; Karachle, Paraskevi K.; Lloret, Josep; Laporta, Martin; Lejk, Adam M.; Dedeu, Arnau L.; Martín-Sosa, Pablo; Martínez, Lllibori; Mira, Antoni M.; Morales-Nin, Beatriz; Mugerza, Estanis; Olesen, Hans J.; Papadopoulos, Anastasios; Pontes, João; Pascual-Fernández, José J.; Purroy, Ariadna; Ramires, Milena; Rangel, Mafalda; Reis-Filho, José Amorim; Sánchez-Lizaso, Jose L.; Sandoval, Virginia; Sbragaglia, Valerio; Silva, Luis; Skov, Christian; Sola, Iván; Strehlow, Harry V.; Torres, María A.; Ustups, Didzis; van der Hammen, Tessa; Veiga, Pedro; Venerus, Leonardo A.; Verleye, Thomas; Villasante, Sebastián; Weltersbach, Marc Simon; Zarauz, LucíaIn 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 Carvahlo, 2020; Coll et al., 2021).
- High-density SNP panel provides little evidence for population structure in European sea bass (Dicentrarchus labrax) in waters surrounding the UKPublication . Taylor, Martin I.; Lamb, Philip D.; Coscia, Ilaria; Murray, David S.; Brown, Mary; Cameron, Tom C.; Davison, Phil I.; Freeman, Howard A.; Georgiou, Katerina; Grati, Fabio; Haugen, Thrond; Karachle, Paraskevi K.; Kennedy, Richard; Lanssens, Thomas; Lincoln, Harriet; Martinho, Filipe; McCarthy, Ian; Petroutsos, Spyros-Iasonas; Pita, Pablo; Pontes, João; Baucells, Marta P.; Rangel, Mafalda; Roche, William; Sbragaglia, Valerio; Sturrock, Anna M; Taylor, Michelle L; Wogerbauer, Ciara; Veiga, Pedro; Verver, Sieto; Weltersbach, Marc Simon; Hyder, Kieran; Stewart W GrantThe European sea bass (Dicentrarchus labrax) is a commercially and recreationally important fish widely, distributed across the Northeast Atlantic Ocean and Mediterranean Sea. Two distinct lineages that represent the Atlantic and Mediterranean regions have been previously identified, with a hybrid zone close to the Almeria-Oran front. The presence of fine-scale population structure within the Northeast Atlantic region is less clear. Here, we investigated population structure in adult samples obtained from the northern part of the Atlantic range surrounding the UK, Ireland, Belgium, Germany, France, the Netherlands, and Norway, along with outgroups from Portugal and the Mediterranean, using a panel of 41 K single nucleotide polymorphism markers. Population structure among Northeast Atlantic Ocean samples was weak in both spawning-(FST = 0.00022) and feeding-(FST = 0.00032) season data sets, with small pairwise FST values between sample pairs. However, average FST was larger between spawning samples than between feeding samples, with a pattern of isolation-by-distance among the spawning samples, but not the feeding samples, suggesting some biologically meaningful population structure. The largest pairwise FST values at both International Council for the Exploration of the Sea (ICES) rectangle and division scales involved a sample from the west of Ireland. We found no evidence of a gradient in "Mediterranean" ancestry among samples collected around the UK in our data set or in a reanalysis of a published data set where such a pattern had been previously identified. In summary, there was no evidence that sea bass in different ICES divisions within the Northeast Atlantic Ocean represents genetically separate populations. Further work is required to reconcile evidence from tagging and modelling studies that suggest the potential for demographic independence with the genetic data.
- Recreational sea fishing in Europe in a global contextParticipation rates, fishing effort, expenditure, and implications for monitoring and assessmentPublication . Hyder, Kieran; Weltersbach, Marc Simon; Armstrong, Mike; Ferter, Keno; Townhill, Bryony; Ahvonen, Anssi; Arlinghaus, Robert; Baikov, Andrei; Bellanger, Manuel; Birzaks, Janis; Borch, Trude; Cambie, Giulia; de Graaf, Martin; Diogo, Hugo M.

Although reporting MRF catches is a European Union legislative requirement, estimates are only available for some countries. Here, data on numbers of fishers, participation rates, days fished, expenditures, and catches of two widely targeted species were synthesized to provide European estimates of MRF and placed in the global context. Uncertainty assessment was not possible due to incomplete knowledge of error distributions; instead, a semi-quantitative bias assessment was made. There were an estimated 8.7 million European recreational sea fishers corresponding to a participation rate of 1.6%. An estimated 77.6 million days were fished, and expenditure was Euro5.9 billion annually. There were higher participation, numbers of fishers, days fished and expenditure in the Atlantic than the Mediterranean, but the Mediterranean estimates were generally less robust. Comparisons with other regions showed that European MRF participation rates and expenditure were in the mid-range, with higher participation in Oceania and the United States, higher expenditure in the United States, and lower participation and expenditure in South America and Africa. For both northern European sea bass (Dicentrarchus labrax, Moronidae) and western Baltic cod (Gadus morhua, Gadidae) stocks, MRF represented 27% of the total removals. This study highlights the importance of MRF and the need for bespoke, regular and statistically sound data collection to underpin European fisheries management. Solutions are proposed for future MRF data collection in Europe and other regions to support sustainable fisheries management.
- Research and management priorities for Atlantic marine recreational fisheries in Southern EuropePublication . Pita, Pablo; Artetxe, Inaqui; Diogo, Hugo; Gomes, Pedro; Gordoa, Ana; Hyder, Kieran; Pereira, Joao; Pita, Cristina; Rangel, Mafalda; Garcia-Rodrigues, Joao; Sague, Oscar; Veiga, Pedro; Vingada, Jose; Villasante, SebastianMarine Recreational Fishing (MRF) is an important activity in Europe, with 9 million fishers and generating annually 6 billion in direct expenditures. However, there is a lack of data and understanding of MRF in Europe, particularly in Southern countries, which prevents a number of fish stocks from being effectively assessed and managed. In November 2016, a participatory workshop on MRF was held in Vigo (Spain) to identify challenges and opportunities for data collection, and to diagnose key research gaps and management issues for MRF in the Southern European Atlantic. Experts from a wide range of disciplines (researchers, policy makers, fisheries managers and commercial and recreational fishers) highlighted that the management of MRF is a challenge due to complex and dispersed legal frameworks, with multiple administrations involved, and overlapping uses of space with commercial fishing, aquaculture, navigation and tourism, among others. The lack of strong and representative fishing associations hampers research and management initiatives. Effective communication between recreational fishers, researchers and fisheries managers is also lacking. Despite the ecological, social and economic relevance of MRF, there is no systematic and comprehensive collection of information on fishing effort, recreational catches, expenses, social profile and access conditions of European recreational fishers. These data would be useful to avoid biases in the assessment of recreational fisheries due to the great diversity of ecosystems, species and typologies of users. Strategic recommendations and research priorities were also identified to address knowledge gaps and are discussed in the context of the management of MRF across Europe.
- Staying hooked: effective science engagement and communication in recreational fisheriesPublication . Pita, Pablo; Tracey, Sean; Arlinghaus, Robert; Bachiller, Eneko; Pinho-Duarte, Filipa; Ferter, Keno; Henriques, Filipe; Hook, Samantha; Hyder, Kieran; Irigoyen, Alejo; Jiménez, María P.; Laporta, Martín; Lejk, Adam M.; Leonard, Eoin; Olesen, Hans Jakob; Palmer, Freya; Pavičić, Mišo; Pontes, João; Pujol-Baucells, Marta; Radford, Zachary; Rangel, Mafalda; Roche, William; Rudd, Hannah; Ryan, Diarmuid; Sbragaglia, Valerio; Selles, Jules; Silva, Catarina N. S.; Skov, Christian; Strehlow, Harry V.; Taylor, Stephen; Veiga, Pedro; Venerus, Leonardo A.; Venturelli, Paul; Vertegaal, David; Weltersbach, Marc Simon; Wiech, Martin; Winkler, AlexanderThis abstract summarizes the results of two expert consultations conducted to gather insights into effective communication and engagement strategies in recreational fisheries. Effective science communication fosters knowledge, understanding, and trust in both science and management decisions. Public involvement and stakeholder engagement are essential for effective management. Simplifying complex research findings and using diverse communication tools enhance awareness and understanding. Strong communication strategies are necessary to implement sustainable recreational fisheries management frameworks. Funding for communication efforts is often insufficient but remains crucial for success. Participatory workshops and data-sharing arrangements enhance collaboration and involvement. Multi-stakeholder consortiums and tailored communication strategies strengthen stakeholder engagement and promote adaptive governance. Interdisciplinary outreach and strategic social media use play vital roles in raising environmental awareness.
- Unexpectedly high catch-and-release rates in European marine recreational fisheries: implications for science and managementPublication . Ferter, Keno; Weltersbach, Marc Simon; Strehlow, Harry Vincent; Vølstad, Jon Helge; Alós, Josep; Arlinghaus, Robert; Armstrong, Mike; Dorow, Malte; de Graaf, Martin; van der Hammen, Tessa; Hyder, Kieran; Levrel, Harold; Paulrud, Anton; Radtke, Krzysztof; Rocklin, Delphine; Sparrevohn, Claus Reedtz; Veiga, PedroWhile catch-and-release (C&R) is a well-known practice in several European freshwater recreational fisheries, studies on the magnitude and impact of this practice in Europeanmarine recreational fisheries are limited. To provide an overview of the practice andmagnitude of C&R among marine recreational anglers in Europe, the existing knowledge of C&R and its potential associated release mortality was collected andsummarized. The present study revealed that in several European countries over half of the total recreational catch is released by marine anglers. High release proportions of > 60% were found for Atlantic cod (Gadus morhua), European sea bass (Dicentrarchus labrax), pollack (Pollachius pollachius), and sea trout (Salmo trutta) in at least one of the studied European countries. In the case of the German recreational Baltic Sea cod fishery, release proportions varied considerably between years, presumably tracking a strong year class ofundersized fish. Reasons for release varied between countries and species, and included legal restrictions (e.g. minimumlanding sizes and daily bag limits) and voluntary C&R. Considering the magnitude of C&R practice among European marine recreational anglers, post-release mortalities of released fish may need to be accounted for in estimated fishingmortalities.However, as the survival rates of Europeanmarine species aremostly unknown, there is a need to conduct post-release survival studies and to identify factors affecting post-release survival. Such studies could also assist in developing species-specific, best-practice guidelines to minimize the impacts of C&R on released marine fish in Europe.
