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).
- A global review of marine recreational spearfishingPublication . Sbragaglia, Valerio; Arlinghaus, Robert; Blumstein, Daniel T.; Diogo, Hugo; Giglio, Vinicius J.; Gordoa, Ana; Januchowski-Hartley, Fraser Andrew; Laporta, Martín; Lindfield, Steven J.; Lloret, Josep; Mann, Bruce; McPhee, Daryl; Nunes, José A. C. C.; Pita, Pablo; Rangel, Mafalda; Rhoades, O. Kennedy; Venerus, Leonardo A.; Villasante, SebastiánRecreational spearfishing is a fishing method that occurs globally, yet receives considerably less attention in the scientific literature relative to other recreational fishing methods, such as angling. Lack of scientific information on spearfishing may negatively affect the development and management of marine recreational fisheries. We conducted a systematic review of 102 peer-reviewed papers published between 1967 and 2022 pertaining to marine recreational spearfishing. Based on this literature review, we provide an overview of key insights across social, economic, and ecological dimensions of marine recreational spearfishing. While spearfishers represent less than 5% of marine recreational fishers, the participants are younger and may differ from recreational anglers in their motivations, with suggestions of increased well-being generated from a close connection with the sea during underwater fishing. Recreational spearfishers mostly target species of moderate to high levels of vulnerability that are mid to high trophic level carnivores. Though spearfishers can deliberately target larger individuals of exploited populations, this is not a generalizable pattern. Despite a growing body of research on the ecological impacts of marine recreational spearfishing, there is limited knowledge of these effects and their mechanisms across biological levels of organization (e.g., individual, population, community and ecosystem) compared with those of other fishing methods. Recreational spearfishers can contribute to advances in marine ecological knowledge, and inclusive participatory management could represent a key step towards transformative sustainable development of marine recreational spearfishing. Throughout the review, we identify gaps in the research and areas where future research is needed to better inform the socio-economic importance, ecosystem impacts and future management of marine recreational spearfishing.
- Linking size-based trophodynamics and morphological traits in marine fishesPublication . Rios, Maria F.; Venerus, Leonardo A.; Karachle, Paraskevi K.; Reid, William D. K.; Erzini, Karim; Stergiou, Konstantinos I.; Galvan, David E.The rule of thumb in marine trophodynamics indicates that the bigger an organism, the higher its trophic level (TROPH). This generalization leads to the assumption that fishes increase their TROPH with growth. However, a recent review showed that for many species, TROPH does not increase with body size, suggesting that size-independent feeding is not rare in marine fishes. Here, we assessed some morphological traits of marine fishes that could potentially be used as indicators for the ability to vary TROPH with body size. Stable isotope values of nitrogen were used as a proxy TROPH. The specific objectives were as follows: (a) to evaluate the relationship between the oral gape and the trophodynamic trend and (b) to quantify the relevance of 11 external morphological traits in determining the size-based trophodynamics. We used random forest models to identify the morphological traits that would help predict which species would have the potential to increase TROPH with growth and which would have not. The selected traits included the pelvic fin relative position, the dorsal fin shape, total length, and relative mouth size. Our results also showed a marked relationship between the rate of increase in the oral gape and TROPH. The analyses presented here provide the first comprehensive and quantitative review aiming at linking the trophodynamics of marine fishes with external morphological traits.
- 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.
