La pesca recreativa a la costa catalana : Guia d'espècies

La pesca marítima recreativa és una activitat amb una llarga tradició, fortament arrelada al litoral Mediterrani. A Catalunya, els més de 550 km de costa, juntament amb la diversitat geomorfològica del nostre litoral, contribueixen a que hi hagi un gran nombre de practicants de pesca recreativa. En base a un estudi recent realitzat per la DGPAM (2020), s'estima que a Catalunya hi ha prop de 54.000 pescadors recreatius que practiquen almenys una de les tres modalitats: costa, embarcació o submarina. Com d'altres activitats humanes, la pesca recreativa és una font de pressió sobre el medi marí i els seus impactes sobre els recursos biològics i els ecosistemes on habiten han de ser considerats. Donat l'interès de l'administració pesquera catalana, així com de la comunitat de pescadors recreatius catalans perquè l'activitat pugui practicar-se de forma sostenible, aquesta guia aporta informació sobre les espècies objectiu de l'activitat, amb la finalitat de promoure hàbits de pesca responsables. La guia presenta il·lustracions per a 65 espècies objectiu i dona informació pràctica sobre les seves característiques biològiques, ecològiques i legals, per a millorar-ne el coneixement i promoure una activitat més sostenible a llarg termini, en benefici de tots. Diverses de les espècies de la guia són especialment vulnerables, sobre les quals cal tenir una conscienciació especial. Les espècies vulnerables es caracteritzen per tenir un creixement lent i una longevitat elevada, o bé per tenir un potencial reproductor baix, o bé per estar incloses en els convenis internacionals de protecció de la biodiversitat. Aquesta guia de butxaca pretén ser una eina útil per facilitar la identificació i la comparació d'algunes espècies objectiu i per conèixer més sobre el seu estat actual. La participació i col·laboració del pescador recreatiu és essencial per mantenir la compatibilitat entre la pesca recreativa i els recursos marins.Recomanacions de bones pràctiques: - No capturar més individus dels necessaris. Retenir només aquells que hagin de ser consumits en un entorn familiar i d'amics; la resta caldria alliberar-los vius al mar. - Respectar les talles mínimes, juvenils i espècies vulnerables i protegides.- Evitar l'ús d'hams petits per ajudar a disminuir les captures d'individus per sota la talla mínima legal o talla de primera maduresa. - En cas de pescar individus durant la seva etapa reproductora, es recomana la solta del peix viu a l'aigua, procurant tenir l'animal el mínim temps possible fora de l'aigua i intentant no malmetre'l al treure-li l'ham. - Si es desitja conservar la captura d'una espècie vulnerable, s'aconsella pescar un únic individu de la mateixa espècie a cada jornada de pescaPeer reviewe

The first estimates of species compositions of Spanish marine recreational fishing reveal the activity’s inner and geographical variability

Este artículo contiene 9 páginas, 5 figuras, 1 tabla.This study represents the first nationwide assessment of marine recreational fishing catch compositions in Spain. Catch data from 7848 recreational fishers were collected using an online survey that was conducted from February 2016 to February 2017. The major modalities of the recreational fishing sector: shore fishing, boat fishing, and spearfishing were analysed independently in each Spanish coastal Autonomous Community (AC). The results revealed the high variability in the species compositions among modalities, as well as between the ACs, which showed spatial trends grouping them into larger regional units. For all three modalities, the Mediterranean and Atlantic AC were grouped separately. The Canary Islands were classified alone, except for the boat fishing modality, for which they were grouped with the Balearic Islands forming an archipelago group. Our results show the considerable heterogeneity in recreational fishing, and evidence for the need to study each modality as a separate compartment of a wider activity, and the risks of spatial extrapolations.This research has been funded by the Spanish National Research Council, Proyecto intramural 201530E060.Peer reviewe

Recreational fishing in Spain: First national estimates of fisher population size, fishing activity and fisher social profile

Este artículo contiene 12 páginas, 7 figuras, 2 tablas.This study represents the first nationwide assessment of marine recreational fishing in Spain. A new cost-effective approach was used to collect fisher’s information: an online application adapted to different platforms was kept operative from February 2016 to February 2017. Commercial and non-commercial dissemination campaigns represented substantial differences in their success rate and cost-effectiveness. In this study, fisher’s population size, profile and fishing activity were analysed for shore fishing, boat fishing and spearfishing independently in each of Spain’s Autonomous Communities (AC). The official recreational fishing population according to the license registries reported by the AC is of 871,533 fishers, but this study reveals that around 5% of fishers are unlicensed. The most popular modality was shore fishing (83.6% to 67% of recreational fishers) followed by boat-fishing (11% and 31%) and spearfishing (1.2% to 4.9%). The mean age varied significantly between modalities: 36 years for spearfishing, 41 years for shore fishing and 45 years for boat fishing. The education level of spear-fishers and boat-fishers were both higher than that of shore-fishers, which had the highest levels of unemployment. Fisher satisfaction levels of the activity and the catch were high for every modality and AC. Interestingly, a 94% of our respondents declared that their catch was for household consumption. Catch rates differed significantly between fishing modalities: shore fishing had the lowest catch rates (1.17 kg d−1s.e. 0.028), followed by spearfishing (2.02 kg d−1 s.e. 0.044) and boat fishing (2.91 kg d−1 s.e. 0.78). Estimates of annual fishing days (shore fishing 60.6 d y−1 s.e. 0.67; boat fishing 57.1 d y−1 s.e. 0.092; spearfishing 51.5 d y−1 s.e. 0.71) did not differ from those of previously published studies using onsite surveys in the same regions, despite the fact that our sample could be potentially over-representing avid fishers. The implications of misestimating annual effort and its importance on MRF impact are also discussed.This research has been funded by The Spanish National Research Council, Proyecto intramural 201530E060.Peer reviewe

Characterizing the Profile of Recreational Fishers Who Share Their Catches on Social Media

12 pages, 8 figures, 2 tables, supplementary material https://www.frontiersin.org/articles/10.3389/fmars.2021.768047/full#supplementary-material.-- Data Availability Statement: The raw data supporting the conclusions of this article will be made available by the authors, without undue reservationSocial media may provide information for monitoring recreational fisheries, but several caveats prevent operationalization. Specifically, the fraction and profile of recreational fishers sharing their catches is not known. Our aim was to advance the monitoring capacities of recreational fishing using social media data. We collected data with onsite (face-to-face) survey and online (emails) questionnaires to characterize marine recreational fishers sharing catches on digital platforms (“sharers”) along with other demographic or fishing information. In the online survey we found that 38% of recreational fishers share their catches using digital platforms (including the private messaging platform WhatsApp), but such proportion dropped to 12% when considering only public or semi-public social media (Instagram was the most commonly used platform, followed by Facebook, YouTube, and Twitter). A similar pattern was found with the online questionnaire where sharers represented 37% of recreational fishers (including WhatsApp), while such proportion dropped to 21% when considering only public or semi-public social media. In general, sharers were more avid (24 and 35 yearly fishing trips for onsite and online survey, respectively) compared to non-sharers (18 and 31 yearly fishing trips). Sharers also spent more money on each fishing trip (on average 26 and 31 euro for onsite and online survey, respectively) than non-sharers (on average 21 and 28 euro for onsite and online survey, respectively), but they had similar chances of catching something. However, for fishers with catches, the harvest per unit effort of sharers was higher than that of non-sharers (0.4 and 0.5 kg/h with respect to 0.3 and 0.4 kg/h, for onsite and online survey, respectively). Moreover, recreational fishers that caught trophy, iconic, or emblematic species were more inclined to share their catches.

Describing properties of littoral habitats from NW Mediterranean rocky shores through co-occurrence network analysis

Este artículo contiene 14 páginas, 8 figuras, 2 tablas.Littoral habitats are commonly defined by environmental properties and the presence of certain dominant species. This conception relies on species’ frequencies and/or abundances, but often omits co-occurrence relationships. In an effort to incorporate this information, we here used presence-absence data from visual censuses of 16 mediolittoral habitats from North-western Mediterranean Sea rocky shores to build co-occurrence networks. These were compared to networks built using species frequency data. Network analyses were done for the entire mediolittoral zone as a unit, and for each habitat individually. For each habitat, network topology revealed central hubs of highly co-occurring species that scored high in degree and eigenvector centrality, essentially corresponding to the most frequent species, both in the mediolittoral zone as a whole and within each of the habitats. Many species, however, co-occurred disproportionately to their frequencies, which highlights the relevance of co-occurrence estimations for habitat descriptions. Some habitats had clear modules as separate habitat subunits. Values of Shannon-Wiener diversity and evenness were well associated with most network metrics, but not with graph density, which helped uncover inhomogeneous species relationships within a same habitat throughout the sampling sites. The habitat features observed mostly supported current phytosociological subdivisions. This stresses the importance of network tools for depicting and describing habitat types, as they provide complementary information to conventional descriptions and may help identify habitat sub-groups, or to define unclassified habitats.Financial support to this research came from the projects “Cartografia dels Habitats ` Litorals a Catalunya” (Departament de Territori i Sosteniblitat and Institut Cartografic, ` Generalitat de Catalunya) and CTN1500528 of the Ag`encia Catalana de l’Aigua.

First Assessment of the Impacts of the COVID-19 Pandemic on Global Marine Recreational Fisheries

This work is the result of an international research effort to determine the main impacts of the COVID-19 pandemic on marine recreational fishing. Changes were assessed on (1) access to fishing, derived from lockdowns and other mobility restrictions; (2) ecosystems, because of alterations in fishing intensity and human presence; (3) the blue economy, derived from alterations in the investments and expenses of the fishers; and (4) society, in relation to variations in fishers’ health and well-being. For this, a consultation with experts from 16 countries was carried out, as well as an international online survey aimed at recreational fishers, that included specific questions designed to capture fishers’ heterogeneity in relation to behavior, skills and know-how, and vital involvement. Fishers’ participation in the online survey (5,998 recreational fishers in 15 countries) was promoted through a marketing campaign. The sensitivity of the fishers’ clustering procedure, based on the captured heterogeneity, was evaluated by SIMPER analysis and by generalized linear models. Results from the expert consultation highlighted a worldwide reduction in marine recreational fishing activity. Lower human-driven pressures are expected to generate some benefits for marine ecosystems. However, experts also identified high negative impacts on the blue economy, as well as on fisher health and well-being because of the loss of recreational fishing opportunities. Most (98%) of the fishers who participated in the online survey were identified as advanced, showing a much higher degree of commitment to recreational fishing than basic fishers (2%). Advanced fishers were, in general, more pessimistic about the impacts of COVID-19, reporting higher reductions in physical activity and fish consumption, as well as poorer quality of night rest, foul mood, and raised more concerns about their health status. Controlled and safe access to marine recreational fisheries during pandemics would provide benefits to the health and well-being of people and reduce negative socioeconomic impacts, especially for vulnerable social groups

Primeira avaliação dos impactos da pandemia COVID-19 sobre pesca recreativa marinha global

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 Carvahlo, 2020; Coll et al., 2021).info:eu-repo/semantics/publishedVersio
