Fisheries are among the human activities that are most strongly affected by ongoing climate-related changes in the presence and abundance of fish species across the globe. The ecological and social repercussions of such changes for recreational fisheries are however still poorly understood. Here, we explore selected ecological and social dimensions of recreational angling and spearfishing targeting the bluefish (Pomatomus saltatrix) in Italy. The bluefish has undergone a northward expansion in the region over the last 20-30 years, during which it reached new areas and increased in abundance. Using digital videos and their associated data published by recreational fishers on YouTube we characterized ecological and social dimensions using a culturomics approach. Specifically, we focused on harvesting patterns, social engagement and sentiments related to the bluefish. Our study revealed four major results: (i) similar harvesting patterns (i.e., declared mass and seasonal upload patterns) related to videos by recreational anglers and spearfishers; (ii) higher social engagement (i.e., number of views and likes) for videos by recreational anglers than spearfishers; (iii) differences in themes of discussion, with anglers being mainly interested in fishing strategy and gears and spearfishers being more interested in fishing actions shown on the videos; iv) positive and negative sentiments of both recreational anglers and spearfishers towards the invasiveness and aggressiveness of the species. The latter represents an interesting trade-off associated with recreational fishing of the bluefish: it is perceived as an invasive species, but it is also a valued fish target because its voracity contributes to the quality of the recreational fishing experience. Our study showcases the value of exploring social media and associated data to better understand the ecological and human dimensions of marine recreational fisheries in relation to distributional range shifts of species associated with climate change.

<i>Abstract</i> .—There is a need to better understand the perspectives of various recreational fishing stakeholder groups regarding key issues related to fisheries sustainability. To provide a first snapshot and to inform future human dimension studies in this area, we distributed a Web-based open-access survey to fisheries researchers, fisheries managers, and anglers in North America. Attitudes of these respondents towards issues such as overharvest, impacts of catch and release, recreational fisheries management, and research priorities for the future were assessed. We found similar opinions and perspectives by the responding recreational anglers, managers, and researchers on a number of issues, such as the perceived impact of commercial fishing contributing to fish stock declines, the perceived importance of using and promoting gear that minimizes stress and injury to individual fish when fish are to be released, and the belief that conflicts among stakeholders is growing as is the global anti-fishing movement based on animal rights thinking. Differences among responding groups included that researchers tended to be more concerned than anglers and managers with the potential of recreational angling contributing to fish stock declines. Responding anglers were also less content with their involvement in the fisheries management process than were responding managers and researchers, and these anglers also indicated a greater desire for more human dimensions research on understanding angler attitudes and behavior than was evident for responding managers and researchers. This preliminary survey revealed some variation in attitudes among recreational fisheries stakeholders. However, due to lack of random sampling, the study results cannot be extrapolated to the population level. We nevertheless conclude that improved communication and better understanding about the different perspectives among fisheries researchers, managers, and anglers and intrasectorally among different angling groups are needed, particularly when addressing contentious issues of relevance for the entire recreational fishing sector.

Abstract We applied data mining on YouTube videos to better understand recreational fisheries targeting common dentex (Dentex dentex), an iconic species of Mediterranean fisheries. In Italy alone, from 2010 to 2016 spearfishers posted 1051 videos compared to 692 videos posted by anglers. The upload pattern of spearfishing videos followed a seasonal pattern with peaks in July, a trend not found for anglers. The average mass of the fish declared in angling videos (6.4 kg) was significantly larger than the one in spearfishing videos (4.5 kg). Videos posted by spearfishers received significantly more likes and comments than those posted by anglers. Content analysis suggested that the differences in engagement can be related to appreciation of successful spearfishers necessitating relevant personal qualities for catching D. dentex. We also found that the mass of the fish positively predicted social engagement as well as the degree of positive evaluation only in spearfishing videos. This could be caused by the generally smaller odds of catching large D. dentex by spearfishing. Our case study demonstrates that data mining on YouTube can be a powerful tool to provide complementary data on controversial and data-poor aspects of recreational fisheries and contribute to understanding the social dimensions of recreational fishers.

The Impact

The economic and harvest impacts of Marine Recreational Fishing (MRF) in Çanakkale Strait were analysed along with fishing policy, sociology and habits of fishers. Data sources included field survey data carried out along the entire length of the Çanakkale strait and policy information gathered from published sources. MRF policy is commendable, even in the fishing tourism sector, and is better developed than that in many other European countries. In Çanakkale, 9.9% of the population is recreational fishers. Recreational fishers are typically men (90%), primarily those between the ages of 25 and 49 yrs. The occupation of the recreational fishers ranged from self-employed (28%), students (28%), retired persons (22%) and public employees (15%), to currently-unemployed persons (7%). An analysis of diel behaviour showed that most recreational fishers preferred fishing during the day (56.1%), while the evening was the next most preferred time for fishing (18%), followed by the night-time (9.8%), while a substantial number of recreational fishers (16.1%) reported that they fished at any time of day. The most popular type of fishing was shore-based (68%), followed by boat-based (21%), and underwater fishing (11%). The mean daily fishing times were 6.07 h d-1, 6.18 h d-1 4.75 d-1 for boat-based, underwater and shore-based fishing, respectively. Summer and autumn were the preferred seasons for shore-based and underwater fishing, while autumn and winter were preferred for boat-based fishing. The highest Catch per Unit Effort (CPUE) was observed for boat-based fishing (2.77 kg h-1), followed by underwater (0.97 kg h-1) and shore-based fishing (0.81 kg h-1). The catch composition included 51 species, though the catch composition of each fishing type was mostly comprised of only 3 or 4 species. The impact of the MRF harvest was high (30% of commercial fishing), particularly for bluefish (Pomatomus saltatrix) and picarel (Spicara smaris) species. The economic impact of MRF was highly negative. Several indicators including the following revealed a high percentage of trading catch (47%) being conducted under the guise of a recreational label: annual fishing intensity, total costs, target species, and sales. At present, it is evident that the highly developed recreational fishing policy in Turkey is not sufficient to ensure that recreational fishing is sustainable or to prevent fishing conflicts in Turkey. This study revealed the need for establishing monitoring, control and surveillance programs to ensure the sustainability of fish resources and fisheries including MRF.

AbstractSixty officers of the fisheries guard from three regions in northeast Poland, an area that is rich in inland waters, were surveyed. The results obtained are presented as percentages of each possible answer to each question and as rankings on a five-point scale. Those surveyed reported that the most common motivation for serving in the guard was an interest in nature, followed by an interest in recreational fisheries and then their own material and living conditions. Those surveyed reported that the principal motivation for poaching was to earn profits and as a consequence of unemployment. Sixty percent of officers reported encountering aggression from those who were monitored. Ninety percent of officers reported receiving threats from those monitored. The officers surveyed ranked their professional experience the highest among factors that impacted the effectiveness of the activities performed by the fisheries guard and the possibility of safeguarding ichthyofauna against poaching.

Assessing the motivations and wildlife-related value orientations (WVOs) of outdoor recreations, such as recreational fishing (RF), is of key importance to understand the human dimensions of natural resource use and to inform management actions. Using a national random telephone survey, we contrasted the participation rate, the socio-economical profile, and the motivations and WVO of the participants of RF, outdoor recreation (OR), consumptive outdoor recreation (COR), and indoor recreation (IR) in Spain. Participation rates of the four subgroups were 6.6, 15.3, 49.4, and 28.4%, for RF, COR, OR, and IR, respectively. The four subgroups differed in socio-economic characteristics, with women being substantially less involved in RF compared to COR, OR, and IR. Moreover, we found higher incomes and educational degrees of the participants in the three outdoor modalities compared to IR. Motivations to engage in RF, COR, OR, and IR were different. Recreational fishers placed significantly more importance on the motives “to be close to nature,” “to experience tranquility,” “to get away from the usual demands of life,” “to relax psychically,” “to stay with family,” and “to get exercise” compared to the other recreational groups, being very different from the ones to practice IR. We did not find significant differences in the WVO among the participants of the four recreational activities. We conclude that recreational fishing is a widespread recreational activity in Spain, embedded in all the segments of the society, thereby generating substantial psychological benefits, which are not equally produced by other forms of indoor and outdoor recreation.

Handling Practices

Bycatch in fisheries is a well-explored topic, although less so in recreational fisheries. We encountered frequent bycatch of Mudpuppy (Necturus maculosus), a neotenic aquatic salamander that is active in winter, in passively baited ice-fishing gear targetting teleost fishes. We noted hook location in Mudpuppies captured by two hook types: J-hooks and circle hooks. Our prediction was that circle hooks would reduce the frequency of deep hooking of Mudpuppies, which is often cited as an important predictor of post-release mortality in fishes. We found no difference in the frequency of deep hooking of Mudpuppies captured by circle or J-hooks, although, in a subset of Mudpuppies (n = 13) held for 24 h after capture, one death occurred (8%). Further research may be necessary to determine whether deeply hooked Mudpuppies can pass or shed hooks and survive beyond the 24-h period we monitored. However, our findings suggest that anglers and managers should consider refinements to handling practices for Mudpuppies captured as bycatch, because they are likely to survive if handled cautiously. These results, which are among the first describing non-fish bycatch in recreational fisheries, call for managers and anglers who encounter Mudpuppies during recreational fishing to seek more information and educational opportunities to improve the fate of this important component of temperate freshwater ecosystems and ecological indicator speciesthat is incidentally captured by ice fishing.

SUMMARYOverfishing is a mounting threat to marine ecosystems and food security worldwide. Recreational fisheries are poorly understood and pose governance challenges due to the scarcity of monitoring data. The impact of recreational spearfishing on eastern blue groper (Achoerodus viridis) and grey nurse shark (Carcharias taurus) in Australia was analysed by assessing a chronology of spearfishing publications for historical, ecological and social data. Reported captures of blue groper declined by 90% from 1952–1967. Grey nurse shark captures also declined. Interestingly, early warnings of declines for both species emerged from the spearfishing community 17 and 19 years, respectively, before protection. While recreational fishers may have serious impacts on vulnerable fish species, they could also play a vital role in conservation and advocacy. This highlights the importance of reciprocal communication between fishers, scientists and governments for managing and detecting declines in vulnerable species.

The 1960S

Despite the increasing importance of marine recreational fishing, recreational fisheries management is often hampered by lack of adequate data and limited effectiveness of conventional regulations. In Shark Bay, Western Australia, snapper (Pagrus auratus) in the Eastern Gulf, Denham Sound and Freycinet Estuary have been a major attraction for recreational fishers since the 1960s. Various management measures were progressively introduced from 1998 onwards to limit snapper catches, including increases in minimum length, introduction of a maximum length, reductions in daily bag limit, a moratorium in the Eastern Gulf (June 1998–March 2003), a 6-week spawning closure in the Freycinet Estuary and, finally, the introduction of a Total-Allowable-Catch-based system in 2003. Stock assessments in 2011 indicated that spawning biomass in the Eastern Gulf and Denham Sound had rebuilt to the management target level while biomass in the Freycinet Estuary remained below the threshold level but was continuing to slowly rebuild. This paper summarising the research and adaptive management of the snapper fishery over the last 15+ years represents an important case study that addresses a range of issues typically associated with marine recreational fisheries, including assessment of stock size and recreational catch, evaluation of management regulations and active engagement with the recreational fishing community.

Abstract Sport and recreational marine fishery can significantly contribute to the national budget through its economic and social effects. The main aim of this research is to define the economic and social significance of sport and recreational fishing in Croatia through the assessment of the lower limit of its economic value. This is done by analyzing the segments of sport and recreational fishing together with the economic and other activities which are closely related to it. When expressed by the number of stakeholders involved in sport and recreational fisheries and the share in the gross domestic product, it can be concluded that the economic effects of these activities are only slightly lower than in commercial fisheries. This research provides the groundwork for pointing out the basic guidelines of the social significance of sport and recreational marine fishery in Croatia. Hence, it can be noted that sport and recreational fishing in local coastal communities support the overall development of rural areas and the local communities in particular.
