Introducing disciplinary perspectives and interdisciplinary possibilities for studying recreational fishers and fisheries

Individuals from many disciplines conduct research to understand the social dimension of recreational fisheries. This diverse inquiry has produced a comprehensive understanding of the behaviours of recreational fishers, the outcomes from fishing, and the relationships among fishers, others, and the natural and human environment. The associated body of research, however, is largely disconnected across disciplines. Our goals here are to help readers understand the similarities and differences among disciplines and to identify opportunities for interdisciplinary-based research on recreational fishers. Before addressing these goals, we begin by answering basic questions: What is a discipline? What are the primary disciplines used to study recreational fishers? And what is the genealogy of research on recreational fishers? Seven key disciplines are then classified by multi-criteria related to both focus and epistemological and methodological approaches. This classification reveals clear connections among: (i) ecological science and resource economics, and to a lesser extent historical ecology; (ii) environmental history and political ecology; and (iii) behavioural economics and social psychology. We next describe and provide possible remedies for barriers that inhibit interdisciplinary research, including different epistemologies, nomenclature, and reward bias. Finally, we highlight opportunities to conduct interdisciplinary research by describing the types of benefits that each discipline can provide when conducting interdisciplinary research on recreational fisheries.

Examining landowners’ preferences for a chronic wasting disease management program

Private landowners are key partners in chronic wasting disease (CWD) management, especially in landscapes where there is limited public ownership. In this study, we evaluated landowners' preferences for alternative hypothetical CWD management programs using a stated choice experiment. We were particularly interested in understanding preferences for the use of financial incentives to motivate white-tailed deer harvest and facilitate hunter access to private lands as potential CWD management tools. We used latent class analysis to characterize preference heterogeneity among landowners stemming from patterns of choice. We compared means and distributions of auxiliary variables related to landowners' perceived risks, trust, attitudes toward management, and sociodemographics across latent classes stemming from choice model results. The pooled model demonstrated that reducing deer population density, providing payments to landowners for CWD-positive deer taken from their property, the form of incentives for public access, and banning recreational deer feeding had a small positive effect on respondents' choice of CWD management program. However, providing financial payments to hunters for harvesting CWD-positive deer and the use of targeted culling had the opposite effect on choice. Latent class models revealed that a majority of respondents exhibited a pattern of preference where all forms of incentives exerted a negative effect on choice, but smaller subsets of landowners positively evaluate the use of some incentives. Post-hoc contrasts revealed relationships between patterns of preferences and trust, risk, and attitudes toward CWD management with small to medium effects. Results demonstrated limited support for the use of financial incentives as a tool to manage access and harvest in the southeast Minnesota CWD management zone

On the multiple identities of stakeholders in wolf management in Minnesota, United States

Social identity theory offers a means to understand attitudes about wolves, with consequences for management support. Using data from a mail survey about wolves, we explored relationships among seven identities (i.e., wolf advocate, hunter, environmentalist, nature enthusiast, farmer, trapper, conservationist) using multidimensional scaling (MDS) and principal components analysis (PCA). We examined how identities correlated with political ideology, trust in a wildlife management agency, wildlife value orientations (WVOs) and attitudes about wolves, and we evaluated whether WVOs mediated the relationship between identities and attitudes. PCA suggested two factors in identifying relationships among stakeholders, while MDS and correlations found diversity among stakeholders beyond these factors. Hunter identity was most strongly associated with a domination WVO and conservative political ideology. Farmer identity was most strongly associated with agency distrust and negative wolf attitudes. Wolf advocate was most strongly associated with a mutualism WVO (i.e., beliefs that humans are meant to coexist in harmonious relationships with wildlife), agency trust, and positive wolf attitudes. Conservationist identity was positively correlated with all other identities. WVOs partially mediated the relationship between identities and attitudes.

Cognitive and behavioral coping in response to wildlife disease: The case of hunters and chronic wasting disease

The transactional model of stress and coping (TMSC) provides a conceptual framework for understanding adaptations to stressors like chronic wasting disease (CWD). Understanding hunter response to stressors is important because decreased participation and satisfaction can affect individual well-being, cultural traditions, agency revenue, and local economies. Using TMSC, we explored how deer hunters coped with CWD. We also compared involvement, and impacts and emotions related to CWD, inside and outside a CWD management zone. Then we examined coping related to CWD presence, and if the disease affected human health. Most hunters would cope using product shift (i.e., eating meat after a negative test result) rather than displacement (i.e., hunting elsewhere) or dropout. Hunters who may be displaced reported lower involvement in deer hunting, and increased worry about CWD. Results suggest that CWD information and testing may increase hunter worry. Funding expanded testing without prompting displacement or dropout are important management considerations.

Social identity, values, and trust in government: How stakeholder group, ideology, and wildlife value orientations relate to trust in a state agency for wildlife management

Our objective was to understand how social identity and values influenced general public and stakeholder trust in a state wildlife management agency (SWMA). In particular, we wanted to examine how stakeholder group, political ideology, and wildlife value orientation influenced trust in a SWMA. Data were derived from a study of state residents, hunters and livestock producers related to wolf management. Results suggest differences in agency trust correlated with all three factors and the interaction between stakeholder group and wildlife value orientation. Livestock producers reported lower levels of trust in the agency, compared to hunters and the general public. Individuals with conservative or middle-of-the-road ideologies reported less trust in the agency than individuals with a liberal ideology did. Respondents with traditional wildlife values also had less trust in the agency compared to mutualist, pluralist, and distanced respondents. Results suggested similarities in the ideologies and wildlife value orientations of livestock producers and hunters, although these groups differed significantly in their trust in the agency. Agencies face the challenge of managing common-pool, public-trust resources for stakeholders who hold different values and ideologies, and who are differentially affected by management decisions.

Explaining support for mandatory versus voluntary conservation actions among waterfowlers

Personal conservation behavior and compliance with natural resource regulations are important to wildlife conservation. We examined how waterfowl hunting involvement, motivations, satisfaction, and experience, along with institutional trust and demographics, correlated with support for waterfowl regulations and personal conservation actions. Regulations included zones, splits, and motorized decoys, while conservation behaviors addressed hunter recruitment, along with donations, volunteering, and voting in ways to support wildlife conservation. Results suggested that agency trust was positively related to support for regulations but negatively related to personal conservation behaviors. An increased orientation to harvest waterfowl was negatively related to both support for regulations and conservation behaviors. Education, income, Ducks Unlimited membership, and days hunting were positively related to personal conservation behavior. Results may help managers work cooperatively with hunters and conservation groups to support wildlife conservation.

Institutional trust, beliefs, and evaluation of regulations, and management of chronic wasting disease (CWD)

Institutional trust and perceptions of regulatory efficacy can affect support for management. This study examined how institutional trust, specific trust related to information/management, and support for/perceived efficacy of current regulations related to deer hunters’ attitudes about chronic wasting disease (CWD) management. Results are from a survey of southeastern Minnesota deer hunters from the 2018 season, and suggest acceptance of agency management by a majority of hunters. However, a substantial minority of hunters who perceived the management approach was “too aggressive” believed all CWD regulations were ineffective and opposed regulations other than mandatory disease testing and carcass movement restrictions. Results suggest that a lack of shared values, along with greater trust in agency CWD information and technical competence, correlated with perceiving the management approach as “too aggressive.” Future research is needed to understand the contextual nature of trust and how different elements of trust relate to acceptability of management actions.

Recreation conflict, coping, and satisfaction: Minnesota grouse hunters’ conflicts and coping response related to all-terrain vehicle users, hikers, and other hunters

Studying conflict and coping in recreation is important because some coping strategies may provoke distress, while others may lead to positive emotional changes. Building on applications of the transactional stress coping model to park visitors, anglers, and other recreation participants, we explored how Minnesota grouse hunters responded to interference by all-terrain vehicle (ATV)/off-highway vehicle (OHV) users, deer hunters, other grouse/bird hunters, general other hunters, hikers, and bear hunters. We examined relationships among interference, coping, and satisfaction for grouse hunters, and examined how hunter beliefs about ATV use related to perceptions of conflict with ATV users. Encounters with ATV users, deer hunters, other grouse hunters, and hikers lead to problem- and emotion-focused coping, including displacement, confrontive coping, and psychological distancing. Interpersonal conflict with ATVs was positively related to perceptions of interference from ATV users, while no/limited conflict was negatively related. Conflict and coping had a minimal effect on satisfaction. Management implications Although reported levels of interference from other user groups was relatively low, grouse hunters reported moderate interference from ATV users and the use of confrontive coping in response to interactions with ATV riders. Confrontive coping has been associated with increased distress, and deserves attention. However, interference from ATV users was low to moderate and most grouse hunters in the study personally use ATVs for recreation, so there is limited need for management to address conflicts between grouse hunters and ATV riders. Nevertheless, zoning for ATV-free grouse hunting could be tested in areas with reported conflicts between hunters and ATV riders.

Clarifying how hunt-specific experiences affect satisfaction among more avid and less avid waterfowl hunters

Marketing research methods could enhance understanding of hunter satisfaction, a key metric for state wildlife management agencies. We use three marketing research approaches—revised importance-performance, importance-grid, and penalty-reward-contrast analysis—to examine the determinants of waterfowl hunter satisfaction. These methods have seen limited application in research on hunting and other outdoor recreation activities. Using results from a 2015 mail survey, we examine the implicit and explicit motivations and overall satisfaction of Minnesota waterfowl hunters. We also differentiate how experiences relate to satisfaction for more avid and less avid hunters, differentiated by self-reported importance of the activity. Seeing ducks in the field was important to satisfaction for both avidity groups. Bagging ducks each day in the field was more important to satisfaction for less avid hunters, while bagging a lot of ducks over the season and attracting ducks with decoys were more important to the satisfaction of more avid hunters. The methods that we employ here illuminate differences between explicit and implicit motivations for participation in waterfowl hunting, clarify factors crucial to satisfaction, and identify asymmetric influences of experiences on satisfaction and dissatisfaction.

The influence of motivation versus experience on recreation satisfaction: How appreciative- versus achievement-oriented recreation experience preferences relate to hunter satisfaction

We present methods derived from customer satisfaction research that clarify factors influential to the satisfaction of recreation participants. We conducted mail surveys of Minnesota wild turkey hunters to explore differences between the explicit (i.e., stated) and implicit (i.e., derived from the relationship to satisfaction) importance of recreation experience preferences. Revised Importance Performance Analysis, Importance Grid Analysis, and Penalty Reward Contrast Analysis revealed differences between the explicit and implicit importance of recreation experiences, and clarified how activity success may influence the relationship between experiences and satisfaction. We found some support for our hypothesis that experiences related to achievement (of goals for an activity) may more strongly relate to satisfaction than experiences related to appreciation (of nature) or affiliation (with family and friends). Our results emphasized the importance of activity-specific experiences over activity-general experiences for both successful and unsuccessful hunters, and exposed a “motivation matching” process related to harvest success.

How Minnesota wolf hunter and trapper attitudes and risk- and benefit-based beliefs predict wolf management preferences

In 2012, Minnesota’s first-ever regulated wolf hunting and trapping season occurred. Research has suggested that beliefs about risks and benefits associated with carnivores affect their acceptance. Using results from a 2013 mail survey of hunters and trappers who participated in the season, we employed mediation analysis to examine how risk- and benefit-based beliefs influenced the relationship between attitudes about wolves and management preferences and behavioral intentions. Analyses differentiated hunters and trappers. Beliefs about risks and benefits partially explained the relationship between attitudes and wolf management preferences among hunters, while risk-based beliefs fully accounted for management preferences in the trapper sample. Beliefs about risks associated with wolves were most strongly related to management preferences among both hunters and trappers. Beliefs about the risks wolves present to desired game species may be symbolic among hunters and trappers, therefore, managers may be challenged to gain support for recovering wolf populations among these stakeholders.

The influence of angler values, involvement, catch orientation, satisfaction, agency trust, and demographics on support for habitat protection and restoration versus stocking in publicly managed waters

Resource managers benefit from knowledge of angler support for fisheries management strategies. Factors including angler values (protection, utilitarian, and dominance), involvement (attraction, centrality, social, identity affirmation, and expression), catch-related motivations (catching some, many, and big fish, and keeping fish), satisfaction, agency trust, and demographics may relate to fisheries management preferences. Using results from a mail survey of Minnesota resident anglers, we explored how these factors were related to budget support for fish stocking relative to habitat protection/restoration. Results suggest that values, angler involvement, catch orientation, satisfaction, total and recent years fishing, age, and education influence relative support for stocking versus habitat protection/restoration. Utilitarian values, angling centrality, an orientation to catch many fish, satisfaction with the number of fish caught, number of recent years fishing, and age positively related to support for stocking over habitat management, while protection values, attraction to angling, total years fishing, and education level were negatively related to relative support for stocking.

Explicit versus implicit motivations: Clarifying how experiences affect turkey hunter satisfaction using revised importance-performance, importance grid, and penalty-reward-contrast analyses

Although research has advanced methods for clarifying factors that relate to customer satisfaction, they have not been embraced by leisure researchers. Using results from a survey of wild turkey hunters, we applied traditional and revised importance-performance (IPA/RIPA), importance-grid analysis (IGA), and penalty-reward-contrast analysis (PRCA) to examine how activity-specific factors influenced satisfaction. Results suggested differences between the explicit and implicit importance of factors related to turkey hunting. Opportunities to kill turkeys were explicitly rated as less important than seeing, hearing, or calling in turkeys, but opportunities for harvest had relatively higher levels of implicit importance. PRCA identified “calling turkeys in” and “hearing gobbling” as minimum requirements that cause dissatisfaction if not fulfilled, but do not provide satisfaction, whereas “seeing turkeys” and an “opportunity to kill a turkey” related to both satisfaction and dissatisfaction. RIPA, IGA, and PRCA could provide valuable insights about factors that may improve satisfaction for leisure participants.

Discrete choice modeling of season choice for Minnesota turkey hunters

Recreational turkey hunting exemplifies the interdisciplinary nature of modern wildlife management. Turkey populations in Minnesota have reached social or biological carrying capacities in many areas, and changes to turkey hunting regulations have been proposed by stakeholders and wildlife managers. This study employed discrete stated choice modeling to enhance understanding of turkey hunter preferences about regulatory alternatives. We distributed mail surveys to 2,500 resident turkey hunters. Results suggest that, compared to season structure and lotteries, additional permits and level of potential interference from other hunters most influenced hunter preferences for regulatory alternatives. Low hunter interference was preferred to moderate or high interference. A second permit issued only to unsuccessful hunters was preferred to no second permit or permits for all hunters. Results suggest that utility is not strictly defined by harvest or an individual's material gain but can involve preference for other outcomes that on the surface do not materially benefit an individual. Discrete stated choice modeling offers wildlife managers an effective way to assess constituent preferences related to new regulations before implementing them.

How hunter perceptions of wildlife regulations, agency trust, and satisfaction affect attitudes about duck bag limits

This study explored how factors, including the function of bag limits, agency trust, satisfaction, hunting participation, and demographics, related to opinions about duck bag limits. The results are from a survey of 2014 Minnesota resident waterfowl hunters. Analyses identified four dimensions of attitudes about functions of bag limits, including that they: (a) are descriptive in defining the acceptable number of ducks that can be bagged, (b) are injunctive in establishing how many ducks should be allowed to be bagged, (c) ensure fair opportunities for all hunters to bag ducks, and (d) reflect biological limitations to protect waterfowl populations. Descriptive and fairness functions of bag limits were related to opinions about bag limits, as were factors related to agency trust, satisfaction, ducks bagged, experience with more restrictive bag limits, hunter age, and hunting group membership. Agencies may increase support by building trust and emphasizing the descriptive and fairness functions of regulations.

Voice, perceived fairness, agency trust, and acceptance of management decisions among Minnesota anglers

Although researchers agree that public participation in natural resource decision making is critical to institutional acceptance by stakeholders and the general public, the processes to gain public perceptions of fairness, agency trust, and acceptance of management decisions are not clear. Using results from a mail survey of Minnesota resident anglers, we used structural equation modeling to examine how instrumental versus symbolic motives related to anglers’ perceptions of agency fairness, trustworthiness, and ultimately acceptance of fisheries management decisions. We applied laboratory research on relationships among procedural fairness, trust, and management acceptance, and then tested models incorporating anglers’ perceptions of voice for anglers and nonanglers in management decisions. Results suggested that trust fully mediated the relationship between procedural fairness and management acceptance. Angler perceptions of angler and nonangler voice both related to views of procedural fairness, but angler voice was more strongly related and was also significantly related to acceptance of management decisions.

Clarifying beliefs underlying hunter intentions to support a ban on lead shot

Shot from hunting adds toxic lead to environments worldwide. Existing lead shot regulations have been instituted with little understanding of hunter beliefs and attitudes. This study applied the Theory of Reasoned Action, using a multilevel, multivariate approach, to clarify how positive and negative beliefs relate to attitudes about a ban on lead shot. Structure coefficients and commonality analysis were employed to further examine relationships between beliefs and attitudes. Results suggest that while both positive and negative outcomes influence attitudes, positive outcomes were more influential for supporters and negative beliefs for opposers. Management may need to focus on the results from hunters who indicated that they would be unlikely to support a ban, as these hunters include those who may actively oppose additional efforts to regulate lead.
