Abstract

Abstract Stakeholders with shared interests in fish conservation often disagree about which specific conservation measures are appropriate, leading to conflicts with sometimes long‐lasting and disruptive social and political effects. Managers are challenged to balance opposing stakeholder preferences with their own mandates in a charged environment. Using the 2014 termination of Atlantic salmon (Salmo salar) stocking in Wales as a case, we conducted a critical discourse analysis of interview data, online print media, social media and policy documents to examine conflict and its mechanisms over time. The data sources represented four discourse planes: the social, media, social media and policy planes. We report five key findings: The conflict around salmon stocking took place in three stages, beginning with a negotiated, manifest conflict that escalated during the 2014 policy process that terminated stocking, creating a persistent spin‐off conflict. The stocking debate was shaped by two discourse coalitions promoting either pro‐ or anti‐hatchery arguments, and an emerging third coalition advocating for compromise. The coalitions disagreed on the effectiveness of stocking, the status of the salmon stock and had different management goals, revealing that the pro‐ or anti‐stocking debate was caused by complex, intertwined and partly opposing beliefs and values. Different elements of the discourses emerged on different planes and arguments were mobile across the planes over time, explaining how selected key arguments were able to persist, gain dominance, re‐appear over time, thus dynamically fuelling and (re)shaping the conflict. The policy change decision to terminate stocking in Wales institutionalized anti‐stocking discourses. It forced all stakeholder groups to acquiesce to one perspective of stocking, creating a win‐lose situation for some stakeholders. The handling and result of the policy change led to the alienation of some stakeholder groups. Ecological management goals were achieved in the short term, but the acrimonious and yet‐unsettled social side effects affected the long‐term relationships and may negatively impact future conservation issues in the area. We conclude that transdisciplinary active management designed for joint learning about stocking trade‐offs may be a suitable alternative to the ‘either‐or' outcomes observed in Wales that fostered sustained stakeholder conflicts instead of joint production of knowledge and understanding.

Highlights

  • Fish stocking has historically been a popular management measure, with the intention of enhancing fishing opportunities, compensat‐ ing for degraded environments, replacing missing or dysfunctional spawning sites, and supporting threatened or declining populations (Arlinghaus, Tillner, & Bork, 2015; Berg, 1986; Cowx, 1994; Hilborn & Eggers, 2000; Lorenzen et al, 2013)

  • NRW’s summary and analysis of the consultation responses (Natural Resources Wales, 2014b) stated that ‘there has been no new evidence brought to our attention that might amend the conclu‐ sions set out in our initial review’ (NRM & Salmon Stocking Report, p. 3), though our analysis found that many consultation responses from the Decline Coalition cited a number of authors, policies, and stud‐ ies that they believed to support their case

  • We analysed the stocking debate in the River Wye in Wales to understand conflict as it emerged over time and across different discourse planes

Summary

| INTRODUCTION

Fish stocking has historically been a popular management measure, with the intention of enhancing fishing opportunities, compensat‐ ing for degraded environments, replacing missing or dysfunctional spawning sites, and supporting threatened or declining populations (Arlinghaus, Tillner, & Bork, 2015; Berg, 1986; Cowx, 1994; Hilborn & Eggers, 2000; Lorenzen et al, 2013). The main concern is that hatchery fish, when released in large numbers into threatened wild populations, can outcompete or outnumber their wild conspecifics (Blanchet, Páez, Bernatchez, & Dodson, 2008; Jonsson & Jonsson, 2006; Swain & Riddell, 1990) and through cross‐breeding affect the genetic integrity of wild subpopu‐ lations through a process called genetic swamping (Garcia de Leaniz et al, 2007; Laikre, Schwartz, Waples, & Ryman, 2010). In 2015, the last remaining SNR pond‐reared salmon were released into the Wye
