Abstract

Recreational fishing is practiced by ~ 350 million people globally, and while it historically has been thought to have minimal ecological impact relative to commercial fishing, numerous recreational fisheries have recently declined or collapsed. The potential for recreational fishing to contribute to ecological decline, as well as the incentives of recreational anglers that are distinct from those of commercial fishers, highlights the need for greater understanding of recreational fisheries regulatory options. To aid managers in the decision-making process, we conduct the first comparative review of all seven major approaches to recreational fisheries regulation: harvest size restrictions, harvest quantity restrictions, spatial management, temporal restrictions, accessibility restrictions, rights-based management, and gear restrictions. We provide a synthetic guide for students and practitioners covering how these regulations can benefit target stocks, their potential limitations in achieving sustainability, and angler perceptions of their relative effectiveness and behavioral impositions. Considering the strengths and weaknesses of each strategy, we identify three key fishery metrics that together can guide selection of a suitable combination of regulations that will achieve the requisite biological outcome without restricting angler behavior more than is necessary. With this perspective, we reflect on uncertainties that complicate informed and effective, recreational fisheries regulation.

调节休闲渔业的方法：平衡生物学与垂钓者的满意度

摘要

全球约有 3.5 亿人从事休闲捕鱼，虽然历来认为与商业捕鱼相比，休闲捕鱼对生态的影响最小，但最近许多休闲渔业已经衰退或崩溃。休闲垂钓可能导致生态衰退，以及休闲垂钓者的动机不同于商业垂钓者，突出表明需要更深入地了解休闲渔业监管方案。为了在决策过程中帮助管理者，我们对休闲渔业监管的所有七种主要方法进行了第一次比较审查：捕捞规模限制、捕捞数量限制、空间管理、时间限制、可达性限制、基于权利的管理和渔具限制。我们为学生和从业者提供综合指南，涵盖这些法规如何使目标股票受益、它们在实现可持续性方面的潜在局限性，以及垂钓者对其相对有效性和行为强加的看法。考虑到每种策略的优点和缺点，我们确定了三个关键的渔业指标，它们可以共同指导选择合适的法规组合，以实现必要的生物学结果，而不会过多地限制垂钓者的行为。从这个角度来看，我们反思了使知情和有效的休闲渔业监管复杂化的不确定性。和垂钓者对其相对有效性和行为强加的看法。考虑到每种策略的优点和缺点，我们确定了三个关键的渔业指标，它们可以共同指导选择合适的法规组合，以实现必要的生物学结果，而不会过多地限制垂钓者的行为。从这个角度来看，我们反思了使知情和有效的休闲渔业监管复杂化的不确定性。和垂钓者对其相对有效性和行为强加的看法。考虑到每种策略的优点和缺点，我们确定了三个关键的渔业指标，它们可以共同指导选择合适的法规组合，以实现必要的生物学结果，而不会过多地限制垂钓者的行为。从这个角度来看，我们反思了使知情和有效的休闲渔业监管复杂化的不确定性。
