Several large Irish lake fisheries comprise both pike (Esox Lucius) and brown trout (Salmo trutta). Due to predation on trout, pike stocks are actively managed in several locations with the objective of enhancing the trout fishery, which is a policy strongly supported by some trout anglers but intensely opposed by pike anglers. In the context of scientific support for management decisions concerning these mixed resource fisheries there is a dearth of economics knowledge. This paper addresses some of that knowledge gap, investigating factors affecting angling recreational demand within these mixed resource fisheries and whether there are significant differences between pike and brown trout anglers. We estimate a travel cost model and test whether pike and trout anglers have different demand preferences. The most substantive policy-relevant finding from the research relates not to differences associated with target species but to angling club membership. Angling club members are more price inelastic in their demand and particularly so in the case of trout anglers. *Corresponding author: gianluca.grilli@esri.ie Acknowledgements: Funding from Inland Fisheries Ireland is gratefully acknowledged. a.

混合资源渔业中的休闲垂钓需求

爱尔兰的几个大型湖泊渔业包括梭鱼（Esox Lucius）和褐鳟鱼（Salmo trutta）。由于捕食鳟鱼，在多个地点积极管理梭鱼种群，以提高鳟鱼捕捞量，这是一些鳟鱼垂钓者强烈支持但梭鱼垂钓者强烈反对的政策。在对有关这些混合资源渔业的管理决策的科学支持方面，缺乏经济学知识。本文解决了一些知识差距，调查了影响这些混合资源渔业中垂钓休闲需求的因素，以及梭子鱼和褐鳟鱼垂钓者之间是否存在显着差异。我们估计一个旅行成本模型并测试派克和鳟鱼垂钓者是否有不同的需求偏好。研究中最实质性的政策相关发现与目标物种相关的差异无关，而是与钓鱼俱乐部会员资格有关。垂钓俱乐部会员的需求价格缺乏弹性，尤其是鳟鱼垂钓者。*通讯作者：gianluca.griilli@esri.ie 致谢：感谢爱尔兰内陆渔业的资助。一种。经济和社会研究所，都柏林 b. 都柏林三一学院 C. 社会经济海洋研究组，惠特克研究所，爱尔兰国立大学，戈尔韦 ESRI 工作论文代表了研究人员正在进行的未经审查的工作，研究人员对其中的内容和表达的任何观点负全部责任。欢迎对这些论文提出任何意见，并应通过电子邮件发送给作者。论文只能下载供个人使用。
