项目摘要
Water temperature interacts with coldwater trout populations in a number of ways. For example, trout that are captured in recreational fisheries during warm summer temperatures or in the winter during ice fishing may experience elevated post-release mortality. In the case of managed waterbodies, suitable summer thermal habitat may become limiting for trout. Stocking decisions that do not adequately consider temperature can lead to mortality such that resources are wasted and fisheries supplementation targets are not met. From a biodiversity perspective, trout can be obligate hosts for imperiled freshwater mussels to complete their life cycle such that if thermal conditions exclude trout, mollusc populations may be extirpated. All of these issues are salient to Kenauk Properties LP which is a tourism outfitter that owns and operates the largest private nature reserve in Canada. They have concerns about how to better manage rainbow and brook trout populations (e.g., which fish to stock, where to invest in habitat restoration, how to optimize hatchery operations). We will conduct a multi-year study to consider the relevance of the thermal biology of trout to the management of fisheries resources at Kenauk. Objectives include 1). Characterize the thermal biology and oxygen conditions of ten fishing lakes within Kenauk reserve; 2). Determine how stocked trout use lakes of different thermal conditions with a particular focus on thermal habitat and depth selection. 3). Determine how exogenous stressors (such as fishing) influence thermal selection, physiological state, and survival of stocked trout. 4). Identify biomarkers that influence thermal selection and survival of stocked fish. 5). Characterize the seasonal habitat selection, movement and thermal biology of wild trout in the Kinonge River. The project ideas were developed using a co-production model that will extend throughout the project to ensure relevance of research to Kenauk. Collectively this research will generate new knowledge that will help Kenauk to better manage their stocked recreational fisheries resources in the face of climate change so they can continue to provide exceptional angling opportunities for their clients and also conserve remaining wild fish populations.
水温以多种方式与冷水鳟鱼种群相互作用。 例如,在温暖的夏季温度或冬季冰钓期间在休闲渔业中捕获的鳟鱼可能会经历释放后死亡率升高。 在受管理的水体的情况下,合适的夏季热栖息地可能成为限制鳟鱼。 没有充分考虑温度的放养决定可能导致死亡,从而浪费资源,无法实现渔业补充目标。从生物多样性的角度来看,鳟鱼可以专性主机的濒危淡水贻贝完成其生命周期,如果热条件排除鳟鱼,软体动物种群可能会灭绝。 所有这些问题对Kenauk Properties LP来说都很突出,Kenauk Properties LP是一家拥有并经营加拿大最大的私人自然保护区的旅游装备商。 他们担心如何更好地管理虹鳟和溪鳟的种群(例如,哪种鱼应该放养,在哪里投资于栖息地恢复,如何优化孵化场的运作)。 我们将进行一项多年期研究,以考虑鳟鱼的热生物学与Kenauk渔业资源管理的相关性。 目标包括1)。描述Kenauk保护区内十个渔业湖泊的热生物学和氧气条件; 2)。确定如何放养鳟鱼使用不同的热条件的湖泊,特别侧重于热栖息地和深度选择。 (3)第三章。确定外源压力(如捕鱼)如何影响热选择,生理状态,和库存鳟鱼的生存。 4).识别影响热选择和放养鱼类生存的生物标志物。 5)。描述季节性栖息地的选择,运动和热生物学的野生鳟鱼在基农格河。 该项目的想法是使用合作生产模式,将扩展到整个项目,以确保研究的相关性,以Kenauk开发。 总的来说,这项研究将产生新的知识,这将有助于Kenauk在气候变化的情况下更好地管理其库存的休闲渔业资源,以便他们能够继续为客户提供特殊的钓鱼机会,并保护剩余的野生鱼类种群。
