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鲑鱼种群相互作用。例如,在夏季温暖或冬季冰钓期间在休闲渔业捕获的鲑鱼可能会经历更高的放生后死亡率。对于受管理的水体,适宜的夏季热栖息地可能会限制鲑鱼的生存。没有充分考虑温度的放养决定可能会导致死亡,从而浪费资源,达不到渔业补充目标。从生物多样性的角度来看,鲑鱼可以成为濒危淡水贻贝的专属宿主,以完成它们的生命周期,因此,如果高温条件不包括鲑鱼,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,该公司是一家旅游用品公司,拥有并运营着加拿大最大的私人自然保护区。他们关心的是如何更好地管理虹鲑鱼和溪鲑鱼的种群(例如,要饲养哪些鱼,在哪里投资恢复栖息地,如何优化孵化场的运营)。我们将进行一项为期多年的研究,以考虑鲑鱼的热生物学与基诺克渔业资源管理的相关性。目标包括1)。描述科诺克保护区内10个渔湖的热生物学和氧气条件;2)。确定放养的鲑鱼如何利用不同温度条件的湖泊,特别关注温度、栖息地和深度选择。3)。确定外源应激源(如捕鱼)如何影响放养鲑鱼的温度选择、生理状态和生存。4)。确定影响放养鱼类的温度选择和存活率的生物标志物。5)。描述基隆日河野生鲑鱼的季节性栖息地选择、运动和热生物学。该项目的想法是利用联合制作模式制定的,该模式将延伸到整个项目,以确保研究与科诺克的相关性。总体而言,这项研究将产生新的知识,帮助Kenauk在面对气候变化时更好地管理其所放养的休闲渔业资源,以便继续为客户提供特殊的垂钓机会,并保护剩余的野生鱼类种群。
