Age‐0 Walleye Sander vitreus are stocked to achieve several management objectives. However, stocked Walleye are exposed to numerous handling‐ and transport‐related stressors that can negatively influence disease resistance, survival, year‐class strength, and fisheries management objectives. The objective of this study was to evaluate relationships between Walleye transport duration with changes in water chemistry, whole‐blood glucose and plasma cortisol concentrations, and short‐term (48‐h) mortality. Walleye were transported between 3.5 and 6.0 h and stocked into holding cages located at one of seven sites. Water quality and stress (via whole‐blood glucose and plasma cortisol) and mortality were evaluated prior to, during, and at 0, 2, 24, and 48 h posttransportation. During transport, water temperatures generally decreased, while carbon dioxide concentrations fluctuated between 2.7 and 22.5 mg/L. Walleye whole‐blood glucose and plasma cortisol concentrations varied by site and time since transport. Changes in carbon dioxide concentrations were associated with changes in whole‐blood glucose concentrations. However, cumulative survival rates and plasma cortisol concentrations were not associated with water quality or transportation duration. Understanding Walleye tolerance to transportation‐induced stress has the potential to enhance stocking programs by providing the opportunity for managers to make informed transport decisions.

运输时间和水质对0岁0岁角膜白斑应力和生存的影响

年龄0的Walleye Sander玻璃体可以实现几个管理目标。但是，库存的角膜白斑暴露于许多与处理和运输相关的压力源下，可能会对疾病抵抗力，生存，年强度和渔业管理目标产生负面影响。这项研究的目的是评估角膜白斑运输时间与水化学变化，全血葡萄糖和血浆皮质醇浓度以及短期（48小时）死亡率之间的关系。角膜白斑在3.5至6.0小时之间运输，并放到位于七个地点之一的饲养笼中。在运输前，运输后，运输后，运输后，运输24小时和48小时，评估水质和压力（通过全血葡萄糖和血浆皮质醇）和死亡率。在运输过程中，水温通常会下降，而二氧化碳浓度在2.7至22.5 mg / L之间波动。自运输以来，角膜全血葡萄糖和血浆皮质醇浓度随部位和时间而变化。二氧化碳浓度的变化与全血葡萄糖浓度的变化有关。但是，累积存活率和血浆皮质醇浓度与水质或运输时间无关。通过为经理提供知情的运输决策机会，了解角膜猴对运输引起的压力的承受能力有可能增强库存计划。但是，累积存活率和血浆皮质醇浓度与水质或运输时间无关。通过为经理提供知情的运输决策机会，了解角膜猴对运输引起的压力的承受能力有可能增强库存计划。但是，累积存活率和血浆皮质醇浓度与水质或运输时间无关。通过为经理提供知情的运输决策机会，了解角膜猴对运输引起的压力的承受能力有可能增强库存计划。
