由于气候变化和景观规模的栖息地干扰等许多驱动因素，湖泊生态系统正在发生变化，削弱了它们支持一些渔业的潜力。在一些湖泊中，支持北美各地娱乐和部落渔业的WalleyeSander vitreus(Mitchill)种群已经下降。气候变化、收获、入侵物种和暖水鱼(如森鱼科)的同时增加可能是造成下降的原因之一。为了测试集约化管理行动的有效性，在监测鱼类群落反应的同时，在4年多的时间里，从一个33公顷的湖泊中实验性地移走了约28.5万只中心虫。着丝虫丰度下降，黄姑鱼增加，但没有观察到大眼鱼补充的证据。这些发现探索了密集抵抗作为一种支持大眼病面临环境变化的管理策略的可行性，并为管理层提供了一个平台，以超越抵抗-接受-直接(RAD)框架中的抵抗策略，以驾驭生态系统变化。
Lake ecosystems are shifting due to many drivers including climate change and landscape‐scale habitat disturbance, diminishing their potential to support some fisheries. WalleyeSander vitreus(Mitchill) populations, which support recreational and tribal fisheries across North America, have declined in some lakes. Climate change, harvest, invasive species and concurrent increases in warm‐water fishes (e.g. Centrarchidae) may have contributed to declines. To test the utility of an intensive management action to resist walleye loss, an experimental removal of ~285,000 centrarchids from a 33‐ha lake over 4 years was conducted while monitoring the fish community response. Centrarchid abundance declined and yellow perchPerca flavescens(Mitchill) increased, yet no evidence of walleye recruitment was observed. These findings explore the feasibility of intensive resistance as a management strategy in supporting walleye facing environmental change and provide a platform for management discussions to move beyond resist strategies in the Resist‐Accept‐Direct (RAD) framework to navigate ecosystem change.
