摘要电捕鱼设备的电输出通常采用恒压或恒安培法进行标准化，然而，简化的电路和电波理论表明，可用于从水向鱼转移的功率(瓦数)的标准化可能是电捕鱼有效标准化的关键。具有标准化功率的电捕鱼确保无论水域条件如何，都可以将恒定的功率转移到鱼身上。标准化功率输出的现场表现鲜为人知。我们使用密西西比河上游跨部门长期资源监测计划(LTRMP)收集的数据来评估电力输出标准化的有效性。这些数据包括278次电捕鱼采集，包括8个物种组的9,282种鱼，于1990年在密西西比河上游4个河段和伊利诺伊河1个河段的主航道边界、死水和尾水水域获得。P.
Abstract The electrical output of electrofishing equipment is commonly standardized by using either constant voltage or constant amperage, However, simplified circuit and wave theories of electricity suggest that standardization of power (wattage) available for transfer from water to fish may be critical for effective standardization of electrofishing. Electrofishing with standardized power ensures that constant power is transferable to fish regardless of water conditions. The in situ performance of standardized power output is poorly known. We used data collected by the interagency Long Term Resource Monitoring Program (LTRMP) in the upper Mississippi River system to assess the effectiveness of standardizing power output. The data consisted of 278 electrofishing collections, comprising 9,282 fishes in eight species groups, obtained during 1990 from main channel border, backwater, and tailwater aquatic areas in four reaches of the upper Mississippi River and one reach of the Illinois River. Variation in p...
