Juvenile Pacific Lamprey and American eels were used for laboratory evaluations to determine potential effects from tag implantation. Telemetry technology has been identified as a way to obtain more detailed information on movement and behavior across a broader spatial scale than is possible with other known technology. The purpose of this method is to provide a detailed step by step instruction on tag implantation for both lampreys and eel. For laboratory studies using actively migrating juvenile Pacific Lamprey (120-160 mm), we determined that the presence of the tag did not alter the swimming ability between tagged and untagged Individuals or have any significant tag loss (<3%). Similar results were determined during laboratory testing of Yellow phase American Eels (113-175 mm). No mortality occurred during a 38-day holding period and there was minimal tag loss (3.8%). The presence of the tag did not have any significant effect on the swimming ability or survival of tagged eels compared to untagged controls and there was minimal tag loss.
幼年太平洋七鳃鳗和美洲鳗鱼被用于实验室评估，以确定标记植入的潜在影响。遥测技术已被视为一种比其他已知技术更能在更广泛空间尺度上获取有关运动和行为的详细信息的方法。该方法的目的是为七鳃鳗和鳗鱼的标记植入提供详细的分步指导。对于使用积极洄游的幼年太平洋七鳃鳗（120 - 160毫米）进行的实验室研究，我们确定标记的存在不会改变标记个体和未标记个体之间的游泳能力，也不会导致任何显著的标记丢失（<3%）。在黄化阶段美洲鳗鱼（113 - 175毫米）的实验室测试中也得到了类似结果。在38天的饲养期内没有死亡发生，标记丢失极少（3.8%）。与未标记的对照相比，标记的存在对标记鳗鱼的游泳能力或生存没有任何显著影响，且标记丢失极少。
