Continued management interest in using White Sucker Catostomus commersonii population manipulations to improve the growth of Northern Pike Esox lucius and potentially competing panfish species provided an opportunity to evaluate White Sucker removal and supplementation in Michigan lakes. Overabundant White Suckers from one lake were transferred into two lakes where higher populations were desired, with fish growth responses being evaluated in each lake and in a control lake pretransfer and at 5 years posttransfer. Criteria for project success were (1) continued low abundance of White Suckers in the removal lake and increased abundance in the recipient lakes; (2) positive growth response of panfish species to White Sucker removals; and (3) positive growth response of Northern Pike to White Sucker additions. After 5 years, White Sucker population abundance and recruitment patterns showed continued survival of stocked adults but little recruitment in stocked lakes and the fish species examined showed no clear positive growth responses to White Sucker manipulations. Fishery managers should carefully consider the costs and benefits of using White Sucker manipulations as a management tool.

北方湖泊去除白头S和放养对鱼类生长的影响

使用白色吸盘继续管理利益Catostomus commersonii人口操作，以提高白斑狗鱼的生长白斑狗鱼潜在的竞争性泛鱼物种为评估密歇根湖中白吸盘的去除和补充提供了机会。来自一个湖泊的过多白吸盘被转移到两个需要较高种群的湖泊中，并在转移前和转移后5年评估了每个湖和对照湖中鱼的生长反应。项目成功的标准是（1）清除湖中白吸盘的持续低含量和接受者湖中的高丰度；（2）盘鱼物种对白吸盘去除的积极生长反应；（3）Northern Pike对White Sucker添加物的积极生长反应。5年后 White Sucker种群的丰度和募集模式表明，有种群的成年成年人得以继续生存，但在有种群的湖泊中几乎没有募集，所检查的鱼种对Wh​​ite Sucker的操纵没有明显的积极增长反应。渔业管理人员应仔细考虑使用White Sucker操纵作为管理工具的成本和收益。
