麝香(E.masquongy)幼虫的临界热极大值(CTM)和粉虱(E.masquongy)雌虫的临界热值(CTM)E.Lucius雄性)在孵化条件下测定。诺朗日具有较高的耐温性，发育较快。幼虫的CTM(30.9-36.0度)C，平均34.0度。C)显著高于麝香(29.9-35.6度)。C，平均32.8度。c)。这两种鱼的CTM值在上游都急剧下降，然后是一个缓慢的恢复期，特征是CTM值普遍上升。年龄和过去的热史对鱼苗的耐温性都有重要影响。诺氏鱼苗比麝香鱼苗更能适应不断变化的环境条件。
Critical thermal maxima (CTM) of larval muskellunge (E. masquinongy) and norlunge (E. masquinongy females .times. E. lucius males) were determined under hatchery conditions. Norlunge had higher temperature tolerance and developed faster. CTM of larval norlunge (30.9-36.0.degree. C, mean, 34.0.degree. C) were significantly higher than those of muskellunge (29.9-35.6.degree. C, mean, 32.8.degree. C). Both fish exhibited a sharp decrease in CTM during swim-up, followed by a slow recovery period characterized by a general increase in CTM values. Both age and past thermal history had important effects on temperature tolerance of fry. Norlunge fry were better able to physiologically adjust to changing environmental conditions than muskellunge.
