WebJun 27, 2024 · To determine the upper lethal limit of larval Arctic lamprey, we used the incipient lethal temperature (ILT) and the acclimated chronic exposure (ACE) methods. The ILT method involves transferring test fish rapidly from an acclimation temperature to a constant test temperature and measuring tolerance in terms of time to death (Brett 1952 ).
