Using aerobic exercise to evaluate sub-lethal tolerance of acute warming in fishes

David McKenzie
We investigated whether fatigue from sustained aerobic swimming provides a sublethal endpoint to define tolerance of acute warming in fishes, as an alternative to loss of equilibrium (LOE) during a critical thermal maximum protocol (CTmax). Two species were studied, Nile tilapia Oreochromis niloticus and pacu Piaractus mesopotamicus. Each fish underwent an incremental swim test to determine gait transition speed (UGT), where it first engaged the unsteady anaerobic swimming mode that preceded fatigue. After suitable recovery...
