Performance measures are an important tool to assess the impact of environmental change on animals. In fish, performance is often measured as critical swimming speed (Ucrit), which reflects individual maximal physiological capacities. A drawback Ucrit that trials relatively long (∼30-75 min). may therefore not be suitable for several repeated measurements because potential training effects, recovery periods, and low throughput. Here we test a shorter (∼4-5 min) protocol, "Ucrit fast" (UCfast) in zebrafish (Danio rerio). We show UCfast have similar, significant repeatabilities within individuals. Unlike Ucrit, did elicit effect. Both provide same insights into thermal acclimation, both similar estimates acclimation capacity doubly acclimated fish. propose valid substitute particularly when higher throughput necessary.
