We assessed thermal and salinity limits in several ontogenetic stages and acclimation states of Delta Smelt to evaluate sensitivity to climate change stressors. Thermal tolerance decreased among successive stages, and juvenile tolerance limits were closest to current environmental conditions. Salinity impacted juvenile and adult survival in exposures over acute timescales.
