Article Synopsis
- Winter climate changes are impacting salmonid thermal biology, specifically affecting the hatching success and performance of fall-spawning brook trout due to stressors during winter egg incubation.
- The study examined the effects of different thermal regimes on brook trout embryos, fry, and adults, highlighting that warmer incubations increased thermal tolerance in embryos but not in later life stages.
- Results indicated that brook trout experience short-term carryover effects from thermal stress during embryonic stages, with minimal long-term impacts as they matured.
Critical thermal maximum (CT) is widely used for measuring thermal tolerance but the strong effect of acclimation on CT is a likely source of variation within and among studies/species that makes comparisons more difficult. There have been surprisingly few studies focused on quantifying how quickly acclimation occurs or that combine temperature and duration effects. We studied the effects of absolute temperature difference and duration of acclimation on CT of brook trout (Salvelinus fontinalis), a well-studied species in the thermal biology literature, under laboratory conditions to determine how each of the two factors and their combined effects influence critical thermal maximum.
