<div><font face="Arial">The sustainability of freshwater fisheries is
increasingly affected by climate warming, habitat alteration, invasive
species and other drivers of global change. The State of Michigan,
USA, contains ecologically, socioeconomically valuable coldwater
stream salmonid fisheries that are highly susceptible to these
ecological alterations. Thus, there is a need for future management
approaches that promote resilient stream ecosystems that absorb change
amidst disturbances. Fisheries professionals in Michigan are
responding to this need by designing a comprehensive management plan
for stream brook charr (<i>Salvelinus fontinalis</i>), brown trout
(<i>Salmo trutta</i>) and rainbow trout (<i>Oncorhynchus mykiss</i>)
populations. To assist in developing such a plan, we used
stream-specific regression models to forecast thermal habitat
suitability in streams throughout Michigan from 2006 to 2056 under
different predicted climate change scenarios. As baseflow index (i.e.,
relative groundwater input) increased, stream thermal sensitivity
(i.e., relative susceptibility to temperature change) decreased. Thus,
the magnitude of temperature warming and frequency of thermal habitat
degradation were lowest in streams with the highest baseflow indices.
Thermal habitats were most suitable in rainbow trout streams as this
species has a wider temperature range for growth
(12.0-22.5 °C) compared to brook charr (11.0-20.5 °C)
and brown trout (12.0-20.0 °C). Our study promotes
resilience-based salmonid management by providing a methodology for
stream temperature and thermal habitat suitability prediction.
Fisheries professionals can use this approach to protect coldwater
habitats and drivers of stream cooling and ultimately conserve
resilient salmonid populations amidst global change.</font><br>
