Stream fish are in peril from a changing climate, particularly for species with restricted distributions or populations on the southern edge of their range. For these fish, the opportunity to escape warming temperatures is limited by the network of stream channels accessible to them. To deal with temperatures beyond their physical capacity, fishes must move, adapt, or die. However, little is known for many of these species about their preferred temperatures, critical temperature limits, or capacity to adapt to or tolerate increasing temperatures. Researchers will measure the preferred temperatures and tolerance of two stream fish that are vulnerable to climate change: the Ozark Shiner and the Blacknose Shiner. The...

Stocking, or raising fish in hatcheries and releasing them into a body of water, is routinely used to supplement or maintain fisheries when natural populations are low or nonexistent. Demand for stocking cool and coldwater fish species that support important fisheries will likely increase as a result of climate change, but fish available for stocking are a limited resource. Consequently, climate change will likely affect supply-and-demand tradeoffs associated with stocking fish in the future, where demand for fish is likely to exceed supply. Researchers will examine supply-and-demand tradeoffs using walleye, which represent an ideal species for this assessment because they are a native coolwater species supporting...
