Fisheries managers in Midwestern lakes and reservoirs are tasked with balancing multiple management objectives to help maintain healthy fish populations across a landscape of diverse lakes. As part of this, managers monitor fish growth and survival. Growth rates in particular are indicators of population health, and directly influence the effectiveness of regulations designed to protect spawning fish or to promote trophy fishing opportunities. Growth, combined with reproduction and survival, also determines the amount of fish biomass available for harvest, known as population production. Changing water temperatures can influence growth and production of managed fish species in multiple complex ways, increasing 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...
