Evaluating How Changing Climate and Water Clarity Can Affect Restoration of Native Coregonine Fish in Midwestern Lakes
Coregonines are a sub-family of freshwater fishes within the well-known Salmonidae family. In the upper midwestern U.S., these fishes have provided a key food source to Native Americans for millennia and immigrants for the last several centuries. Since the mid-20th century, however, their diversity and abundance has declined owing to several anthropogenic stressors including overfishing, declining
Quantifying the Impacts of Climate Change on Fish Growth and Production to Enable Sustainable Management of Diverse Inland Fisheries
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 f
Forecasting Climate Change Induced Effects on Recreational and Commercial Fish Populations in the Great Lakes
Great Lakes fishery managers and stakeholders have little information regarding how climate change could affect the management and conservation of fish populations, including those of high recreational and commercial value. Scientists from the US Geological Survey (USGS) worked closely with state management agencies and the National Wildlife Federation to complete several objectives that provide k
