Inland fishes are important to communities worldwide and provide many ecosystem services, such as recreational opportunities, subsistence fishing, and commercial income. However, freshwater fishes are especially vulnerable to climate change. To support climate adaptation for fisheries management across the globe, the USGS Alaska, Missouri, and North Carolina Cooperative Research Units recently partnered with the USGS National Climate Adaptation Science Center (CASC), the University at Buffalo, George Mason University, and the Ontario Ministry of Natural Resources and Forestry to develop an interactive database, FiCli (pronounced “fick-lee”).
