America’s native fish species are facing a conservation crisis. Nearly 40% of North American fishes, 700 species, are facing an imminent threat of becoming endangered. More than two-thirds of our native fish species are listed as threatened or endangered under the Endangered Species Act. Fish hatcheries provide a way of introducing healthy reproducing adults back into their natural environments. This effort to boost population allows the native species to reclaim habitats lost to invasive species or pollution. Fish hatcheries partner with U.S. Fish and Wildlife to monitor the ecosystems these species reside in. These partnerships with government agencies and environmental groups allows for conservation efforts to be protected.
