Pallid sturgeon

Just like other species of sturgeon, their populations were significantly overharvested by the commercial fishery in the 1900’s for their eggs or caviar. The pallid sturgeon was listed as Endangered under the Endangered Species Act in 1990 because of habitat degradation, declines in water quality throughout their range and the building of dams that impaired the pallid sturgeon’s ability to migrate to their natural spawning grounds.
