Scientists confirm two new black bass species in Georgia rivers, distinct from redeye bass, based on DNA and physical traits.

Researchers from the University of Georgia and partner institutions have identified two new black bass species—Bartram's bass and Altamaha bass—previously mistaken for redeye bass. Though sightings date back to the 1980s, detailed physical and genetic analysis confirmed their distinct status. Using mitochondrial DNA and nuclear genome comparisons, the team ruled out hybridization and documented unique traits. Both species inhabit river pools and rocky shoals, surviving in altered habitats. The study, published in Zootaxa, was supported by state wildlife grants and marks a significant update to North American fish taxonomy.
