Nile Tilapia
Nile Tilapia (Oreochromis niloticus) are an invasive African cichlid species with a limited and questionable presence in Arizona.
These fish were reportedly introduced experimentally to fish farms in southern Arizona in the 1960s-70s, but their identification has been disputed by researchers, with some suggesting early reports may have been misidentified as other tilapia species like Tilapia mariae.
Scientific Name: Oreochromis niloticus
- Nile Tilapia are distinguished from the more common Blue Tilapia by having 16-18 dorsal spines (versus 15-16), 29-31 total dorsal fin rays, and distinctive dark vertical stripes on their tail fins.
- They can reach up to 60cm in length and 4.3kg, living up to 9 years.
