The blue catfish, or Ictalurus is Greek meaning “fish cat”, and furcatus is Latin, meaning “forked”, a reference to the species’ forked tail fin. Blue catfish have a forked tail, and are sometimes very similar to channel catfish. However, only the Rio Grande population has dark spots on the back and sides. The number of rays in the anal fin is typically 30-35, and coloration is usually slate blue on the back, shading to white on the belly. Blue cats typically range from 20 to 40 pounds in size.
