Consigli per l'identificazione

1. 1

   Mouth Position

   The Triotto has a distinctly upward-pointing (superior) mouth, adapted for feeding at the surface or on submerged vegetation. This differentiates it from the Roach (Rutilus rutilus) which has a terminal mouth.

2. 2

   Fin Coloration

   The bright red to orange coloration of the pectoral, pelvic, anal, and caudal fins is a primary identifier. The dorsal fin is usually greyish-brown.

3. 3

   Dorsal Fin Origin

   The origin of the dorsal fin is typically behind the origin of the pelvic fins. In contrast, the Roach's dorsal fin origin is usually directly above or slightly in front of the pelvic fin origin.

4. 4

   Body Shape

   Possesses a deeper, more compressed body compared to the more slender Roach.

5. 5

   Eye Color

   The iris of the eye often has a reddish-orange tint, which can be a helpful, though not always definitive, characteristic.
