Tips Identifikasi

1. 1

   Mouth structure

   The most distinguishing feature is its large, terminal to superior mouth with a prominent lower jaw that protrudes slightly and fits into a notch in the upper jaw. This is a key adaptation for its predatory, surface-feeding lifestyle.

2. 2

   Body shape

   Its torpedo-like, elongated body is unique among most large European cyprinids, which tend to be deeper-bodied.

3. 3

   Absence of barbels

   Unlike many other cyprinids (e.g., barbel, carp), the Asp lacks barbels around its mouth.

4. 4

   Scale size

   Has relatively small, embedded scales compared to other large cyprinids, giving it a smoother appearance.
