Bestimmungstipps

1. 1

   Coloration and Pattern

   The most obvious identifier. Koi exhibit a vast array of distinct color patterns (e.g., Kohaku, Sanke, Showa, Utsuri, Asagi, Shusui, Ogon). Common carp are typically uniformly olive-green to brownish-gold.

2. 2

   Barbels

   Both Koi and common carp have two pairs of barbels. However, in Koi, these are often less prominent or can be obscured by breeding for specific head shapes.

3. 3

   Body Shape

   While both are robust, Koi are often bred for a more streamlined, torpedo-like body shape, especially show-quality specimens. Common carp can appear more stout.

4. 4

   Scalation

   Most Koi have large, cycloid scales. However, 'Doitsu' varieties have reduced or absent scales, which is a clear distinguishing feature from fully scaled common carp.
