To identify Common Carp (Cephalus carpio), look at these key features.

Physical Characteristics

Body shape

compressed

Wild carp typically have a brassy or olive-green back, fading to yellowish-gold on the flanks and a whitish belly. Ornamental varieties (Koi) exhibit a vast array of colors including white, black, red, orange, yellow, and blue, often in intricate patterns.

Scale type

cycloid

Mouth position

subterminal

Distinctive features

Two pairs of barbels on the upper jaw (one short, one long), Large, thick scales (except for mirror and leather carp varieties), Deep, robust body, Long dorsal fin with a serrated spine

Dorsal fin

Long, with 3-4 hard, serrated spines and 17-22 soft rays. The third spine is typically the longest and strongest.

Tail fin

Deeply forked, with rounded lobes.

Pectoral fin

Relatively short and rounded, located low on the body.

Distinctive fins

Pelvic fins are abdominal, located behind the pectoral fins. Anal fin is short with 3-5 soft rays and 2-3 spines, one of which is serrated.

Identification Tips

1. 1

   Barbels

   Presence of two pairs of barbels on the upper jaw is a key distinguishing feature from many other freshwater fish.

2. 2

   Dorsal Fin

   The long dorsal fin with a strong, serrated spine is characteristic.

3. 3

   Scales

   Wild carp have large, regular scales. Mirror carp have very large, irregularly placed scales, and leather carp are largely scaleless. This helps differentiate varieties.

4. 4

   Body Shape

   The deep, robust, and laterally compressed body is typical.
