How to Identify Pangusia Labeo

To identify Pangusia Labeo (Labeo pangusia), look at these key features.

Physical Characteristics

Body shape

elongated

Coloration

Dorsal side is typically dark grey to olive-brown, fading to silvery-white on the ventral side. Fins are often dusky.

Scale type

cycloid

Mouth position

subterminal

Distinctive features

Elongated, cylindrical body, Subterminal mouth with thick, fleshy lips, Two pairs of barbels (rostral and maxillary), Absence of a horny covering on the inner surface of the lips, Lateral line complete, with 40-43 scales

Dorsal fin

Single dorsal fin with 12-14 branched rays, originating slightly anterior to the pelvic fins.

Tail fin

Deeply forked caudal fin.

Pectoral fin

Pectoral fins are relatively short, not reaching the pelvic fins.

Distinctive fins

Anal fin with 5 branched rays. Pelvic fins with 8 branched rays.

Identification Tips

1. 1

   Mouth and Barbels

   Look for the subterminal mouth with thick, fleshy lips and two distinct pairs of barbels (rostral and maxillary). This distinguishes it from some other Labeo species that may have fewer or no barbels.

2. 2

   Body Shape and Coloration

   Its elongated, somewhat cylindrical body and dark dorsal, silvery ventral coloration are characteristic. The absence of prominent spots or bands helps differentiate it from other Labeo species.

3. 3

   Fin Ray Counts

   Counting the branched rays in the dorsal fin (12-14) and anal fin (5) can be a definitive identification feature for ichthyologists.
