Etymology: Carasobarbus: Latinization of , karass, karausche, European crucian carp + Latin, barbus = barbel (Ref. 45335);  exulatus: The specific name is derived from the Latin for banished and refers to the isolation of its habitats (Ref. 113720).

背棘 (總數) : 0; 背的軟條 (總數) : 11 - 14; 臀棘: 0; 臀鰭軟條: 8 - 9; 脊椎骨: 37 - 39. Diagnosis: The mouth of this species has a more ventral position than that of the other Carasobarbus species, being almost inferior (Ref. 57642). It is the only species of the genus Carasobarbus in which both pairs of barbels are always present, the barbels of the anterior pair being often very short, but not quite rudimentary (Ref. 57642). Carasobarbus exulatus differs from all congeners, except C. fritschii and C. harterti in modally having 9 instead of 10 branched dorsal-fin rays; it differs from C. fritschii and C. harterti in modally having 12 scales around the least circumference of the caudal peduncle vs. 16 and in having 24-32 scales on the lateral line vs. 30-39 and 31-38 respectively (Ref. 94477).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.0   ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  中等的, 族群倍增時間最少 1.4 - 4.4年 (Assuming Fec < 10,000).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (25 of 100).
