Short description Morfologi | Morfometri

A small-sized, deep-bodied species, sometimes with a slight nuchal hump (Ref. 35836). A stiff lower jaw, tapering towards a narrow, hypertrophied distal tip, covered with thick skin (Ref. 35836). The protruded mouth does not form a cylindrical tube (Ref. 35836). Long dorsal spine, 19-27% of SL (Ref. 35836). Anal and ventral fins are rather long, 19-24% and 18-21% of SL respectively, with a rather short pectoral-ventral length, 22-26% of SL (Ref. 35836). The caudal peduncle is deep, 11-12% of standard length (Ref. 35836). Scales: 12-14 predorsal scales (Ref. 35836). Live specimens are rather dark greenish brown, the back being darker, with usually greenish fins (Ref. 35836). In alcohol the basic color is a dull yellowish brown, the back being darker (Ref. 35836).

Labeobarbus osseensis especially occurs near rocky substrates in water of less than 3 m deep (Ref. 35836). It feeds on adult insects and macrophytes (Ref. 35836).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00933 (0.00422 - 0.02065), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 2.6 ±0.27 se; based on food items.

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).
