Short description Identification keys | Morphology | Morphometrics

Vertebrae: 36 - 37. Differs from its congeners by possessing the supraorbital sensory pores s6 placed close together, a narrow opercular patch of developed odontodes, with 8-10 odontodes, and 8 branched pectoral rays (Ref. 56791).

Found mainly in fast moving clear water (Ref. 56791).

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=0.00977 (0.00400 - 0.02388), b=3.04 (2.84 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming Fec < 100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
