Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 16; Anal spines: 0; Anal soft rays: 15. Diagnosis: Nothobranchius mkuziensis can be distinguished from Nothobranchius orthonotus by a lesser body depth, lower number of scales on the mid-longitudinal series, 24-25 vs. 28-30, lower number of transverse scales, 9 vs. 11-12, and a different colour pattern of the unpaired fins, wide bars vs. small spots (Ref. 59344).

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=0.01000 (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).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

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