Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 9; Anal soft rays: 12 - 14; Vertebrae: 30 - 31. Melanorivulus rubroreticulatus is distinguished from all other members of the M. zygonectes group by its color pattern consisting of caudal fin with broad red bars in males, bars often interconnected to form reticulations and and anal-fin base with short red bars contrasting with intense light blue ground color (Ref. 96663).

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=0.00661 (0.00311 - 0.01404), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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