Etymology: Trematochromis: Greek, trematos = hole + Greek, chromis, = a fish, perhaps a perch (Ref. 45335).

Issue
The correct allocation to Haplochromis or Ctenochromis is pending further taxonomic studies (Ref. 57075).

Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 16 - 18; Radios blandos dorsales (total) : 8 - 10; Espinas anales: 3; Radios blandos anales: 7 - 8. Body deep and moderately compressed (Ref. 57075). Presence of a thick sensory canal on the six infraorbitals, with large openings that are widely separated from each other (Ref. 57075). Unicuspid outer and inner teeth on both jaws; outer teeth arranged in a single regular row; inner teeth smaller than outer teeth, arranged in three to six irregular rows on anterior part of upper jaw (Ref. 57075). Presence of 2 scale rows between upper and lower lateral lines (Ref. 57075). Scales ctenoid on flank; cheek scaled; dorsal and anal fins with scales at base; caudal fin with small scales anteriorly on fin membranes between rays; paired fins without scales (Ref. 57075). Upper lateral line high on body with 21-25 scales, lower lateral line running along body axis with 11-16 scales, two pored scales anteriorly on caudal fin (Ref. 57075).

The mouth is very protrusable which favor the idea of a planktonic diet (Ref. 7343).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.4 ±0.45 se; based on food items.

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).
