Etymology: Boulengerochromis: From George Albert Boulenger (1858-1937); he revised the works of Günther about Percoidei + Greek, chromis = a fish, perhaps a perch (Ref. 45335).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00684 - 0.03200), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.5 ±0.80 se; based on food items.
Generation time: 5.5 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.56; tm=2.5; Fec=10,000).
Fishing Vulnerability (Ref. 59153
): Moderate vulnerability (41 of 100).
Nutrients (Ref. 124155
