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).
Eponymy: George Albert Boulenger (1858–1937) was a Belgian-British zoologist at the British Museum, London. [...] (Ref. 128868), visit book page.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 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: 2.0 ( na - na) years. Estimated as median ln(3)/K based on 1
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 to high vulnerability (52 of 100).
Nutrients (Ref.
124155): Calcium = 77.4 [35.8, 153.1] mg/100g; Iron = 1.7 [0.9, 3.4] mg/100g; Protein = 19.8 [18.1, 21.3] %; Omega3 = 0.549 [0.199, 1.613] g/100g; Selenium = 70.3 [28.3, 170.8] μg/100g; VitaminA = 38.8 [8.5, 138.3] μg/100g; Zinc = 1.09 [0.73, 1.74] mg/100g (wet weight);
