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.

Biology     Glossary (e.g. epibenthic)

Inhabits near-shore surface waters. Firm flesh is highly valued (Ref. 4967). Largest African cichlid (Ref. 4537).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Deposits eggs in abandoned nests of other cichlids, in between stones, or in the sand, if no nests are available (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=0.01445 (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).
Price category (Ref. 80766):   Unknown.
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);
