Classification / Names Common names | Synonyms | Catalog of Fishes (gen., sp.) | ITIS | CoL | WoRMS | Cloffa

Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Cichlidae (Cichlids) > Pseudocrenilabrinae
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).

Length at first maturity / Size / Weight / Age

Maturity: Lm 40.0  range ? - ? cm
Max length : 80.0 cm TL male/unsexed; (Ref. 102824); max. published weight: 4.5 kg (Ref. 681)

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 of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00693 - 0.03157), b=2.97 (2.80 - 3.14), 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.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.56; tm=2.5; Fec=10,000).
Prior r = 0.54, 2 SD range = 0.28 - 1.02, log(r) = -0.62, SD log(r) = 0.32, Based on: 1 K, 1 tgen, 1 Fec records
Vulnerability (Ref. 59153):  Moderate vulnerability (36 of 100) .
Price category (Ref. 80766):   Unknown.
