Issue
This species is placed in the genus Haplochromis Hilgendorf, 1888 in Eschmeyer (CofF ver. Mar. 2012: Ref. 89686). We keep the lacustrine and riverine "Haplochromine" species in the genus Haplochromis only for the Lake Victoria catchment following Van Oijen et al. (1996: Ref. 12750), until a new complete taxonomic revision is published.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic. Tropical; 24°C - 28°C (Ref. 2059); 17°N - 12°S
Africa: restricted to the coastal river systems of Tanzania; although this species is also reported from other localities in Kenya, Uganda, the upper Niger River and probably also the Nile River, these populations are considered as not conspecific (Ref. 13338). Reports from Lake Chad basin (Ref. 53405) refer to Astatotilapia tchadensis (Ref. 112399). IUCN listed Haplochromis aff. bloyeti as data deficient (DD).

Found in rivers, streams and small freshwater lakes (Ref. 4967). Ovophilic, agamous maternal mouthbrooder (Ref. 52307).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [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): 3.1 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
