Africa: Lake Malawi, rivers flowing into it and the upper Shire River (Ref. 39192, 55954, 79521, 97235). Translocated to the upper Ruo River in Malawi and also to Swaziland (Ref. 7248).

Length at first maturity / Size / Weight / Age

Maturity: L_m 26.5, range 25 - 27.5 cm
Max length : 56.0 cm TL male/unsexed; (Ref. 40637); max. published weight: 6.1 kg (Ref. 7248)

Present in calm coves or slow flowing sections of rivers with vegetation; not common in Lake Malawi, but abundant in larger rivers (Ref. 4967). Mostly found near river outlets and in the southern part of Lake Malawi; most frequently observed in the shallows of Lake Malawi; found over sandy and vegetated areas as well as over rocky substrates; piscivore, hunting mbuna and sand-dwelling haplochromines; mouthbrooder (Ref. 5595). Oviparous (Ref. 205). Breeds in summer (Ref. 7248).

Oviparous (Ref. 205). Females incubate the eggs in the mouth (Ref. 50828).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01349 (0.00767 - 0.02371), b=3.00 (2.85 - 3.15), based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 4.1 ±0.67 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.51; tm=3).

Prior r = 0.48, 2 SD range = 0.21 - 1.10, log(r) = -0.73, SD log(r) = 0.41, Based on: 2 K, 2 tgen, 1 Fec records

Vulnerability (Ref. 59153): Low vulnerability (25 of 100) .

Price category (Ref. 80766): Unknown.
