Africa: Lake Tanganyika (Ref. 2216, 36901); widely distributed throughout the lake (Ref. 36901). In the Lukuga River (Lake Tanganyika outflow), known up to Niemba (Ref. 93587). In the Malagarazi River, known from the delta and the lower reaches (Ref. 54847).
Length at first maturity / Size / Peso / Age
Maturity: Lm 45.5 range ? - ? cm
Max length : 80.0 cm TL maschio/sesso non determinato; (Ref. 3636)
Juveniles live in a specific inshore habitat until they reach 18 cm, thereafter they adopt a benthic habitat moving into deep water (Ref. 2216). Juveniles have been observed near or in affluent rivers (Ref. 36901). Top predator in depths below 100 m; exploits both fishes and invertebrates; migrate diurnally to surface to feed on pelagic clupeids; highly susceptible to intensive fishing (Ref. 2216).

50 = 0.5006 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00582 - 0.01719), b=2.99 (2.84 - 3.14), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.2 ±0.69 se; based on food items.
Resilienza (Ref.

Fishing Vulnerability (Ref.
