Africa: from the middle Congo River basin (Kasai drainage and between the Lomami and Kisangani) up to the upper Lualaba and the Bangweulu area (Ref. 55074). Also in Lake Malawi, Zambesi, coastal areas from Zambesi Delta to Natal, Okavango and Cunene (Ref. 5163) as well as the Limpopo, Malagarasi (Ref. 55074) and Lake Tanganyika (Ref. 55074, 74387). Also present in the Cuanza and Catumbela rivers in Angola (Ref. 11970). Introduced in Lake Kivu, escaped from fish ponds (Ref. 107916). Introduced elsewhere usually for weed control and aquaculture. Several countries report adverse ecological impact after introduction.

Short description Μορφολογία | Μορφομετρία

Ραχιαίες άκανθες (συνολικά): 15 - 17; Μαλακές ραχιαίες ακτίνες (συνολικά): 10-13; Εδρικές άκανθες 3; Μαλακές εδρικές ακτίνες: 9 - 10; Σπόνδυλοι: 29. Diagnosis: A large, deep-bodied species with a steep head profile, narrow head and small mouth; often appearing brownish with a white belly, some individuals have bright red bellies (Ref. 118638). The sexes look very similar, although males are usually larger (Ref. 118638). Very difficult to distinguish from Coptodon zillii, but C. rendalli usually have a steeper head profile and less prominent vertical bars; in East Africa, the tailfin of C. rendalli is often divided into a brownish upper part and yellowish lower part, whereas that of C. zillii is uniform and spotted (Ref. 118638).

Βιολογία     Γλωσσάρι (π.χ. epibenthic)

It prefers quiet, well-vegetated water along river littorals or backwaters, floodplains and swamps. They are tolerant of a wide range of temperatures (8-41°C) and salinities (Ref. 3, 7248, 118638). Forms schools; is mainly diurnal. Juveniles feed on plankton (Ref. 52307); adults feed on leaves and stems of underwater plants as well as algae, and vegetative detritus (Ref. 52307), insects and crustaceans. A substrate spawner; male and female form pairs to rear the young; eggs and larvae are usually guarded in a steep-side circular pit dug in the mud (Ref. 118638). Occasionally it spawns in large cave-like structures (Ref. 52307), e.g. in Lake Malawi they are reported to dig a network of tunnels at some sites (Ref. 118638). Make excellent eating (Ref. 5214). Widely exploited in fisheries and aquaculture (Ref. 118638).

Life cycle and mating behavior Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Αβγά | Γονιμότητα | Προνύμφες

Prefers a sloping spawning ground near the marginal fringe of vegetation (Ref. 3). Builds nest in shallow water where both parents guard the eggs and young.
