Morphology | Morphometrics
Sarotherodon lamprechti is distinguished from all congeners by a lack of scales over the pectoralfin base. Further distinguished from its sympatric sibling species, S. knauerae, and other S. galilaeus populations, by a combination of a prognathous lower jaw and an elongate ventral keel on the lower pharyngeal jaw. It also differs from the sympatric S. knauerae in a lower gill raker number (20–25, mode 22 vs. 24–30, mode 28), longer pelvic fins reaching to (females), or beyond (males), first anal fin-spine (vs. not reaching beyond anus), from S. knauerae and other S. galilaeus populations and subspecies by long pectorals reaching the last anal fin-spine (vs. ending either in front of or at first anal fin-spine). Upper lip large and prominent (ULL 22.5–28.4 % HL vs. 19.1– 25.4 % HL in S. knauerae, 19.3–23.6 % HL in neighbouring riverine S. galilaeus, 18.9–24.2 % HL in S. g. borkuanus and 6.9–12.3 % HL in S. g. multifasciatus). Differs from S. g. sanagaensis in lower preorbital depth (16.3–25.2 % SL vs. 25.0–27.8 % HL) and from S. g. boulengeri in lower body depth (36.3–40.4 % SL vs. 44.5–50.0 % SL). Finally differs from phenotypically similar S. caroli and S. linnellii in lower gill raker number (20–25 mode, 22 vs. 18–20, mode 19 and 15–18, mode 18), and from other Barombi Mbo Sarotherodon in higher number of dorsal fin-rays (13–15, mode 14 vs. 10–12, mode 11) (Ref. 86429).
pelagic phytoplanctivore found in open water or on lake bottom in deeper zones; nuptial males excavate shallow pits with narrow rims over sand which serve as courtship territories and spawning sites; neighbouring males often engage in agonistic interactions between bowers; female mouth-brooder; reproduction takes place in the rainy season (August/September) (Ref. 86429).
