Marcusen, author of "Zur Phauna des Schwarzen Meeres", 1867; ichthyologist; kaninginii: Marcusenius kaninginii is dedicated to Professor Boniface Kaningini Mwenyimali, director of UERHA and rector of ISP/Bukavu; he supported in various ways the sampling expeditions of Tchalondawa Kisekelwa in the Lowa system (Ref. 113607).

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 18 - 23; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 27 - 30; позвонки: 42 - 44. Diagnosis: Marcusenius kaninginii belongs to the group of Marcusenius species with eight large circumpeduncular scales (Ref. 113607). Within this group it can be distinguished from M. dundoensis, M. fuscus and M. sanagaensis by its lower number of lateral line scales, 43-47 vs. 49-61; it differs from M. ghesquierei and M. kutuensis by having fewer dorsal-fin rays, 18-23 vs. 27-34; and from M. schilthuisiae by fewer anal-fin rays, 27-30 vs. 32-35 (Ref. 113607). It is distinguished from M. intermedius by a higher number of lateral line scales, 43-47 vs. 38-43, and a higher total vertebrae number, 42-44 vs. 40-41; furthermore, it can be distinguished from M. intermedius by the terminal mouth position and the rounded shape of the snout vs. mouth sub-terminal and the snout pointed; it is distinguished from M. moorii by the blackish longitudinal band along the lateral line; the shallower body at the anterior base of the anal-fin depth, 25.0-28.4% of standard length vs. 28.1-33.5; the shorter pectoral fin, 15.5-19.1% of standard length vs. 17.7-22.8; and the deeper caudal peduncle, 39-57% of its length vs. 27-42 (Ref. 113607).
Found in shallow water, ±1-2 m), near the shores; it has been collected at stations with low water velocity, near roots of vegetation or dead wood and at places with foliage-shade (Ref. 113607).
