In order to contribute to the evaluation of the biodiversity and growth of fish species in the Congo River, a study was conducted in Kindu in the Democratic Republic of Congo, from January 14 to June 28, 2019. The objective was to identify commercial fish species and assess their growth. For the realization of this study, a pre-survey and field observations were carried out at the central Beach of Kindu, place of sale of caught fish which were the subject of our study during the rainy season.

In fact, 110 specimens were caught with hawk nets, monofilament gill nets and hooks (n ° 16, 18 and 20).The results obtained showed that six species of fish of commercial interest were inventoried: Distichodus engycephalus (24.5%), Synodontis decorus and Auchenoglanis occidentalis (with 20.9% each), Oreochromis niloticus and Sarotherodon galileus (commonly 15, 5%) and finally Labeo macrostomus (2.7%). Oreochromis niloticus, Sarotherodon galileus, Distichodus engycephalus, Labeo macrostomus and Auchenoglanis occidentalis had positive allometric growth Relations longueur..... Ngoy A Ngoy Chuck et al. (83.3%) and Synodontis decorus, isometric growth (16.7%). Thus, all of the species of fish of commercial interest studied adapt well to the environmental conditions of the environment. Therefore, subsequent studies on the biology (diet and reproduction) of these fish species are however necessary in order to consider their domestication.
