Fish capture was carried out for a period of 5 months between January and May 2016. Three different capture techniques were used including a battery of six monofilament net of large mesh (8, 10, 12, 15, 20 and 30 mm) and each net was 30 m long and 1.5 m high. The aim of this study was to list fish in different affluents of Tshopo River in order to bring out recent data on the specific diversity of fish fauna and to compare fish specific diversity of these two rivers for a rational and sustainable management. In Makwamboli river, 1 258 specimens of fish distributed in 5 orders, 11 families, 19 genera and 25 species were inventoried and 601 specimens of fish were captured in Ngene-Ngene River are distributed in 5 orders, 10 families, 17 genera and 19 species. The same species found in both rivers show the resemblance between the fish fauna of Mukwamboli and Ngene-Ngene rivers which both are sub-affluents of Tshopo Rivers. Among species inventoried in both rivers during our research, 18 species are listed as a minor concern and two insufficient data in the red list of IUCN (2016).
