Datos del proyecto
The project aimed to provide information on habitat characteristics and the diversity of haplochromine fish species associated with the different habitats to strengthen the Environmental and Social Impact Assessment (ESIA) for the Isimba hydroelectric power dam (IHP).

| Descripción del área de estudio | The study area was the Upper Victoria Nile. The Upper Victoria Nile is part of the River Nile that connects lakes Victoria and Kyoga. The River Nile in Uganda flows over diverse habitats including rocky areas, falls and rapids, with marginal macrophytes provide suitable habitats for evolution of unique haplochromine taxa. The UVN has been reported to have some species that do not appear anywhere else in the World and are of conservation importance. The Upper Victoria is a hotspot of hydro electric power dams with four active dams. These dams threatened aquatic biodiversity. |
| Descripción del diseño | We selected sampling sites above and below existing dams (operating or under construction). Site Ripon falls/Bukaya and Lower Nava were above and below Nalubale and Kiira dams respectively. Kalange and Buyala were above and below Bujagali dam completed in 2012 respectively. Itanda, Kirindi, and Isimba were above Isimba dam while Mbulamuti and Kakindu were below the dam that was under construction at the time of the survey in 2016. It is important that Bujagali and Isimba dams are downstream Owen falls and Kiira dams in that order. Under each site, sampling stations were selected based on habitat characteristics. Habitats considered include rocky, sandy, muddy, vegetated areas. In areas where there were major falls with no dam such as Itanda, efforts were made to choose stations above and below the falls for sampling. The sampling sites and stations are described in detail in a report prepared after the survey (NaFIRRI, 2016). |

Métodos de muestreo
Fish sampling was carried out using monofilament gillnets of stretched mesh sizes 1 to 6 inches in increments of 0.5 inches. In habitats where gillnets could not be used, especially rocky areas, hooks of sizes number 18 and 20 were used. In a few cases, a beach seine was used. Since the emphasis of the study was on haplochromine cichlids, the fish had to be caught, examined, and photographed when still alive. Consequently, gillnets were set during daytime for one hour to facilitate identification of haplochromine species with their live colors. After hauling, individual fish specimens were photographed alive in a cuvette, using a digital camera and identified to the lowest possible taxon. Because most of the species endemic to the Nile River are un-described, those fishes that could not be identified to species level were given cheironyms.
| Área de Estudio | The study covered parts of the Upper Victoria Nile. The sampling was conducted in October and November 2016. |

| Control de Calidad | Photos were taken to facilitate identification of fish specimens. |
