Datos del proyecto
High anthropogenic activities within the Mt. Elgon watersheds influence the degradation of aquatic health especially of the vital affluent rivers. The study conducted in March 2020 along rivers Chebonet, Sipi, Nabongo and Muyembe on the Western slopes of Mt. Elgon in Eastern Uganda investigated the status of Fish assemblage in relation to physical chemical parameters of water quality.

| Descripción del área de estudio | The study was conducted along rivers Nabongo and Muyembe located within the Mt. (mountain) Elgon region in Eastern Uganda. The rivers originate from the higher elevation areas in Kapchorwa district and drain the northwestern slopes of Mt. Elgon towards Bulambuli district, extending between 1.300 ̊ E - 1.400 ̊ E and 34.250 ̊ N - 34.500 ̊ N. Nabongo river joins Muyembe before the latter joins river Sironko which drains into Lake Kyoga via the Opeta wetland. The rivers flow through a mountainous terrain with an altitude-influenced climate (Bomuhangi et al., 2016). Altitude varies between 2080m above sea level on the upstream of the rivers, and 1100m above sea level downstream on the lowlands. The rivers transverse heavily cultivated steep slopes that are associated with heavy rains and a dense human population making the region vulnerable to environmental challenges such as soil erosion, siltation, landslides, pollution affecting the water quality of rivers and streams and in turn influencing the resilience of fish and other aquatic biodiversity. |
| Descripción del diseño | A sampling survey was conducted in March 2020 to obtain data on fish assemblage and physical chemical parameters of water quality from sections along rivers Nabongo and Muyembe. Sampling sites were selected based on accessibility of river sections and the land use practice in place. Two sampling sites, one on each river were selected. The sites were characterized by plantations of bananas, maize, sugarcanes, tomatoes, a market area and many homesteads associated with domestic waste disposal, washing and bathing, metal welding, and carpentry which were various point and non-point sources of pollution. The sites were considered with the highest level of anthropogenic disturbance. |

Métodos de muestreo
Fishing was done using an electric fishing equipment (HT-2000 battery Back pack electro fisher) at each sampling site. The electro fisher was run for 40 minutes across the river section at each site. Fish captured were collected in plastic buckets and sorted to the lowest taxon possible. Number and weight for each taxon were determined and recorded. Portable digital weighing scale and a measuring board were used to measure weight and length respectively.
| Área de Estudio | The study was conducted on rivers Nabong and Muyembe found along the western slopes of Mt. Elgon in Bulambuli district. Sampling sites were located along reachable river sections with observable anthropogenic activities. |

| Control de Calidad | Fish not identified to species level were fixed in 10% formalin in air tight containers and transported to the laboratory for a detailed taxonomic identification. In the laboratory, fish specimens were washed by soaking in tap water for 72 hours to get rid of formalin and then identified to species level with the guide of fish identification keys including Green wood 1966 and fish base online guide (https://www.fishbase.se/search.php. All scientific names were validated using FishBase (Froese & Paully, 2018) and the catalogue of fishes (Fricke et al. 2021). |
