| Study Area Description | Tana River Basin is located in south eastern Kenya approximately between latitudes 0°0’53” and 2°0’41’’ South, and longitudes 38°25’43” and 40°15’ East, covering an area of about 95,000 km2 (Baker et al 2015). It is bordered by the Ewaso Ng’iro North Catchment to the north, the Rift Valley to the west, Athi Basin to the south and Somalia and the Indian Ocean to the east. The Tana River winds from its headwaters in the forests of Mount Kenya and the Nyandarua Ranges including the Aberdares and rapidly descends down the mountain slopes where there is intensive agriculture, then through the arid and semi-arid areas and finally terminates in a large delta at the Indian Ocean. The basin is generally divided into three distinct ecosystems that are recognized based on their elevation, climate and vegetation cover (Van Beukering and De Moel, 2015). The upper catchment above 1000 m a.s.l. consists of forested regions with high relief and higher rainfall. The middle catchment between 300-1000 m is flatter, drier and semi-arid to arid with rangelands that support pastoralism. The lower catchment below 300 m a.s.l. is semi-arid to moist at the coast with dry coastal forests and mangroves swamps and forms a delta with a large floodplain before discharging into the Indian Ocean. |
| Design Description | Field data from field expedition in the mid Tana, Kenya in September 2019. The specimens were deposited at the Ichthyology Section; National Museums of Kenya, where they were digitized. |

Sampling Methods
Beach Seining: This technique was only applicable in lagoon waters with flat bottoms. In this study a seine of 3x1.2 m net attached to two wooden poles of 3.18 cm in diameter and a size of 6.4 mm was used. Fish were trapped by encircling into the seine. The bottom lead line had lead weights strung or crimped onto it to give weight to the net whereas the top line had cork/polystyrene/plastic floats to keep the top of the seine near the water surface. Gill netting: Sampling of fishing in deeper portions of the sites and river was carried out by the use of nylon monofilament gill nets of various mesh sizes (25-100mm knot to knot). Gill nets capture fish by entanglement in a fabric mesh that is fixed vertically on the water column. The bottom of the mesh is attached to a lead line and top to a float line. Gill netting required two trips into the water, one to deploy the net and one to haul the fish
| Study Extent | Tana River county: Bububu wetland near Wenje, Jamhuri at Mkuruni and Ghabhia wetland at Malindi ya Ngwena near Hola. Garissa county: Bour-Algi near Garissa town. |
