The dataset contains species occurrence for fishes from the mid Tana River Basin (Garrisa – Hola), Kenya.Purpose
The dataset was created as a contribution towards fish species occurrences records for the Tana River Basin Biodiversity Information System portalSampling Description
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.Sampling
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
