Snorkelling surveys using a point abundance method revealed high levels of microhabitat differentiation among 14 fish species from a high‐visibility site in the middle reaches of the Gambia River. Habitat segregation was most strongly related to the position in the water column, flow velocity, substratum composition and presence of submerged wood.
