| Summary: | Environnemental Control of Shrimps Communities Structure along a Small West African Basin- Boubo River- Ivory Coast. The relationship between shrimps species and environmental variables were studied in Boubo River, a costal river in Ivory Coast. The river is submitted to the impact of human activities (dam construction and oils factory). This survey achieved for the first time in the Boubo River permitted to put in evidence nine freshwater shrimps species [Atya africana (Bouvier 1904), Caridina africana (Kingsley, 1882), Caridina nilotica (P. Roux 1833), Desmocaris trispinosa (Aurivillius 1898), Macrobrachium vollenhovenii (Herklots 1851), Macrobrachium macrobrachion (Herklots 1851), Macrobrachium felicinum (Holthuis 1949), Macrobrachium dux (Lenz 1910) and Macrobrachium sollaudii (De Man 1912)] belonging to two families (Atyidae and Palaemonidae) and four genera (Atya, Caridina, Desmocaris and Macrobrachium) were captured. Significant correlation between habitat characteristics and presence or absence of shrimps species suggest that rocky, leaves and death-woods substrates, canopy closure, width, depth and transparency were the main environmental variables influencing shrimps distribution.
