Abstract
This study concerns the aquatic fauna of wells in a semi-arid region of north-eastern Algeria. Five
wells were selected and seasonal sampling of the aquatic fauna and water of these wells was
carried out from September 2017 to June 2018, covering periods of high and low water. Two types
of traps were used: the phreatobiological net and baited nets. The physico-chemical analyses of the
wells’ water showed that the majority of groundwater in this region is of poor quality,
undersaturated in oxygen and highly mineralized. The fauna of the wells is composed of 21 taxa
and 4562 individuals, dominated by Insects 56% followed by Crustaceans 25%. Only one species
was found as a stygobian species Pseudoniphargus sp.
