In Algeria, little work has focused on the study of spiders. Fetzara Lake which is a wetland located in north eastern of Algeria, covers an area of 20680 hectares. This has encouraged the development of several plant species in the lake and the borders of the lake. This particular ecosystem allowed the installation of arthropods in the edges of the lake, including spiders.
The objective of this work was to make an initial inventory of spiders occupying the edges of Fetzara Lake, and draw up the first list of species that characterize the region. An inventory was conducted in Fezara Lake (Annaba Algeria) during a period running from December 2013 to November 2014. The inventory revealed the presence of 38 species belonging to 15 families Araneidae, Dysderidae, Clubionidae, Gnaphosidae, Liocranidae, Lycosidae, Oxyopidae, Palpimanidae, Pisauridae, Salticidae, Scytodidae, Tetragnathidae, Theridiidae, Philodromida and Zodariidae. Very high species richness was observed in the Araneidae family with 07 species, while the family Gnaphosidae recorded 06 species. Lycosidae and Philodromidae families were represented by four species each. Three species were recorded for each family in Dysderidae and Salticidae. Pisauridae and Theridiidae revealed two species each. And the rest of the families marked their presence by a single species each. The number of the identified individuals was 432 adult specimens. The most encountered species were Pardosa sp and Araneus diadimatus.
