【 摘 要 】

In 2008, 33 species of Cladocers, Copepods and Rotifers have been observed in Sidi M’hamed Benali Lake (against only 12 species in 1992). The Copepods dominate in March, April, July, August and September, respectively with dominance (Do) equal to 56.6 %, 55.0 %, 55.0 %, 46.4 % and 90.0 %. Cladocers dominated in February (Do = 37.2 %), May (Do = 47.4 %) and December (Do = 48.6 %). The rotifers are extremely abundant and have a wide dominance in January (Do = 95.3%). The zooplankton population is very low in July and August. During the year, the population varies with temperature, water conditions, abundance of food and predation by fishes.
