“…The principal species found in the Boukourdane Lake Dam were consistent with those described by other studies performed on the Algerian aquatic ecosystem (Samraoui et al, 1998;Cherbi et al, 2008;Bouzidi et al, 2010;Hamaidi et al, 2010;. The rotifer results are consistent with those of Zanata and Espindola (2002), who found them to be dominant during the dry period.…”

The impact of seasonal variations in the water physico-chemical parameters on the zooplankton and phytoplankton composition was investigated in the Boukourdane reservoir (Tipaza, Algeria) over two years (April 2005-March 2007. High levels of nitrites were observed during the cold seasons, and the phosphate levels were higher in summer with a very high NO 3 -/PO 4 3ratio (>30) in winter. A significant increase in the level of chlorophyll a (Chl a) was observed in spring. The relative standard deviations (RSDs) highlighted a large variability during the warm seasons, especially for nitrites, nitrates, phosphates and ammonia. A great species diversity was observed (rotifers: 79, copepods: 13, and phytoplankton: 83). The weighted averages of the species enabled us to determine the optimal values of their physico-chemical parameters, as elevated temperatures for Bacillariophyta and Pyrrhophyta or high concentrations of chlorophyll a for Charophyta. The zooplankton was more prevalent during the spring and appeared to be correlated with sulfates and electrical conductivity. A redundancy analysis (RDA) corroborated the previous results and explained 84.1% of the total variance. This analysis highlights the influence of some of the environmental variables on the seasonal distribution of plankton, characterized by a high profusion in spring and scarcity in autumn and winter.

A study of zooplankton diversity and water quality of Lake Dogodogo located in West Burundi was carried out from April to July 2021 in six sampling stations, with four selected in the littoral zone and two remaining in pelagic one. The main objective was to assess the water quality using zooplankton diversity indices for a better management of this fishery resource essential for the surrounding populations. The zooplankton sampling was collected twice a month between 8 A.M and 11 A.M each time. The samples were taken vertically using plankton net with a 50 µm of mesh size, 26 cm in diameter and 0.5m depth. We recorded 30 zooplankton species, 19 of rotifers, 9 of copepods and 2 of cladocerans. The number of species varied from one station to another and from the littoral zone to pelagic zone. The abundance of zooplankton was higher in the pelagic zone than the littoral one. We then highlighted species specific for pelagic zone, such as Anuraeopsis fissa, Brachionus angularis, Brachionus calyciflorus, Brachionus falcatus and Keratella tropica. These latter are indicators of a high trophic level. According to the diversity indices calculated, the Dogodogo’s water quality is moderately polluted by a low level contamination of agricultural origin. Therefore, it is necessary to protect this important resource for fish production purposes, which is essential in protein supply for human life.

Our work consists in characterizing the phytoplanktonic biodiversity of lake Sidi Mhamed Benali, also, biotic parameters were employed to assess lake trophic conditions, by Multivariate Analysis and by the ecological indices, during the period which extends from March to May 2021.The results of the phytoplankton analysis allowed us to list 89 species divided into 6 classes (Diatoms, Chlorophyceae, Euglenophyceae, Cyanophyceae, Cryptophyceae and Dinophyceae).The general composition of the phytoplankton of the lake is dominated by Diatoms with 34 taxa, or 36.62% of the phytoplankton community, represented mainly by the following genera: Cyclotella, Nitzschia and Fragilaria, followed respectively by Chlorophyceae with 25 taxa, or 31.81% of the total population, they are represented mainly by Oocystis, Tetraspora and Closterium, Eugenophyceae with 13 taxa, a proportion of 12. 82%, the Cryptophyceae: groups 5 taxa, with a proportion of 10.44%, the Cyanophyceae: counts 9 taxa, with a proportion of 6.88%, the Dinophyceae which groups 3 taxa, with a proportion of 1.42%. Moreover, the waters of the lake are classified as waters of average quality and are in as hypereutrophic state.
