Detailed Ecological Assessment Report 2008 – Keenjhar Lake genus, Ankistrodesmus, Tetraedron, Spondylosium, one species of the each genus Crucigena, Arthrodesmus, Cosmocladium, Desmidium, were recorded. All the species are used as primary source of food for aquatic life. Arthrodesmus, Cosmoeladium, Desmidium, Closterium, Cosmarium reduces the hardness from water. Scenedesmus, Pediastrum and Crucigena are included in medicinal group. • Golden brown algae: 38 species belonging to 17 genera of the phyla Bacillariophyta in which 5 species of the genus Cymbella, 4 species of the genus Epithemia, 3 species of the each genus Synedra, Gomphonema, Gyrosigma, Navicula, Surirella, 2 species of the each genus Cyclotella, Cocconies, Mastogloya, Nitzschia, one species of the each genus Melosira, Fragiloria, Diplonies, Pinnularia, Rhopaldia, Cymatopleura, were recorded. • Dinophyta: 3 species belonging to 2 genera of the phyla Dinophyta 2 species of the genus Peridinium and one species of the genus Ceratium, were observed. • Flagellales group: 4 species belonging to 2 genera of the phyla Euglenophyta 2 species belonging to the each genus Euglena and Phacus, were observed. • Chrysophyta: 2 species belonging to one genus Dinobryon of the phyla Chrysophyta were recorded. These species indicate cold temperature of water. • Grass green algae: 7 species belonging to 6 genera of the phyla Chlorophyta, 2 species belonging to the genus Oedogonium and one species belonging to the each genus Cladophora, Coleochaete, Spirogyra, Zygnema, Ulothrix were observed. • Charophyta: Three species belonging to the genus Chara of the phyla Charophyta were observed. The species of Chara produce crop these species are excellent food producers. The species show natural indication for alkaline water. The species were used as food for cattle. When they are mature they release some smell to kill the mosquitoes. Chara is very common in our region. The climate conditions are favorable for this genus. This genus is included as cosmopolitan, the species of this genus were found from coastal area to near Khunjerab Pass and from Keenjhar to Karounger. 3.6.3 Comparison of summer and winter Table 20 below shows the algal species were recorded from Keti Bunder over summer and winter.
