Abstract EN
A comprehensive ecological study was conducted on Al-hussainya river during the period from October , 2012 To Septemper 2013 .
This study includes measuring some chemical and physical properties of water , in addition to the study of Phytoplankton community quantitatively and qualitatively .The values of the parameters ranged between 12.7-31.
3 C°, 8.5-45C° for water and air temperature respectively , 7.
5-9.
4 for PH, 840-1416.67 μs / cm , 413.
33-700 mg / l , 6.
33-55.07 mg / l , 0.54 ‰-0.91 ‰ for each of electrical conductivity (EC ) , Total dissolved solids (TDS) , Total suspended solids (TSS) and salinity respectively , 11.
68 – 37.
77 cm / sec.
, 33.67-148.67 cm for each of water current velocity and water penetration respectively , 4.
97-12.
63 mg/l , 0.4-4.
84 mg/l for dissolved oxygen (DO) and BOD5 respectively.
Nutrients such as silica , total nitrogen and total phosphorous showed variation during this study , their values ranged between 1.
63-6.
26 mg / l , 1.
4-3.
5 mg/l and 1.33-17.
29 μg / l for each of them respectively .
A total of 242 taxa of phytoplankton identified during this study belonged to six classes of algae dominated by Bacillariophyceae which constitute 62.
81% of the total number of the species followed by Chlorophyceae by 20.
66 % and Cyanophyceae by 11.
16 % respectively .
Dinophyceae and Euglenophyceae constitute the 2.
07 % , while the the Cryptophyceae constitute the lower percentage which amounted to 1.
24 % of the total species , some genera like as Nitzschia , Navicula , Cymbella , fragilaria , Scenedesmus and Oscillatoria were dominated by their species numbers in the Phytoplankton community .The total numbers of Phytoplankton cells ranged between (446.
8-9177) × 103 cell / l recorded for March and October respectively .
