The epiphytic algae on some aquatic macrophytes and related physical and chemical
properties of Al-Abbasyia-Euphrates river middle of Iraq were studied during the
study period from March 2012 to February 2013. Four sites between the Al-Kifil
districts extending to the Al-Abbasyia district selected.
The quantitative and qualitative of epiphytic algae on Phragmites australis and
Ceratophyllum demersum have studied. In addition to many physical and chemical
parameters such as air and water temperature, water flow, transparency, pH, electric
conductivity (EC), Salinity (‰), TDS, TSS, dissolved oxygen, BOD5, alkalinity, total
hardness, calcium and magnesium. A total of 209 epiphytic algal taxa belonging to
Bacillariophyceae (144), Chlorophyceae (39), Cyanophyceae (19) and
Euglenophyceae (2) recorded within the present study. Some algal taxa noticed
mostly dominant among both the study sites and periods. These were Cymatopleura
elliptica, Eunotia arcus, Nitizschia sp., Cymbella sp. and Gomphonema sp. This study
revealed the existence of some algal taxa on specific parts of the host macrophytes.
Where Sphaerocystis attached on the stem of C. demersum; Actinoptychus sp.
attached on the root of P. australis; Chaetoceros capense on the root of P.australus
and Thalassiosira fluviatilis on the leaves of P. australis.
