Abstract

Hydrilla verticillata, (in Arabic Qotel in some area) is an exotic and invested aquatic plant for Iraq. It is recently decovered after inundation of Abo-Zaraq marsh, therefore its ecology and distribution are the amis of this study.The results of this study showed that H. verticillata has different reproductive stratigies and a very high potential of invation of different habitat, and can easly grow and withstand in it. For that reson H. verticillata quickly succeeded to expand its distribution through almost all marshes areas including Shatt Al-Arab water way reaching to Abo Al-Khasib.Cover percent, Biomases and the yield of a year production were determined.
