Dear Osamiabe Ignatius,

the question you are asking about is too wide. In bioindiation you have to do with a short period and long period indication. The phytoplankton is short term, and macrophytes are long-term indicators. So, please, note what indication you are asking about - saprobiological or toxicological. I'm sending you some books mainly in Russian but can understand as have good tables.

Dear Osamiabe Ignatius ! I very much recommend the works of V.G. Papchenkov. In particular: Papchenkov V.G. Dynamics and indicative properties of vegetative cover of waters // The ecological condition of small rivers of the Upper Volga region. M., Science, 2003. P. 187-211. (Russ.).

Search the Internet ! Maybe you'll find something in English.

Nikolay

Thanks Nikolay
