I am not aware of any algae Key identification in your studied area.

Sorry,

You may have to contact relevant departments in Universities of your area. You can also enquire with Central Institute of Freshwater Aquaculture, Kaushalyaganga, as some of their scientists would have worked on the subject.

Dear Sunit,

what algae are you interested in? Only microalgae or also macroscopic ones? If so, there is an identification key for charophytes, available in the Internet, published in 1962 by Pal et al., entitled Charophyta. You can find there species which were found in Asia, including Bengal.

I am not familiar with any other keys, sorry.

Good luck,

Mariusz

Thank you Mariusz for interest and suggestion actually I would like to know about the common Microscopic and macroscopic fresh water algae normally grow in the water body of BEngal.

Sunit.
