ECOLOGICAL STUDY ON A FRESH WATER POND IN GWALIOR, M.P.

Planktonic distribution of a Govind puri, sewage fed and perennial pond at Gwalior was studied during July 1992 to June 1993. A total of ninty taxa were identified out of which 59, were to phytoplankton (23 taxa of Chlorophyceae 25 taxa of Euglenophyceae, 07 of Cyanophyceae and 04 taxa of Bacillariophyceae) and 31 species of Zooplanktonic forms (10 species of Protozoa, 16 species of Rotifera ; 02 species each Ostracoda and Cladocera and 01, species of Copepoda). Seasonal distribution of these species and their relationship with some physico-chemical characteristics were also defined. Phytoplankton and zooplankton peaks do not occcur simultaneously with dominance of euglenoids and rotifers.
