SAIYIDA
NAZNEEN
Abstract
An ecological survey of phytoplankton in
Kinjhar Lake was carried out form March 1968 to February 1971 at the surface and from March 1970 to February 1971 at various depths. Phytoplankton belonging to three algal
groups , Myxophyceae (22 species belonging to
12 genera), Bacillariophyceae (53 species belonging to 27 genera), Chlorophyceae (19 species belonging to 8 genera) were observed, Mycrocyslis aeruginosa was the most abundant species present throughout the year at the surface but the maximum growth was observed in summer. Melosira gramuleta and Spirogyra fuellebornei were next in abundance. Kinjhar lake is highly eutrophic due to the presence of nearly permanent bloom of Myxophyceae and significant growth of diatom species.
