Studies on Physico-chemical nature and diversity of phytoplankton in Chickan Lake, District Dadu, Sindh

Abstract

Chickan Lake is one of the oldest lake in vicinity of Dadu district, Sindh. It holds the water throughout the year and importantly counted in saline water lake, the salinity reaches up to 9.5 ‰ in winter and decline 6.0%. Because there is not enough literature on this particular lake a study was conducted in 2015 to 2016, for the determination of physical, chemical and biological characteristics in different seasons in monsoon and winter. During the study all physico-chemical parameter were higher in winter than those of monsoon season. Plankton studies reviled that the total 20 species belong which is covering 4 classes. Cyanophyceae comprised of 7 species followed by Chlorophyceae 6 species, Bacillariophyceae 4 species and Euglenophyceae 3 species were recorded. Growth of cyanophyceae is dominated over bacillariophyceae, euglenophyceae and chlorophyceae
