A Study on Diversity of Phytoplankton and Ecological Features of Temple Stream of Kasipatnam, Visakhapatnam (Dist), Andhra Pradesh, India

Abstract

The present study was to enumeration details of the phytoplankton diversity and ecological features of Kasipatnam Temple Stream, Kasipatnam, Anathagiri Mandal, Visakhapatnam (Dist), Andhra Pradesh, India. During one year period on May 2020 to April 2021. Present observation of ecological features such as water temperature, weather temperature, rain fall, humidity and wind analyzed at Kasipatnam Temple Stream. The phytoplanktonic number decreased during monsoon season and increased very quickly during post-monsoon months. In monsoon season the phytoplankton communities value were low. Because high inflow of water in this season. Investigation of the Kasipatnam temple Stream revealed that the total number of 30 genera and 58 species belongs to four classes such as Chlorophyceae, Bacillariophyceae, Cyanophyceae and Euglenophyceae. Most number of the chlorophyceae classes have 15 genera and 28 species, Bacillariophyceae have 9 genera and 12 species, Cyanophyceae have 4 genera and 10 species and Euglenophyceae have 2 genera and 6 species. The present observation revealed that chlorophyceae species were dominant followed by Bacillariophyceae, Cyanophyceae and Euglenophyceae.
