Study the zooplankton population in relation to physico-chemical factors of sewage fed pond in Darbhanga

Abstract

The water body is receiving domestic discharge leading to large amount of nutrient inputs and high amount of phosphate and nitrate in the water body indicates the Plankton biodiversity is a fundamental research area in the aquatic ecological studies and it is used for the variety of marine ecological problems, such as protection of biodiversity, bionetwork roles and services. Therefore, the phytoplankton is involving the various ecological processes with influence the species diversity. The present studies were made on the diversity of phytoplankton in relation to Physico-chemical parameters with respect to pollution status of Ennore mangrove ecosystem, Bihar, India. Surface water samples were collected from six different locations of Ennore at monsoon, post monsoon, summer and pre-monsoon seasons. A total of 101 species of phytoplankton observed belonging to different taxonomic groups were identified, out of which 48 species belong bacillariophyceae, 34 species to cyanophyceae and 19 species to chlorophyceae.
