Diversity And Distribution Pattern Of Zooplankton Of River Torsa, West Bengal
Subject area: Agriculture and Veterinary Sciences · Area of research: Zoology
Abstract
A survey was carried out from February 2014 to March 2016. Water samples were collected in a monthly interval. . Biodiversity indices like Shannon?s diversity index, Pielou?s evenness index, Simpson?s dominance index and Margalef?s species richness index were calculated. A total of 16 zooplankton genera were recorded composed of Protozoa with 4 genera, Rotifer with 5 genera, Cladocera with 4 genera and copepod with 3 genera from the river Torsa. Rotifer was most dominant group (31%) and copepod was least dominant group(19%). Density (org./L), number of organism (S), species diversity index(H?) and Margalef?s species richness Index (R) of zooplankton were recorded maximum in winter season and minimum in monsoon season at all sites.
