Journal Title: GJRA-Global Journal For Research Analysis - Year 2018, Vol 7, Issue 3
Abstract
Present study was undertaken to analyse the qualitative and quantitative variations in abundance and diversity indices of zooplankton of Bhakra –Yamuna link canals in the Narwana region, Haryana. For analysis, samples were collected from three selected sites (S , S , and S ) on Bhakra-Yamuna Link canals for a period of one year from January to December, 2013. For 1 2 3 diversity index, Shannon and weaver diversity index, Simpson dominance index and Pielou evenness index were used and to calculate similarity index between selected sites, Jaccard similarity coefficient was used. Result revealed that a total of 13 species of zooplanktons were recorded belonging to group protozoa, rotifera, cladocera and insecta. Population density of zooplankton was low at site S and higher 1 at site S .The diversity indices revealed a signicant decline in the population of zooplankton from site S to S after linking with site S . 2 2 3 1 Similarity coefficient was more between S and S as compare to site S and S and site S and S . Cladocerans were dominant at site S and 2 3 3 1 1 2 1 Protozoans were dominant at site S .
