Statistical approaches for computing diversity and density of zooplankton with water factors in Mula Dam, Rahuri, MS, India

Anant J. Dhembare

This paper tended the seasonal density and diversity of zooplankton in Mula dam a freshwater body during 2007-09. Zooplankton showed seasonal variations. Over all density was higher in rainy (35.3%) > summer (34.1%) > and lowest in winter (30.7%). The zooplankton distribution constitutes rotifer (48.9%), cladocera (18.9%), copepoda (13.1%), decapoda (10.9%) and protozoa (8.2%). The rotifer dominated among the zooplankton organisms. Also statistical parameters such as standard deviation, sum of error, covariance, etc documented. The density and diversity of zooplanktons was also discussed with physico-chemical parameters of water. The diversity and density of zooplankton depends upon the nutrient condition of water body, abiotic factors, food chain and web with life cycle.
