Correlation between the diversity and primary production index of phytoplanktons of Pechiparai Reservoir in Kanyakumari District, TN, India was assessed from January to December 2004. Average phytoplankton primary production varied significantly during the period of study. Maximum diversity and primary productivity were record in the months of Jan to Mar. The inflow of water during the monsoon into the reservoir was the prime factor that influenced input of the nutrients and appeared to enhance the primary production during this period. Shennon – Weiner diversity index varied between 1.242 and 1.897 during the period of study. Likewise, Sympson index varied from 0.822 to 0.898 and evenness from 446 to 956. The value of annual average of phytoplankton biomass was 319 Nos-1. The value of annual average of gross primary production and net primary production were 2719 mg C/m3/d and 1610 mg C/m3/ d respectively.
