Abstract: The present investigation was conducted month-wise during July 2014 to June 2015 to analyze the phytoplankton and zooplankton community structure in the selected sampling stations on the River Meghna using various diversity indices. A total of thirteen sampling stations viz. Shatnol, Eklaspur, Ananda Bazar, Madrasa Ghat, Horina Ghat, Ishanbala, Haim Chor, Chor Voirabi of Chandpur district; Chor Jalalpur of Sariatpur district; Hizla, Kaliganj of Barisal district; Chor Ludhua, Chor Alexandar of Laxmipur district with corresponding GPS coordinates were selected on the River Meghna for plankton collection and analysis. The Shannon Index (H) for phytoplankton was found to be the highest in Axr (0.6829) and lowest in CV (0.5387). The Shannon Index (H) for zooplankton was found to be the highest in AB (0.4506) and lowest in Axr (0.6931). The Equitability Index (EH) for phytoplankton was found to be the highest in HG (0.9917) and lowest in CV (0.7772). The Equitability Index (EH) for zooplankton was found to be the highest in AB 0.65) and lowest in Axr (1.0). The Simpson Index (D) for phytoplankton was found to be the highest in HG (0.5057) and lowest in CL (0.6102). The Simpson Index (D) for zooplankton was found to be the highest in AB (0.722) and lowest in Axr (0.4992).The Simpson Dominance Index (D) for phytoplankton was found to be the highest in HG (0.4943) and lowest in CV (0.3537). The Simpson Dominance Index (D) for zooplankton was found to be the highest in Sn (0.278) and lowest in Axr (0.4693). Margalef Richness Index for phytoplankton was found to be the highest in Sn (0.1254) and lowest in Hz (0.09347). Margalef Richness Index for zooplankton was found to be the highest in Ep (0. 0.141) and lowest in CJ (0.1669).
