Abstract:

The present investigation was carried out to assess the distribution of zooplankton in seagrass ecosystem in comparison with that of the coastal waters without seagrasses in Gulf of Mannar. Water and plankton samples were collected from the seagrass ecosystem (Station 1) and the control station without seagrasses (station 2) from September 2016 to May 2017. The physico chemical parameters were analysed and the mean values of surface water temperature, salinity, pH, dissolved oxygen, nitrite, nitrate, phosphate, silicate, gross primary productivity and chlorophyll-a were 27.72⁰C, 34.17 ppt, 7.99, 3.85 ml.l-1, 0.25µM, 0.01 µM, 0.63 µM, 1.03 µM, 0.22 mg.C.m-3.h-1 and 0.24 mg.m-3 respectively. Totally, 59 species of zooplankton were recorded from each of the two stations with the maximum density of 667400 and 935300 nos.m-3 in station 1 and 2 respectively. The higher density of zooplankton was observed during the summer months. The species richness and diversity indices showed the maximum values of 7.13 and 1.58 bits.ind-1 respectively in seagrass ecosystem which indicates that the diversity of plankton is more in seagrass ecosystem as that of the coastal waters without seagrasses.
