A freshwater perennial pond Jorhat district of Assam was investigated for nine months during the year 2019 to gather preliminary information on the assemblage pattern of phyto and zooplankton. A total of 99 plankton species was recorded during the study of which 58 were phytoplankton and 41 belonged to zooplankton. Phytoplankton community was composed with 41.38% Chlorophyceae, 37.93% Bacillariophyceae, 10.34% Euglenophyceae, 8.62% Cyanophyceae and 1.72% or single species of Dinophyceae. Diatom genus Navicula was the speciose one. Zooplankton community dominance was Protozoa (31.71%) > Rotifera (29.27%) > Cladocera (17.07%)> Copepoda (14.63%). Three arthropod zooplankton, not belonging to these categories were grouped as Insecta which contributed 7.23%. One of the significant findings during the investigation was the presence of Freshwater Tardigrade in the pond, in the situation where global information on freshwater Tardigrade is scanty and in Indian context, it is close to zero. This report provides the first photographic documentation of Tardigrade from Northeast India.
