Abstract :

Macrozoobenthic community of Nagaram tank has been studied the species composition of benthos with different thermal conditions. The results revealed that the tank differ in the number of species of macrozoobenthic organisms. Quantitative assessments, seasonal variations and distribution of the macrozoobenthic community have been analyzed. There is a slight difference in species number between stations to station, but a considerable difference in species composition between seasons to season. The total 5 macro benthos species were recorded amongst which, 3 species from gastropod and 2 species from bivalve. Among gastropod, Indoplanrbis exustus, Bellamya bengalensis and Thiara tuberculate were present. During the study Lamellidens corrianus and Parreysia rugossa formed the main bulk of bivalve population almost thought the study period. About 54% of Gastropoda and 46% Bivalves were represented. Comparatively Gastropoda represented more population in the study period. In the present investigation, at all the sampling stations the highest population was in winter followed by summer and rainy season. As far as, seasonal abundance of benthos is concerned. It may be concluded that all the physico–chemical parameters are at nearly permissible limit at all stations. The overall tank is not considered as polluted one. The tank having rich diversity of flora and fauna, the tank water is suitable for fish culturing and irrigation purpose.
