Abstract: Wetlands under extreme threats are more in Kerala than any other state. The present study focuses on the four selected stations of Thekkumbhagam creek for the analysis of its primary productivity. The assessment of primary production of this creek is necessary to make out whether the productivity recorded is enough to sustain its biodiversity. The stations recorded a productivity range from 0.15 mg C/l/day to 8.8mgC/l/day. Station 2 recorded the maximum rate of gross primary production. Maximum production was noticed in the post-monsoon period and minimum during the monsoon period. Gross primary production and net primary production below detectable levels were also noticed. The depletion of dissolved oxygen in the surface water and bottom water caused the total failure of production especially in polluted areas. Thus a “scientific knowledge” about the water quality of the “Thekkumbhagam creek” will help in the understanding of the economic, cultural, social, aesthetic, spiritual values and all other benefits thereby focusing the mitigation of pollution affecting the creek.
