摘要：The value of primary productivity reflects the ecological health of an aquatic ecosystem. Considering this, the in situ measurement of primary production and production respiration were made using light and dark bottle in the Thol Wetland Bird Sanctuary during the year 2015 - 2016 covering winter, summer and monsoon seasons. The total productivity ranged from 12.45 g C/m3/d to 0.3 g C/m3/d having maximum value in summer and minimum value in monsoon. The production respiration ratio ranged from 2.06 to 0.032 having maximum value in summer and minimum value in monsoon. Factors affecting the Primary Productivity and Photosynthesis Respiration ratio in an aquatic ecosystem are mainly light, nutrients, hydrographic conditions, temperature, turbidity, solar radiation and plankton density.
