Abstract: The present investigation was carried out on Vembanad lake in the Eramalloor region of Ernakulam district, Alappuzha, Kerala. The study was carried out for a period of 11 months from September 2015 to July 2016. During the study, the average temperature was 29.0ºC, average salinity was 19.02% highest salinity was observed in the month of April, the average transparency was 71.60 cm and the lowest dissolved oxygen was observed during the month of March 3.8 mg/l, pH was observed maximum in the month of May (8.1) and minimum (6.2) in the month of October. The average alkalinity was 90.98 mg/l, Nitrate ranged between 16.3µg/l and 4.7µg/l and average of 9.56µg/l. Phosphate ranged between 1.01µg/l to 5.8µg/l. Premonsoon season showed peak salinity whereas, mesohaline nature was found throughout study period.
