Abstract
Primary productivity of brackishwater impoundments along Nethravathi estuary was
studied for one year from Feb. 1998 to Jan. 1999. The primary productivity values varied
from 1.78 to 13.47 mgC/m3/h and it exhibited a bimodal pattern of distribution with primary
peak in May followed by a secondary peak in September. Lower values were recorded during
monsoon season (June-Aug). Chlorophyll-a values observed to range from 2.83 to 9.71 mg/
m3 with higher values recorded during monsoon season and lower values in the month of
Dec/Jan. The seasonal trend of phaeopigment exhibited trimodal peak during March,
November and July
