Abstract

Distribution of phytoplankton pigments were studied during Feb. 1993 - May
1994 in the Nethravathi estuary, Mangalore. Chlorophyll a, b and c varied between
1.18 - 11.35 mg/m3, 0.12 - 14.88 mg/m3 and 0.08 - 25.82 mg/m3 respectively
with higher concentrations during May, June - July and Nov. - Dec. The
carotenoids varied between 0.01 and 16.31 mg/m3 with peaks during Oct. - Nov.
and March - April. Variation of pigments are due to temperature, salinity and
nutrients in the Nethravathi estuary.
