Description The paper deals with the seasonal and spatial variation of phytoplankton,
based on the observations at four stations (Aroor to Fairway Buoy) in the Cochin
backwater during 1972-73. Two peaks of phytoplankton abundance are usually
observed, with the diatoms playing the major role in determining the pattern of
seasonal variations. An analysis of variance indicates that the spatial variation is
as high as the seasonal variation. The usefulness of chlorophyll a in relation to
the phytoplankton counts as a measure of the phytoplankton abundance has been
studied by using the correlation coefficients; it has been found from an analysis of
covariance that a common relationship exists between phytoplankton and chlorophyll
a for the estuary. The fluctuations in some of the environmental characteristics
have been discussed with their relative influence on thei production of
phytoplankton. In the light of the results obtained, outlines of modifications in the
sampling procedure have been given to the study of phytoplankton production
in the estuary more comprehensive.
