A one-year study on the standing crop in terms of chlorophylls, primary
production and total-cell counts of four station grids has shown that there were
regional and seasonal variations in the magnitude of phytoplankton production in
the Cochin backwater. Statistically treated using a microcomputor, a multiple
regression relationship has been established between parameters within stations.
But th<^ Correlation coefBclent and Standard Regression coefficient have revealed
that the plankton production and the related parameters at all the stations were
independent of each other and the parameters varied from station to station. Probable
reasons are briefly discussed
