BIOMASS AND BIOCHEMICAL-COMPOSITION OF ZOOPLANKTON FROM NORTHWEST BAY OF BENGAL DURING JANUARY 1990

Biomass, proximate composition, organic carbon and calorie content of assorted zooplankton from the surface waters were studied. Day and night stations revealed significant difference in biomass (displacement volume, dry wt and organic carbon) whereas at coastal and oceanic stations irrespective of day and night the difference was significant only in dry wt values. Protein and organic carbon content peaked at 14-degrees-16-degrees-N. Average calorific content was 4.05 kcal.g-1 dry wt. High lipid content at 12-degrees-14-degrees-N correlated with maximum chl-a.
