Abstract

A study on occurrence and distribution of zooplankton, secondary production and
selected hydrographical characteristics was carried out for one year (April 1996
to May 1997) in Talapady lagoon near Mangalore Q2°47' N, 74-51' E). The
variations in secondary production and zooplankton biomass followed a bimodal
distribution with peaks during premonsoon and postmonsoon. Secondary production
varied between traces and 0.85 gC.nr3 and biomass between negligible and
14,45,000 no.nr3 during the period of study. Diel studies showed variations, with
higher production and biomass early in the day (0600 and 0900 h). Copepods (39%)
and nauplius (29%) dominated the zooplankton assemblage of the lagoon
