Paracalanus sp

The population dynamics and production rate of calanoid copepod Paraclanus sp. in Fukuyama Harbor, a eutrophic inlet in the Inland Sea of Japan were studied. The study indicated that Paraclanus sp. was present in the zooplankton population throughout the year. Egg production rates in the natural population was constant. Mortality between egg and NIII was high and fluctuating due to predation and the sedimentation of eggs from the water column.
