The connection between marine phytoplankton and fishery carbon sink is discussed in this paper. Furthermore, the phytoplankton related fishery carbon sink parameters, including phytoplankton primary productivity, carbon biomass, specific growth rate and its grazing mortality rate by microzooplankton, are highlighted. For each parameter, its common measuring methods were briefly described. Essentially, the fishery carbon sink is a major branch of phytoplankton carbon sink,and its calculation and measurement is the same as that of carbon flux of marine ecosystem.
