Resumo: 	The method used consists of adding highly radioactive material (40 µCi/l NaH&lt;sup&gt;14&lt;/sup&gt;CO&lt;sub&gt;3&lt;/sub&gt;) to sea water with its natural concentrations of zoo- and phytoplankton, incubating this water in the light, separating zoo- from phytoplankton after 1h or at the most 2h and measuring the radioactivity of both. Under such conditions, the concentration of the tracer in phytoplankton can be simplified as a linear function of time, and that of the zooplankton as a parabolic function of time. This simplification leads to an overestimation of grazing of at most 2-3%. Comparisons with the Coulter Counter method are given and discussed.
