Natural assemblages of marine bacteria are labeled with [ 3 H]thymidine, most of which is incorporated into the bacterial DNA. The method circumvents the problem of loss of label during short term feeding experiments. Highly labeled assemblages of bacteria thus obtained allow the measurement of grazing by microzooplankton with clearance rates as low as 1 µ l · individual −1 · d −1 .
