摘要：

1. The grazing of [methyl-3H]thymidine-labelled bacteria by zooplankton was studied in Lake Norrviken, Sweden. 2. Animals did not ingest bacteria attached to large colonies of the cyanobacterium Microcystis wesenbergii Kom. but small aggregates of bacteria and free bacteria were readily consumed. 3. Diaphanosoma brachyurum (Lievin), Daphnia cucullata Sars, and Daphnia galeata Sars grazed free bacteria more quickly than aggregates, but Eudiaptomus gracilis (Sars), Chydorus sphaericus Mull, and Bosmina coregoni s.l. Baird grazed the aggregates more readily. 4. Filtering rate determinations varied from 1.6 to 125 .mu.l ind.-1 h-1 for various species.
