| 摘 要： | The transfer of 137C3, 60Co along Platymonas sp., Brachionus plieatilis Muller and Tilapia mos-sambica Peters was studied by using the tracer methods of both 137C3 and 60Co with Ge (Li) Gamma ray detector and S-80 type multichannel-analyser for measuring the radioactivity of the sample. The experiment was carried out in four groups and the period of the experiment was fifteen days. It was found that 60Co could be transferred along seawater→Platymonas→Brackionus→Tilapia, and that 137C3 could only be transferred from seawater to Platymonas. 137C3 was not accumulated by Brachionus in any group of the experiment. Brachionus ingested 60Co mainly from Platymonas, when 60Co was ingested by Tilapia; Brachionus played an important role in the transfer and the Tilapia ingested 137C3 mainly from seawater.
