Abstract

The transfer of ¹³⁷Cs, ⁶⁰Co along Platymonas sp., Brachionus plieatilis Müller and Tilapia mossambica Peters was studied by using the tracer methods of both ¹³⁷Cs 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 ¹³⁷Cs could only be transferred from seawater to Platymonas. ¹³⁷Cs 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 ¹³⁷Cs mainly from seawater.
