Evaluation ofRadioactivity in the Biological Samples
Pish
Almost all of the fish specimens, as in former years, were
collected by poisoning with derris root in shallow waters on or
near the reefs.
Some specimens were caught in the deeper
waters cf the lagoon with hook and line.

The tissues used for analysis of radioactivity were skin,
muscle, bone, liver and other viscera.
The latter included part
of the stomach contents as well as the alimentary canal, in most

Fa et aa
In an attempt to compare similar species from the same
locality, analysis was limited to the samples from Kabelle
Island.
Collections of fish were made in waters adjacent to
this tgsland on March 26, 1954, July 16, 1954, and January 29,
1955.
The collecting area lies near the north end of the
{sland and consists of a coral-filled channel open to the sea
at high tide.
The radioactivity of the tissues from the fish
collected at Kabelle is summarized in Figure 3.
