Samples
waluat jon of Radioactivity in the Biological
Ssh
Almost 411 of the fish specimens, as in former years, were
,
llected by poisoning with derris root in shallow waters on or
J lear the reefs.
Some specimens were caught in the deeper
Maters of the lagoon with hook and line.
Two flying fish
Mere obtained outside the atoll when they landed aboard ship
luring the night.
The species selected for analysis are those commonly found
Gn the atolls and used for food.
They include damselfish,
oupers, parrot fish, squirrelfish, surgeonfish, goatfish,
@rasse, snappers, mullet and tune.
The scientific names of the
pecies are given in the appendix.
The tissues used for analysis of radioactivity were skin,
@muscle, bone, liver and other viscera.
The latter included part
Df the stomach contents as well as the alimentary canal,
in most
cases,
In an attempt to compare similar species from the same
locality, analysis was limited to the samples from Kabelle
msland.
Collesctions of fish were made in waters adjacent to
phis island on March 26, 1954, July 16, 1954, and January 29,
pI55.
The collecting area lies near the north end of the
pSland and consists of a coral-filled channel open to the sea
pt high tide.
The radioactivity of the tissues from the fish
Collected at Kabelle is Summarized in Figu
