-3the major attention of the Staff during the month.
The adult
fish, the progeny of irradiated or "control" parents, continue
to spawn.
We have 270 egg lots to date, with a few remaining
to spawn.
This group now contains about a quarter of a million
eggs and young fish.
The eggs have been removed from the females, fertilized, and
each egg lot produced by a female kept intact during incubation
and absorption of the yolk sac.
It has been necessary to group
lots of similar irradiation ancestry after the yolk sac stage
has been completed and the fish reach the feeding stage.
The great numbers of young fish produced by this project
makes it impossible to retain them all in the laboratory, so
only portions of each lot will be retained as a sample of each
group.
Section XiIc.
The data in this section, pertaining to the second spawning after irradiation, will be summarized as soon as these data
from Sections XI and XIa are analyzed.
Sections XII, XIII and XIV.
Work on the final report is nearing completion.
Sections 43V - XVII.

The adult fish that were expected from the sea this spring
in this portion of the project, may not have been able to ascend
the Wenatchee River because of low water and the diversion of
much of the river for power development.
Section XVIII.
The goldfish studies have not been completed.

The studies on absorption and retention of radioactive ma-
terials have been continued.
