During December the balance of the eggs produced from the adult salmon
returning to the Samish River, that in turn had been produced by adult
chinook salmon exposed to 100 r of X-ray prior to spawning, or that were
used as "controls", were transferred to the lboratory at the University of
Washington.
The majority of the eggs have now hatched and are in the
yolk sac stage.
The 38 irradiated- and control-stock chinookcsalmon adults retaken in
1947, produced 15 egg lots, the spawn from 13 of the females was apparently}e
mature and normal while the spawn from two females (Lot 13 and Lot 14)
appeared to be immature or "preen',

Further investigation into the inferior nature of the eggs in Lot 13
(100 r - 100 r X-rayed stock) with Lot 14 (control stock) revealed that
Lot 13 was from a "green't or slightly immature female, and consisted of
6059 poor eggs, deformed, including many of a pearshape.

In ordinary
Egg Lot 14 was also
from a "green" female resulting in a relatively small percentage of the
eggs flowing out into the bucket when the female was opened, but the 1386 eges
that were taken seemed at the time to be normal and would have been retained
in ordinary hatchery procedure.
