fish for a few more weeks before liberating them.
It is not
felt that sufficient numbers of these fish are available to
attempt a second marking, liberation to migrate to sea, and
subsequent recovery program.
Such a program may be possible
and feasible to attempt after the main returns expected in
the fall of 1947 have been evaluated.
Sections III and IV.
The sockeye salmon data have not been written up as yet.
Section V.
The analysis of the preliminary steelhead trout experiment has not been completed.
Seotions VI, VII and VIII.
Final reports have been submitted on the basic experiment.
Asupplemental report is in progress, measuring the effect of
X~rays on the gonads of larval chinook salmon irradiated during
the eyed stage.
Counts are being made of the primordial germ
cedls and measurements of the diameters of the gonads are recorded.
Some attempt is being made to determine the volume of
the gonads.
The gonads appear to be the most sensitive to X-rays
of the organs in this group.
