Cooperative Studies
Some of the experiments at the Laboratory are conducted
in cooperation with the Hanford Works, since the two facilities
working together provide much of the desired equipment, location
and experienced personnel necessary to the accomplishment of
these experiments.
Portions of the project are carried on in
one laboratory for a time and then continued by transferring
the animals to the other laboratory for further development.
Parts B. and C. of this section are projects of this type.

Temperature experiment with chinook salmon
The third and final phase of the temperature experiment

This phase of the work varied from what has been done previously
in that four instead of one race of salmon were used and in
that the temperatures changed with the season instead of remaining constant.
Observations are being made of mortality,

growth rate, and variation in meristic characters both within
and between racial groups.
