propagation of chinook salmon, the Big White Salmon station aug- 
mented its salmon work by handling brook and rainbow trout. New 
‘buildings were constructed at both points and numerous repairs 
made to old structures. 
The Quinault (Wash.) station collected its quota of sockeye salmon 
eggs for hatching, which is 2,000,000, and secured an additional 200,000 
for transfer to the Washington State Fisheries Department. This unit 
also handled chinook and silver salmon and steelhead, rainbow, brook, 
and blackspotted trout. The eggs for all species propagated, except 
the latter two, were collected locally. Approximately 3,350,000 eggs 
were handled and the resultant fish were all reared to fingerlings before 
being liberated. The Humptulips trap, which is located on the West 
Fork of Humptulips River, was completed and operated during the: 
chinook salmon and steelhead trout runs. Other construction work 
consisted of the followmg: Food room rebuilt, hatchery building 
reroofed, new office in hatchery constructed, large cold-storage room 
built, mew concrete walks and stairways poured, and grounds 
landscaped. 
The major fish-cultural activity at the Duckabush and Quilcene 
(Wash.) substations was the propagation of chum salmon. Due to 
stream-improvement work at the mouth of the Big Quilcene River at 
the height of the spawning season of the early run, the latter station 
was unable to secure any chum eggs from this source. However, the 
Duckabush unit collected 2,870,000 eggs from the early run in Ducka- 
bush River and both stations secured from the late run in the Walcott 
slough field more than 8,000,000 eggs. The spawned-out adults were 
transferred to the Quilcene dehydrating plant, and the dry salmon- 
meal was utilized at a number of trout hatcheries for fish food. The 
Quilcene hatchery supplemented its salmon work by concentrating 
on the production of trout fingerlings during the summer months for 
the stocking of local waters. At this station a new building was 
constructed and the necessary troughs and equipment were installed 
for conducting pathological studies. 
MARINE SPECIES 
The Boothbay Harbor (Maine) station collected 1,419,860,000 cod, 
517,305,000 pollock, and 417,832,000 haddock eggs which, after 
being fertilized, were liberated upon the natural spawning grounds 
of the respective species. From 670,000,000 flounder eggs incubated 
in the hatchery, a hatch of 90 percent was attained. The number of 
eggs of this species handled was in excess of last season’s by 76,000,000. 
In cooperation with the Sea and Shore Fisheries Commission of Maine, 
lobster culture was continued. Near the Bureau’s hatchery this 
agency constructed a rearing station that is equipped with 500 
lobster-rearing compartments. It is believed that when all details 
have been completed this unit will have facilities for rearing 1,000,000 
lobsters to the fourth larval stage. There were on hand at the begin- 
ning of the year 327,400 lobster fry from which a number of fourth- 
stage lobsters were raised and liberated at different points along the 
coast of Maine. During the spring of 1939, 3,915 adult egg-bearing 
lobsters were secured. Some of these adults were placed in cod boxes 
which had been rearranged in order that the young lobsters could
