308 REPORT OF THE SECRETARY OF THE INTERIOR 
Bureau of Reclamation in and near Leavenworth, Wash., were not in 
full operation at the close of the year. It was expected, however, 
that part of the 1940 run of salmon would be handled at this plant. 
The existing salmon hatcheries located on the Rogue River, on 
Puget Sound, and at Quinault,-Wash., as well as on the two rivers 
mentioned above, produced an aggregate output somewhat less than 
the previous year. The greatest reduction was with the chinook 
salmon, the difference being 13,000,000. Fewer chum salmon were 
propagated. There was a slight increase in the output of silver 
salmon, with the production of the valuable sockeye species prac- 
tically unchanged. Nearly one-half million humpback salmon were 
provided, this being the year for the 2-year cyclic run of this species. 
The salmon hatcheries also propagated steelhead trout and were 
successful in doubling the output of this much-sought game fish. The 
hatchery at Little White Salmon, Wash., has been in process of recon- 
struction during the year, and minor improvements, mainly new ponds, 
were developed at several other points. Hatcheries at Mill Creek and 
Battle Creek, Calif., were inundated during the floods which visited 
the Sacramento Valley, but damage to property was negligible and 
loss of fish was slight. 
Anadromous species, Atlantic coast—¥or the second successive year 
the production of shad was increased, totaling 42,000,000 in com- 
parison with 34,000,000 during the previous year. The James and 
Chickahominy Rivers in Virginia were served by the pondfish station 
near Roxbury, Va., where previous attempts at shad culture had been 
largely unsuccessful. Experiments in the rearing of shad fry in 
ponds were continued, the results indicating that this practice may 
be a valuable supplement to present methods when suitable ponds are 
available. Yellow perch and white perch were also propagated at the 
shad stations on the Potomac River and Albemarle Sound. A pro- 
duction of almost 6,000,000 striped bass fry at the hatchery on the 
Roanoke River in North Carolina represents the highest level attained 
with this species in many years. 
Of outstanding interest is the resumption of the propagation of 
Atlantic salmon in Maine. After working out preliminary plans in 
cooperation with the Maine Department of Inland Fish and Game, the 
facilities of the East Orland Hatchery were improved. A few thou- 
sand salmon eggs were obtained from the Dennys River run in the 
fall. These were hatched and are being reared to fingerling size 
before planting. During the spring approximately 100 migrating 
salmon were taken from the fish ladder at Bangor, Maine, and trans- 
ferred to a holding pool prepared at the hatchery. Losses of injured 
fish were slight, and at the close of the year this relatively small stock 
of brood salmon was in good condition and prospects were favorable
