PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1940 585 
In Utah the Springville unit distributed 1% million fingerling and 
adult fish. The take of rainbow-trout eggs was only about one-half 
the number collected last year, consequently fewer eyed egos were 
shipped to other stations. Approximately 1 million rainbow-trout 
eges were incubated. In addition brook. Loch Leven, and_ black- 
spotted trout were hatched and distributed. Between 45 and 50 
percent of the trout produced were allotted to national forests and 
national parks. The limited area of the ponds restricted the produc- 
tion of warm-water fish to 2 species, largemouth black bass and sun- 
fish, and 9,542 fingerlings were harvested per acre during the fall of 
1940. Twenty new troughs, which were constructed last year, were 
installed in the hatchery. ; 
The substation at Bear Lake, Utah, propagated four species of trout 
and more than 1 million fingerlings were distributed. Blackspotted- 
and rainbow-trout eggs were collected from wild fish trapped in tribu- 
taries to Bear Lake. Since only one trap was operated this spring, 
the take of eggs was considerably less than last year. Lake- and brook- 
trout eggs were received by transfer, and the fingerling chum salmon 
which were carried over from last year were planted in the Hyrum and 
Pineview reservoirs. 
Because of unfavorable conditions at the former Glacier Park unit, 
the National Park Service secured a new site near Creston, Mont. 
The equipment was moved to the new Glacier National Park Station 
and temporarily installed to enable production of fish to continue 
while the hatchery buildmg and ponds were being constructed. All 
brook and rainbow trout hatched were held as a nucleus for future’ 
brood stock. The Bureau assumed complete charge of construction 
on December 1, 1939, and the work was prosecuted, under a P. W. A. 
grant, with W. P. A. labor. At the close of the fiscal year the cottage, 
utility building, hatchery building, and water-supply system were 
completed. The landscaping, fencing, and other minor projects, are 
only partially complete. In addition to the 24.5-acre brood-stock 
pond, 23 rearing ponds were completed and 6 are in use. It is planned 
to propagate blackspotted, brook, and rainbow trout, and grayling, 
when this station reaches full production. 
Owing to an outbreak of furunculosis, all the brook trout at the 
Saratoga (Wyo.) station were disposed of. The water supply was 
treated with chlorine, followed by derris root, and there has been no 
evidence of the return of this disease. More than 3 million black- 
spotted-, brook-, Loch Leven, and rainbow-trout eggs were incubated. 
Four new concrete ponds 60 by 6 feet were built, posts were set, and 
wires were strung to keep out predatory birds. Remodeling of the 
superintendent’s house was about 50 percent completed. 
The Jackson (Wyo.) station was operated during the entire year. 
Blackspotted, brook, and lake trout were propagated. Since no brood 
stock are kept, and no wild eggs are collected, all eggs are received by 
transfer from other Federal and State hatcheries. The fish were dis- 
tributed by the National Park Service and the Forest Service in the 
waters of the Grand Teton National Park, and the Teton National 
Forest. More than 1 million fish were distributed, and approximately 
one-half million fish were on hand on June 30, 1940. The C. C. C. 
maintained a camp at that station until December 18, 1939, under the 
direct supervision of the Forest Service. The personnel of the camp 
was engaged in various activities such as landscaping grounds, grading
