XII REPORT TO THE SECRETARY OF COMMERCE 
FISHES OF INTERIOR WATERS 
Waters well stocked with sport fishes are an important asset to any 
community, attracting anglers, and thus bringing wealth into the 
community in many ways. Good trout streams are especially sought 
after. The bureau finds it necessary to obtain a large percentage of 
its brook-trout eggs from commercial producers, but most of the 
rainbow and other trout eggs have been secured from wild fish or 
trom hatchery brood stocks. The bureau’s collecting stations for 
rainbow eggs in the Meadow Creek (Mont.) territory and the Lost 
Creek and Sage Creek (Wyo.) fields were notably successful, while 
other smaller projects of a similar nature in the Rocky Mountain 
territory have been developed. The Meadow Creek field also yielded 
an increased number of Loch Leven trout eggs during the past year, 
this immigrant having become more firmly established in the esteem 
of the angling fraternity. A station for collecting rainbow eggs was 
established in New Hampshire during the past season under the 
supervision of the Nashua (N. H.) station. The White Sulphur 
Springs (W. Va.) station has a fine brood stock of rainbow trout, 
and the fish have yielded eggs of excellent quality. 
Statistics of the collection of black-spotted trout eggs in the Yel- 
lowstone National Park cover parts of two fiscal years. ‘The close of 
the spawning season brought a harvest of eggs surpassing that of the 
previous year, but not equal to the standard set during the early 
years of the operations. Glacier Park, as well as the Yellowstone, 
has received the attention of the bureau. 
The operation of the bureau’s pond stations, situated chiefly in 
the Southern States, has resulted in an output surpassing all previous 
records at several points, particularly at the Cold Spring (Ga.), 
Tupelo (Miss.), and San Marcos (Tex.) stations. The Louisville 
(Ky.) station is of especial interest in that it is particularly success- 
ful in the production of small-mouthed bass, a species unusually diffi- 
cult to raise in hatcheries. Some shght damage, not of a serious 
nature, was suffered at the Mammoth Spring (Ark.) station from 
spring floods. The superintendent of the Cold Spring (Ga.) sta- 
tion reported considerable success in feeding adult pond fish on 
shrimp heads, a waste product of a coastal fisheries. 
DISTRIBUTION OF FISH 
The carrying capacity of the fish-distribution cars has been in- 
creased greatly through the introduction of improved equipment, 
which has made it possible to handle the increased output of the 
hatcheries. During the fiscal year these cars traveled 63,300 miles, 
and detached messengers covered 363,565 miles. 
The construction of at least one more steel distribution car is abso- 
lutely necessary for handling the increased output of fish, as well as 
for economy and safety in making the distribution. The cars and 
messengers are now carrying twice as many fish in a single shipment 
as were carried 10 years ago, so that there is little opportunity for 
effecting further savings by larger shipments.
