PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1927 687 
COOPERATION WITH STATES, OTHER FEDERAL AGENCIES, AND 
FOREIGN GOVERNMENTS 
Much duplication of effort was avoided during 1927, and great 
benefit resulted from a thorough cooperation with every State that 
interested itself in the conservation of its fisheries. Hatcheries were 
conducted jointly with Pennsylvania, Louisiana, and Florida, and 
eggs were incubated for the States of West Virginia, Missouri, North 
Carolina, South Dakota, and Washington. A list of the eggs assigned 
to the various States is given later in thisreport. The incubation and 
distribution of these eggs resulted in a marked saving to the bureau. 
In addition to such interchanges, the bureau gave advice and in 
some cases furnished the services of its experienced employees to solve 
fisheries problems affecting the States. The bureau’s program was 
aided materially by the permission granted by some of the States to 
collect brood fish in their waters. Ohio, New York, and Maine were 
particularly accommodating in this respect. 
Connections with the Forest Service of the Department of Agricul- 
ture have been mutually beneficial. This agency is interested in 
keeping the streams of the forest reserves well stocked and has 
distributed all fish that could be supplied for such waters. Many 
barren lakes in the West have been placed on a productive basis in 
this way. The Forest Service is now taking steps to rear fish and 
is providing sites for bass and trout hatcheries. Such sites have 
been inspected in the Unaka and Ouachita National Forests in 
Arkansas. 
The continued operation of the Yellowstone and Glacier Park 
hatcheries is evidence of the maintenance of former cooperative rela- 
tions with the park service. 
Wherever possible, the bureau has acceded to the requests of foreign 
governments for American species of fish. A list of such shipments 
made during the past fiscal year appears later in this report. 
FISH NURSERIES 
During the fiscal year 55 cooperative nurseries in 12 States were 
operated for the production of fingerling fish. Pennsylvania leads 
in such work with 15 establishments. The nurseries range in size 
from single units having a capacity of several hundred thousand 
(such as the one at Barneveld, N. Y., which really constitutes a sub- 
station of the Cape Vincent (N. Y.) station) to small plants capable 
of holding only 10,000 or 15,000 fish. The bureau furnished approx- 
imately 2,500,000 fish to these nurseries during the year. The fish 
are to be fed and cared for by the nursery owners and will be released 
when from 6 to 18 months of age. The bureau reserves the right to 
claim half of the output for filling applications for fish received from 
persons living in the vicinity of the nurseries, and the rest belong 
to the nurserymen for disposal in waters in which they may be 
interested. 
At present seven projects are being actively developed to receive 
fish at a later date; a number sufficient to bring the total to about 
75 are under consideration; and from the requests for future inspec- 
tions that are being received there is every indication that next year 
will see 100 or more of these private cooperative fish nurseries in 
operation. Basing estimates on the rearing capacity of the average
