HATCHERY FISH-CULTURAL NOTES 
NEW HATCHERIES 
Surveys have been made of possible sites for the new auxiliary of 
the Warm Springs (Ga.) station, and final investigations are now 
under way for the location of the hatchery. Preliminary arrange- 
ments have been completed for the establishment of a proposed 
auxiliary of the San Marcos (Tex.) station at Fort Worth, Tex., and 
actual construction work is now waiting on the clearing of the title 
to the property under consideration. 
ENTOMOSTRACA FOR PONDFISH 
The superintendent of the Wytheville (Va.) station received from 
the New Jersey State hatchery at Hackettstown, N. J., a stock of 
two species of daphnia. One form, Daphnia magna, attaims a very 
large size and is useful for that reason. The other, Daphnia moina, 
is a Japanese form and is unusually prolific. These organisms 
constitute the main food supply of young bass. The cultures trans- 
ferred to the Wytheville ponds flourished, and the superintendent 
reports a notable increase in growth in the fish receiving them. A 
stock has been shipped to the bureau’s Georgia and Tennessee 
stations and also to the State of Kentucky. 
NEW DIET FOR PONDFISH 
The superintendent of the Warm Springs (Ga.) station has been 
experimenting in feeding shrimp heads to the brood fish in the station 
ponds. This material is largely a waste product of the coastal 
fisheries. The fish appear to take it readily and thrive upon it, 
but it has not been used sufficiently long to determine fully its actual 
value as food for pondfish. 
COMMERCIAL FISHES 
Fishes of great commercial importance constituted a large part of 
the output for the past year. The hatching of Pacific salmons is 
supplementary to conservation by legal restriction. The propa- 
gation of whitefish, cisco, lake trout, and pike perch probably is 
one of the most important factors in the perpetuation of these fishes. 
The propagation of the marine species as well as the anadromous 
shad and herring of the Atlantic coast is responsible for the salvaging 
of eggs that otherwise would be lost in marketing. The culture of 
carp and buffalo fish also is directed toward the improvement of 
the economic fisheries. 
PACIFICESALMONS 
As the collection of eggs from these species is dependent upon the 
natural runs, considerable fluctuation in the numbers taken occurs 
from year to year. During the past year, however, smaller collections 
in some fields were offset by gains in others, so that the total take of all 
species aggregated 1,000,000 more than in 1926. Brook trout were 
hatched during the year at the Puget Sound (Wash.) stations and at 
ine Yes Bay (Alaska) station. A more detailed résumé of the work
