580 U. S. BUREAU OF FISHERIES 
There were 1,876,000 eggs collected, from which 1,534,000 fry were 
liberated in the Edisto and Ashepoo Rivers. While this number does 
not equal the records of previous seasons, it does represent an increase 
of one-half million fry over last year. 
At the Fort Belvoir (Va.) hatchery, located on the Potomac River, 
the main fish-cultural activities were the collecting and hatching of 
shad and yellow-perch eggs. The collection of shad eggs exceeded 
that of last season by more than 10 million, while there was a slight 
recession in the number of yellow-perch eggs secured. A one and one- 
half story, five-room, brick-veneer residence was constructed, and the 
marine railway and carriages were rebuilt. 
GAME-FISH PROPAGATION 
One would consider practically the entire output of the Bureau’s 
hatcheries as coming within this category, since all species propa- 
gated, except lobster, whitefish, herring and shad, are at some time or 
place sought by sportsmen. 
Never in the history of the Bureau have the demands been so great 
for game fish. This may be ascribed in part to the large number of 
reservoirs constructed by the Department of Agriculture i in its soil- 
conservation program, the impounding of large bodies of water by 
hydro-electric projects, the flooding of areas by the Bureau of Bio- 
logical Survey to create migratory bird refugees, and to the prosecut- 
ing of stocking programs formulated by various Federal and State 
agencies. However, the innate popularity of angling among all 
classes is probably the most comprehensive explanation for the demand. 
The following data cover the activities of the stations handling the 
families Centrarchidae and Cichlidae and the species of the Salmonidae 
found largely in inland waters. 
ROCKY MOUNTAIN TERRITORY 
Due to adverse weather during the spawning season, and water 
shortage throughout the summer, the output of pondfish from the 
Dexter (N. Mex.) station was below normal. Approximately 121,000 
of the fish distributed ranged from 5 inches in length to legal size. 
In cooperation with the New Mexico Department of Game and Fish, a 
stocking program was formulated for the waters of that State. This 
program was adhered to as much as possible, although a portion of 
Dexter’s production was utilized for the stocking of Arizona, Colorado, 
and Texas waters. Heretofore, predatory birds have devoured large 
numbers of this unit’s brood stock each winter and a network of wires 
was attached to cables over some of the ponds in order to frighten such 
visitors. A concrete cistern of 30,000 gallons capacity, for storing 
water for domestic use, was constructed. The metal fish tanks were 
removed from the holding house and replaced with 14 concrete tanks. 
All station buildings were repaired and painted and a large cactus 
garden was planted near the entrance to the station. 
The output of fish from the Santa Rosa (N. Mex.) substation was 
practically the same as that of the previous season. A number of 
choice smallmouth black bass fingerlings were saved out of last year’s 
hatch, and it is anticipated that the 1940 output of this species will 
be greatly increased. The number of food organisms produced in _ 
the ponds appeared to justify the expense involved in fertilizing them
