PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1939 591 
sizes of bream taken from the ponds when they were drained, it is 
believed that this species spawned at least 9 months of the year in this 
locality. By enlarging the existing ponds, the water acreage was 
increased approximately 85 acres. All levees were regraded and 
seeded with Bermuda grass, and willows were planted to prevent ero- 
sion around embankments excépt where there was danger of the roots 
clogging drainage lines. 
Seventeen ponds covering 11.83 acres at the Marianna, (Fla.) unit 
were completed during the fall of 1938. On filling these ponds with 
water it was found that 6, due to seepage through the bottoms, would 
not hold sufficient water for the production of fish. Therefore, the 
output of 114,000 fry and 92,650 fingerling bass distributed from this 
station during the spring represents the production obtained from 
5.93 acres of water. Difficulty was also encountered in obtaining 
sufficient brood stock from local sources for properly stocking the 
ponds that were utilized. As there was an unusually heavy culture 
of daphnia in the ponds used, the fish showed a remarkable growth. 
At the close of the year preparations were being made to apply a 
waterproofing treatment to the bottoms of all ponds. All buildings 
were completed and the surrounding grounds landscaped. 
The Tupelo (Miss.) station, which has a pond area of only 16% 
acres, produced more than 850,000 bass and bream, of which all except 
198,000 were fingerlings. While the output of fingerling bass per 
acre was 42,500, the bream production was below 17,000. A six-room 
cottage was constructed. Approximately 8 inches of dirt was removed 
from four of the pond bottoms to eliminate the growth of water Lilies, 
which have hindered the production and collection of young fish. 
Inasmuch as several of the ponds at the Warm Springs (Ga.) 
station were not in operation, because of the fact that new supply and 
drainage lines were being laid and pond banks were being repaired 
and widened, the output of fish was slightly less than that of last year. 
Nevertheless, this unit produced approximately one-half million bass 
and bream for distribution. Catfish were received from the Lake Park 
unit and redistributed to applicants. In addition to the above con- 
struction activities, all buildings were repaired and painted. 
Although unfavorable weather conditions prevailed and the water 
in the ponds was turbid during the spawning season, the Mammoth 
Spring (Ark.) unit attained a new record in the production of small- 
mouth black bass, with an output of 237,000 fry and 150,000 finger- 
lings. In addition to this species, largemouth black bass, rock bass, 
and bluegill sunfish were handled. A five-room cottage was con- 
structed and repairs were made to all buildings, the barn being con- 
verted into a two-car garage. New concrete kettles were poured in 
three ponds and the levees and bottoms to all ponds were repaired 
and graded. 
The city of St. Louis, Mo., with the assistance of the W. P. A. and 
P. W. A., built at the Forest Park station a new stone structure con- 
sisting of living quarters, office, garage, workshop, and holding shed. 
Ten new lakes were built and several of the old lakes and lagoons 
were deepened, cleaned, and reconditioned. New outlets were con- 
structed and a better water supply system arranged to each lake and 
lagoon section. Due to these activities some of the lakes were not on 
a productive basis. Nevertheless, this unit produced approximately
