PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1927 723 
LovutsvILtLE (Ky.) STratrion 
[CHARLES W. BURNHAM, Superintendent] 
During the year the station grounds were improved by the erection of an 
ornamental steel fence along the public highway. 
At this station emphasis is placed upon the production of smallmouth bass, 
and gratifying results have been achieved. <A brood stock of 480 adults, divided 
among 4 ponds, produced over 500,000 fry and fingerlings. It has been found 
that much better results are achieved when the adult fish have been kept at the 
station a year and have become acclimated. The stock was partly renewed by 
a shipment of adults from Lake Erie, but considerable loss was experienced and 
the production of fry was limited from this lot of fish. The majority of the out- 
put is shipped as fry, and these are placed directly in the cans without ‘“‘hard- 
ening”’ in running water, as is usually the case. A small brood stock of large- 
mouth bass produced 5,100 fingerlings for distribution. A few rock bass and 
bream also were produced. 
As has been the practice in previous years, a shipment of 15,000 lake-trout 
eggs from the Duluth station was incubated at Louisville. The fry produced 
from this lot were turned over to the Kentucky Fish and Game Commission for 
planting in Kentucky waters. 
MaAMMoTH SPRING (ARK.) STATION 
[DELL Brown, Superintendent] 
In addition to enlarging and deepening several of the ponds, a shed was con- 
structed over the concrete retaining tanks. The station was visited by a flood 
on April 20, and the overflowing of the ponds caused a mixing of the species 
and a considerable loss of fish. Twenty early nests of smallmouth bass as well 
as 50 adults were lost by this means, but spawning was active later, and 45 nests 
produced 133,750 fingerlings for shipment. Similar conditions prevailed with 
the largemouth bass, 30 early nests of eggs and fry being lost through the flood. 
Later recovery was satisfactory, however, and shipment was made of 106,670 
fingerlings, while 10,000 or 15,000 were carried over. The stock of adult breeders 
on hand is in excellent shape, and with an opportunity to clean and dry the ponds 
each season it is believed that production can be increased materially. 
The shipment of rock bass in the fall of 1926 contained 18,500 good-sized 
fingerlings. Only one pond, containing 125 adults, is utilized for this species. 
The bream, also distributed during the fall months, gave gratifying results, with 
a production of 44,600 fingerlings from 165 adults. Apparently the hatch of 
the present season has been up to normal, and a satisfactory output is expected. 
Although handicapped by a flood, as stated above, the year as a whole was the 
most successful in the history of the station, 303,520 fingerlings having been 
distributed. Fifty thousand rainbow-trout eggs were shipped to the station in 
January. A 95 per cent hatch was secured, and the fry were planted at various 
times in Spring River. Previous plants of rainbows in this river have borne 
results, and good fish are taken frequently. 
ORANGEBURG (S. C.) STATION 
[G. W. N. Brown, Superintendent] 
The small number of bass produced at this station in 1927 is believed to have 
been due in some measure to the excessive number of old brood fish that were 
past their reproductive prime. Many were replaced in the fall by purchase of 
young stock. Of the season’s production of approximately 260,000 fingerlings, 
3,825 were of the previous season’s hatch and 1,800 were purchased. 
The discarding of aged and worthless brook stock among the bream was 
effective in increasing the output of this species. Distributions to applicants 
accounted for 31,475. Attempts at producing warmouth bass, crappie, and 
catfish were largely unsuccessful. Certain improvements, particularly the con- 
struction of a canal, will be necessary to utilize to the fullest advantage the 
available water area of the station.
