592 U. S. BUREAU OF FISHERIES 
400,000 fingerling fish for distribution. This station has proved a 
very valuable addition to the Bureau, inasmuch as it furnishes fish 
for the stocking of waters which heretofore had to be supplied from 
some remote point. 
At the Tishomingo (Okla.) station approximately 14 acres of 
additional ponds were constructed. The following stone structures 
were built at this point: Four-room residence, three-stall garage, tool 
shed, and oil house. A holding shed is also under construction. 
Shortage of rainfall lowered Pennington Creek, the source of water 
supply, to where it was not flowing enough to maintain the proper 
level in the ponds. However, the 1939 output of fish was 716,980 
fingerlings. Efforts to propagate channel catfish were a failure. 
At the Natchitoches (La.) station W. P. A. and P. W. A. workers 
were engaged throughout the greater part of the year in the excavating 
of new ponds, laying of drainage and supply lines, buiiding of a fence, 
eravelling of roads, repairing old pond bottoms and embankments, 
and constructing outlet kettles. Nevertheless, the output of fingerling 
largemouth black bass, warmouth bass, and sunfish was in excess of 
the previous year’s record. 
In addition to distributing more than 1 million fingerling largemouth 
black bass, bluegill sunfish, Rio Grande perch, and channel catfish, 
the Uvalde (Tex.) station liberated approximately 400,000 bass fry 
in local waters. The 39 ponds, totalling 44 acres in area, were devoted 
to the propagation of game species of fish, and 12 ponds, about 
¥% acre each in area, for the handling of forage minnows. As the 
water at this hatchery contains certain chemicals, the steel water- 
supply lines were corroded to the point where it was necessary to 
replace them. At the end of the year approximately 85 percent of 
the lines had been replaced with composition pipe. An addition to 
the implement building was constructed and the exteriors of all 
station buildings were painted. 
The output of fry and fingerlings from the San Marcos (Tex.) unit 
approximated normal figures. Several old buildings were razed and 
a new combination garage, shop, and storage structure was built. 
A small building was also constructed for the purpose of storing paint, 
oil and grease, and other highly inflammable supplies. All old sta- 
tion buildings were repaired and painted. Considerable work was 
done on ponds, grounds, levees, and roads. 
From the brood stock of 4 species of fish handled at the San Angelo 
(Tex.) Station, more than \ million fingerling fish were distributed. 
Extensive daphnia culture was carried on during the spring months 
to produ :e food for the fry, and golden shiners were introduced in the 
rearing ponds when the bass were about 11!4 inches long. A residence 
and double garage were constructed during the vear. The pond 
system drainage line was completed. The exteriors of all buildings 
were painted, the grounds around the new buildings landscaped, and 
the station driveways were regraded. 
At the Fort Worth (Tex.) station the output of sunfish and war- 
mouth bass was in excess of that of last year, while there was a shght 
recession in the number of largemouth black bass, crappie, and cat- 
fish distributed. This station was enlarged by the acquisition of a 
site containing 31 acres, on which 10 ponds, covering approximately 
14 acres, were excavated. All old pond embankments were repaired
