PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1939 579 
3,000,000 fry were liberated in Minnesota waters. The collecting of 
pike perch eggs was carried on in cooperation with the United States 
Forest Service. From 21,500,000 eggs of this species collected, 
13,640,000 fry were distributed. Brook, rainbow, and brown trout 
eggs were hatched at this station for the stocking of local trout waters 
and for the Cascade rearing ponds in the Superior National Forest. 
The low temperature of the hatchery water supply induced high 
mortality among the trout eggs. Repairs and improvements were 
made to buildings and equipment by P. W. A. and W. P. A. workers. 
Because of the high water temperatures which existed at the 
normal spawning period, the whitefish spawning season on Lake Erie 
in the vicinity of the Put im Bay (Ohio) hatchery was unusually late. 
However, more than 48,200,000 whitefish eggs were collected and 
placed in the hatchery. On December 29 the water-supply line to 
the hatchery froze, necessitating the planting of all eggs in the lake. 
There were 943,340,000 pike perch eggs collected from the 6 fields 
‘worked—one of the largest collections in the history of this station. 
The most productive field was at Port Clinton, where more than 
500,000,000 eggs were secured. The propagation of both species was 
carried on in cooperation with the Ohio Conservation Division. 
Due to the shortage of funds, the Cape Vincent (N. Y.) station 
was unable to send spawn-takers into the field. Therefore, it was 
necessary to depend upon the local commercial fishermen for the 
supply of lake trout and whitefish eggs. There were 1,108,800 lake 
trout eggs handled, while 70,000 whitefish eggs of poor quality were 
received. The major activities are the propagation of game fish, 
particularly smallmouth black bass, and the operation of substations 
for the rearing of trout. This phase of the work is discussed else- 
where in this report. At the Swanton (Vt.) substation all buildings 
were reroofed and painted, but there were no fish-cultural activities 
carried on. This unit has, in previous years, handled pike perch 
and yellow perch. 
ANADROMOUS SPECIES, ATLANTIC COAST 
The Edenton (N. C.) hatchery surpassed its 1938 collection of shad 
eggs by taking 11,134,000 from which 7,134,000 fry were hatched. 
All of these fry were planted in Albemarle Sound and its tributaries, 
with the exception of 500,000 which were planted in hatchery ponds 
for investigation and study. A culture of daphnia was maintained 
in the ponds until the shad were seen swimming along the shoreline, 
at which time artificial food was given them. The food consisted 
largely of ground fresh fish and shrimp meal. A new field was located 
on the other side of the sound near Mackeys, from which 8,300,000 
white perch eggs were collected. A limited number of yellow-perch 
eggs were secured. The Edenton station propagates pondfish for 
the stocking of inland waters, supplementing its work with the 
commercial species. This unit was favored with W. P. A. and 
P. W. A. projects, which resulted in the completion of several ponds, a 
residence and other improvements. The Weldon (N. C.) substation 
was operated in cooperation with the Conservation Department of 
North Carolina for the hatching of striped bass, and 3,413,000 eggs of 
this species were collected. 
| The Orangeburg (S. C.) station operated an auxiliary hatchery on 
the Edisto River near Jacksonboro for the propagation of shad.
