PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1939 585 
The hurricane which raged through the New England States on 
September 21 did little damage to the St. Johnsbury (Vt.) station 
other than blowing down some of the trees in the pine plantation. 
With the assistance of the W. P. A. and P. W. A. much valuable work 
was accomplished, not only in repairs to ponds, buildings, drainage 
lines, water supply, etc., but by the addition of several new raceways. 
A concrete intake dam in Sleepers River was constructed to replace an 
obsolete plank structure, thereby assuring a constant water supply at 
all times. As usual, the major fish-cultural activity was the hatching 
of approximately 134 million brook trout eggs. At the beginning of 
the year the entire stock of brown trout and landlocked salmon finger- 
lings was wiped out by the parasite ichthyophthirius multijilis. The 
fish-cultural work of this station is carried on in cooperation with the 
Fish and Game Service of Vermont. 
The Pittsford (Vt.) station continued its experiments in selective 
breeding of trout and conducted various other investigations. This 
year the adults yielded eggs at the rate of 1,424 per pound of fish. 
As the average fish-culturist recognizes 1,000 eggs per pound of trout 
as the normal production, the effect of selective breeding is obvious. 
This station was favored with W. P. A. and P. W. A. projects for the 
repairing and improving of buildings, equipment, and roadways. 
The Craig Brook (Maine) hatchery collected 4,300,000 brook trout 
eges, of which number approximately 2}; million were shipped to other 
Bureau stations. Shipments of rainbow and lake trout eggs were 
received, from which several thousand fingerlings were distributed. 
In accordance with an agreement between the National Park Service 
and the Bureau, the Acadia National Park was allotted 185,000 large 
fingerlmg brook trout for the stocking of waters under its control. 
Repairs and improvements were made to buildings, ponds, drainage 
and supply lines, roadways, etc., by P. W. A. and W. P. A. workers. 
In order to facilitate the repairing of old ponds and enlarging the 
pond system, the Hartsville (Mass.) hatchery disposed of its brood 
stock of trout. Consequently no eggs were taken at this pomt. 
Approximately 400,000 brook and 27,000 rainbow trout fingerlings, 
ranging in size from 1} to 4 inches, were distributed. In cooperation 
with the State of Connecticut, 773,000 smallmouth black bass fry 
were collected from Wangum Lake; one-half of which were assigned to 
the State of Connecticut. 
As the Nashua (N. H.) station was struck by a hurricane in Septem- 
ber, a large amount of time has been spent by the personnel in rehabili- 
tatingit. In addition to this work, a garage and 4 concrete ponds were 
constructed. This unit suffered high losses among all species of finger- 
lng and yearling trout the latter part of the year. 
COMBINATION TROUT AND PONDFISH STATIONS 
Although most of the establishments in this category have hereto- 
fore been primarily concerned with the propagation of trout, several 
of them have enlarged their facilities for the propagation of warm-water 
species. In some cases the production of spiny-rayed fishes is almost 
equal to the output of some of the smaller units which are exclusively 
engaged in the handling of pendfishes. 
At the Lamar (Pa.) station the hatchery building was completed 
during October and the necessary equipment placed therein, enabling
