until they were about 1% inches in length, when part of them were 
liberated to relieve overcrowding, and the others were fed until they 
reached a length of about 2 inches. The only major construction was 
the installation of a new water-supply line. 
The Quilcene (Wash.) station and the Walcott Slough egg-collecting 
unit operated normally. Chum-salmon and steelhead-trout spawn 
was collected from wild fish, and cutthroat-trout eggs from the station 
brood stock. Blackspotted-, brook-, and rainbow-trout eggs were 
received from other sources. The collection of chum-salmon eggs was 
below normal. This shortage is attributed to the fact that the 1936 
output of chum fingerlings was planted elsewhere than in the Walcott 
Slough. Satisfactory results were obtained with the use of apple 
flour as roughage in the food formula. Alder sawdust is now being 
tried in place of the apple pomace. Chum salmon were distributed as 
fry. The other species handled were held to relatively large fingerling 
size before they were liberated. The refrigeration plant under con- 
struction at the close of last year was completed, and meat grinding 
and refrigeration equipment was installed. All buildings were com- 
pletely wired for electricity. The N. Y. A. gave much helpful assist- 
ance. In addition to making fry trays and office furniture for various 
units in the region, the N. Y. A. shop at Port Townsend overhauled 
and repainted all trucks and other machinery in need of mechanical 
repairs. 
MARINE SPECIES 
The Boothbay Harbor (Maine) station began collecting pollock 
egos in the Portland section on November 1. The collections in- 
creased until the last of November and then declined until December 
15, at which date the take did not warrant the expense of further 
operations. During this period 1,060,000,000 eggs were taken, 
fertilized, and liberated on natural spawning grounds. This was an 
increase of 105 percent over the preceding year. In collecting cod 
eggs it has been the custom in past vears to place spawntakers aboard 
the larger commercial fishing boats during the spawning season to 
take ripe eggs from the catch. The Bureau’s boats collected the eggs 
on the fishing grounds, fertilized, and planted them on spawning beds. 
This year the commercial fishermen moved to more distant fishing 
erounds, thus curtailing the Bureau’s operations. Fishermen aboard 
the vessels were employed to take the eggs, fertilize, and plant them, 
and one of the Bureau’s spawntakers was at hand to check the take 
and plantings. The method was more economical than that used in 
the past, but it is questionable if the eggs were of the same high 
quality as in previous years. The cod egg-taking season began March 
22 and closed June 25. The total number of eggs collected was 
1,282,103,000, which was 90.3 percent of last year’s record. 
Haddock operations were carried on in conjunction with codfish 
activities. The commercial net fishermen were paid 5 cents per quart 
for eggs collected and planted. The first collections were made April 
4 and operations continued until June 4, during which period 253,582,- 
000 eggs were taken. Of the 681,000,000 flounder eggs secured and 
incubated in the hatchery, a 90 percent hatch was obtained. During 
June 1940, 7,532,000 lobster eggs were hatched naturally, of which 
4,842,000 were assigned to the State of Maine and 2,690,000 were
