from the disease known as “bluesac.” In each case, however, after 
culling out the defective stock no further trouble was experienced, 
and the distributions of young fish from the three lots of eggs com- 
prised 296,825 healthy No. 1 and 2 fingerlings, with 34,000 fingerlings 
on hand at the close of the year. 
From two lots of rainbow-trout eggs—one of 50,000 transferred 
from the White Sulphur Springs hatchery and another of 6,920 taken 
from the station fish—43,900 thrifty fingerlings were produced, of 
which 2,000 remained on hand at the end of the year. The spawning 
season of the rainbow trout at this station extended from December 
22 to January 20. 
CRAIG BROOK (ME.) STATION. 
[J. D. Dm RocHer, Superintendent. ] 
In addition to the propagation of the Atlantic salmon, for which 
purpose this station was primarily established, it has an annual out- 
put of brook trout from eggs purchased of commercial fish-culturists. 
The distribution of this species for the fiscal year 1921 amounted to 
1,085,000 fry and 23,625 fingerling fish. The year’s distributions also 
included landlocked salmon fry and fingerlings to the number of 
43,545, these fish being the product of eggs transferred from Grand 
Lake Stream. A detailed account of the work with the Atlantic 
salmon is contained in the section devoted to the anadromous fishes, 
page 45. 
Having an abundant water supply of excellent quality, this station 
possesses opportunities for development as a trout-rearing center. 
At comparatively small cost its capacity may be increased to the 
point where it will alone adequately meet the requirements of that 
section of the country. 
GREEN LAKE (ME.) STATION AND SUBSTATION. 
[JoHN A. Story, Superintendent. ] 
Perhaps the most important part of the work of this station is the 
propagation of the landlocked salmon. Operations addressed to this 
species are conducted at the main station, a substation at Grand Lake 
Stream, and an egg-collecting station on Fish River Lakes, the work 
at the latter point being done on a cooperative basis with the Maine 
Commission of Inland Fisheries and Game. At Fish River Lakes 
egg collections were made from Cross, Eagle, and Square Lakes 
Thoroughfares, aggregating 525,000. These were all delivered at the 
State hatchery for eyeing. Under the agreement 250,000 of them 
were reserved for planting in parent waters, while the remainder 
were divided equally between the bureau and the State hatcheries 
after being eyed. The lakes were at high level prior to the spawning 
season, with but little rain during that period. Under these con- 
ditions there was but little and a constantly decreasing current over 
the usual spawning areas. This is thought to have been a factor in 
the reduced egg collections, though whether or not it was the most 
important one it is hardly possible to say. A total of 336 male 
and 260 female fish were handled during the season, the first being 
taken on October 24 and the last on November 9,
