482 U. S. BUREAU OF FISHERIES 
extended its lobster-cultural work, collecting 1,200,000 eggs, which 
left some 1,000,000 fry on hand at the close of the year. 
While the Boothbay Harbor, Maine, station reported favorable 
weather conditions, a shortage of flounders on the regular spawning 
grounds curtailed production of this species to slightly more than 
730 million fry. An unusual development of slime on the spawning 
erounds is considered to have some bearing on the absence of breeding 
fish. Special effort in the spring yielded collections of cod eggs 
numbering slightly less than in the previous year. A moderate 
number of haddock and pollock eggs was also obtained. Here, too, 
in cooperation with the State of Maine, lobster culture was resumed. 
Three and one-fourth million fry were hatched. A new method of 
rearing with artificial feeding, as developed in Connecticut, was tried 
out on a portion of the fry, the balance being liberated. 
GREAT LAKES SPECIES 
The propagation of commercial species of the Great Lakes has 
continued at a relatively low level except on Lake Erie. Here the 
Federal hatchery at Put-in-Bay has been operated on a joint basis 
with the State of Ohio. One hundred and thirty-four million white- 
fish eggs and 451 million pike-perch eggs were handled in this work, 
with the hatch averaging at normal proportions. 
Since there is no special open season for egg-taking operations in 
Michigan waters, the Duluth, Minn., station secured only a few 
hundred thousand lake trout eggs, and 3% million whitefish eggs. 
Ten million pike-perch eggs were allotted by the State of Minnesota. 
The Cape Vincent, N. Y., station was unable to send spawntakers 
into the field due to shortage of funds, but secured whitefish, lake 
trout and lake herring eggs from local fishermen The total secured 
by this means approximated 2% millions. Some yellow perch and 
pike-perch fry were obtained from operations at the Swanton, Vt., 
substation which was maintained by the State of Vermont. 
As the work with commercial species at these stations has been 
curtailed, the slack has been taken up by extending the propagation 
of game fish. At Cape Vincent in particular the propagation of 
smallmouth bass has been quite successful and a number of trout 
rearing substations are operated in this field. 
ANADROMOUS SPECIES, ATLANTIC COAST 
Propagation of Atlantic salmon has been virtually discontinued 
because of inability to secure eggs from Canada. No supply is avail- 
able from domestic sources. The Craig Brook, Maine, station dis- 
tributed a few fingerlings, which had been held over from the previous 
year. 
The 11% million shad fry produced at the Fort Belvoir, Va., station 
represent a moderate increase over the previous year. "This station 
also supplemented its work with shad by hatching yellow perch, of 
which 237 million fry were produced. 
At the Edenton, N. C., station vigorous efforts were made to ex- 
tend the shad propagation activities. In cooperation with the State 
an employee of the Bureau was assigned to make a study of all factors 
concerned with the conservation of this species. A small run of shad 
defeated efforts to bring in eggs from distant points but collections 
from the vicinity of the station yielded 7% million eggs, an increase
