perch, yellow perch, and striped bass. These are handled somewhat 
as a side line since they are propagated during the inactive season for 
shad. The output of 1,797,000 striped bass fry in North Carolina 
represents a material increase and is in line with an effort to build up 
this valuable species. 
Commercial species, interior waters.—Inasmuch as the supply of 
buffalofish and carp appears adequate for economic needs the hatch- 
ery production of these forms was curtailed and no carp whatever 
were distributed. Several of the States in the Great Lakes area are 
opposed to any promiscuous propagation or distribution of carp and 
the Bureau has coordinated its work accordingly. Asa consequence 
the present contribution to the commercial fisheries of the interior 
section was the propagation of whitefish, lake herring, and lake trout 
carried on at Put-in-Bay, Ohio; Duluth, Minn.; and Cape Vincent, 
N. Y. Production of pike perch at Put-in-Bay was brought up to 
334,000,000, a noticeable increase over 1938. The aggregate produc- 
tion of whitefish at the Bureau’s stations amounted to approximately 
33,000,000, somewhat lower than the previous year. Lake trout pro- 
duction at a level of slightly over 2,000,000 reflects the difficulty of 
securing eggs of this species. A new policy was adopted in connec- 
tion with the propagation of the lake trout, however, by the reopen- 
ing of the Bureau’s hatchery at Charlevoix, Mich., for the purpose 
of rearing the fish to the fingerling size before release. Several hun- 
dred thousand lake-trout fry were supplied by the Michigan Con- 
servation Department and were being fed at the Charlevoix hatchery 
at the close of the year. The activities at the Put-in-Bay, Ohio, 
station were conducted jointly with the State of Ohio, as has been the 
case for several years. It is felt that the State is in a position to take 
full responsibility for this work and at the close of the year negotia- 
tions were under way whereby the hatchery property might be turned 
over to the State. 
Gamé species——Again the collection of black-spotted trout eggs at 
Yellowstone Park was materially increased, the collection of eggs 
approaching 40,000,000. There was a moderate drop in the produc- 
tion of the other species of game trout, and a noticeable increase in 
the production of largemouth and smallmouth bass, the distribution 
amounting to over 14,000,000. Of this total, approximately 9,000,000 
represented the fingerling and larger sizes which are so eagerly sought 
for restocking the tremendous area in which these two species thrive. 
The yield of the lesser warm-water species, including the sunfish, 
crappie, rock bass, warmouth bass, catfish, etc., was greatly below 
the levels maintained previously. However, as indicated elsewhere, 
this is of little significance as far as stocking is concerned because 
of the fact that the millions released in previous years were largely 
replanted directly in the Mississippi River in the area where they 
were salvaged. There was a continuation of the program for acquir- 
ing more distribution trucks, and the handling of fish applications 
was systemized and organized so as to coordinate the planting with 
the corresponding activities of the States. More and more of the 
game fish from Federal hatcheries are being utilized in stocking Fed- 
eral lands, particularly in national forests, reclamation reserves, Indian 
reservations, and tracts which have been acquired in the land-utiliza- 
tion program.
