Propagation and Distribution of Food Fishes. 
HE work of increasing the supply of food and game | 
fishes by artificial means has become of more impor- 
tance each year, and there are now maintained by the gov- 
ernment 33 specially constructed hatcheries and 16 sub- 
hatcheries, located in 26 states and territories. Of the main 
hatcheries, 3 are on the New England coast, 8 are on the 
rivers of the Atlantic and Pacific seaboards, 4 are on the 
Great Lakes, and 18 are on the interior fresh waters. 
About 50 species are regularly propagated and distributed 
by the Bureau, and others are from time to time taken up 
as circumstances require or permit. Among the most im- 
portant species handled are the cod, pollock, flounder, and 
lobster among marine forms; the shad, salmon, striped bass, 
white perch, yellow perch, Atlantic salmon, chinook salmon, 
and blue back salmon on the coast rivers; the whitefish, lake 
herring, lake trout, and pike perch on the Great Lakes; and 
the brook trout, rainbow trout, black-spotted trout, land- 
locked salmon, grayling, black bass, rock bass, crappy, and 
catfish in the interior waters. 
One of the most interesting and important lines of work | 
is the introduction of foreign fishes into American waters 
and the transplanting of native fishes from one section of 
the country to another. A most noteworthy example of 
the successful transfer of native fishes to new waters was the 
acclimatization of the shad and the striped bass on the Pa- 
cific coast between 30 and 35 years ago; the aggregate cost 
of this experiment was less than $5,000, while the catch of 
these two fishes on the west coast to the end of 1906 ex- 
ceeded 30,000,000 pounds, valued at more than $1,000,000. 
Experiments are now in progress having for their object the 
colonizing of the Atlantic lobster on the Pacific coast and 
the establishment of the Pacific salmons in the waters of 
the Middle and New England States. 
Plants of fish are made gratis in suitable public or private 
waters, on the receipt of applications endorsed by a United 
States Senator or Representative or by a state fish commis-
