BUREAU OF FISHERIES Ix 
As an indication of the relative proportions of the various classes 
of fishes of this total, it may be pointed out that it included 5,473,- 
378,000 fry and eggs of commercial marine species, 120,213,000 of 
the commercially important Pacific salmons, 548,535,000 of the com- 
mercial species of interior waters, and 247,313,000 of the anadromous 
forms, also of commercial significance. The game fishes were repre- 
sented by 51,523,000 trout and salmon and 36,222,000 of the warm- 
water pond species. 
RELATIONS WITH STATES AND FOREIGN GOVERNMENTS 
Cooperation with the various States has been an important part 
of the bureau’s fish-cultural work. The bureau has been of assist- 
ance by furnishing the advice and supervision of its experienced 
employees, by assigning eggs and fry to the States, and by assisting 
in the collection of eggs. The States have reciprocated by permit- 
ting the collection of adult brood fish, allotting funds for carrying 
on work of joint benefit, and by assisting in the distribution of fish. 
The Bureau of Fisheries and the States of Vermont and Pennsy]l- 
vania operated the Swanton (Vt.) pike-perch station jointly. Over 
1,000,000 trout eggs were incubated for the State of West Virginia 
at the White Sulphur Springs (W. Va.) station. Similar relations 
have been maintained with the State of South Dakota. The propa- 
gation of buffalo fish in conjunction with the State of Louisiana 
was undertaken. ‘The bureau furnished the services of a man for 
shad propagation undertaken by the State of New Jersey. Exten- 
sive cooperative work has been initiated in Arkansas, where suitable 
areas have been taken over as nurseries for bass and other pond fish. 
Ponds have been stocked, and a number of others are being prepared 
for this purpose. 
A total of 84,586,000 eggs was furnished to 24 States during 1927 
The pike perch, yellow perch, whitefish, and cisco comprised 
61,900,000 of this number, while the remainder consisted of various 
species of trout and salmon. 
Arrangements have been perfected with the United States Forest 
Service whereby improved distribution practices will be followed and 
rearing ponds established. Generous allotments of fish and eggs 
have been made for stocking waters in the forest areas, notably in 
Wyoming and in the Sawtooth National Forest in Idaho. Inspec- 
tions have been made of pond sites in the Ouachita National Forest 
and the Unaka National Forest. 
Requests for the shipment of eggs of various species to foreign 
governments have been complied with as far as possible: This in- 
cluded the distribution of 2,227,000 eggs and 19,500 fish to five coun- 
tries, Canada, Costa Rica, Italy, and Switzerland receiving rainbow 
trout, while Japan was assigned rainbow trout and whitefish. 
PROPAGATION OF PACIFIC SALMONS 
The work in the Pacific States and Alaska has been marked by im- 
provements at certain points. It has been the rule to hold a maxi- 
mum number of fingerlings at each station throughout the season, 
planting when for lack of space it has been absolutely essential to 
dispose of some of the stock.
