PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1927 717 
The station brood stock yielded 353,000 brook-trout, 152,000 rainbow-trout, 
and 230,000 Loch Leven-trout eggs. A good percentage of hatch was obtained. 
A shipment of 50,000 steelhead-trout eggs was received from the Pacific coast 
for incubation in local waters for the account of the State of South Dakota, with 
about 210,000 fingerlings of various species on hand. 
SPRINGVILLE (UTAn) Sration 
{CLAUDIUS WALLICH, Superintendent] 
The improvement of the concrete pond system by the installation of an indi- 
vidual drain and feed system for each of 20 ponds was reflected in a greater output 
of fingerlings. Operations at the field stations showed a gratifying increase in 
the collection of eggs from wild fish. 
A stock of 92,000 brook-trout fingerlings on hand at the beginning of the year 
was disposed of during the fall. The first brook-trout eggs were taken at the 
Fish Lake collecting station on October 29. In addition to generous shipments 
to the State hatcheries in accordance with agreements, 3,342,000 eggs of good 
quality were received at the station, 655,000 of which were hatched at Springville 
while the remainder was shipped to outside points. 
Rainbow eggs were derived from the station brood stock, which yielded 1,532,400, 
and from the collecting stations at Salem and Fish Lakes. The Salem Lake 
project is a small one, which it is hoped can be developed to produce a much 
larger number of eggs. The spring run of rainbows at Fish Lake yielded almost 
2,000,000 eggs in addition to those taken by the State. The percentage of hatch 
for both lots was somewhat higher than last year, but it was still somewhat 
below what might be expected. Successful shipments of rainbow eggs have been 
made from this station to Switzerland, Japan, and Hawaii. 
The only lot of native black-spotted trout handled consisted of 175,000 fry, 
which were on hand at the beginning of the year and were distributed at the close 
of the year. There were also on hand 883,000 fingerlings of the 1927 collection 
of rainbows. Cooperative relations of mutual benefit have been maintained with 
the States of Utah and Nevada, and these have been an important factor in 
placing the output on such a high level. 
nf NEW ENGLAND TROUT AND SALMON STATIONS 
The New Hampshire, Vermont, and Massachusetts stations are 
devoted to work with trout, and these species are an important part 
of the output of the Craig Brook (Me.) station also, which handles 
the commercial salmons as well. The scope and nature of the projects 
in this field are indicated by the extracts from the superintendents’ 
reports, cited below. 
HARTSVILLE (Mass.) STATION 
[E. P. THompson, Acting Superintendent] 
Operations at this station were more than ordinarily successful in 1927. A 
smaller number of eggs was obtained from the station brood stock of brook trout, 
but freedom from disease, which usually occasions heavy losses in the spring, 
resulted in an increased output of fry. The same can be said concerning trout 
eggs received from outside sources. Lake trout and rainbow trout were received 
from the Cape Vincent station, and a small number of these is being held over. 
Brook-trout fingerlings to the number of 89,405 are still being held for later 
distribution. In May the Cape Vincent station also furnished 60 adult small- 
mouth bass for breeding, but as yet no fry have appeared. 
Craic Brook (Mz.) STaTION AND SUBSTATIONS 
[GrorGe N. MonTGOMERY, Superintendent] 
Mention has been made previously regarding the Atlantic-salmon work at 
this point. Brook-trout eggs to the number of 1,483,618 were received at the 
station, of which 376,000 were taken from the station brood stock. The rest 
were secured by exchange or purchase from commercial dealers. These were of
