PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1927 719 
Nasuvua (N. H.) Sration 
{J. D. DE RocueEr, Superintendent] 
Extensive improvements were made at this station during the year The 
old hatchery building was razed and a new building constructed. This has not 
yet been equipped completely, but it will be in condition for operation during 
the fiscal year 1928. Other buildings, including the carpenter shop, apprentice 
fish culturist’s cottage, and office, were moved and repaired. 
The station maintains a small brood stock of brook trout and rainbow trout. 
From these 116,500 and 193,000 eggs, respectively, were taken. A shipment of 
rainbow-trout eggs was received from the White Sulphur Springs (W. Va.) 
station, and a small collecting station at Lebanon, N. H., was developed, which 
yielded 122,000 eggs. The usual shipments of brook-trout eggs were received 
from commercial dealers, and over 500,000 fry of that species were distributed. 
A small number of landlocked salmon was hatched for distribution to applicants 
in that vicinity. The Loch Leven fingerlings on hand at the opening of the year 
were distributed. While this station operates no ponds for the warm-water 
species, 31,500 smallmouth bass were collected in Lake Sunapee, N. H., and a 
small number of catfish fingerlings was collected from near-by waters. It is 
the practice to hold a considerable number of fingerlings over the summer at 
this station, and at the close of the fiscal year there were on hand more than 
twice as many brook trout, rainbow trout, and landlocked salmon as was the 
case at the close of June, 1926. 
COMBINATION TROUT AND POND STATIONS 
While the five stations comprising this group are listed as combina- 
tion trout and pond stations, the bulk of their output is trout. Satis- 
factory increases have been noted in the output of trout, but the 
bass, crappie, and sunfish production at some of these stations has 
not been so successful. 
ERWIN (TENN.) STATION 
[A. G. KEESECKER, Superintendent] 
Considerable change in the pond system of the station was effected by con- 
structing new walls, extending-old ones, and rebuilding outlets. The supply canal 
was cleansed of two years’ accumulation of silt, and a water tank for a domestic 
supply was constructed. Considerable effort is required to keep the ground in 
an attractive condition. 
The output of fish was smaller than in the previous year, as 2,000 rainbow 
trout that should have spawned this year failed to produce any appreciable 
number of eggs. The actual collections amounted to 786,115, an increase over 
the previous year, but a low percentage of hatch cut down the output. Loch 
Leven and steelhead trout were incubated to meet some special requests for these 
species, and 20,000 brown-trout eggs purchased by a private party were hatched 
and delivered to him. A shipment of 20,000 rainbow eggs from wild fish was 
received, and the fingerlings are being reared to form a future brood stock. The 
station was unfortunate in receiving a poor quality of brook-trout eggs from 
commercial dealers, and this was partly responsible for a smaller output. The 
building of a State road through the station grounds was a contributing cause of 
an unsatisfactory year with the pond species. Cold and rainy weather kept the 
ponds constantly turbid from the wash of new earth from the highway work. 
Distribution of about 40,000 largemouth bass was made up to the first of the 
year, and the muddy water makes it impossible to say how many more black 
bass, rock bass, and sunfish remain in the ponds. Unless some provision is made 
to take care of surface drainage, it is likely that difficulty will be experienced in 
producing adequate numbers of these species for several years to come. 
MancuestTer (Lowa) STATION 
[G. H. Griz, Superintendent] 
Recovery from the effects of the flood of 1925 has been complete so far as the 
physical damages are concerned. Production has been brought almost up to 
normal, and over 1,000,000 eggs and fingerlings were shipped. Over 455,000 
eggs were obtained from the station brood stock. Two of the smaller earth
