is supervising the Turtle Lake (Mich.) cooperative nursery and another one at 
Metamora, Mich. 
Alpena (Mich.) substation.—Whitefish-egg collections were carried on under 
the handicap of extremely stormy weather, with a consequent reduction in the 
number of eggs taken. Inability to secure experienced spawn takers was reflected 
in eggs of poorer quality. Further experiments at penning whitefish were made 
at Huron Beach, but with the same handicaps as were present in other fields. 
The possibilities of this practice are promising, however, and it should be con- 
tinued. Weather conditions were more favorable for lake-trout collections, and 
a normal yield was obtained. The eggs were of good quality, but losses through 
an accident cut down the percentage of hatch. 
A lake-trout nursery has been established at Rogers, Mich., and 300,000 fish 
are being reared. An equal number are being reared at the hatchery. A coop- 
erative brook-trout nursery in Wilson Township also is being conducted under 
the supervision of this station. In the spring pike-perch operations were con- 
ducted in cooperation with the State of Michigan. It was found that the use of 
muck to prevent adhesion gave better results than did starch. 
Charlevoix (Mich.) substation——The bad weather affecting the whitefish work 
at the above-mentioned stations was, of course, operative here. Its effect was 
noticeable chiefly in the quality of the eggs, as a larger number was obtained 
than in the preceding year. A period of bad weather prevents the lifting of the 
nets, and when the fish are removed they are in bad shape and the eggs are of 
poor quality. Greater cooperation on the part of the fishermen would go a 
long way toward perpetuating the whitefish by artificial propagation. The 
same general conditions have applied to the lake-trout work. An attempt was 
made to develop a collecting station for rainbow troui near the station, and a 
few eggs were taken. 
Put in Bay (Onto) STATION 
[Davip DaAvVIEs, Superintendent] 
The usual arrangements were made for opening the whitefish egg-collecting 
stations in the fall. The collection of whitefish eggs, however, was the smallest 
in several years. This, of course, was a reflection of the fact that unusually 
small catches were made by the commercial fishermen. There appears to have 
been a change in the habits of the fish, reduction of spawning on the grounds 
west of Put in Bay apparently having taken place. Fish are now spawning 
more plentifully in waters east of Kelleys Island. The season’s yield was 
122,800,000 eggs, of which over 79,000,000 hatched. 
In the pike-perch work there was a decrease of 50,000,000 eggs from the Port 
Clinton field, being offset largely by a gainin the Toledo field, so that the season’s 
take approximated that of last year. The spawning season was prolonged, and 
early breaking of the ice gave a longer fishing season. The percentage of hatch 
was rather low. Large collections of yellow-perch eggs were made, a number 
being shipped to Missouri and Montana and the remainder being incubated and 
planted in Ohio waters. The carp work at Port Clinton was only partly successful 
as the commercial catch of this species was very light. No satisfactory explana- 
tion for this condition is evident. Collections of smallmouth black bass were 
made in Lake Erie for brood stock for other stations. 
Carr VincENT (N. Y.) STATION AND SUBSTATION 
[J. P. SNYDER, Superintendent] 
Spawn takers were placed at four points on Lake Ontario during the lake- 
trout season. An innovation was attempted in the seining of lake trout to be 
held in pens to ripen. Difficulty in securing State permission for this work 
delayed its start, but a total of 600 fish penned, of which only 153 were females, 
gave 767,000 eggs. The yield for the season from all sources was more than double 
that of any previous year. A fair hatch resulted, and the majority of the young 
fish were returned to Lake Ontario. 
Adverse conditions confronted the whitefish work. Coupled with a failure 
to secure permission to take eggs from any but the most unproductive fields in 
Canadian waters, there were continual high winds that permitted the lifting of 
nets only four or five times during the spawning season. The largest number 
of eggs was obtained in the vicinity of Chaumont Bay. The adverse conditions 
prevailed during the lake-herring spawning season also. In spite of this, a
