102 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
died inside of ten days, and only 81,500 fry were produced, which were 
liberated on May 10 in Lake Erie. Lake trout have been but rarely 
observed in thé vicinity of the station during the past twenty years, 
none having been seen in five or six years by persons familiar with the 
locality. On November 7, however, Mr. E. J. Dodge took from one of 
his trap nets a specimen weighing nearly a pound, and on November 19 
he captured another, both being forwarded to the general office for 
identification. It is believed that the fish were of the 190,000 liberated 
from this station in the spring of 1890. 
Rainbow trout.—On February 14 and 18 consignments of rainbow- 
trout eggs, aggregating 75,000, were received from Neosho Station, 
Missouri. They were in excellent condition on arrival, but underwent 
considerable loss both in the egg stage and as fry, the young available 
for distribution numbering 65,000. The fry, on arriving at the feeding 
stage, were liberated in the vicinity, in Lake Erie. Owing to lack of 
vitality it is feared that only a portion survived. 
Pike perch.—Collections of pike-perch eggs aggregated 50,750,000, of — 
which 25,564,500 were obtained from the shoals of Put-in Bay and the | 
remainder from East Sister Island, Lake Erie, the season terminating 
April 19. The fry resulting numbered 20,200,000, of which 16,600,000 
were delivered by the steam launch Shearwater at Sandusky, car No. 1 
receiving 10,500,000, and car No. 2, 6,100,000. The remaining 3,600,000 
were put in Lake Erie. The cost of pike-perch eggs, all items included, 
is found to be about $1 per million. 
The distribution, exclusive of whitefish eggs, was as follows: Rainbow 
trout, 65,000; lake trout, 81,500; cisco, 6,595,000; whitefish, 22,570,000 ; 
pike perch, 20,200,000. 
Important aid was rendered in World’s Fair collections, the work 
being taken up March 29, terminating June 3. During that period four 
car loads containing 1,000 specimens, representing over forty species, 
were delivered for transportation to Chicago. Among these were 44 
adult brook trout from the Castalia Trout Club, presented by Hon. John 
C. Zollinger, president of the club, and delivered to our cars at San- 
dusky. Mr. Zollinger also presented 2,000 trout eggs from the hatchery 
of the club, but these, owing to defective packing, perished en route. 
An interesting development emanating from this station in connec- 
tion with the World’s Fair was the preserving of discarded fish eggs in 
brine for use in Chicago as representatives of good eggs in process of 
hatching. In 1890 Mr. Stranahan conceived the idea of illustrating 
hatching methods during summer, when active operations were sus- 
pended. Having succeeded fairly with his first trial, he concluded that 
something of the same character might be done at Chicago, and after 
experimenting he found that eggs could be successfully preserved in a 
brine sufficiently weak to permit their sinking slowly. The result of 
his observation and experiment proved highly gratifying in the fish- 
culture exhibit.
