102 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



died inside of teu 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 th« 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 traji nets a specimen weighing nearly a pound, and on November 10 

 he captured another, both being forwarded to the general office for 

 identification. It is believed that the fish were of the 190,000 libei-ated 

 from this station in the spring of 1890. 



Bainhotc trout. — On February 14 and IS consignmonts 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 30,750,000, 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 i)ut in Lake Erie. The cost of pike-perch eggs, all items included, 

 is found to be about $1 i)er million. 



The distribution, exclusive of whiteftsh eggs, was as follows : Rainbow 

 trout, 65,000; lake trout, 81,500; cisco, 6,505,000; 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, ])resident of the club, and delivered to our cars at San- 

 dusky. Mr. Zollinger also in^esented 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 in^eserving of discarded fish eggs in 

 brine for use in Ciiicago 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 sufiiciently weak to permit their sinking slowly. The result of 

 his observation and experiment proved highly gratifying in the fish- 

 culture exhibit.
