at the station, 104,500 were shipped to Central Station for foreign ship- 

 ments, and 80,040 died during incubation. From the native rainbow 

 trout 10,000 eggs were shipped to the station from Hoopa Valley, 

 California, on March 24, and arrived at Wytheville April 2; but as all 

 the eggs hatched en route the shipment was a total loss. 



From 135 black- spotted trout at the station there were collected 

 12,000 eggs, but owing to the lack of milt only 500 were saved. The 

 propagation of this species has been tried at the station the past two 

 seasons, but without success. The sexes do not mature together, the 

 male having passed out of season when the female comes in. 



About November 5 the rainbow trout commenced to spawn and 

 ceased about February 20. Many of the older rainbows did not spawn 

 this season from some unknown cause. The brood stock of rainbows 

 consists of 5,400 fish, of whicli 1,000 are from 6 to 12 years old; 3,200 

 are 2 years old, and 1,200 are 1 year old. Very few of the 2-year fish 

 produced eggs this season. Of rainbows, there were distributed this 

 year 00,320 yearlings, 320 adults, and 15,000 fmgerlings. Fish of a 

 summer's growth were distributed as follows: Rock bass, 20,750; black 

 bass, 40; carp, 700; goldfish, 2,649. The goldfish commenced spawning 

 this year March 24, and the carp April 27. 



From the rainbow-trout eggs hatched at the station the past season 

 there are on hand, in good condition, 80,000 fmgerlings. The bulk of 

 these fish are being reared in the troughs where they were hatched. 



The maximum and minimum temperatures of air and water during 

 the months of November (twenty-six days), December, January, and 

 February (twenty days), were as follows:

Put-in-Bay Station, Ohio (J. J. Stranaiian, Superintendent). 



The work of this station during the year was chiefly confined to the 

 whitefish, pike perch, and lake herring. The egg-collecting season for 

 whitefish and herring was one of the worst in the history of the com- 

 mercial fisheries of Lake Erie. A very severe gale set in on Novem- 

 ber 12, which lasted, with the exception of November 10 and 20, to the 

 close of the spawn-taking season, thereby greatly interfering with the 

 collecting work. 



Whitefish. — The first whitefish eggs were taken November 7, and the 

 last November 29. The places and the number of eggs taken at each 

 were: North Bass Island, 24,780,000; Middle Bass Island, 4,800,000 ;
