REPORT OP COMMISSIONER OP FISH AND FISHERIES. 



Blade- spotted trout. — The number of this species on hand April 1 was 

 927 of those coming 3 years, and 1,400 of those coming 2 years old. 

 The 3-year-old fish were in excellent condition, but only 62,500 eggs 

 were taken, and for some unknown reason these did not do well, as 

 only about 20 per cent of very weak fry were produced, and nearly 

 all of them died before they commenced to take food readily. Toward 

 the close of the season nearly all the 2 and 3 year old fish died. 

 This was caused by handling them while taking spawn during the very 

 warm weather in May, and partially by the same disease which attacked 

 the brook trout. 



Salmon. — There were received from the World's Fair 40,000 Pacific 

 Coast salmon eggs in very good condition, from which a good percentage 

 hatched. After the sac was absorbed they were planted near Monroe, 

 Mich., in the Easin Eiver, a tributary to Lake Erie. On April 30 there 

 reached the station from Fort Gaston, Cal., 100,000 Pacific Coast salmon 

 eggs, but on opening the package they were found to be all rotten. 



Trout were forwarded from the JSTorthville Station to the World's 

 Fair, as follows: 



Brook, 2 and 3 years old, 100; 1 and 2 years old, 100; yearlings, 300; 

 fingerlings, 2,000. 



Von Behr, 4 years old, 50; fingerlings, 2,000. 



Loch Leven, 4 years old, 50; fingerlings, 2,000. 



Black- spotted, 2 years old, 50. 



Grayling, wild, 189. 



Trout delivered to Michigan Fish Commission: Lake, 1 year old, 25; 

 black-spotted, 1 year old, 25; 2 years old, 25; grayling, wild, 10. 



On January 1G, 20,000 rainbow-trout eggs were received from the 

 Neosho Station, in fair condition. The loss in hatching these and up 

 to the time of the absorption of the sac was 5,000. By the end of the 

 year 8,000 more were lost, leaving 7,000 fingerlings on hand in good 

 condition, which are held for distribution when a year old. 



The following table shows the number of eggs, fry, and fish of each 

 species on hand at the end of the year (June 30, 1894) : 



Alpena Station, Michigan (F. N. Clark, Superintendent). 



The operations of this station during the season were, as in previous 

 years, devoted to the collection of whitefish and lake-trout eggs. The 

 work of securing these commenced about November 1, and continued 

 during the month. The fishing was confined to fewer grounds than 

 formerly, and the severe weather during the spawning seasons of these 

 two species of fish interfered greatly with the work.
