XXII REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



gan Fish Commission, and in January, 1888, a similar number of year- 

 lings were planted in the north branch of Tobacco River, Michigan. 



Loch Leven Trout. 



This fish promises to become very popular for pond culture, being 

 very hardy, and not likely to be attacked by fungus. During the 

 season 17G,730 eggs were taken from GOO fish of this variety. Of this 

 number 50,000 were forwarded to State fish commissions and 85,000 

 hatched out and retained at the station for future distribution. 



ALPENA STATION, MICHIGAN. 



Whitefish. 



A very fair season's work has been done with this fish, notwithstand- 

 ing the fact that no eggs have been obtained from Lake Erie, on which 

 we had previously relied for our greatest supply. The collections this 

 year were made in Lakes Huron and Michigan, the eggs for shipment 

 being forwarded to North ville, and those to be hatched out held at 

 this station. Of the 18,000.000 fry hatched out, 15,000,000 were de- 

 posited in Lake Huron, 1,000,000 in Lake Michigan and 2,000,000 in 

 Long Lake, Michigan. This station is also under the immediate direc- 

 tion of Mr. F. N. Clark. 



Wytheville Station, Virginia, George A. Seagle, Superintendent. 



Rainbow Trout. 



The most noteworthy features in the operation of the station during 

 the season were the increase in the production of eggs of the Rainbow 

 trout and the extensive distribution of yearling fish of this species. The 

 total production of eggs for the season was 300,500, as against 220,500 

 during the previous season. Of the number of eggs produced, 75,700 

 were lost in incubation, 45,000 forwarded to foreign governments, and 

 35,000 to the Commissioners of Fisheries of New Hampshire and West 

 Virginia. The total number of fry released in rearing ponds at the sta- 

 tion was 99,870. Fifteen hundred and thirty-five yearling trout were 

 distributed to seventeen applicants for ponds in Virginia, North Caro- 

 lina, and Tennessee, 11,875 to streams in Virginia and North Carolina, 

 and 5,208 were forwarded to Central Station, Washington, District of 

 Columbia, for distribution. There were also supplied to two applicants 

 for ponds in Virginia 150 trout 3 years old. 



The following is a summary of production and distribution of eggs 

 and yearlings of this species : 



Total number of eggs produced at station 300, 500
