XLIV REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



Brooli front. — Owing to the lieavy mortality that liad occmred dur- 

 ing the previous spawning season in the breeding fish of this species, 

 it became necessary to replenish the stock. Accordingly, in the early 

 part of July, 1891, Mr. S. P. Wires, the foreman of the Alpena Station, 

 was sent to Grand Marais, Mich., to secure a number of the wild trout 

 from the streams of that vicinity. With the aid of a small force of men 

 he secured 600 specimens, which were shipped to this station July 14. 

 These readily adapted themselves to domestication and suffered no loss. 



On October 19 the spawning season commenced, and continued till 

 January 19. The number of females stripped was 294, 264 males being 

 used. In all, 147,200 eggs were obtained. Of these, 500 were sent to 

 Prof. J. E. Eeighard, at the University of Michigan, and 10,000 to Mr. 

 Mather, at Cold Spring Harbor, N. Y., for reshipment to the United 

 States of Colombia. The balance of good eggs, about 100,000, were 

 retained at the station for rearing. They began hatching in January. 

 The average number of eggs per fish was 500; the largest number 

 obtained from 1 fish being 1,800, on November 28, 1891, and the smallest 

 number, 180. (900 being taken from 5 fish December 7). 



The number of yearlings distributed was 13,000. Of these, 10,000 

 were placed in the stream near the hatchery on October 23, and 3,000 

 sent by car No. 1, on July 24, 1891, to Dubuque, Iowa. 



Loch Leven trout. — The season of spawning of this species was from 

 October 27, 1891, to January 19, 1892. The number of fish spawned 

 was 1,229 (males used, 1,023), which furnished 571,850 eggs. Of these, 

 132,000 were retained at the station for hatching (commencing iu Feb- 

 ruary) and rearing, and the balance of good eggs, 185,500, shipped as 

 follows : 



'Through Fred Mather, Cold Spring Harbor, N. T. 



t Through C. F. Orvis, Manchester, Vt. 



The greatest number of eggs from 1 fish was 1,900, that of 3 fish 

 spawned November 18 being 5,700; the lowest 336, the average of 83 

 fish spawned December 22; the average for the whole take of eggs, 405. 



The distribution of the yearling fish extended from January 17 to 

 March 15, 1892, the number shipped being 3,709, which were consigned 

 to apphcants in Wisconsin, Michigan, Kentucky, and Pennsylvania.
