REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



Broolc troni. — Owiiij? to tlie heavy mortality that had oceiined (lur- 

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

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

 part of Jnly, 1801, l\rr. S. P. Wires, the foreman of the Alpena Station, 

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

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

 he secured 600 S]>ecimens, which were shipped to this station July 14. 

 These readily adapted theniselves 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 Uiiited 

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

 retained at the station for rearing. They began hatching in Januar3^ 

 The average number of eggs i)er 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.
