recent liberal plants will, I have every reason to believe, permanently 

 establish the species in these waters. The experiment is not without a 

 successful precedent, the species having already been introduced and 

 acclimatized, in this way, in waters of the same character in Kalkaska 

 County, this State. Quite a number of adult specimens were taken 

 from the waters referred to during the past year. 



BROOK TROUT. 



Our brook trout work was, on the whole, quite satisfactory. In all, 

 473,000 eggs were obtained, from which 357,000 eggs were shipped, and 

 50,000 fry hatched. Of the latter, 15,000 were delivered to the Ohio 

 Fish Commission, April 10; the remainder were on hand at the hatchery 

 at the close of the period covered by this report, though a few small 

 shipments have since been made. 



Between twenty and twenty-five thousand eggs were obtained from 

 wild trout running up the waste stream from the ponds, which forms a 

 natural raceway connecting with a branch of the Eiver Eouge, a small 

 stream well stocked with trout. Over 300 of these fish, of various 

 sizes, and mostly males, were captured. 



From the tables which follow it will be seen that 97,150 eggs were 

 obtained from 422 spawners, 20 months old, an average of 230 eggs 

 each; 184,660 eggs from 274 spawners, 30 months old, an average of 

 674; 168,700 eggs from 120 spawners, 42 and 54 months old and upwards, 

 an average of 1,406 ; and 22,500 from 43 wild trout, an average of 524,
