CONCLUSION. 181 



''The artificial reproduction and cultivation of 

 fish, have for some time been practiced in some 

 parts of Europe. In France it is now carried on 

 to considerable extent, and the produce of some of 

 the streams and ponds yields large profits. The 

 subject is now attracting some attention in the 

 United States. The New York State Agricultural 

 Society, in their last premium list, have offered 

 a prize of $100 for the best essay on the 

 Production and Preservation of Domestic Fish for 

 Ponds. 



Drs. Garlick and Ackley, known as distinguish- 

 ed surgeons of Cleveland Ohio, were the first, we 

 believe, to introduce the artificial spawning aid 

 domestication of fish in the United States. Dr. 

 Garlick being an enthusiastic amateur in this line 

 commenced the business in connection with 'his 

 associate Dr. Ackley upon the farm of the latter 

 two or three years ago. They made several 

 trips to Lake Superior and Port Stanley in Can- 

 ada, to procure trout for stocking their streams 

 and in every instance were successful except the 

 first, when they lost a large number of fish in 

 transportation. After this, with personal attention 

 they found that by reducing the temperature of 

 the water in the vessels containing the fish to 

 82 degrees by the application of ice, the respira-

 that they experienced no difficulty in transport-

 this way they have procured at different times 

 150 full grown trout. Feeling an interest in the
