[25] FAILURES AND SUCCESSES OF FISH-CULTURE. 461 



in Ciiculars of the German Fishery Associa,tioii, 1882 p 71 ) 



Professor Malrngren thinks that there are no reliable data on the 

 reMilts of fish-culture m Canada, and that the undeniable fact of an 

 increase in the luunber of fish must be owing to strict prohibitory meas 

 ures Without attempting to inquire why Professor Malmgreu feels 

 constrained to doubt the reliability of the Canadian reports, I must 

 state that, for my part, I am inclined to believe that the undoubted 

 results are caused by culture and prohibition combined. Why should 

 he increased number of fish be caused only by natural spawning pro- 

 tected by prohibitory measures ! Does Prot^ssor Malmgren not con- 

 mder artificially-produced fry capable of life and development, or does 

 he share the opinion of some people, that only artificially-produced frv 

 but not that which is produced naturally, becomes theffood of largei- 

 hsM I am not able to explain the contradiction in Professor Malm- 

 gren s views, and shall be greatly obliged to any one who will assist 

 me in solving this problem. 



I herewith close this sketch, which gives n.erely an outline of the 

 results which, so far, we have been able to chronicle in the matter of 

 artificial ii«li-cu^ture. The reader may judge for himseli; whether the 

 AC diet which Professor Malmgren has pronounced on artificial fish- 

 culture IS justified by the facts. Let us rejoice in the results reached 

 so far, and not be discouraged by pessimistic views like those expressed 

 by Professor Malmgren, but co.itinue to develop this industry in a 

 rational manner. Quiet labor will find its reward in the future.
