FIRST REPORT OF THE IOWA FISH COMMISSIONERS. 



The first report of the Iowa Fish Commissioners, for the 

 years 1874 and 1875, gives an account of their organiza- 

 tion for the purpose of carrying out the trusts confided to 

 them. 



Among the first business transacted by them was the es- 

 tablishment of a hatching-house near Anamosa, under direc- 

 tion of B. F. Shaw. In this much work has already been 

 done in the way of hatching out spawn of California salmon 

 and other useful fishes. The total amount of sj^awn handled 

 and offish distributed by the state, consisting of California 

 salmon, Penobscot salmon, etc., was nearly two millions, of 

 which a good account, it is hoped, will be received in future 

 years.
