130 A IVEW METHOD OF PROTECTIIVG THE EGGS OF CARP ANI> 



REARING T5IE AOli^G. 



By L,. T. liVHEELER. 



[From a letter to Prof. S. F. Baird.] 



I have now had three years and a half experience in the raising and 

 hatching of German carp, and it may be that my experiments may be 

 worth something to others, particularly in the South. 



All still-water ponds should be as deep as possible so as to prevent 

 stagnation and to insure a certain supply of water when the rainfall 

 is alone to be depended upon. 



As it is next to impossible to keep out native fish, I had to resort to 

 partially artificial means to hatch and protect carp. I have adopted 

 the following plan with eminent success : 



About the 1st of May, having first procured a quantity of long sea- 

 moss, I tie it in small bunches and lay it in shallow water near the bank, 



* These figures were taken from the account furnished by the clerk of the steamer.
