from the adults which move about in larger schools. This is clearly 

 an important aspect of the carp problem that should be solved. 



Cole quotes the English ichthyologist Goode,* in regard to the 

 relation of weight to length. One cannot judge of the variation 

 from this table of Goode. The following summary of our observa- 

 tions is in close agreement indicating that the carp grows rapidly 

 but irregularly. Selecting 62 specimens that were five years old the 

 range of weight was from 4 to 11 pounds and the range in length 

 was from 16 to 26 inches.

This variation in the most numerous age taken indicates a larger 

 variation in growth and explains why there is not much significance 

 in the table by Goode.
