PERCENTILE PROPORTIONS OF LAKE AND ATLANTIC SALMONS.

TABLE 22— Continued. 



Comparison of Averages of Percentile Proportions of Atlantic and Lake Salmon of the Breeding Season. 



The object of the tables is to show any variations possibly differentiating lake salmon 

 from the Atlantic salmon. The averages of percentile proportions were derived from a 

 basic table of percentile proportions of individual fish. The ranges of total lengths and 

 percentile proportions represented by the averages in these tables overlap more or less. 



Referring to table 21 it is found that the percentile proportions of lake and Atlantic 

 salmon of practically the same average length are divisible into three groups, i.e., (1) 

 those proportions of the lake salmon which are higher than those of the Atlantic salmon ; 

 (2) those of the lake salmon which are lower than those of the Atlantic salmon; and (3) 

 those in which the proportions are equal. For example, in female lake salmon of the aver- 

 age length of 16.5 inches (Class 6f) and female Atlantic salmon of 16.3 in. (Class 5e), 

 it is found that the lake salmon differs from the Atlantic salmon in the following propor- 

 tions :
