Escapement of bachelors from the commercial kill 


Esceapement of 3-year males in 1950 
Through-—the-season escapement.—The number of 3-year males spared 
by the clubbers on St. St. Paul in 1950 ¢ as : being offsize (under 41 or over 45 
inches) may be estimated from the A-tag return in either of two ways: by 
comparing the length distribution in the kill and in the tagged animals, 
or by comparing the returns of tagged and tag-lost animals. 
Method 1, Comparison of tagged and tag-lost seals: As noted in 
the headnote to table 19, clubbers made a special effort to take every 
tagged animal so that the tag recoveries should be representative of the 
three-year-old class. On the other hand it may be assumed that the tag- 
lost group is representative of the commercial kill. In 1950 the proportion 
of tagged to tag-lost animals in the 41- to 45-inch range (in which range 
all male seals were taken) was 1071 or 2.64 (tables 23 and 24). The "excess 
kill" in 195U resulting from 406 the taking of small and large seals 
simply because they were tagged is 114, obtained as follows:
