160 Salmon at the Antipodes. 



CHAPTEE XIX. 



THE GBOWTH AND DEVELOPMENT OP THE 

 SALMONHME. 



The salmon, the trout, and sea trout, in their 

 early stages, grow at nearly the same rate for 

 the first year, the sea trout being rather more 

 advanced. In each of the three varieties 

 mentioned, however, the rate of growth is 

 most unequal in individuals of the same age. 

 If 100 ova of brown trout be taken from 

 the same fish, and hatched out at the same 

 time, at 12 months old some of the young 

 fish will have grown to eight inches in 

 length, while others will not have reached 

 four inches. The same curious difference in 

 tbe growth of individuals has been observed 

 in salmon and salmon trout. 



In no other animal is the difference in the 

 rate of growth of specimens of the same age, 

 and subject to the same conditions, so marked 

 as in the salmonidse.
