Recaptured 



on their 

 second return 



The recaptures of " wired " smolts up to the end of the netting season of 

 1909 would seem to number 105, of which only four are specially described 

 as being on their second return, though it is possible that a few of the 

 older fish, whose scales I have had no opportunity of examining, ma}' also 

 have been in the river before. 



Apart from the irregular periods of the smolts' return as maiden salmon, 

 which subject has already been dealt with, the chief point of interest to be 

 noted in the above Tables is the maximum weight to which fish of certain 

 ages may attain, and it will be seen that there is a remarkable correspon- 

 dence between those indicated by scale examination and the actual results 

 of marking, more especially in the case of the large autumn and spring 

 fish. In the former class salmon up to 28 lbs. were found to be maiden 

 fish from the scale indications, and a " wired " recapture was made weighing- 

 only one pound less. In the latter class a fish of 32 J lbs. was the largest 

 maiden salmon of which a scale was examined, and this heavy weight at 

 five years old was surpassed when a ' 'wired" 35-pounder was taken in 

 1908. The number of recaptures of large spring fish is comparatively 

 small, and I can only look upon this as accidental and in no way
