trawler ; IT, 1st class trawler ; 2T, 2nd class trawler ; 

 SN, stake net ; TN, trammel net ; DN, draw net or seine 

 net. The greater number of the fishes returned were 

 recaught by means of trawl nets used by 1st and 2nd class 

 trawlers. In some cases this information as to the method 

 of recapture was not given ; in one or two cases it was also 

 impossible to trace the position of recapture. Whenever 

 possible the fishes were weighed, but very often they had 

 been gutted before being forwarded, so that it was not 

 practicable to estimate the weight in every case. In the 

 case of every fish sent, the otoliths were removed, and are 

 being kept with the object of determining the mode of 

 growth of these structures in relation to the season.
