the second winter of fishing (December 1954- 

 February 1955) again showed larger fish domi- 

 nating the catch, with 88 percent of the albacore 

 catch larger than 80 cm. The almost complete 

 absence of small albacore (less than 80 cm.) 

 from both the longline and trolling catches dur- 

 ing both winters suggests that the small fish 

 which were present during the fall had nnoved 

 out of the area with the approach of winter.
