extremely short season on highly vulnerable fish, a 

 situation v^^hich did not provide highliners the 

 opportunity to utilize their capabilities and fully 

 develop their tactics and strategies. 



This study has shown that the most successful 

 and least successful fishermen can be character- 

 ized by their activities as well as by the physical 

 parameters of their vessels. Success is not assured 

 by many years of experience, or by a large vessel, 

 although these characteristics are often associated 

 with the most successful fishermen. We agree with 

 Abramson's (1963) suggestion that the fishing 

 power of individual albacore boats is related to 

 intrinsic factors of the captain and crew, in addi- 

 tion to the boat's physical parameters.
