quire a thorough knowledge of these fish if we are to 

 assure their continued and rational utilization. To 

 attain this goal, mutual cooperation between com- 

 mercial and sport fishing interests is necessary. 



Finally, in closing, I would like to express my 

 hope that this international gathering will serve to 

 deepen the understanding between scientists and 

 fishermen of the various nations regarding the future 

 of the billfish resources, and will bring about 

 cooperative effort to advance research as well as 

 fishery endeavors to our mutual advantage.
