Figure 1. The SWFC's Tuna Program is geared to the delivery of tuna 

 management information and advice to U. S. Commissioners 

 and U.S. negotiators. Several functions must be performed 

 to deliver the information required for good management 

 decisions; these functions include stock assessments, 

 economic analysis," data management, analysis of fish envi- 

 ronment interactions and a system analysis function that 

 ties the specialized information together. Research in 

 any or all elements may be required to improve overall 

 quality; management of the program, because of its diver- 

 sity and complexity, is given special consideration.
