What is TUMAS?
• Software we (SPC) are developing to support
fishery management through WCPFC, and SPC
members.
• “Tuna Management Simulator”
– Simulates what might happen to the stock in the future
– Predicts benefits and costs of management options
Where does it fit?
Stock assessment
approved by WCPFC
Management

Other factors
Negotiations
Decisions by nations
and WCPFC
What is it for?
• You run it on your computer
• You can compare the results of different management
options
– What if longline effort decreases by 10%?
– What if the region 3 FAD fishery closes for 3 months?
– How could these options affect stock status, your nation’s
interests, and other nations’ interests?
• To improve understanding and help people
communicate

and negotiate
