Figure 3 



Estimated average annual biomasses (t) of yellowfin tuna (Thunnus albacares) 

 by semi-annual age group for the observed mixture of set types. In the left panel, 

 biomasses are summarized by age within year. In the right panel, biomasses 

 are summarized by year within age group. Age refers to the age in years at the 

 middle of the year.

Figure 4 



Estimated average annual biomasses (t) of yellowfin tuna (Thunnus albacares) 

 by semi-annual age group for all effort directed at non-dolphin (Delphinidae) 

 sets. In the left panel, biomasses are summarized by age within year. In the 

 right panel, biomasses are summarized by year within age group. Age refers to 

 the age in years at the middle of the year.
