400-day returns (15), the logged take of yellowfin tuna 5 

 within a radius of 250 n.mi. and a radius of 250 to 600 

 n.mi. during the period after 50 days following release 

 and before capture, or after 200 days and before recap- 

 ture, respectively (Table 7) (catch of yellowfin tuna is the 

 closest correlate of actual tag recapture effort (i.e., 

 number of dolphins captured) for which data of suffi-
