Recapture encounters have revealed Atlantic blue marlin completing transatlantic, transequatorial, and interoceanic movements, while white marlin have demonstrated transatlantic crossings (Ortiz et al.
Our study was conducted to analyze currently available CTC and TBF mark-recapture data to define and quantify movement patterns and seasonality of Atlantic blue marlin, white marlin, and sailfish in association with ICCAT management areas and U.
The movements of Atlantic blue marlin, white marlin, and sailfish, derived from the conventional tag recaptures, support the currently accepted ICCAT boundary definitions for delineating stock structure.
Yokawa and Uozumi, 2001; Uozumi, 2003), that the relatively low Atlantic blue marlin CPUE's obtained by this fishery since the 1980's were not indicative of low population levels, but rather were artifacts of changes in fishing practices.
Uozumi and Nakano (1994) and Uozumi (2003) have not contested that Atlantic blue marlin and white marlin stocks were larger during the 1960's than at any point since.
Although the Atlantic blue marlin stock is also considered to be overexploited, its status is not as precarious as that of white marlin (ICCAT, 2001).

The relatively high rate of survival of blue marlin inferred from these data for five and thirty days following release from pelagic longline gear demonstrates that management measures requiring live release, such as those recently adopted by ICCAT, can significantly reduce fishing mortality on Atlantic blue marlin.
Examination of our results suggests that there are several other molecular markers, which while not used in this study, occur at relatively high frequencies in Atlantic blue marlin, sailfish, and white marlin but do not occur in their Pacific conspecifics.
In the most recent assessment of Atlantic blue marlin (ICCAT, 2001), the Standing Committee for Research and Statistics (SCRS) of the International Commission for the Conservation of Atlantic Tunas (ICCAT) estimated the current biomass of blue marlin to be about 40% of that required for maximum sustainable yield (MSY).
