A recently published article in the scientific journal Marine and Fishery Sciences (MAFIS) provides valuable information on the migratory patterns of Patagonian toothfish in the Southwest Atlantic Ocean. Through the study, which began in 2004 with the implementation of a tagging and recapture program for the species in the Argentine Sea, a total of 5,907 fish, were tagged and released in areas located on the edge of the shelf and the beginning of the continental slope. Up to the present, 121 individuals have been recaptured, most of them within 50 km of their release site, regardless of the time spent in the wild. Only a few fish exhibited long-distance movements of up to 3,800 km. The findings confirm that Patagonian toothfish in the Argentine Sea, like in other areas, exhibits a marked resident behavior and lacks regular migratory movements involving a significant portion of the stock.
