Task Force on Human Trafficking in Fishing in International Waters: Report to Congress [open pdf - 933KB]
From the Introduction: "This report describes the United States government's authorities and gaps in its authorities with respect to combating human trafficking in fishing in international waters. This report will also provide recommendations to address those gaps. Due to the varying jurisdictional and legal issues that arise depending on the nexus to the United States, the report is organized to address three scenarios: (1) human trafficking on U.S.-flagged vessels ('U.S. vessels'); (2) human trafficking on foreign-flagged vessels ('foreign vessels') whose catch enters U.S. markets; and (3) human trafficking on foreign vessels whose catch does not enter U.S. markets."
