A team of top US fisheries scientists has joined the US government in demanding a retraction of a controversial scientific paper that alleges a significant portion of Alaska salmon, crab and pollock is entering the Japanese market from illegal, unreported and unregulated (IUU) fisheries.

The group of six US academic scientists familiar with Alaska fisheries and led by preeminent fisheries scientist Ray Hilborn of the University of Washington recently sent a letter to the journal Marine Policy saying the paper, Estimates of illegal and unreported seafood imports to Japan, should be retracted.
