Just months after Oceana reported rampant fraud in seafood sold globally, President Obama enacted a measure meant to curb the amount of mislabeled seafood on the market. In early December, his administration put in place rules that would require that every imported fish on a 13-species list be traceable to the boat or fish farm of origin. These species -- which include cod, tuna, and swordfish -- are fish that are especially vulnerable to fraud. 

Now, a group of seafood companies is suing the Obama administration on account of the new rules, which would go into effect in January 2018. The National Fisheries Institute and a half-dozen other industries groups claim the new rules would impose too much of a cost burden on them and that they already do enough to prevent labeling fraud. 

Just this week, researchers from UCLA and Loyola Marymount found that 47% of the fish samples they tested at 26 Los Angeles sushi restaurants between 2012 and 2015 were mislabeled.
