Mercury Risk: High




Call it escolar, butterfish, walu, super white tuna, aburasokomutsu, or whatever you’d like – by any name, this medium-sized ocean fish poses a confounding set of challenges and is problematic at best.  In fact, the commercial sale of escolar is banned in Japan and Italy.  There’s a good reason for that.

First off, escolar is a potential health risk.  In addition to often being chock full of mercury, this fish has a peculiar physiology that is cause for concern.  Escolar contains very high levels of indigestible fatty acids and fatty alcohols known as wax esters. This can cause some degree of gastrointestinal discomfort in a significant percentage of people who eat it. Symptoms range from a slight queasiness to an incapacitating full-on colonic rebellion.

In addition to stomach burbles and potentially embarrassing after-dinner interruptions, those who would eat escolar should be aware of the problems in the fisheries. Escolar is landed all over the globe, but only U.S. fisheries are known to have any sort of management protocols.  Outside of the US, the longliners that bring in escolar kill countless sea turtles, sharks, seabirds, and other animals through their lax regulations and sloppy practices.

Escolar from the United States is a better option than the imported product. Progressive management in Hawaii and the Atlantic has reduced bycatch levels, but there is still no strong understanding of stock strength. Proceed with caution.

Escolar from international sources is a bad idea. Ordering this fish promotes irresponsible practices that decimate fish populations threaten endangered species, and support an opaque fishing regime. On top of it all, you’re quite likely to get sick. It’s best to pass on imported escolar.

It can be difficult to identify sustainable options when dealing with categories of seafood that present many different variables, such as catch method, country of origin, or species variant. It’s important to support seafood merchants that are willing to take these challenges on themselves and source only sustainable options. By allowing precautionary, third-party science to dictate its seafood selection, ilovebluesea.com — the world’s first fully sustainable online seafood marketplace — offers its customers the ability to purchase responsible seafood with confidence.
