Careful Consumption Alone Can't Save the World's Fish

With fish suppliers changing the names of seafood to avoid catch limits, the only way to preserve fish stocks is by electing politicians committed to conservation and tight regulation.

I recently read the Whitefish Handbook of Ecuador, a book that describes the fish Ecuador markets for export. On the page dedicated to South Pacific hake, the writer divulged that hake filets are marketed and sold as flounder, weakfish and tilapia. Hake sold as tilapia?

You know tilapia -- it is one fish everyone agrees is sustainable not least because it's farmed and grows on a vegetarian diet (so it does not require fish in its feed). Tilapia is included in the "best choices" column on seafood wallet cards, which indicate the best and worst species to eat. For years, environmental and health organizations have stressed the benefits of tilapia, and it shows. Indeed, it was recently called "the world's most popular fish." The demand for tilapia is growing -- in the U.S. alone, it has moved up from ninth most consumed fish in 2003 to sixth in 2004. So it might not come as a surprise that there are now tilapia impostors, like this hake.
