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

By Jennifer Jaquet, The Tyee. Posted February 24, 2007.

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.

Pacific hake is a carnivorous fish caught in the open ocean by industrial fishing vessels trailing longlines that accidentally snag turtles, sharks and seabirds. Hake is a far cry from tilapia, but your taste buds can't tell.

And hake isn't the only impostor. Many seafood species, after being renamed or mislabelled, masquerade in the market as eco-friendlier or tastier or more appetizing versions of their former selves. What does this mean for environmental groups working to save the oceans relying on the "ecology of commerce"?

Perceived power of the pocketbook

With the collapse of fish stocks and increase in concern for the oceans, non-government organizations (NGOs) have launched a variety of seafood related social marketing campaigns, most dealing with what to eat, ranging from eco-labelling to the explicit boycott of certain products.

The most prominent seafood label, plastered on tuna cans since the 1990s, is the "dolphin safe" logo for tuna products. Another well-established seafood label that is widely discussed is that of the Marine Stewardship Council (MSC). In addition to eco-labels, many NGOs launched campaigns to influence consumer behaviour, such as "Give Swordfish a Break" or the "Farmed and Dangerous" salmon campaign. NGOs and aquariums have also released seafood wallet cards for consumers to consult at the grocery store or restaurant.

The fundamental goal of these campaigns is to foster a consumer consciousness that steers seafood demand to support healthy fish stocks. But a number of impediments stand between these campaigns and their success.

Let's call a snapper a snapper

For one, as in the case of masquerading hake, eco-marketing is undermined by mislabelling strategies. A widespread campaign in Europe raised awareness of the negative effects of farm-raised shrimp. So Thai shrimp, which account for nearly 30 per cent of global production, are now exported with the label "wild-caught" rather than "farm-raised." In the U.K., illegally caught cod is labelled as "ling."

Renaming species further complicates efforts by seafood advocacy groups. Three-quarters of the fish sold in the U.S. as "red snapper" belong to some other species. Rock crab, once thrown overboard because it was considered of no value, is now marketed and sold as "peekytoe crab." The Patagonian toothfish, an endangered species, is marketed as Chilean sea bass. Slimeheads were renamed a more palatable orange roughy.

Mislabelling species is dishonest and also gives consumers the false sense that supply is meeting demand. Shark flesh is stamped to make "faux scallops." The common skate, which once provided many savoury restaurant meals, is nearly extinct in the North Sea, so thornback rays are sold as skate. In Ecuador, shark will be filleted and sold as flounder or tuna. But lack of traceability in the marketplace is less of a problem than the market itself.

Up against a global appetite

U.S. citizens consumed half a kilogram more seafood per capita in 2004 than they did in 2002. In fact, almost everyone is eating more seafood. Since the early 1960s, worldwide per capita fish consumption has been growing steadily at 3.6 per cent per year. Over this time, per capita fish consumption has doubled.
