Save Our Oceans, Eat Like a Pig

By Jennifer Jacquet, The Tyee. Posted April 20, 2007.

Thirty-six per cent of all marine fish caught are used to feed animals, according to a new study on forage fish from the Sea Around Us project at the University of British Columbia's Fisheries Center. "Forage fish" were so named because they often wind up as meals for other fish, marine mammals, or birds. Today we catch 30 million tonnes of these small, wild fish and grind them up into fish meal and oil to feed chicken, fish, and pigs.

Dr. Daniel Pauly, co-author of the report with Drs. Jackie Alder and Reg Watson, has come to disagree with the label "forage fish," which he views as synonymous with waste. "We should never have followed the fish meal industry on the slippery slope of naming edible fish 'forage fish' in the first place," says Pauly. "These fish could provide humans with large quantities of protein but we waste them by using them as raw material for fish meal."

A half-century ago, less than ten per cent of fish caught were used to make into fish meal. Pigs and chickens were fed mostly grains and fish farming was a cottage industry. Today, with fisheries in much dire straits and a heightened awareness about global malnutrition, why are we turning more than one-third of our marine fish into powdered pig feed? One part of the answer is that fish meal is price competitive with soymeal and other grain feeds because the fish are caught in developing countries willing to take low prices for the fish.

The other part of the answer is that, particularly in the Americas, many of the "forage fish" species, such as blue whiting, herring, sardines and anchovies have simply gotten a bad rap. These little fish are perfectly tasty but need a facelift in the marketplace. Consumers and governments must be convinced that it is more efficient, lucrative, and ecological to instead feed pigs, chickens, and fish a plant-based diet -- and for people to forage on forage fish instead. The price for such fish will rise as they are used for table fish rather than fish meal, and the result might well be fewer fish scoured from oceans, more people better fed, and more income for developing nations.

Enter Dr. Patricia Majluf from Lima, Peru.

Extreme fish makeover

Majluf works with fur seals and penguins off the Peruvian coast, where she "saw an ever reducing resilience to El Nino events in these populations, largely due to availability of Peruvian anchovy."

The Peruvian anchovy fishery began around 1950 and since then has contributed, at times, up to half of the world's fish meal. Much of this fish meal is used to feed farmed fish farms in China as well as livestock and farmed salmon ("floating pig farms" says Pauly).

Yet, as Peru exports roughly 8 to 10 million tonnes of anchovy each year, half of its population, 15 million people, lives under conditions of critical poverty. Majluf found it illogical that Peru has 25% infantile malnourishment and yet "millions of tons of fish is taken from the ocean and fed to pigs and fish."

"But Peruvians are finicky eaters," explained Majluf. "The government had been trying to get them to eat anchovies for years and they made some pretty nasty products that didn't taste good."
