Tuna Trouble: Greenpeace Sets its Sights on Bycatch
This week, the Hillman Foundation gave the August Sidney Award to Tom Gogola for his story “Bycatch 22,” which reveals how dysfunctional fishing regulations force fishermen to throw tons of perfectly good “bycatch” fish overboard. Bycatch is anything a fisher catches while fishing for something else. Gogola explains how misguided regulations force fishermen to waste fish in the name of conservation. He also describes innovative new government-funded research to reduce bycatch of fish, turtles, and seabirds.
In other bycatch news, Greenpeace launched a major new campaign against bycatch in the tuna industry this week. The centerpiece of the campaign is a satirical video entitled, “The Tuna Industry’s Dirty Little Secret,” featuring artwork by Pulitzer Prize-winning cartoonist Mark Fiore. The campaign takes aim at Starkist, Chicken of the Sea, and Bumble Bee–major suppliers of supermarket tuna.
In a post about the campaign at Lawyers Guns and Money, Eric Loomis chides pescetarians (vegetarians who make exceptions for fish), arguing that eating large marine fish in this day and age is the equivalent of chowing down on passenger pigeons in 1850. That’s hyperbole. Not all marine fisheries are mismanaged.
However, as Greenpeace reveals, the fishers who supply canned tuna to supermarkets have a lot to answer for. One of the main offenders is a simple technology known as a fish aggregating device, or FAD. To you and me, an FAD is a buoy; but to sea creatures, an FAD is an irresistable marine block party. Fish are instinctively attracted to floating debris. Unfortunately, it’s not just tuna that are drawn to these floats, according to the Greenpeace website:
FADs increase bycatch in the skipjack tuna industry by between 500% and 1000% when compared to nets set on free-swimming schools (FAD-free seining.) To make matters worse, between 15 percent and 20 percent of the total catch of a FAD-associated skipjack seine is actually juvenile yellowfin and bigeye – two species of tuna that are in serious trouble and cannot afford to have their young purloined before they ever have a chance to breed. The total content of bigeye and yellowfin in FAD-free skipjack seines is less than 1 percent.
Sashimi-lovers take note. The canned tuna industry is strangling yellowfins and bigeyes in their infancy.
