“But what about our children? When will they think about our children? They will no longer see the kahi [tuna]. It is a disappearing species. We should do something, we should stop this. I know this because I did a month of [longline] fishing. That’s 3,500 hooks in one evening. 3,500 hooks! Mea nui [that’s a lot]…. And the sharks! The sharks! They cut their fins off. This is a massacre. They must really outlaw these thonier. It is true that they have families to feed but… what about the world, eh? Hm? What are we going to eat later on if there are no more fish?”
Tahitian-born Hiro told me about the plight of the tuna one afternoon on the veranda of his home in Motopu, on the island of Tahuata, June 2018. The thonier boats he refers to are large fishing vessels with their eyes set on Tuna (fr. thon). The local mayors council in the Marquesas (known as CODIM) has accepted a new plan to allow thonier to fish in the Marquesan Exclusive Economic Zone (EEZ). When I was doing dissertation research on the island of Tahuata, the thonier had not yet arrived, but I found that already the majority of people I spoke with were against these huge boats. Like Hiro, many islanders fear the population of tuna and other species (like sharks) will be decimated. In contrast, others for the program, like the mayor of Vaitahu, are drawn to the project by the potential economic benefits. Today – as a friend from the island tells me through Facebook messenger – the first thonier has arrived at the port of Tahuata’s neighboring island, Hiva Oa. However, protesters continue to show their discontent and the project seems to be at a standstill.
Thonier employ a fishing method called “longline” where lines potentially 100 miles long are strung throughout the ocean supported by buoys. As Hiro says, over 3,000 hooks can be deployed in a single night with this method (see Fitzgerald 2013 for an in-depth description). In his book Tuna: A Love Story journalist Richard Ellis calls this method “ruthlessly efficient.” The by-catch associated with these lines is immense, as anything willing to bite into a large chunk of bait meant is at risk, as well as those who happen to tangle themselves in the line, such as sea birds.
Tuna populations have declined immensely since the demand for this fish has exploded, due to the Japanese sushi market and canned tuna fisheries. I won’t talk about percentages and numbers here, because there are many depending on the species and the geographical location, but if you’re interested in learning more about the sustainability of Tuna fisheries I suggest reading anything by Barbara Block, Carl Safina or Sylvia Earle, as well as Richard Ellis’s book mentioned above (although it’s a bit old). Greenpeace, WWF and FAO also have some important, more statistical information for those interested. More to be said about Tuna and fishing in upcoming posts, I’m sure.
