Tuna at the Tsukiji Market John Mahoney
The rich, creamy red meat of the bluefin tuna is prized almost to a cultish degree -- at Tokyo's Tsukiji fish market, a single majestic specimen can sell for over $100,000 -- and as a result the species is severely overfished and endangered. Farming the fish, which might offer a solution, has proven remarkably difficult. After years of experimentation with sexy mood lighting, Australia's Clean Seas company only managed to get them to breed in captivity by injecting them with spear guns full of reproductive hormones. Now, a European initiative has announced an alternative.
