Fishing Thwarts Antarctic Marine Sanctuary Idea The countries that regulate fishing in the Antarctic have been unable to agree on creating a giant marine sanctuary there. The United States and New Zealand had submitted a joint proposal to protect the Ross Sea, considered one of the most pristine oceans in the world. But some nations remain concerned it would have too much impact on their catches of toothfish, which are marketed as Chilean sea bass. The 24 nations and the European Union finished two weeks of meetings in Australia late on Thursday night without coming to any agreement on the sanctuary proposal. The countries will meet again next July to further consider the idea. Earlier this week, New Zealand and the U.S. finally resolved two years of negotiations over sanctuary boundaries and rules.
