Lucky Lobsters Jam China Flights, Sending U.S. Prices to Record

Every Sunday for the past seven months, about 60,000 live North American lobsters packed in wet newspapers and Styrofoam coolers make the 18-hour flight to Asia in a Korean Air Lines Co. cargo plane.

The 7,500-mile (12,000-kilometer) trip from Halifax, Nova Scotia, to Shanghai via South Korea has become a weekly routine this year with a surge in demand from China, where lobsters caught in North Atlantic waters are at least one-third the cost of competing supplies. As a result, exports have skyrocketed from Canada and the U.S., the world’s top producers, and American prices are the highest ever.
