China's growing appetite for high-value seafood, thanks to rapid economic expansion and a burgeoning middle class, could mean there will be less available for the US market this year.

Jake Jacobsen, director of the Inter-Cooperative Exchange, a harvester group that catches 70 percent of the Bering Sea crab quota, told IntraFish Bering Sea king crab that typically goes to the United States, is now being sent to China, much of it as live crab.

"It's a growing market in China, they're very anxious to get crab," he said.
