California fishermen are harvesting the first herring of 2013 in San Francisco Bay this week. The total gillnet quota is 2,690 tons and the fishery will last until March 15, 2013. The historic herring stocks of the past are long gone, but the surge in sustainability and eating locally has sparked the troubled industry. The real value of the herring comes in the from of the roe or eggs, which is a delicacy in Japan. Market prices could improve this year, with smaller harvests predicted in Alaska.
