Sardine scare

摘要

Western Canada's sardine fleet returned with no fish this month. The loss of the fishery, normally worth CAN$32 million (US$30.7 million), took many by surprise. Yet researchers warned last year that it could happen. There are still sardines off the US Pacific coast. But the vanishing of the Canadian fish is part of a process that could mean they all disappear for decades, says Juan Zwolinski of the University of California at Santa Cruz.
