Experts say labels should identify salmon and trout

Species may be misrepresented in markets to get a higher price

Experts have called for clear labeling of salmon to avoid misleading consumers, following recent debates over the difference between salmon and trout.

"Traditionally, salmon refers to Atlantic salmon, and it is different from trout," said Gu Zhongyi, a nutritionist at Beijing Friendship Hospital of Capital Medical University. "It is common for trout to be sold as Atlantic salmon, though. Labeling should be regulated so consumers know whether they have bought Atlantic salmon or trout."
